Holboell's Rockcress (Boechera holboellii (Hornem.) Á.Löve & D.Löve)

Also classified as Arabis holboellii Hornem.

Many older sources, including USDA PLANTS, treat reflexed rockcress (Boechera retrofracta) as a variety of this species, under the name Arabis holboellii var. retrofracta, or less commonly Boechera holboellii var. secunda. We follow POWO's treatment as separate species.
