PREFACE (continued 5)

Now, the true flowers of the arum and all its spadix-bearing kin are so minute that one scarcely notices them where they are clustered on the club-shaped column in the center of the apparent "flower." The beautiful white banner of the marsh calla, or the green and maroon striped pulpit from which Jack preaches, is no more the flower proper than the papery sheath below the daffodil is the daffodil. In the arum the white advertisement flaunted before flying insects is not even essential to the florets' existence, except as it helps them attract their pollen-carrying friends. Almost all waterside plants, it will be noticed, depend chiefly upon flies and midges, and these lack aesthetic taste. "Such plants have usually acquired small and inconspicuous separate flowers," says Grant Allen; "and then, to make up for their loss in attractiveness, like cheap sweetmeats, they have very largely increased their numbers. Or, to put the matter more simply and physically, in waterside situations those plants succeed best which have a relatively large number of individually small and unnoticeable flowers massed together into large and closely serried bundles. Hence, in such situations, there is a tendency for petals to be suppressed, and for blossoms to grow minute; because the large and bright flowers seldom succeed in attracting big land insects like bees or butterflies, while the small and thick-set ones usually do succeed in attracting a great many little flitting midges." Flies, which are guided far more by their sense of smell than by sight, resort to the petalless, insignificant florets of the ill-scented marsh calla in numbers; and as the uppermost clusters are staminate only, while the lower florets contain stamens and pistil, it follows they must often effect cross-pollination as they crawl over the spadix. But here is no trap to catch the tiny benefactors such as is set by wicked Jack-in-the-pulpit, or the skunk-cabbage, or another cousin, a still more terrible executioner, the cuckoo-pint (Arum maculatum) of Europe.

Few coroner's inquests are held over the dead bodies of our feathered friends; and it is not known whether the innocent-looking marsh calla really poisons the birds on which it depends to carry its bright seeds afar or not. The cuckoo-pint, as is well known, destroys the winged messenger bearing its offspring to plant fresh colonies in a distant bog, because the decayed body of the bird acts as the best possible fertilizer into which the seedling may strike its roots. Most of our noxious weeds, like our vermin, have come to us from Europe; but Heaven deliver us from this cannibalistic pest!

The very common GREEN ARROW-ARUM (Peltandra Virginica), found in shallow water, ditches, swamps, and the muddy shores of ponds throughout the eastern half of the United States, attracts us more by its stately growth and the beauty of its bright, lustrous green arrow-shaped leaves (which have been found thirty inches long), than by the insignificant florets clustered on the spadix within a long pointed green sheath that closely enfolds it. Pistillate florets cover it for only about one-fourth its length. To them flies carry pollen from the staminate florets covering the rest of the spadix. After the club is set with green berries - green, for this plant has no need to attract birds with bright red ones - the flower stalk curves, bends downward, and the pointed leathery sheath acting as an auger, it bores a hole into the soft mud in which the seeds germinate with the help of their surrounding jelly as a fertilizer.

AMERICAN WHITE HELLEBORE; INDIAN POKE; ITCH-WEED (Veratrum viride) Bunch-flower family

Flowers - Dingy, pale yellowish or whitish green, growing greener with age, 1 in. or less across, very numerous, in stiff-branching, spike-like, dense-flowered panicles. Perianth of 6 oblong segments; 6 short curved stamens; 3 styles. Stem: Stout, leafy, 2 to 8 ft. tall. Leaves: Plaited, lower ones broadly oval, pointed, 6 to 12 in. long; parallel ribbed, sheathing the stem where they clasp it; upper leaves gradually narrowing; those among flowers small. Preferred Habitat - Swamps, wet woods, low meadows. Flowering Season - May-July. Distribution - British Possessions from ocean to ocean; southward in the United States to Georgia, Tennessee, and Minnesota.

"Borage and hellebore fill two scenes - Sovereign plants to purge the veins Of melancholy, and cheer the heart Of those black fumes which make it smart."

Such are the antidotes for madness prescribed by Burton in his "Anatomie of Melancholy." But like most medicines, so the homeopaths have taught us, the plant that heals may also poison; and the coarse, thick rootstock of this hellebore sometimes does deadly work. The shining plaited leaves, put forth so early in the spring they are especially tempting to grazing cattle on that account, are too well known by most animals, however, to be touched by them - precisely the end desired, of course, by the hellebore, nightshade, aconite, cyclamen, Jamestown weed, and a host of others that resort, for protection, to the low trick of mixing poisonous chemicals with their cellular juices. Pliny told how the horses, oxen, and swine of his day were killed by eating the foliage of the black hellebore. Flies, which visit the dirty, yellowish-green flowers in abundance, must cross-fertilize them, as the anthers mature before the stigmas are ready to receive pollen. Apparently the visitors suffer no ill effects from the nectar. We nave just seen how the green arrow-arum bores a hole in the mud and plants its own seeds in autumn. The hellebore uses its auger in the spring, when we find the stout, shining, solid tool above ground with the early skunk-cabbage.

STAR OF BETHLEHEM; TEN O'CLOCK (Ornithogalum umbellatum) Lily family

Flowers - Opening in the sunshine, white within, greenish on the outside, veined, borne on slender pedicels in an erect, loose cluster. Perianth of 6 narrowly oblong divisions, 1/2 in. long or over, or about twice as long as the flattened stamens; style short, 3-sided. Scape: Slender, 4 to 12 in. high, with narrow, blade-like bracts above. Leaves: Narrow, grass-like with white midvein, fleshy, all from coated, egg-shaped bulb. Preferred Habitat - Moist, grassy meadows, old lawns. Flowering Season - May-June. Distribution - Escaped from gardens from Massachusetts to Virginia.

The finding of these exquisite little flowers, growing wild among the lush grass of a meadow not far from some old homestead where their ancestors, with crocuses and grape hyacinths, once brightened the lawn in early spring, makes one long to start a Parkinson Society instantly. Some school children not far from New York, receiving their inspiration from Mrs. Ewing's little book, "Mary's Meadow," have spread the gospel of beauty, like the true missionaries they are, by systematically planting in lanes and fields sweet violets, golden coreopsis, hardy poppies, blue corn-flowers, Japanese roses, orange day-lilies, larkspurs, and many other charming garden flowers that need only the slightest encouragement to run wild. Immense quantities of seed, that go to loss in every garden, might so easily be sprinkled at large on our walks. Nearly all the beautiful hardy perennials cultivated here grow in Nature's garden in Europe or Asia, and will do so in America if they are but given the chance. The Star of Bethlehem is a case in point. Several members of the large group of charming spring flowers to which it belongs grow in such abundance in the Old World that for centuries the bulbs have furnished food to the omnivorous Italian and Asiatic peasants. If we cannot spare offsets from the garden, and will wait a few years for seeds to bear, the rich, light loam of our grassy meadows, too, will be streaked with a Milky Way of floral stars, as they are in Italy.

The Greek generic name of the Star of Bethlehem, meaning "bird's milk" (a popular folk expression in Europe for some marvellous thing) was applied by Linnaeus because of the flower's likeness to the wonderful star in the East which guided the Wise Men to the manger where Jesus lay.

STAR-GRASS; COLIC-ROOT (Aletris farinosa) Lily family

Flowers - Small, oblong-tubular, pure white or yellowish, about 1/4 in. long, set obliquely in a long, wand-like, spiked raceme, at the end of a slender scape 2 to 3 ft. tall. Perianth somewhat bell-shaped, 6-pointed, rough or mealy outside; 6 stamens, inserted below each point; style 3-cleft at tip. (A Southern form or distinct species (?) has yellower, fragrant flowers.) Leaves: >From the base, lance-shaped, 2 to 6 in. long, thin, pale yellowish green, in a spreading cluster. Preferred Habitat - Dry soil; roadsides; open, grassy, sandy woods. Flowering Season - May-July. Distribution - From Ontario and the Mississippi eastward to the Atlantic.

Herb gatherers have searched far and wide for this plant's bitter, fibrous root, because of its supposed medicinal virtues. What decoctions have not men swallowed from babyhood to old age to get relief from griping colic! In partial shade, colonies of the tufted yellow-green leaves send up from the center gradually lengthening spikes of bloom that may finally attain over a foot in length. The plant is not unknown in borders of men's gardens. The Greek word (aletron = meal) from which its generic title is derived, refers to the rough, granular surface of the little oblong white flower.

WILD SPIKENARD; FALSE SOLOMON'S SEAL; SOLOMON'S ZIG-ZAG (Vagnera racemosa; Smilacina racemosa of Gray) Lily-of-the-Valley family

Flowers - White or greenish, small, slightly fragrant, in a densely flowered terminal raceme. Perianth of 6 separate, spreading segments; 6 stamens; 1 pistil. Stem: Simple, somewhat angled, 1 to 3 ft. high, scaly below, leafy, and sometimes finely hairy above. Leaves: Alternate and seated along stem, oblong, lance-shaped, 3 to 6 in. long, finely hairy beneath. Rootstock: Thick, fleshy. Fruit: A cluster of aromatic, round, pale red speckled berries. Preferred Habitat - Moist woods, thickets, hillsides. Flowering Season - May-July. Distribution - Nova Scotia to Georgia; westward to Arizona and British Columbia.

As if to offer opportunities for comparison to the confused novice, the true Solomon's seal and the so-called false species - quite as honest a plant - usually grow near each other. Grace of line, rather than beauty of blossom, gives them both their chief charm. But the feathery plume of greenish-white blossoms that crowns the false Solomon's seal's somewhat zig-zagged stem is very different from the small, greenish, bell-shaped flowers, usually nodding in pairs along the stem, under the leaves, from the axils of the true Solomon's seal. Later in summer, when hungry birds wander through the woods with increased families, the wild spikenard offers them branching clusters of pale red speckled berries, whereas the latter plant feasts them with blue-black fruit, in the hope that they will drop the seeds miles away.

By clustering its small, slightly fragrant flowers at the end of its stem, the wild spikenard offers a more taking advertisement to its insect friends than its cousin can show. A few flies and beetles visit them; but apparently the less specialized bees, chiefly those of the Halictus tribe, which predominate in May, are the principal guests. These alight in the center of the widely expanded blossoms set on the upper side of the branching raceme so as to make their nectar and pollen easily accessible; and as the newly opened flower has its stigma already receptive to pollen brought to it while its own anthers are closed, it follows the plant is dependent upon the bees' help, as well as the birds', to perpetuate itself.

The STAR-FLOWERED SOLOMON'S SEAL (V. stellata), found from the Atlantic to the Pacific, from Newfoundland as far south as Kansas, has larger, but fewer, flowers than the wild spikenard, at the end of its erect, low-growing stem. Where the two species grow together - and they often do - it will be noticed that the star-flowered one frequently forms colonies on rich, moist banks, its leaves partly clasp the stem, and its berries, which may be entirely black, are more frequently green, with six black stripes.

