Graptopetalum glass ii from C olima, Mexico, is described and illustrated. It is closely related to G. pentandrum, differing in being smaller and in having a herbaceous habit and a larger number of oblanceolate pale green leaves. Graptopetalum pentandrum subsp. superbum is raised to species rank. Characters that support the change of status are a larger size of the plants, a squamose surface of the stem, a pink-violet color of the rosette, oblong-obovate leaves, and a profusely branched inflorescence.
