Taxonomic Comments
Windham and Al-Shehbaz (2006) find through analysis of phylogenetics, morphology, and geography that the three sexual diploid entities previously recognized as varieties of Arabis pulchra (e.g., by Rollins (1993), Kartesz (1994 and 1999)) deserve recognition as distinct species: Arabis pulchra var. pallens is treated as Boechera formosa (Greene) Windham & Al-Shehbaz; A. pulchra var. munciensis is treated as Boechera lincolnensis Windham & Al-Shehbaz; A. pulchra var. pulchra is treated as Boechera pulchra s. str. This is the treatment followed in FNA (2010, vol. 7).

Rank Reasons
Arabis pulchra var. pulchra is known from California and Nevada in the United States. It is also known from northwestern Mexico. In California, this species is known from the Great Basin and and the Mojave Desert (Baldwin et al. 2002). In Nevada, this species is known from only two counties that border California (Kartesz 2003). This species occurs on dry slopes, sandy and rocky washes, canyons and foothills (Rollins 1993). In Mexico, this species occurs in northern Baja California on rocky hillsides and along arroyos (Shreve and Wiggins 1964).