The TWO-LEAVED SOLOMON'S SEAL, or FALSE LILY-OF-THE-VALLEY (Unifolium Canadense), very common in moist woods and thickets North and West, is a curious little plant, sometimes with only a solitary, long-petioled leaf; but where many of these sterile plants grow together, forming shining beds. Other individuals lift a white-flowered raceme six inches above the ground; and on the slender, often zig-zagged flowering stem there may be one to three, but usually two, ovate leaves, pointed at the apex, heart-shaped at the base, either seated on it, one above the other, or standing out from it on distinct but short petioles. This flower has only four segments and four stamens. Like the wild spikenard, the little plant bears clusters of pale red speckled berries in autumn.

HAIRY or TRUE or TWIN-FLOWERED SOLOMON'S SEAL (Polygonatum biftorum) Lily-of-the-Valley family

Flowers - Whitish or yellowish green, tubular, bell-shaped, 1 to 4, but usually 2, drooping on slender peduncles from leaf axils. Perianth 6-lobed at entrance, but not spreading; 6 stamens, the filaments roughened; 1 pistil. Stem: Simple, slender, arching, leafy, 8 in. to 3 ft. long. Leaves: Oval, pointed, or lance-shaped, alternate, 2 to 4 in. long, seated on stem, pale beneath and softly hairy along veins. Rootstock: Thick, horizontal, jointed, scarred. (Polygonatum = many joints). Fruit: A blue-black berry. Preferred Habitat - Woods, thickets, shady banks. Flowering Season - April-June. Distribution - New Brunswick to Florida, westward to Michigan.

>From a many-jointed, thick rootstock a single graceful curved stem arises each spring, withers after fruiting, and leaves a round scar, whose outlines suggested to the fanciful man who named the genus the seal of Israel's wise king. Thus one may know the age of a root by its seals, as one tells that of a tree by the rings in its trunk.

The dingy little cylindric flowers, hidden beneath the leaves, may be either self-pollenized or cross-pollenized by the bumblebees to which they are adapted. "We may suppose," says Professor Robertson, "that the pendulous position of the flowers owes its origin to the fact that it renders them less convenient to other insects, but equally convenient to the higher bees which are the most efficient pollinators; and that the resulting protection to pollen and nectar is merely an incidental effect." Certain Lepidoptera, and small insects which crawl into the cylinder, visit all the Solomon's seals.

The SMOOTH SOLOMON'S SEAL (P. commutatum; P.giganteum of Gray), with much the same range as its smaller relative, grows in moist woods and along shaded streams. It is a variable, capricious plant, with a stout or slender stem, perhaps only one foot high, or again towering above the tallest man's head; the oval leaves also vary greatly in breadth and length; and a solitary flower may droop from an axil, or perhaps eight dingy greenish cylinders may hang in a cluster. But the plant is always smooth throughout. Even the incurved filaments which obstruct the entrance to this flower are smooth where those of the preceding species are rough-hairy. The style is so short that it may never come in contact with the anthers, although the winged visitors must often leave pollen of the same flower on the stigma.

EARLY or DWARF WAKE-ROBIN (Trillium nivale) Lily-of-the-Valley family

Flowers - Solitary, pure white, about 1 in. long, on an erect or curved peduncle, from a whorl of 3 leaves at summit of stem. Three spreading, green, narrowly oblong sepals; 3 oval or oblong petals; 6 stamens, the anthers about as long as filaments; 3 slender styles stigmatic along inner side. Stem: 2 to 6 in. high, from a short, tuber-like rootstock. Leaves: 3 in a whorl below the flower, 1 to 2 in. long, broadly oval, rounded at end, on short petioles. Fruit: A 3-lobed reddish berry, about 1/2 in. in diameter, the sepals adhering. Preferred Habitat - Rich, moist woods and thickets. Flowering Season - March-May. Distribution - Pennsylvania, westward to Minnesota and Iowa, south to Kentucky.

Only this delicate little flower, as white as the snow it sometimes must push through to reach the sunshine melting the last drifts in the leafless woods, can be said to wake the robins into song; a full chorus of feathered love-makers greets the appearance of the more widely distributed, and therefore better known, species.

By the rule of three all the trilliums, as their name implies, regulate their affairs. Three sepals, three petals, twice three stamens, three styles, a three-celled ovary, the flower growing out from a whorl of three leaves, make the naming of wake-robins a simple matter to the novice. Rarely do the parts divide into fours, or the petals and sepals revert to primitive green leaves. With the exception of the painted trillium which sometimes grows in bogs, all the clan live in rich, moist woods. It is said the roots are poisonous. In them the next year's leaves lie curled through the winter, as in the iris and Solomon's seal, among others.

One of the most chastely beautiful of our native wild flowers - so lovely that many shady nooks in English rock-gardens and ferneries contain imported clumps of the vigorous plant - is the LARGE-FLOWERED WAKE-ROBIN, or WHITE WOOD LILY (T. grandiflorum). Under favorable conditions the waxy, thin, white, or occasionally pink, strongly veined petals may exceed two inches; and in Michigan a monstrous form has been found. The broadly rhombic leaves, tapering to a point, and lacking petioles, are seated in the usual whorl of three, at the summit of the stem, which may attain a foot and a half in height; from the center the decorative flower arises on a long peduncle. At first the entrance to the blossom is closed by the long anthers which much exceed the filaments; and hive-bees, among other insects, in collecting pollen, transfer it to older and now expanded flowers, in which the low stigmas appear between the tall separated stamens. Nectar stored in septal glands at the base invites the visitor laden with pollen from young flowers to come in contact with the three late maturing stigmas. The berry is black. From Quebec to Florida and far westward we find this tardy wake-robin in May or June.

Certainly the commonest trillium in the East, although it thrives as far westward as Ontario and Missouri, and south to Georgia, is the NODDING WAKE-ROBIN (T. cernuum), whose white or pinkish flower droops from its peduncle until it is all but hidden under the whorl of broadly rhombic, tapering leaves. The wavy margined petals, about as long as the sepals - that is to say, half an inch long or over - curve backward at maturity. According to Miss Carter, who studied the flower in the Botanical Garden at South Hadley, Mass., it is slightly proterandrous, maturing its anthers first, but with a chance of spontaneous self-pollination by the stigmas recurving to meet the shorter stamens. She saw bumblebees visiting it for nectar. In late summer an egg-shaped, pendulous red-purple berry swings from the summit. One finds the plant in bloom from April to June, according to the climate of its long range,

Perhaps the most strikingly beautiful member of the tribe is the PAINTED TRILLIUM (T. undulatum; T. erythrocarpum of Gray). At the summit of the slender stem, rising perhaps only eight inches, or maybe twice as high, this charming flower spreads its long, wavy-edged, waxy-white petals veined and striped with deep pink or wine color. The large ovate leaves, long-tapering to a point, are rounded at the base into short petioles. The rounded, three-angled, bright red, shining berry is seated in the persistent calyx. With the same range as the nodding trillium's, the painted wake-robin comes into bloom nearly a month later - in May and June - when all the birds are not only wide awake, but have finished courting, and are busily engaged in the most serious business of life.

SHOWY LADY'S SLIPPER (Cypripedium reginae; C. spectabile of Gray) Orchid family

Flowers - Usually solitary, at summit of stem, white, or the inflated white lip painted with purplish pink and white stripes; sepals rounded oval, spreading, white, not longer than the lip; petals narrower, white; the broad sac-shaped pouch open in front, 1 in. long or over. Stem: Stout, leafy, 1 to 2 ft. high. Leaves: 3 to 8 in. long, downy, elliptic, pointed, many ribbed. Preferred Habitat - Peat-bogs; rich, low, wet woods. Flowering Season - June-September. Distribution - Nova Scotia to Georgia, westward to the Mississippi. Chiefly North.

Quite different from the showy orchis, is this far more chaste showy lady's slipper which Dr. Gray has called "the most beautiful of the genus." Because the plants live in inaccessible swampy places, where only the most zealous flower lover penetrates, they have a reputation for rarity at which one who knows a dozen places to find colonies of the stately exquisites during a morning's walk, must smile with superiority. Wine appears to overflow the large white cup and trickle down its sides. Sometimes unstained, pure white chalices are found. C. album is the name by which the plant is known in England. See note after Common Daisy.

LARGE ROUND-LEAVED or GREATER GREEN ORCHIS (Habenaria orbiculata) Orchid family

Flowers - Greenish white, in a loosely set spike; the upper sepal short, rounded; side ones spreading; petals smaller, arching; the lip long, narrow, drooping, white, prolonged into a spur often 1 1/2 in. long, curved and enlarged at base; anther sacs prominent, converging. Scape: 1 to 2 ft. high. Leaves: 2, spreading flat on ground, glossy above, silvery underneath, parallel-veined, slightly longer than wide, very large, from 4 to 7 in. across. Preferred Habitat - Rich, moist woods in mountainous regions, especially near evergreens. Flowering Season - July-August. Distribution - From British Columbia to the Atlantic; eastern half of the United States southward to the Carolinas.

Wonderfully interesting structure and the comparative rarity of this orchid, rather than superficial beauty, are responsible for the thrill of pleasure one experiences at the sight of the spike of unpretentious flowers. Two great leaves, sometimes as large as dinner plates, attract the eye to where they glisten on the ground. The spur of the blossom, the nectary, "implies a welcome to a tongue two inches long, and will reward none other," says William Hamilton Gibson. "This clearly shuts out the bees, butterflies, and smaller moths. What insect, then, is here implied? The sphinx moth, one of the lesser of the group. A larger individual might sip the nectar, it is true, but its longer tongue would reach the base of the tube without effecting the slightest contact with the pollen, which is, of course, the desideratum." How the moth, in sipping the nectar, thrusts his head against the sticky buttons to which the pollen messes are attached, and, in trying to release himself, loosens them; how he flies off with these little clubs sticking to his eyes; how they automatically adjust themselves to the attitude where they will come in contact with the stigma of the next flower visited, and so cross-fertilize it, has been told in the account of the great purple-fringed orchis of similar construction. To that species the interested reader is, therefore, referred; or, better still, to the luminous description by Dr. Asa Gray.

WHITE-FRINGED ORCHIS (Habenaria blephariglottis) Orchid family

Flowers - Pure white, fragrant, borne on a spike from 3 to 6 in. long. Spur long, slender; oval sepals; smaller petals toothed; the oblong lip deeply fringed. Stem: Slender, 1 to 2 ft. high. Leaves: Lance-shaped, parallel-veined, clasping the stem; upper ones smallest. Preferred Habitat - Peat-bogs and swamps. Flowering Season - July-August. Distribution - Northeastern United States and eastern Canada to Newfoundland.

