Taxonomic Comments
Al-Shehbaz, in the Flora of North America (vol. 7, 2010) treatment (followed here) includes Arabis hirsuta var. glabrata in A. eschscholtziana, saying "Both M. Hopkins (1937) and R. C. Rollins (1941, 1993) recognized the glabrous or subglabrate forms native to North America as a distinct variety, var. glabrata; G. A. Mulligan (1996) did not accord such forms any taxonomic status. Glabrous and subglabrate forms occur in both Arabis eschscholtziana and A. pycnocarpa and sometimes even within a population that has moderately to densely pubescent forms. I support Mulligan’s view in not recognizing the glabrous forms as an infraspecific taxon." Kartesz (1994) treated them as distinct varieties of A. hirsuta.
