Recent collections of Aster blepharophyllus A. Gray, the first since its discovery in 1851, prompted a reevaluation of its identity. It is properly placed in the genus Machaeranthera as M. gypsitherma Nesom, Vorobik, & Hartman. Within that genus, it shares characters with species of sect. Blepharodon as well as those of sect. Arida (both groups sensu Hartman), but we place it tentatively in the latter group. Of particular significance is its chromosome number of n = 5 pairs, reported for the first time, which is shared with species of sect. Arida.