One who selfishly imagines that all the floral beauty of the earth was created for man's sole delight will wonder why a flower so exquisitely beautiful as this dainty little orchid should be hidden in inaccessible peat-bogs, where overshoes and tempers get lost with deplorable frequency, and the water-snake and bittern mock at man's intrusion of their realm by the ease with which they move away from him. Not for man, but for the bee, the moth, and the butterfly, are orchids where they are and what they are. The white-fringed orchis grows in watery places that it may more easily manufacture nectar, and protect itself from crawling pilferers; its flowers are clustered on a spike, their lips are fringed, they have been given fragrance and a snowy-white color that they may effectually advertise their sweets on whose removal by an insect benefactor that will carry pollen from flower to flower as he feeds depends their chance of producing fertile seed. It is probable the flower is white that night-flying moths may see it shine in the gloaming. From the length and slenderness of its spur it is doubtless adapted to the sphinx moth.

At the entrance to the nectary, two sticky disks stand on guard, ready to fasten themselves to the eyes of the first moth that inserts his tongue; and he finds on withdrawing his head that two pollen-masses attached to these disks have been removed with them. This plastering over of insects' eyes by the orchids might be serious business, indeed, were not the lepidoptera gifted with numerous pairs. The fragrance of many orchids, however, would be a sufficient guide even to a blind insect. With the pollen-masses sticking to his forehead, the moth enters another flower and necessarily rubs off some grains from the pollen masses, that have changed their attitude during his flight that they may be in the precise position to fertilize the viscid stigma. In almost the same way the similar Yellow-Fringed Orchis (H. ciliaris) and the great green orchids compel insects to work for them.

A larger-flowered species, the PRAIRIE WHITE-FRINGED ORCHIS (H. lepicophea), found in bloom in June and July, on moist, open ground from western New York to Minnesota and Arkansas, differs from the preceding chiefly in having larger and greenish-white flowers, the lip cleft into wedge-shaped segments deeply fringed. The hawk-moth removes on its tongue one, but not often both, of the pollinia attached to disks on either side of the entrance to the spur.

NODDING LADIES' TRESSES or TRACES (Gyrostachys cernua; Spiranthes cernua of Gray) Orchid family

Flowers - Small, white or yellowish, without a spur, fragrant, nodding or spreading in 3 rows on a cylindrical, slightly twisted spike 4 or 5 in. long. Side sepals free, the upper ones arching, and united with petals; the oblong, spreading lip crinkle-edged, and bearing minute, hairy callosities at bases Stem: 6 in. to 2 ft. tall, with several pointed, wrapping bracts. Leaves: From or near the base, linear, almost grass-like. Preferred Habitat - Low meadows, ditches, and swamps. Flowering Season - July-October. Distribution - Nova Scotia to the Gulf of Mexico, and westward to the Mississippi.

This last orchid of the season, and perhaps the commonest of its interesting tribe in the eastern United States, at least, bears flowers that, however insignificant in size, are marvelous pieces of mechanism, to which such men as Charles Darwin and Asa Gray have devoted hours of study and, these two men particularly, much correspondence.

Just as a woodpecker begins at the bottom of a tree and taps his way upward, so a bee begins at the lower and older flowers on a spike and works up to the younger ones; a fact on which this little orchid, like many another plant that arranges its b1ossoms in long racemes, depends. Let us not note for the present what happens in the older flowers, but begin our observations, with the help of a powerful lens, when the bee has alighted on the spreading lip of a newly opened blossom toward the top of the spire. As nectar is already secreted for her in its receptacle, she thrusts her tongue through the channel provided to guide it aright, and by the slight contact with the furrowed rostellum, it splits, and releases a boat-shaped disk standing vertically on its stern in the passage. Within the boat is an extremely sticky cement that hardens almost instantly on exposure to the air. The splitting of the rostellum, curiously enough, never happens without insect aid; but if a bristle or needle be passed over it ever so lightly, a stream of sticky, milky fluid exudes, hardens, and the boat-shaped disk, with pollen masses attached, may be withdrawn on the bristle just as the bee removes them with her tongue. Each pollinium consists of two leaves of pollen united for about half their length in the middle with elastic threads. As the pollinia are attached parallel to the disk, they stick parallel on the bee's tongue, yet she may fold up her proboscis under her head, if she choose, without inconvenience from the pollen masses, or without danger of loosening them. Now, having finished sucking the newly opened flowers at the top of the spike, away she flies to an older flower at the bottom of another one. Here a marvelous thing has happened. The passage which, when the flower first expanded, scarcely permitted a bristle to pass, has now widened through the automatic downward movement of the column in order to expose the stigmatic surfaces to contact with the pollen masses brought by the bee. Without the bee's help this orchid, with a host of other flowers, must disappear from the face of the earth. So very many species which have lost the power to fertilize themselves now depend absolutely on these little pollen carriers, it is safe to say that, should the bees perish, one half our flora would be exterminated with them. On the slight downward movement of the column in the ladies' tresses, then, as well as on the bee's ministrations, the fertilization of the flower absolutely depends. "If the stigma of the lowest flower has already been fully fertilized," says Darwin, "little or no pollen will be left on its dried surface; but on the next succeeding flower, of which the stigma is adhesive, large sheets of pollen will be left. Then as soon as the bee arrives near the summit of the spike she will withdraw fresh pollinia, will fly to the lower flowers on another plant, and fertilize them; and thus, as she goes her rounds and adds to her store of honey, she continually fertilizes fresh flowers and perpetuates the race of autumnal spiranthes, which will yield honey to future generations of bees."

The SLENDER LADIES' TRESSES (G. gracilis; [S. gracilis]), with a range and season of blossom similar to the preceding species, and with even smaller white, fragrant flowers, growing on one side of a twisted spike, chooses dry fields, hillsides, open woods, and sandy places - queer habitats for a member of its moisture-loving tribe. Its leaves have usually fallen by flowering time. The cluster of tuberous, spindle-shaped roots are an aid to identification.

LESSER RATTLESNAKE PLANTAIN [DWARF RATTLESNAKE-PLANTAIN] (Peramium repens; Goodyera repens of Gray) Orchid family

Flowers - Small, greenish white, the lip pocket-shaped, borne on one side of a bracted spike 5 to 10 in. high, from a fleshy, thick fibrous root. Leaves: From the base, tufted, or ascending the stem on one side for a few inches, 1/2 in. to over 1 in. long, ovate, the silvery-white veins forming a network, or leaf blotched with white. Preferred Habitat - Woods, especially under evergreens. Flowering Season - July-August. Distribution - Colorado eastward to the Atlantic, from Nova Scotia to Florida. Europe and Asia.

Tufts of these beautifully marked little leaves carpeting the ground in the shadow of the hemlocks attract the eye, rather than the spires of insignificantly small flowers. Whoever wishes to know how the bumblebee ruptures the sensitive membrane within the tiny blossom with her tongue, and draws out the pollinia that are instantly cemented to it after much the same plan employed by the ladies' tresses, must use a good lens in studying the operation. To the structural botanist the rattlesnake plantains form an interesting connecting link between orchids of d1stinct forms. In them we see a tendency to lengthen the pollen-masses into caudicles as the showy orchis, for example, has done. "Goodyera probably shows us the state of organs in a group of orchids now mostly extinct," says Darwin; "but the parents of many living descendants."

It has been said that the Indians use this plant to cure bites of the rattlesnake; that they will handle the deadly creature without fear if some of these leaves are near at hand - in fact, a good deal is said about Indians by palefaces that makes even the stolid red man smile when confronted with the white man's tales about him. An intelligent Indian student declares that none of his race will handle a rattlesnake unless its fangs have been removed; that this plant takes its name from the resemblance of its netted-veined leaves to the belly of a serpent, and not to their curative powers; and, finally, that the Southern tribes, especially so reverence the rattlesnake that, far from trying to cure its bite, they count themselves blessed to be bitten to death by one. Indeed, the rattle, a sacred symbol, has been employed in religious ceremonies of most tribes. Snakes may be revered in other lands, but only in America is the rattlesnake worshipped. Among the Moquis there still survives much of the religion of the snake-worshipping Aztecs. Bernal Diaz tells how living rattlesnakes, kept in the great temple at Mexico as sacred and petted objects, were fed with the bodies of the sacrificed. Cortes found a town called by the Spaniards Terraguea, or the city of serpents, whose walls and temples were decorated with figures of the reptiles, which the inhabitants worshiped as gods.

The DOWNY RATTLESNAKE PLANTAIN (P. pubescens), usually a taller plant than the preceding, with larger cream-white, globular-lipped flowers on both sides of its spike, and glandular-hairy throughout, has even more strongly marked leaves. These, the most conspicuous parts, are dark grayish green, heavily netted with greenish or silvery-white veins, silky to the touch, and often wavy edged. This plant scarcely strays westward beyond the Mississippi, but it is common East. It also blooms in midsummer, and shows a preference for dry woods where oak and pine abound.

LIZARD'S TAIL [LIZARD'S-TAIL, WATER-DRAGON] (Saurus cernuus) Lizard's-tail family

Flowers - Fragrant, very small, white, lacking a perianth, bracted, densely crowded on peduncled, slender spikes 4 to 6 in. long and nodding at the tip. Stamens 6 to 8, the filaments white; carpels 3 or 4, united at base, dangling. Stem: 2 to 5 ft. high, jointed, sparingly branched, leafy. Leaves: Heart-shaped, palmately ribbed, dark green, thin, on stout petioles. Preferred Habitat - Swamps, shallow water. Flowering Season - June-August. Distribution - Southern New England to the Gulf, westward to Minnesota and Texas.

The fragrance arising from these curious, drooping, tail-like spikes of flowers, where they grow in numbers, must lure their insect friends as it does us, since no showy petals or sepals advertise their presence. Nevertheless they are what are known as perfect flowers, each possessing stamens and pistils, the only truly essential parts, however desirable a gaily colored perianth may be to blossoms attempting to woo such large land insects as the bumblebee and butterfly. Since flies, whose color sense is by no means so acute as their sense of smell, are by far the most abundant fertilizers of waterside plants, we can see a tendency in such to suppress their petals, for the flowers to become minute and massed in series that the little visitors may more readily transfer pollen from one to another, and to become fragrant - just what the lizard's tail has done.

SPRING BEAUTY; CLAYTONIA (Claytonia Virginica) Purslane family.

Flowers - White veined with pink, or all pink, the veinings of deeper shade, on curving, slender pedicels, several borne in a terminal loose raceme, the flowers mostly turned one way (secund). Calyx of 2 ovate sepals; corolla of 5 petals slightly united by their bases; 5 stamens, 1 inserted on base of each petal; the style 3-cleft. Stem: Weak, 6 to 12 in. long, from a deep, tuberous root. Leaves: Opposite above, linear to lance-shaped, shorter than basal ones, which are 3 to 7 in. long; breadth variable. Preferred Habitat - Moist woods, open groves, low meadows. Flowering Season - March-May. Distribution - Nova Scotia and far westward, south to Georgia and Texas.

