Wild Rose Rosa acicularis

Plate 25, fig. 1

The pale to deep pink flowers of the Wild Rose come into bloom in early summer. They grow on shrubs 1-3 ft. high which are found on hills, mountain-sides and in open woods at 5000-10000 ft. The scarlet and crimson fruits of the Wild Rose make the bushes ornamental even after the flowers have passed blooming.

Gold Cup, Potentilla Potentilla gracilis

Plate 25, fig. 2

The Potentillas may easily be mistaken for buttercups, though they actually belong to the Rose Family. The scientific name of the genus comes from a Latin word meaning powerful, and refers to the former use of the plants in medicine. This species, called Gold Cup on account of the shape and color of the blossoms, is bright yellow with an orange spot at the base of each petal. The flowers grow on graceful stems 6 in.-3 ft. high and bloom in midsummer. The plants grow in meadows and open woodlands at 5000-10000 ft.

Golden Avens Sieversia turbinata

Plate 25, fig. 3

The Golden Avens also looks like a buttercup with its cup-like, yellow flowers that bloom in midsummer. The plants grow 4-20 in. high and are found on the higher peaks at 10000-14000 ft.

Pink Plumes Sieversia ciliata

Plate 25, fig. 4

The brilliant rose to purple coloring of this flower is found in the sepals, the petals being rather inconspicuous and cream-colored with rose veins. The nodding blossoms of Pink Plumes occur on graceful rose-colored stems 4-18 in. tall and bloom in early summer. They are found on hills at 8000-12000 ft. The fruits form feathery clusters after the petals have fallen.

Creamy Cinquefoil Drymocallis arguta

Plate 25, fig. 6

The flowers of the Creamy Cinquefoil vary from pale cream to a pure yellow. They grow on erect stems 6 in.-4 ft. tall and blossom in early summer. They are widely distributed on prairies, plains, meadows and hillsides at 3000-12000 ft.

Shrubby Cinquefoil Dasyphora fruticosa

Plate 25, fig. 5

The Cinquefoils receive this name from the French and it refers to the five-parted leaves. The Shrubby Cinquefoil has yellow blossoms on erect shrubby stems that form good-sized bushes, or may be only a few inches tall at high elevations. They occur in meadows, along brooks and on gravel-slides at 6000-12000 ft., and bear flowers all summer.
