A revision of Echeveria pringlei var. parva was made based on morphological and biogeographical comparisons. The results show that this taxon should be raised to the species level and that it belongs to E. ser. Nudae. Since the epithet parva is unavailable for use due to the existence of E. parva, E. flammigera is proposed as a new replacement name. An updated description of the taxon is provided, as well as a distribution map.

Graptopetalum trujilloi (subg. Glassia, Crassulaceae), a new haplostemonous species from San Gabriel municipality, Jalisco, Mexico is described and illustrated.

A key to the haplostemonous species of Graptopetalum is provided and, according to IUCN criteria, the species was assessed as critically endangered (CR).