Dainty clusters of these delicate, starry blossoms, mostly turned in one direction, expand in the sunshine only, like their gaudy cousin the portulaca and the insignificant little yellow flowers of another relative, the ubiquitous, invincible "pussley" immortalized in "My Summer in a Garden." At night and during cloudy, stormy weather, when their benefactors are not flying, the claytonias economically close their petals to protect nectar and pollen from rain and pilferers. Pick them, the whole plant droops, and the blossoms close with indignation; nor will any coaxing but a combination of hot water and sunshine induce them to open again. Theirs is a long beauty sleep. They are supersensitive exquisites, however hardy.

Very early in the spring a race is run with the hepatica, arbutus, adder's tongue, blood-root, squirrel corn, and anemone for the honor of being the earliest wild flower; and although John Burroughs and Dr. Abbott have had the exceptional experience of finding the claytonia even before the hepatica - certainly the earliest spring blossom worthy the name in the Middle and New England States - of course the rank skunk-cabbage, whose name is snobbishly excluded from the list of fair competitors, has quietly opened dozens of minute florets in its incurved horn before the others have even started.

Whether the petals of the spring beauty are white or pink, they are always exquisitely marked with pink lines converging near the base and ending in a yellow blotch to serve as pathfinders for the female bumblebees and the little brown bombylius, among other pollen carriers. A newly opened flower, with its stamens surrounding the pistil, must be in peril of self-fertilization one would think who did not notice that when the pollen is in condition for removal by the bees and flies, the stigmatic surfaces of the three-cleft style are tightly pressed together that not a grain may touch them. But when the anthers have shed their pollen, and the filaments have spread outward and away from the pistil, the three stigmatic arms branch out to receive the fertilizing dust carried from younger flowers by their busy friends.

STARRY CAMPION (Silene stellata) Pink family

Flowers - White, about 1/2 in. broad or over, loosely clustered in a showy, pyramidal panicle. Calyx bell-shaped, swollen, 5-toothed, sticky; 5 fringed and clawed petals; 10 long, exserted stamens; 3 styles. Stem: Erect, leafy, 2 to 3 1/2 ft. tall, rough-hairy. Leaves: Oval, tapering to a point, 2 to 4 in. long, seated in whorls of 4 around stem, or loose ones opposite. Preferred Habitat - Woods, shady banks. Flowering Season - June-August. Distribution - Rhode Island westward to Mississippi, south to the Carolinas and Arkansas.

Feathery white panicles of the starry campion, whose protruding stamens and fringed petals give it a certain fleeciness, are dainty enough for spring; by midsummer we expect plants of ranker growth and more gaudy flowers. To save the nectar in each deep tube for the moths and butterflies which cross-fertilize all this tribe of night and day blossoms, most of them - and the campions are notorious examples - spread their calices, and some their pedicels as well, with a sticky substance to entrap little crawling pilferers. Although a popular name for the genus is catchfly, it is usually the ant that is glued to the viscid parts, for the fly that moves through the air alights directly on the flower it is too short-lipped to suck. An ant catching its feet on the miniature lime-twig, at first raises one foot after another and draws it through its mouth, hoping to rid it of the sticky stuff, but only with the result of gluing up its head and other parts of the body. In ten minutes all the pathetic struggles are ended. Let no one guilty of torturing flies to death on sticky paper condemn the Silenes!

The BLADDER CAMPION (S. vulgaris; S. inflata of Gray) to be recognized by its much inflated calyx, especially round in fruit, the two-cleft white petals; and its opposite leaves that are spatulate at the base of the plant, is a European immigrant now naturalized and locally very common from Illinois eastward to New Jersey and north to New Brunswick. Like the night-flowering catchfly this blossom has adapted itself to the night-flying moths; but when either remains open in the morning, bumblebees gladly take the leavings in the deep cup. To insure cross-fertilization, some of the bladder-campion flowers have stamens only, some have a pistil only; some have both organs maturing at different times. In all the night-flowering Silene, each flower, unless unusually disturbed, lasts three days and three nights. Late in the afternoon of the first day, when the petals begin to expand, the five stamens opposite the sepals lengthen in about two hours, and by sunset the anthers, which have matured at the same time, are covered with pollen. So they remain until the forenoon of the second day, and then the emptied anthers hang like shriveled bags, or drop off altogether. Late in the second afternoon, the second set of stamens repeat the actions of their predecessors, bend backward and shed their anthers the following, that is to say the third, morning. But on the third afternoon up rise the S-shaped, twisted stigmas, which until now had been hidden in the center of the flower. Moths, therefore, must transfer pollen from younger to older blossoms.

"With this lengthening and bending of the stamens and stigmas," says Dr. Kerner, "goes hand in hand the opening and shutting of the corolla. With the approach of dusk, the bifid limbs of the petals spread out in a flat surface and fall back against the calyx. In this position they remain through the night, and not till the following morning do they begin (more quickly in sunshine and with a mild temperature, more slowly with a cloudy sky and in cold, wet weather) to curl themselves up in an in-curved spire, while at the same time they form longitudinal creases, and look as though they were gathered in, or wrinkled;…but no sooner does evening return than the wrinkles disappear, the petals become smooth, uncurl themselves, and fall back upon the calyx, and the corolla is again expanded."

Curiously enough, these flowers, which by day we should certainly say were not fragrant, give forth a strong perfume at evening the better to guide moths to their feast. From eight in the evening until three in the morning the fragrance is especially strong. The white blossoms, so conspicuous at night, have little attraction for color-loving butterflies and bees by day; then, as there is no pollen to be carried from the shriveled anther sacs, no visitor is welcome, and the petals close to protect the nectar for the flower's true benefactors. Indeed, few flowers show more thorough adaptation to the night-flying moths than these Silene.

POKEWEED; SCOKE; PIGEON-BERRY; INK-BERRY; GARGET (Phytolacca decandra) Pokeweed family

Flowers - White, with a green centre, pink-tinted outside, about 1/4 in. across, in bracted racemes 2 to 8 in. long. Calyx of 4 or 5 rounded persistent sepals, simulating petals; no corolla; 10 short stamens; 10-celled ovary, green, conspicuous; styles curved. Stem: Stout, pithy, erect, branching, reddening toward the end of summer, 4 to 10 ft. tall, from a large, perennial, poisonous root. Leaves: Alternate, petioled, oblong to lance-shaped, tapering at both ends, 8 to 12 in. long. Fruit: Very juicy, dark purplish berries, hanging in long clusters from reddened footstalks; ripe, August-October. Preferred Habitat - Roadsides, thickets, field borders, and waste soil, especially in burnt-over districts. Flowering Season - June-October. Distribution - Maine and Ontario to Florida and Texas.

When the pokeweed is "all on fire with ripeness," as Thoreau said; when the stout, vigorous stem (which he coveted for a cane), the large leaves, and even the footstalks, take on splendid tints of crimson lake, and the dark berries hang heavy with juice in the thickets, then the birds, with increased, hungry families, gather in flocks as a preliminary step to traveling southward. Has the brilliant, strong-scented plant no ulterior motive in thus attracting their attention at this particular time? Surely! Robins, flickers, and downy woodpeckers, chewinks and rose-breasted grosbeaks, among other feathered agents, may be detected in the act of gormandizing on the fruit, whose undigested seeds they will disperse far and wide. Their droppings form the best of fertilizers for young seedlings; therefore the plants which depend on birds to distribute seeds, as most berry bearers do, send their children abroad to found new colonies, well equipped for a vigorous start in life. What a hideous mockery to continue to call this fruit the pigeon-berry, when the exquisite bird whose favorite food it once was, has been annihilated from this land of liberty by the fowler's net! And yet flocks of wild pigeons, containing not thousands but millions of birds, nested here even thirty years ago. When the market became glutted with them, they were fed to hogs in the West!

Children, and some grown-ups, find the deep magenta juice of the ink-berry useful. Notwithstanding the poisonous properties of the root, in some sections the young shoots are boiled and eaten like asparagus, evidently with no disastrous consequences. For any service this plant may render to man and bird, they are under special obligation to the little Halictus bees, but to other short-tongued bees and flies as well. These small visitors, flying from such of the flowers as mature their anthers first, carry pollen to those in the female, or pistillate, stage. Exposed nectar rewards their involuntary kindness. In stormy weather, when no benefactors can fly, the flowers are adapted to fertilize themselves through the curving of the styles.

COMMON CHICKWEED (Aisine media; Stellaria media of Gray) Pink family

Flowers - Small, white, on slender pedicels from leaf axils, also in terminal clusters. Calyx (usually) of 5 sepals, much longer than the 5 (usually) 2-parted petals; 2-10 stamens; 3 or 4 styles. Stem: Weak, branched, tufted, leafy, 4 to 6 in long, a hairy fringe on one side. Leaves: Opposite, acutely oval, lower ones petioled, upper ones seated on stem. Preferred Habitat - Moist, shady soil; woods; meadows. Flowering Season - Throughout the year. Distribution - Almost universal.

The sole use man has discovered for this often pestiferous weed with which nature carpets moist soil the world around is to feed caged song-birds. What is the secret of the insignificant little plant's triumphal progress? Like most immigrants that have undergone ages of selective struggle in the Old World, it successfully competes with our native blossoms by readily adjusting itself to new conditions, filling places unoccupied, and chiefly by prolonging its season of bloom beyond theirs, to get relief from the pressure of competition for insect trade in the busy season. Except during the most cruel frosts, there is scarcely a day in the year when we may not find the little star-like chickweed flowers. Contrast this season with that of a native chickweed, the LONG-LEAVED STITCHWORT [LONG-LEAVED CHICKWEED] (A. longifolia [S. longifolia]), blooming only from May till July, when competition is fiercest! Also, the common chickweed has its parts so arranged that it can fertilize itself when it is too cold for insect pollen-carriers to fly; then, especially, are many of its stamens abortive, not to waste the precious dust. Yet even in winter it produces abundant seed. In sunny, fine spring weather, however, when so much nectar is secreted the fine little drops may be easily seen by the naked eye, small bees, flies, and even thrips visit the blossoms whose anthers shed pollen one by one before the three stigmatic surfaces are ready to receive any from younger flowers.

