VIOLET FAMILY
Reading edition
Yellow Violet Viola biflora
Plate 5, fig. 1
The plants of the Yellow Violet are low and the deep-green leaves often form carpet-like masses along the moist edges of brook-banks at 7000-11000 ft. The flowers are small and yellow with red-brown stripes, the lower petal hanging down in the form of a lip. They bloom from spring to early summer.
Prairie Violet Viola pedatifida
Plate 5, fig. 2
The flowers of the Prairie Violet are large and deep blue, though albino forms are sometimes found. The plants are stemless and only a few inches high, blooming on prairies at 3000-6000 ft. from April to June. The Prairie Violet may easily be mistaken for the Bird’s-foot Violet of the East on account of its deeply cut leaves, which serve also to distinguish it from the Blue Violet so common in woodlands.
