Taxonomic revision of tarenaya (cleomaceae)(1)

A taxonomic revision of the species currently circumscribed in Tarenaya Raf. (Cleomaceae) is presented here. Tarenaya comprises 38 species distributed from Mexico to Argentina (except for Chile) and the West Indies, and with one species disjunct in Central Africa. We present a new combination, 14 lectotypifications, and two neotypifications, and describe a new species endemic to Espirito Santo, Brazil. We provide a detailed description of the genus, an identification key to the species, and, for each species, we provide descriptions, geographic distribution data, and preferred habitats, diagnostic features, morphological comments, extinction risk assessment, photographs, illustrations, and distribution maps.