SWEET-SCENTED WHITE WATER LILY; POND LILY; WATER NYMPH; WATER CABBAGE [FRAGRANT WATER-LILY] (Castalia odorata; Nymphaea odorata of Gray) Water-lily family

Flowers - Pure white or pink tinged, rarely deep pink, solitary, 3 to 8 in. across, deliciously fragrant, floating. Calyx of 4 sepals, green outside; petals of indefinite number, overlapping in many rows, and gradually passing into an indefinite number of stamens; outer row of stamens with petaloid filaments and short anthers, the inner yellow stamens with slender filaments and elongated anthers; carpels of indefinite number, united into a compound pistil, with spreading and projecting stigmas. Leaves: Floating, nearly round, slit at bottom, shining green above, reddish and more or less hairy below, 4 to 12 in. across, attached to petiole at center of lower surface. Petioles and peduncles round and rubber-like, with 4 main air-channels. Rootstock: (Not true stem), thick, simple or with few branches, very long. Preferred Habitat - Still water, ponds, lakes, slow streams. Flowering Season - June-September. Distribution - Nova Scotia to Gulf of Mexico, and westward to the Mississippi.

Sumptuous queen of our native aquatic plants, of the royal family to which the gigantic Victoria regia of Brazil belongs, and all the lovely rose, lavender, blue, and golden exotic water lilies in the fountains of our city parks, to her man, beast, and insect pay grateful homage. In Egypt, India, China, Japan, Persia, and Asiatic Russia, how many millions have bent their heads in adoration of her relative the sacred lotus! From its center Brahma came forth; Buddha, too, whose symbol is the lotus, first appeared floating on the mystic flower (Nelumbo nelumbo, formerly Nelumbium speciosum). Happily the lovely pink or white "sacred bean" or "rose-lily" of the Nile, often cultivated here, has been successfully naturalized in ponds about Bordentown, New Jersey, and maybe elsewhere. If he who planteth a tree is greater than he who taketh a city, that man should be canonized who introduces the magnificent wild flowers of foreign lands to our area of Nature's garden.

Now, cultivation of our native water lilies and all their hardy kin, like charity, begins at home. Their culture in tubs, casks, or fountains on the lawn, is so very simple a matter, and the flowers bloom so freely, every garden should have a corner for aquatic plants. Secure the water-lily roots as early in the spring as possible, and barely cover them with good rich loam or muck spread over the bottom of the sunken tub to a depth of six or eight inches. After it has been filled with water, and replenished from time to time to make good the loss by evaporation, the water garden needs no attention until autumn. Then the tub should be drained, and removed to a cellar, or it may be covered over with a thick mattress of dry leaves to protect from hard freezing. In their natural haunts, water lilies sink to the bottom, where the water is warmest in winter. Possibly the seed is ripened below the surface for the same reason. At no time should the crown of the cultivated plant be lower than two feet below the water. If a number of species are grown, it is best to plant each kind in a separate basket, sunk in the shallow tub, to prevent the roots from growing together, as well as to obtain more effective decoration. Charming results may be obtained with small outlay of either money or time. Nothing brings more birds about the house than one of these water gardens; that serves at once as drinking fountain and bath to our not over-squeamish feathered neighbors. The number of insects these destroy, not to mention the joy of their presence, would alone compensate the householder of economic bent for the cost of a shallow concrete tank.

Opening some time after six o'clock in the morning, the white water lily spreads its many-petalled, deliciously fragrant, golden-centered chalice to welcome the late-flying bees and flower flies, the chief pollinators. Beetles, "skippers," and many other creatures on wings alight too. "I have named two species of bees (Halictus nelumbonis and Prosopis nelumbonis) on account of their close economic relation to these flowers," says Professor Robertson, who has captured over two hundred and fifty species of bees near his home in Carlinville, Illinois, and described nearly a third of them as new. Linnaeus, no doubt the first to conceive the pretty idea of making a floral clock, drew up a list of blossoms whose times of opening and closing marked the hours on its face; but even Linnaeus failed to understand that the flight of insects is the mainspring on which flowers depend to set the mechanism going. In spite of its whiteness and fragrance, the water lily requires no help from night-flying insects in getting its pollen transferred; therefore, when the bees and flies rest from their labors at sundown, it may close the blinds of its shop, business being ended for the day.

"When doctors disagree, who shall decide?" It is contended by one group of scientists that the water lily, which shows the plainest metamorphosis of some sort, has developed its stamens from petals - just the reverse of Nature's method, other botanists claim. A perfect flower, we know, may consist of only a stamen and a pistil, the essential organs, all other parts being desirable, but of only secondary importance. Gardeners, taking advantage of a wild flower's natural tendency to develop petals from stamens and to become "double," are able to produce the magnificent roses and chrysanthemums of today; and so it would seem that the water lily, which may be either self-fertilized or cross-fertilized by pollen-carriers in its present state of development, is looking to a more ideal condition by increasing its attractiveness to insects as it increases the number of its petals, and by economizing pollen in transforming some of the superfluous stamens into petals.

Scientific speculation, incited by the very fumes of the student lamp, may weary us in winter, but just as surely is it dispelled by the fragrance of the lilies in June. Then, floating about in a birch canoe among the lily-pads, while one envies the very moose and deer that may feed on fare so dainty and spend their lives amid scenes of such exquisite beauty, one lets thought also float as idly as the little clouds high overhead.

LAUREL or SMALL MAGNOLIA; SWEET or WHITE BAY; SWAMP LAUREL or SASSAFRAS; BEAVER-TREE [SWEETBAY MAGNOLIA] (Magnolia Virginiana; M. glauca of Gray) Magnolia family

Flowers - White, 2 to 3 in. across, globular, depressed, deliciously fragrant, solitary at ends of branches. Calyx of 3 petal-like, spreading sepals. Corolla of 6 to 12 concave rounded petals in rows; stamens very numerous, short, with long anthers; carpels also numerous, and borne on the thick, green, elongated receptacle. Trunk: 4 to 70 ft. high. Leaves: Enfolded in the bud by stipules that fall later and leave rings around gradually lengthening branch; the leaves 3 to 6 in. long in maturity, broadly oblong, thick, almost evergreen, dark above, pale beneath, on short petioles. Fruit: An oblong, reddish pink cone, fleshy, from which the scarlet seeds hang by slender threads. Preferred Habitat - Swampy woods and open swamps. Flowering Season - May-June. Distribution - Atlantic States from Massachusetts southward, and Gulf States from Florida to Texas.

"Every flower its own bo-quet!" shouted by a New York street vender of the lovely magnolia blossoms he had just gathered from the Jersey swamps, emphasized only one of the many claims they have upon popular attention. Far and wide the handsome shrub, which frequently attains a tree's height, is exported from its native hiding-places to adorn men's gardens, and there, where a better opportunity to know it at all seasons is granted, one cannot tell which to admire most, the dark, bluish-green leathery leaves, silvery beneath; the cream-white, deliciously fragrant blossoms that turn pale apricot with age; or the brilliant fruiting cone with the scarlet seeds a-dangling. At all seasons it is a delight. When most members of this lovely tribe confine themselves to warm latitudes, we especially prize the species that naturally endures the rigorous climate of the "stern New England coast."

Beavers (when they used to be common in the East) so often made use of the laurel magnolia, not only of the roots for food, but of the trunk, whose bitter bark, white sapwood, and soft, reddish-brown heartwood were gnawed in constructing their huts, that in some sections it is still known as the beaver-tree. According to Delpino, the conspicuous, pollen-laden magnolia flowers, with their easily accessible nectar, attract beetles chiefly. These winged messengers, entering the heart of a newly opened blossom, find shelter beneath the inner petals that form a vault above their heads, and warmth that may be felt by the finger, and abundant food; consequently they remain long in an asylum so delightful, or until the expanding petals turn them out to carry the pollen, with which they have been thoroughly dusted during their hospitable entertainment, to younger flowers. As the blossoms mature their stigmas in the first stage and the anthers in the second, it follows the beetles must regularly cross-fertilize them as they fly from one shelter to another.

GOLD-THREAD; CANKER-ROOT [GOLDTHREAD] (Coptis trifolia) Crowfoot family [Buttercup family]

Flowers - Small white, solitary, on a slender scape 3 to 6 in. high. Sepals 5 to 7, petal-like, falling early; petals 5 or 6, inconspicuous, like club-shaped columns; stamens numerous carpels few, the stigmatic surfaces curved. Leaves: From the base, long petioled, divided into 3 somewhat fan-shaped, shining, evergreen, sharply toothed leaflets. Rootstock: Thread-like, long, bright yellow, wiry, bitter. Preferred Habitat - Cool mossy bogs, damp woods. Flowering Season - May-August Distribution - Maryland and Minnesota northward to circumpolar regions.

The shining, evergreen, thrice-parted leaves with which this charming little plant carpets its retreats form the best of backgrounds to set off the fragile, tiny white flowers that look like small wood anemones. Why does the gold-thread choose to dwell where bees and butterflies, most flowers' best friends, rarely penetrate? Doubtless because the cool, damp habitat that develops abundant fungi also perfectly suits the fungus gnats and certain fungus-feeding beetles that are its principal benefactors. "The entire flower is constructed with reference to their visits," says Mr. Clarence Moores Weed; "the showy sepals attract their attention; the abnormal petals furnish them food; the many small stamens with white anthers and white pollen furnish a surface to walk upon, and a foreground in which the yellow nectar-cups are distinctly visible; the long-spreading recurved stigmas cover so large a portion of the blossom that it would be difficult even for one of the tiny visitors to take many steps without contact with one of them." On a sunny June day the lens usually reveals at least one tiny gnat making his way from one club-shaped petal to another - for the insignificant petals are mere nectaries - and transferring pollen from flower to flower.

Dig up a plant, and the fine tangled, yellow roots tell why it was given its name. In the good old days when decoctions of any herb that was particularly nauseous were swallowed in the simple faith that virtue resided in them in proportion to their revolting taste, the gold-thread's bitter roots furnished a tea much valued as a spring tonic and as a cure for ulcerated throats and canker-sore mouths of helpless children.

WHITE BANEBERRY (Actaea alba) Crowfoot family

Flowers - Small, white, in a terminal oblong raceme. Calyx of 3 to 5 petal-like, early-falling sepals; petals very small, 4 to 10, spatulate, clawed; stamens white, numerous, longer than petals; 1 pistil with a broad stigma. Stem: Erect, bushy, to 2 ft. high. Leaves: Twice or thrice compounded of sharply toothed and pointed, sometimes lobed, leaflets, petioled. Fruit: Clusters of poisonous oval white berries with dark purple spot on end, formed from the pistils. Both pedicels and peduncles much thickened and often red after fruiting. Preferred Habitat - Cool, shady, moist woods. Flowering Season - April-June. Distribution - Nova Scotia to Georgia and far West.

