Closeup of flower
Viola pubescens, commonly called the downy yellow violet, is a plant species of the genus Viola and is classified within the subsection Nudicaules of section Chamaemelanium.[1] It is a widespread North American violet found in rich, mesic woodlands, and sometimes in meadows, from Minnesota and Ontario east to Nova Scotia and south to Virginia.[2]V. pubescens produces two different types of flowers during the season, including chasmogamous flowers in the early spring and cleistogamous flowers summer through fall.[3]
Similar-looking species include the round-leaved yellow violet (Viola rotundifolia). The two species can be differentiated by leaf shape and leaf margin. Additionally, V. pubescens has both basal and cauline leaves,[2] while V. rotundifolia has only basal leaves.[4]
