Subspecies 3 (3 in the flora).
Braya glabella is extremely variable, sometimes even within a population, and the species has often been split into taxa based primarily on fruit attributes. When the species is examined from its entire range, the perceived morphological gaps blur into a bewildering array of overlapping forms. On the basis of morphological and molecular evidence (S. I. Warwick et al. 2004) it is difficult to justify the recognition of more than one species in this very plastic group, but it does seem useful to divide the species into three fairly distinctive subspecies. Some populations will be readily separable into one of these subspecies, but others will likely defy unequivocal placement, particularly those from areas where the ranges of the subspecies meet.
