Discussion

Erysimum inconspicuum is known in Yukon from Raup & Correll 11255 (A), which was collected 7 miles east of Little Atlin Lake, and Malte s.n. (GH), which was collected from Dawson on 10 August 1916. Most of the other collections from Yukon identified as E. inconspicuum belong to E. coarctatum. The record from Quebec is based on Cayouette J80-8 (GH), from Cté de Charlevoix, and Victorin, Germain, & Meilleur 43128 (GH), from Du Lac-Saint-Jean.
