If species have only been collected from a limited number of locations, it is not unusual for the plant designated as the type species to be untypical of the range as a whole, or, for quite contrasting plants of the same species to remain unknown for many years. It seems that this particular taxon bridges the characteristics that separate Sedum rhodocarpum and S. edwardsii. Sedum edwardsii was considered a subspecies of S. rhodocarpum for several years, but even this level of differentiation seems to be far too great. More exploration may show a complete range of intermediate forms from glabrous to extremely hirsute.
