The family Apocynaceae (Apocynoideae, Rauvolfioideae) from Guatemala

Abstract

The family Apocynaceae s. str. (subfamilies Apocynoideae and Rauvolfioideae) is revised for Guatemala, Central America. Thirty one genera and 59 species are treated, including five introduced genera (Allamanda, Beaumontia, Catharanthus, Nerium, and Vinca). The most species-rich genus is Mandevilla with six taxa, followed by Echites, Prestonia, Stemmadenia, and Tabernaemontana (4 species), and Cascabela (3 species). No endemic species are reported. Keys, descriptions, common names and representative specimen citations are included, together with an appendix with the complete list of material examined. Lectotypes for Cameraria oblongifolia and Echites biflorus are designated.
