Discussion
In 1952, plants of Viola initially identified as V. patrinii were collected and reported by C. T. Rogerson to be established in lawns on the campus of Kansas State University, Manhattan, Kansas, where they are still found. S. B. Rolfsmeier recently determined that these plants are V. prionantha. R. B. Kaul reported that V. prionantha occurs along roadsides in Kansas and is also established in the floodplain of the North Platte River in Nebraska, where it was first collected by him in 1992.
