Notes: The name Boechera grahamii is the correct one for the northern plant that for long has gone as B. divaricarpa (a much more southern species, se Excluded taxa). Boechera grahamii is apomictic and a hybrid species from B. collinsii (Fernald) Á. Löve & D. Löve (central North American) and B. stricta. See Al-Shehbaz and Windham (2010).
