Discussion | Within the flora area Phemeranthus brevicaulis has been known most generally as Talinum pulchellum, which was based on a collection from Queen, New Mexico. However, P. brevicaule, which was described earlier (as T. brevicaule) from the Santa Eulalia Mountains in Chihuahua, Mexico, differs in no significant respect, and that epithet has priority when the two entities are merged.
