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).
