I found a small colony of bearded violets today in a sunny ditch that stays fairly wet. The plants are young, and only 3" to 4" tall. Stems are smooth. Leaves not well developed, but in shape shown below, or some a bit more pointed. There are no hairs on these plants, except for the beards. The flowers are about the size of my thumbnail, and beard hairs appear rounded at the tips. Of the roughly 21 Viola varieties in Arkansas, the best candidates are V. cucullata, V. nephrophylla, and V. walteri. Sources report that the distinguishing characteristic for V. cucullata is a beard that has club-shaped hairs. Our other bearded species have hairs with sharp ends. Are the hairs in the third photo club shaped? Is this specimen V. cucullata, or something else?
