Pink Or Pale Corydalis - Capnoides sempervirens
Two other species of this genus are occasionally found in this State, both with low, diffusely spreading stems and with yellow flowers. They are the Yellow Corydalis (Capnoides flavulum (Rafinesque) Kuntze) with flowers about one-fourth of an inch long and short spurred; and the Golden Corydalis (C. aureum (Willdenow) Kuntze) with flowers slightly more than one-half of an inch long and spurs one-half the length of the corolla.
