Taxonomic CommentsTreated as a full species V. glaberrima by Weakley (2022), following work by Ballard. See details and ID criteria in the text for V. tripartita.

General note on Viola: In 2009-10 B.A. Sorrie (website map editor) went through the whole collection at NCU, annotating all specimens against those verified by experts in the genus. The range maps in RAB (1968) have been changed accordingly. More recently, H. Ballard and students are in the process of revising all Southeastern Viola, and they will recognize additional species; this work has now been published (see above). We will follow updated editions of Weakley in recognizing them.
