Taxonomy: Previously treated as a variety of A. deserti but morphologically and geographically distinct. Basal rosettes generally single, rarely with 1–3 offsets (vs. basal rosettes copiously suckering and forming large clumps in A. deserti). More closely related to A. mckelveyana (of Arizona) and A. subsimplex (of Sonora, Mexico). |