However insignificant the short fuzzy clusters of flowers lifted by this bushy little plant, we cannot fail to name it after it has set those curious white berries with a dark spot on the end, which Mrs. Starr Dana graphically compares to "the china eyes that small children occasionally manage to gouge from their dolls' heads." For generations they have been called "doll's eyes" in Massachusetts. Especially after these poisonous berries fully ripen and the rigid stems which bear them thicken and redden, we cannot fail to notice them. As the sepals fall early, the white stamens and stigmas are the most conspicuous parts of the flowers. A cluster opening its blossoms almost simultaneously, the plant's only hope of cross-fertilization lies in the expectation that the small female bees (Halictus) which come for pollen - no nectar being secreted - will leave some brought from another flower on the stigma as they enter, and before collecting a fresh supply. The time elapsing between the maturity of the stigmas and the anthers is barely perceptible; nevertheless there is a tendency toward the former maturing first.

The RED BANEBERRY, COHOSH, or HERB-CHRISTOPHER (A. rubra; A. spicata, var. rubra of Gray) - a more common species northward, although with a range, habit, and aspect similar to the preceding, may be known by its more ovoid raceme of feathery white flowers, its less sharply pointed leaves, and, above all, by its rigid clusters of oval red berries on slender pedicels, so conspicuous in the woods of late summer.

BLACK COHOSH; BLACK SNAKEROOT; TALL BUGBANE (Cimicifuga racemosa) Crowfoot family [Buttercup family]

Flowers - Fetid, feathery, white, in an elongated wand-like raceme, 6 in. to 2 ft. long, at the end of a stem 3 to 8 ft. high. Sepals petal-like, falling early; 4 to 8 small stamen-like petals 2-cleft; stamens very numerous, with long filaments; 1 or 2 sessile pistils with broad stigmas. Leaves: Alternate, on long petioles, thrice compounded of oblong, deeply toothed or cleft leaflets, the end leaflet often again compound. Fruit: Dry oval pods, their seeds in 2 rows. Preferred Habitat - Rich woods and woodland borders, hillsides. Flowering Season - June-August. Distribution - Maine to Georgia, and westward from Ontario to Missouri.

Tall white rockets, shooting upward from a mass of large handsome leaves in some heavily shaded midsummer woodland border, cannot fail to impress themselves through more than one sense, for their odor is as disagreeable as the fleecy white blossoms are striking. Obviously such flowers would be most attractive to the carrion and meat flies. Cimicifuga, meaning to drive away bugs, and the old folk-name of bugbane testify to a degree of offensiveness to other insects, where the flies' enjoyment begins. As these are the only insects one is likely to see about the fleecy wands, doubtless they are their benefactors. The countless stamens which feed them generously with pollen willingly left for them alone must also dust them well as they crawl about before flying to another fetid lunch.

The close kinship with the baneberries is detected at once on examining one of these flowers. Were the vigorous plant less offensive to the nostrils, many a garden would be proud to own so decorative an addition to the shrubbery border.

WOOD ANEMONE; WIND FLOWER (Anemone quinquefolia) Crowfoot family

Flowers - Solitary, about 1 in. broad, white or delicately tinted with blue or pink outside. Calyx of 4 to 9 oval, petal-like sepals; no petals; stamens and carpels numerous, of indefinite number. Stem: Slender, 4 to 9 in. high, from horizontal elongated rootstock. Leaves: On slender petioles, in a whorl of 3 to 5 below the flower, each leaf divided into 3 to 5 variously cut and lobed parts; also a late-appearing leaf from the base. Preferred Habitat - Woodlands, hillsides, light soil, partial shade. Flowering Season - April-June. Distribution - Canada and United States, south to Georgia, west to Rocky Mountains.

According to one poetical Greek tradition, Anemos, the wind, employs these exquisitely delicate little star-like namesakes as heralds of his coming in early spring, while woods and hillsides still lack foliage to break his gust's rude force. Pliny declared that only the wind could open anemones! Another legend utilized by countless poets pictures Venus wandering through the forests grief-stricken over the death of her youthful lover.

"Alas, the Paphian! fair Adonis slain! Tears plenteous as his blood she pours amain; But gentle flowers are born and bloom around From every drop that falls upon the ground: Where streams his blood, there blushing springs the rose; And where a tear has dropped, a wind-flower blows."

Indeed, in reading the poets ancient and modern for references to this favorite blossom, one realizes as never before the significance of an anthology, literally a flower gathering.

But it is chiefly the European anemone that is extolled by the poets. Nevertheless our more slender, fragile, paler-leaved, and smaller-flowered species, known, strange to say, by the same scientific name, possesses the greater charm. Doctors, with more prosaic eyes than the poets, find acrid and dangerous juices in the anemone and its kin. Certain European peasants will run past a colony of these pure innocent blossoms in the belief that the very air is tainted by them. Yet the Romans ceremonially picked the first anemone of the year, with an incantation supposed to guard them against fever. The identical plant that blooms in our woods, which may be found also in Asia, is planted on graves by the Chinese, who call it the "death flower."

To leave legend and folk lore, the practical scientist sees in the anemone, trembling and bending before the wind, a perfect adaptation to its environment. Anchored in the light soil by a horizontal rootstock; furnished with a stem so slender and pliable no blast can break it; its pretty leaves whorled where they form a background to set off the fragile beauty of the solitary flower above them; a corolla economically dispensed with, since the white sepals are made to do the advertising for insects; the slightly nodding attitude of the blossom in cloudy weather, that the stigmas may be in the line of the fall of pollen jarred out by the wind in case visitors seeking pollen fail to bring any from other anemones - all these features teach that every plant is what it is for excellent reasons of its own; that it is a sentient being, not to be admired for superficial beauty merely, but also for those same traits which operate in the human race, making it the most interesting of studies.

Note the clusters of tuberous dahlia-like roots, the whorl of thin three-lobed rounded leaflets on long, fine petioles immediately below the smaller pure white or pinkish flowers usually growing in loose clusters, to distinguish the more common RUE-ANEMONE (Syndesmon thalictroides - Thalictrum anemonoides of Gray) from its cousin the solitary flowered wood or true anemone. Generally there are three blossoms of the rue-anemone to a cluster, the central one opening first, the side ones only after it has developed its stamens and pistils to prolong the season of bloom and encourage cross-pollination by insects. In the eastern half of the United States, and less abundantly in Canada, these are among the most familiar spring wild flowers. Pick them and they soon wilt miserably; lift the plants early, with a good ball of soil about the roots, and they will unfold their fragile blossoms indoors, bringing with them something of the unspeakable charm of their native woods and hillsides just waking into life.

The TALL or SUMMER ANEMONE (A. Virginiana), called also THIMBLE-WEED from its oblong, thimble-like fruit-head, bears solitary, inconspicuous greenish or white flowers, often over an inch across, and generally with five rounded sepals, on erect, long stalks from June to August. Contrasted with the dainty tremulous little spring anemones, it is a rather coarse, stiff, hairy plant two or three feet tall. Its preference is for woodlands, whereas another summer bloomer, the LONG-FRUITED ANEMONE (A. cylindrica), a smaller, silky-hairy plant often confused with it, chooses open places, fields, and roadsides. The leaves of the thimble-weed, which are set in a whorl high up on the stem, and also spring from the root, after the true anemone fashion, are long petioled, three-parted, the divisions variously cut, lobed, and saw-edged. The flower-stalks which spring from this whorl continue to rise throughout the summer. The first, or middle of these peduncles, lacks leaves; later ones bear two leaves in the middle, from which more flower-stalks arise, and so on.

VIRGIN'S BOWER; VIRGINIA CLEMATIS; TRAVELLER'S JOY; OLD MAN'S BEARD (Clematis Virginiana) Crowfoot family

Flowers - White and greenish, about 1 in. across or less, in loose clusters from the axils. Calyx of 4 or 5 petal-like sepals; no petals; stamens and pistils numerous, of indefinite number; the staminate and pistillate flowers on separate plants; the styles feathery, and over 1 in. long in fruit. Stem: Climbing, slightly woody. Leaves: Opposite, slender petioled, divided into 3 pointed and widely toothed or lobed leaflets. Preferred Habitat - Climbing over woodland borders, thickets, roadside shrubbery, fences, and walls; rich, moist soil. Flowering Season - July-September. Distribution - Georgia and Kansas northward less common beyond the Canadian border.

Fleecy white clusters of wild clematis, festooning woodland and roadside thickets, vary so much in size and attractiveness that one cannot but investigate the reason. Examination shows that comparatively few of the flowers are perfect, that is, few contain both stamens and pistils; the great majority are either male - the more showy ones - or female - the ones so conspicuous in fruit - and, like Quakers in meeting, the sexes are divided. The plant that bears staminate blossoms produces none that are pistillate, and vice versa - another marvelous protection against that horror of the floral race, self-fertilization, and a case of absolute dependence on insect help to perpetuate the race. Since the clematis blooms while insect life is at its height, and after most, if not all, of the Ranunculaceae have withdrawn from the competition for trade; moreover, since its white color, so conspicuous in shady retreats, and its accessible nectar attract hosts of flies and the small, short-tongued bees chiefly, that are compelled to work for it by transferring pollen while they feed, it goes without saying that the vine is a winner in life's race.

Charles Darwin, who made so many interesting studies of the power of movement in various plants, devoted special attention to the clematis clan, of which about one hundred species exist but, alas! none to our traveller's joy, that flings out the right hand of good fellowship to every twig within reach, winds about the sapling in brotherly embrace, drapes a festoon of flowers from shrub to shrub, hooks even its sensitive leafstalks over any available support as it clambers and riots on its lovely way. By rubbing the footstalk of a young leaf with a twig a few times on any side, Darwin found a clematis leaf would bend to that side in the course of a few hours, but return to the straight again if nothing remained on which to hook itself. "To show how sensitive the young petioles are," he wrote, "I may mention that I just touched the undersides of two with a little watercolor which, when dry, formed an excessively thin and minute crust but this sufficed in twenty-four hours to cause both to bend downwards."

In early autumn, when the long, silvery, decorative plumes attached to a ball of seeds form feathery, hoary masses even more fascinating than the flower clusters, the name of old man's beard is most suggestive. These seeds never open, but, when ripe, each is borne on the autumn gales, to sink into the first moist, springy resting place.

The English counterpart of our virgin's bower is fragrant.

TALL MEADOW-RUE (Thalictrum polyganum; T. Cornuti of Gray) Crowfoot family

Flowers - Greenish white, the calyx of 4 or 5 sepals, falling early; no petals; numerous white, thread-like, green-tipped stamens, spreading in feathery tufts, borne in large, loose, compound terminal clusters 1 ft. long or more. Stem: Stout, erect, 3 to 11 ft. high, leafy, branching above. Leaves: Arranged in threes, compounded of various shaped leaflets, the lobes pointed or rounded, dark above, paler below. Preferred Habitat- Open sunny swamps, beside sluggish water, low meadows. Flowering Season - July-September. Distribution - Quebec to Florida, westward to Ohio.

