General Description
Perennial acaulescent herbs with a slender to stout or sometimes brached caudex. Early leaves strongly dissected; margins ciliate, lower surface sometimes faintly hairy (especially on the veins). Summer leaves also deeply incised; petioles to 15 cm long. Stipules narrow, fused to petiole below. Peduncles about equal to or usually longer than the leaves. Sepals mostly 6-8 mm long, usually ciliate; petals 10-20 mm long, violet or reddish-violet, the lower ones white at base and veined with dark violet, the lateral two less strongly dark veined, the lower 3 petals densely bearded; style truncate at summit. Capsules 8-12 mm long, glabrous, yellw-green. Cleistogamous flowers (those that never open for pollination) on short peduncles (adpated from: Brooks & McGregor, 1986, Flora of the Great Plains).
