Slender Rock Cress (Arabis pycnocarpa M.Hopkins)
Also known as slender rock cress, creamflower rockcress, creamflower rock cress; also classified as Arabis hirsuta var. pycnocarpa (M.Hopkins) Rollins, Arabis hirsuta subsp. pycnocarpa (M.Hopkins) Hultén.
This species was formerly considered by some authorities to be a variety or subspecies of Arabis hirsuta (L.) Scop.; we follow the treatment by POWO, BONAP, and most other contemporary authorities which split that taxon up, treating what was previously considered varieties or subspecies as different species.