Masses of these soft, feathery flowers, towering above the ranker growth of midsummer, possess an unseasonable, ethereal, chaste, spring-like beauty. On some plants the flowers are white and exquisite; others, again, are dull and coarser. Why is this? Because these are what botanists term polygamous flowers, i.e., some of them are perfect, containing both stamens and pistils; some are male only others, again, are female. Naturally an insect, like ourselves, is first attracted to the more beautiful male blossoms, the pollen bearers, and of course it transfers the vitalizing dust to the dull pistillate flowers visited later. But the meadow-rue, which produces a superabundance of very light, dry pollen, easily blown by the wind, is often fertilized through that agent also, just as grasses, plantains, sedges, birches, oaks, pines, and all cone-bearing trees are. As might be expected, a plant which has not yet ascended the evolutionary scale high enough to economize its pollen by making insects carry it invariably, overtops surrounding vegetation to take advantage of every breeze that blows.

The EARLY MEADOW-RUE (T. dioicum), found blooming in open, rocky woods during April and May, from Alabama northward to Labrador, and westward to Missouri, grows only one or two feet high, and, like its tall sister, bears fleecy, greenish-white flowers, the staminate and the pistillate ones on different plants. These produce no nectar; they offer no showy corolla advertisement to catch the eye of passing insects; yet so abundant is the dry pollen produced by the male blossoms that insects which come to feed on it must occasionally transfer some, albeit this primitive genus still depends largely on the wind. Not its flower, but the exquisite foliage resembling sprays of a robust maidenhair fern, is this meadow-rue's chief charm.

The PURPLISH MEADOW-RUE (T. purpurascens), so like the tall species in general characteristics that one cannot tell the dried and pressed specimens of these variable plants apart, is easily named afield by the purplish tinge of its green polygamous flowers. Often its stems show color also. Sometimes, not always, the plant is downy, and the comparatively thick leaflets, which are dark green above, are waxy beneath. We look for this meadow-rue in copses and woodlands from Northern Canada to Florida, and far westward after the early meadow-rue has flowered, but before the tall one spreads its fleecy panicles. Quite as decorative as the flower clusters are the compound seed-bearing stars.

TWIN-LEAF; RHEUMATISM ROOT (Jeffersonia diphylla) Barberry family

Flowers - White, 1 in. broad, solitary, on a naked scape about 7 in. high in flower, more than twice as tall in fruit. Calyx of 4 petal-like sepals falling early; 8 longer, flat, oblong petals; 8 stamens; 1 pistil. Leaves: From the root, long-petioled, rounded, palmately veined, cleft into 2 divisions. Fruit: A leathery, many-seeded capsule, slit horizontally. Preferred habitat - Rich shady woods. Flowering Season - April-May. Distribution - New York to Virginia, west to Ontario and Tennessee.

Like many little darkies in the United States, this low plant was named for Thomas Jefferson. One suspects from a glance at its solitary white flower and deeply divided leaves that it is not far removed from the May apple, which is characterized by even greater Jeffersonian simplicity of habit, although separated into another genus.

MAY APPLE; HOG APPLE; MANDRAKE; WILD LEMON (Podophyllum peltatum) Barberry family

Flowers - White, solitary, large, unpleasantly scented, nodding from the fork between a pair of terminal leaves. Calyx of 6 short-lived sepals; 6 to 9 rounded, flat petals stamens as many as petals or (usually) twice as many; 1 pistil, with a thick stigma. Stem: 1 to 1 1/2 ft. high, from a long, running rootstock. Leaves: Of flowerless stems (from separate root-stock), solitary, on a long petiole from base, nearly 1 ft. across, rounded, centrally peltate, umbrella fashion, 5 to 7 lobed, the lobes 2-cleft, dark above, light green below. Leaves of flowering stem 1 to 3, usually a pair, similar to others, but smaller. Fruit: A fleshy, yellowish, egg-shaped, many-seeded fruit about 2 in. long. Preferred habitat - Rich, moist woods. Flowering Season - May. Distribution - Quebec to the Gulf of Mexico, westward to Minnesota and Texas.

In giving this plant its abridged scientific name, Linnaeus seemed to see in its leaves a resemblance to a duck's foot (Anapodophyllum) but equally imaginative American children call them green umbrellas, and declare they unfurl only during April showers. In July, a sweetly mawkish, many-seeded fruit, resembling a yellow egg-tomato, delights the uncritical palates of little people, who should be warned, however, against putting any other part of this poisonous, drastic plant in their mouths. Physicians best know its uses. Dr. Asa Gray's statement about the harmless fruit "eaten by pigs and boys" aroused William Hamilton Gibson, who had happy memories of his own youthful gorges on anything edible that grew. "Think of it, boys!" he wrote; "and think of what else he says of it: 'Ovary ovoid, stigma sessile, undulate, seeds covering the lateral placenta each enclosed in an aril.' Now it may be safe for pigs and billygoats to tackle such a compound as that, but we boys all like to know what we are eating, and I cannot but feel that the public health officials of every township should require this formula of Dr. Gray's to he printed on every one of these big loaded pills, if that is what they are really made of."

BLOODROOT; INDIAN PAINT; RED PUCCOON (Sanguinaria Canadensis) Poppy family

Flowers - Pure white, rarely pinkish, golden centered, 1 to 1 1/2 in. across, solitary, at end of a smooth naked scape 6 to 14 in. tall. Calyx of 2 short-lived sepals; corolla of 8 to 12 oblong petals, early falling; stamens numerous; 1 short pistil composed of 2 carpels. Leaves: Rounded, deeply and palmately lobed, the 5 to 9 lobes often cleft. Rootstock: Thick, several inches long, with fibrous roots, and filled with orange-red juice. Preferred habitat - Rich woods and borders; low hillsides. Flowering Season - April-May. Distribution - Nova Scotia to Florida, westward to Nebraska.

Snugly protected in a papery sheath enfolding a silvery-green leaf-cloak, the solitary erect bud slowly rises from its embrace, sheds its sepals, expands into an immaculate golden-centered blossom that, poppy-like, offers but a glimpse of its fleeting loveliness ere it drops its snow-white petals and is gone. But were the flowers less ephemeral, were we always certain of hitting upon the very time its colonies are starring the woodland, would it have so great a charm? Here to-day, if there comes a sudden burst of warm sunshine; gone tomorrow, if the spring winds, rushing through the nearly leafless woods, are too rude to the fragile petals - no blossom has a more evanescent beauty, none is more lovely. After its charms have been displayed, up rises the circular leaf-cloak on its smooth reddish petiole, unrolls, and at length overtops the narrow, oblong seed-vessel. Wound the plant in any part, and there flows an orange-red juice, which old-fashioned mothers used to drop on lumps of sugar and administer when their children had coughs and colds. As this fluid stains whatever it touches - hence its value to the Indians as a war-paint - one should be careful in picking the flower. It has no value for cutting, of course; but in some rich, shady corner of the garden, a clump of the plants will thrive and bring a suggestive picture of the spring woods to our very doors. It will be noticed that plants having thick rootstocks, corms, and bulbs, which store up food during the winter, like the irises, Solomon's seals, bloodroot, adder's tongue, and crocuses, are prepared to rush into blossom far earlier in spring than fibrous-rooted species that must accumulate nourishment after the season has opened.

A newly opened flower which is in the female stage has its anthers tightly closed, and pollen must therefore be carried from distinct plants by the short-tongued bees and flies out collecting it. No nectar rewards their search, although they alight on young blossoms in the expectation of finding some food, and so cross-fertilize them. Late in the afternoon the petals, which have been in a showy horizontal position during the day, rise to the perpendicular before closing to protect the flower's precious contents for the morrow's visitors. In the blossom's staminate stage, abundant pollen is collected by the hive bees chiefly; but, those of the Halictus tribe, the mining bees and the Syrphidae flies also pay profitable visits. Inasmuch as the hive bee is a naturalized foreigner, not a native, the bloodroot probably depended upon the other little bees to fertilize it before her arrival. For ages this bee's small relatives and the flowers they depended upon developed side by side, adapting themselves to each other's wants. Now along comes an immigrant and profits by their centuries of effort.

DUTCHMAN'S BREECHES; WHITE HEARTS; SOLDIER'S CAP; EAR-DROPS (Bicuculla Cucullaria; Dicentra cucullaria of Gray) Poppy family

Flowers - White, tipped with yellow, nodding in a 1-sided raceme. Two scale-like sepals; corolla of 4 petals, in 2 pairs, somewhat cohering into a heart-shaped, flattened, irregular flower, the outer pair of petals extended into 2 widely spread spurs, the small inner petals united above; 6 stamens in 2 sets; style slender, with a 2-lobed stigma. Scape: 5 to 10 in. high, smooth, from a bulbous root. Leaves: Finely cut, thrice compound, pale beneath, on slender petioles, all from base Preferred Habitat - Rich, rocky woods. Flowering Season- - April-May. Distribution - Nova Scotia to the Carolinas, west to Nebraska.

Rich leaf mould, accumulated between crevices of rock, makes the ideal home of this delicate, yet striking, flower, coarse-named, but refined in all its parts. Consistent with the dainty, heart-shaped blossoms that hang trembling along the slender stem like pendants from a lady's ear, are the finely dissected, lace-like leaves, the whole plant repudiating by its femininity its most popular name. It was Thoreau who observed that only those plants which require but little light, and can stand the drip of trees, prefer to dwell in the woods - plants which have commonly more beauty in their leaves than in their pale and almost colorless blossoms. Certainly few woodland dwellers have more delicately beautiful foliage than the fumitory tribe.

Owing to this flower's early season of bloom and to the depth of its spurs, in which nectar is secreted by two long processes of the middle stamens, only the long-tongued female bumblebees then flying are implied by its curious formation. Two canals leading to the sweets invite the visitor to thrust in her tongue, and as she hangs from the white heart and presses forward to drain the luscious drops, first on one side, then on the other, her hairy underside necessarily comes in contact with the pollen of younger flowers and - with the later maturing stigmas of older ones, to which she carries it later. But, as might be expected, this intelligent bee occasionally nips holes through the spurs of the flower that makes dining so difficult for her - holes that lesser fry are not slow to investigate.

According to the Rev. Alexander S. Wilson, bumblebees make holes with jagged edges; wasps make clean-cut, circular openings; and the carpenter bees cut slits, through which they steal nectar from deep flowers. Who has tested this statement about the guilty little pilferers on our side of the Atlantic?

