Origin: Native

Notes: There is no single contemporay resource for the taxonomy and floristics of the genus Viola in Washington. As a result, the treatment here lacks a consistent taxonomic concept for what occurs in the state. Considerable work has been done on Viola since H&C, rendering that resource largely obsolete. The Jepson Manual and Jepson Manual, 2nd Edition contain contemporary treatments based on the work of John Little, however many Viola taxa in WA do not occur in California. The Illustrated Flora of British Columbia treatment has been referenced here where possible, but it too does not contain treatments for all of the WA Viola taxa.
