MESOAMERICANUM     P.Carrillo & Pérez-Farrera, 2012

Sedum mesoamericanum is described as a new species, and illustrated based on collections from the Mexican states of Oaxaca and Chiapas, as well as Guatemala. It is distinguished by the possession of subclasping leaves with denticulate margins. Previous phylogenetic analyses placed this species in a clade of Villadia species from the Sierra Madre del Sur, with which it is compared. Additionally, the morphological similarities of Sedum mesoamericanum to S. goldmanii and S. porphyranthes are discussed.