SQUIRREL CORN (Bicuculla Canadensis) Poppy family

Flowers - Irregular, greenish white tinged with rose, slightly fragrant, heart-shaped, with 2 short rounded spurs, over 1/2 in. long, nodding on a slender scape. Calyx of 2 scale-like sepals; corolla heart-shaped at base, consisting of 4 petals in 2 united pairs, a prominent crest on tips of inner ones; 6 stamens in 2 sets; style with 2-lobed stigma. Scape: Smooth, 6 to 12 in. high, the rootstock bearing many small, round, yellow tubers like kernels of corn. Leaves: All from root, delicate, compounded of 3 very finely dissected divisions. Prferred Habitat - Rich, moist woods. Flowering Season - May-June. Distribution - Nova Scotia to Virginia, and westward to the Mississippi.

Any one familiar with the Bleeding-heart (B. eximia) of old- fashioned gardens, found growing wild in the Alleghanies, and with the exquisite White Mountain Fringe (Adlumia fungosa) often brought from the woods to be planted over shady trellises, or with the Dutchman's breeches, need not be told that the little squirrel corn is next of kin or far removed from the pink corydalis. It is not until we dig up the plant and look at its roots that we see why it received its name. A delicious perfume like hyacinths, only fainter and subtler, rises from the dainty blossoms.

BULBOUS or SPRING CRESS

(Cardamine bulbosa; C. rhomboidea of Gray) Mustard family

Flowers - White, about 1/2 in. across, clustered in a simple terminal raceme. Calyx of four sepals; corolla of 4 petals in form of a cross; 6 stamens; 1 compound pistil with a 2-lobed style. Stem: 6 to 18 in. high, erect, smooth, from a tuberous base. Leaves: Basal ones rounded, on long petioles; upper leaves oblong or lance-shaped, toothed or entire-edged, short petioled or seated on stem. Fruit: Very slender, erect pods about 1 in. long, tapering at each end, tipped with a slender style, the stigma prominent; 1 row of seeds in each cell, the pods rapidly following flowers up the stem and opening suddenly. Preferred Habitat - Wet meadows, low ground, near springs. Flowering Season - April-June. Distribution - Nova Scotia to Florida, west to Minnesota and Texas.

Pretty masses of this flower, that look like borders of garden candy-tuft planted beside some trickling brook, are visited and cross-fertilized by small bees, of the Andrena and Halictus clans chiefly. How well the butterflies understand scientific classification with instinct for their sure guide! The caterpillar of that exquisite little white butterfly with a dark yellow triangular spot across his wings, the fulcate orange-tip (Euchloe genutia), a first-cousin of the common small white cabbage butterfly, feeds on this plant and several of its kin, knowing better than if the books had told it so, that all belong to the same cross-bearing family. The watery, biting juice in the Cruciferae - the radishes, nasturtiums, cabbage, peppergrass, water-cress, mustards, and horseradish - by no means protects them from preying worms and caterpillars; but ants, the worst pilferers of nectar extant, let them alone. Authorities declare that the chloride of potassium and iodine these plants contain increase their food value to mankind.

The PURPLE CRESS (C. purpurea), formerly counted a mere variety of the preceding, has now been ranked as a distinct species. Its purplish-pink flowers, found about cold, springy places northward, appear two or three weeks earlier than those of the white spring cress.\ The MEADOW BITTER-CRESS (or CROSS), LADIES' SMOCK, OR CUCKOO-FLOWER (C. pratensis), an immigrant from Europe and Asia now naturalized here north of New Jersey from coast to coast, lifts its larger and more showy white or purplish-pink flowers, that stand well out from the stem on slender pedicels, in loose clusters above watery low-lying ground in April and May.

"Lady-smocks all silver white"

now paint our meadows with delight, as they do Shakespeare's England; but ours have quite frequently a decided pink tinge. The light and graceful growth, and the pinnately divided foliage, give the plant a special charm. In olden times, when it was counted a valuable remedy in hysteria and epilepsy, Linnaeus gave it its generic name Cardamine from two Greek words signifying heart-strengthening.

More bees, flies, butterflies, and other insects visit the ladies' smock than perhaps any other crucifer found here, since it has showy flowers and so much nectar the long-persistent sepals require little pouches to hold it. No wonder this plant has triumphantly marched around the world, leaving its relatives that take less pains to woo and work insects far behind in the race. Owing to a partial revolution of the tall stamens away from the stigmas, a visitor in sipping nectar must brush off some pollen on his head or tongue, although in stormy weather, when the movement of the stamens is incomplete, self-pollination may occasionally occur, according to Muller.

TWO-LEAVED TOOTHWORT; CRINKLE-ROOT (Dentaria diphylla) Mustard family

Flowers - White, about 1/2 in. across, in a terminal loose cluster, the formation of each similar to that of bulbous cress. Stem: 8 to 15 in. high. Root stock: Long, crinkled, toothed, fleshy, crisp, edible. Leaves: 2, opposite or nearly so, on the stem, compounded of 3 ovate and toothed leaflets; also larger, broader leaves on larger petioles from the rootstock. Fruit: Flat, lance-shaped pods, 1 in. long or over, tipped with the slender style. Perferred Habitat - Rich leaf mould in woods, sometimes in thickets and meadows. Flowering Season - May. Distribution - Nova Scotia to the Carolinas, west to the Mississippi.

Clusters of these pretty, white, cross-shaped flowers, found near the bloodroot, claytonia, anemones, and a host of other delicate spring blossoms, enter into a short but fierce competition with them for the visits of the small Andrena and Halictus bees then flying to collect nectar and pollen for a generation still unborn. In tunnels underground, or in soft, partially decayed wood, each busy little mother places the pellets of pollen and nectar paste, then when her eggs have been laid on the food supply in separate nurseries and sealed up, she dies from exhaustion, leaving her grub progeny to eat its way through the larva into the chrysalis state, and finally into that of a winged bee that flies away to liberty. These are the little bees so constantly seen about willow catkins.

Country children, on their way to school through the woods, often dig up the curious, long crisp root of the toothwort, which tastes much like the water-cress, to eat with their sandwiches at the noon recess. Then, as they examine the little pointed projections on the rootstock, they see why the plant received its name.

Another toothwort found throughout a similar range, the CUT-LEAVED TOOTHWORT, or PEPPER-ROOT (D. laciniata), has its equally edible rootstock scarcely toothed, but rather constricted in places, giving its little tubers the appearance of beads strung into a necklace. Its white or pale purplish-pink cross-shaped flowers, loosely clustered at the end of an unbranched stem, rise by preference above moist ground in rich woods, often beside a spring, from April to June - a longer season for wooing and working its insect friends than the two-leaved toothwort has attained to - hence it is the commoner plant. Instead of having two leaves on its stem, this species spreads whorls of three leaves, thrice divided, almost to the base, the divisions toothed or lobed, and the side ones sometimes deeply cleft. The larger, longer petioled leaves that rise directly from the rootstock have scarcely developed at flowering time.

SHEPHERD'S PURSE; MOTHER'S HEART (Bursa Bursa-pastoris; Capsella Bursa-pastoris of Gray) Mustard family

Flowers - Small, white, in a long loose raceme, followed by triangular and notched (somewhat heart-shaped) pods, the valves boat-shaped and keeled. Sepals and petals 4; stamens 6; 1 pistil. Stem: 6 to 18 in. high, from a deep root. Leaves: Forming a rosette at base, 2 to 5 in. long, more or less cut (pinnatifid), a few pointed, arrow-shaped leaves also scattered along stem and partly clasping it. Preferred Habitat - Fields, roadsides, waste places. Flowering Season - Almost throughout the year. Distribution - Over nearly all parts of the earth.

>From Europe this little low plant found its way, to become the commonest of our weeds, so completing its march around the globe. At a glance one knows it to be related to the alyssum and candy-tuft of our gardens, albeit a poor relation in spite of its vaunted purses - the tiny, heart-shaped seed-pods that so rapidly succeed the flowers. What is the secret of its successful march over the face of the earth? Like the equally triumphant chickweed, it is easily satisfied with unoccupied wasteland, it avoids the fiercest competition for insect trade by prolonging its season of bloom far beyond that of any native flower, for there is not a month in the year when one may not find it even in New England in sheltered places. Having vanquished in the fiercer struggle for survival in the Old World, it finds life here one long holiday; and finally, by clustering a large number of relatively small flowers together, it attracts the insects that this method of arrangement pleases best, the flies (Syrphidae and Muscidae) which cross-fertilize it in fine weather, transferring enough pollen from plant to plant to save the species from degeneracy through close inbreeding. However, the long stamens standing on a level with the stigma are well calculated to self-pollenize the flowers, the flies failing them.

VERNAL WHITLOW-GRASS (Draba verna) Mustard family

Flowers - Very small, white, distant, growing on numerous scapes 1 to 5 in. high; in formation each flower is similar to all the mustards, except that the 4 petals are 2-cleft, destroying the cross-like effect. Leaves: 1/2 to 1 in. long, in a tuft or rosette on the ground, oblong or spatulate, covered with stiff hairs. Preferred Habitat - Waste lands, sandy fields, and roadsides. Flowering Season - February-May. Distribution - Throughout our area; naturalized from Europe and Asia.

An insignificantly small plant, too common, however, to be wholly ignored. Although each tiny flower secretes four drops of nectar between the bases of the short stamens and the long ones next them, it would be unreasonable to depend wholly upon insects to carry pollen, since there is so little else to attract them. Therefore the anthers of the four long stamens regularly shed directly upon the stigma below them, leaving to the few visitors, the small bees chiefly, the transferring from flower to flower of pollen from the two short stamens which must be touched if they would reach the nectar. In spite of the persistency with which these little blossoms fertilize themselves, they certainly increase at a prodigious rate; but how much larger and more beautiful might they not be if they possessed more executive ability

A similar but larger plant, with its hairy leaves not only tufted at the base, but also alternating up the stiff stem, is the HAIRY ROCK-CRESS (Arabis hirsuta), whose white or greenish flowers, growing in racemes after the usual mustard fashion, are quickly followed by very narrow, flattened pods two inches long or less. Around the world this small traveler has likewise found its way, choosing rocky places to display its insignificant flowers throughout the entire summer to such small bees and flies as seek the nectar in its two tiny glands. It is not to be confused with the saxifrage or stone-breaker.

ROUND-LEAVED SUNDEW; DEW-PLANT (Drosera rotundifolia) Sundew family

Flowers - Small, white, growing in a 1-sided, curved raceme of buds chiefly. Calyx usually 5-parted; usually 5 petals, and as many stamens as petals; usually 3 styles, but 2-cleft, thus appearing to be twice as many. Scape: 4 to 10 in. high. Leaves: Growing in an open rosette on the ground; round or broader, clothed with reddish bristly hairs tipped with purple glands, and narrowed into long, flat, hairy petioles; young leaves curled like fern fronds. Preferred Habitat - Bogs, sandy and sunny marshes. Flowering Season - July-August. Distribution - Labrador to the Gulf of Mexico and westward. From Alaska to California. Europe and Asia.
