Viola hallii is a species of violet known by the common names Oregon violet and Hall's violet. It is native to southwestern Oregon and northwestern California , where it occurs in open areas in the forests and chaparral of the coastal mountain ranges, on gravelly soils, often of serpentine origin.[1]
Description
This rhizomatous herb produces a cluster of hairless stems reaching a maximum height of about 22 centimeters. The leaves are each divided into three fleshy leaflets which are deeply divided into lance-shaped lobes and borne on short petioles, very similar to Viola beckwithii. A solitary flower is borne on a long, upright stem. It has five petals, the lower three cream-colored with yellow bases and red veining, and the upper two dark red or purplish.
