Abstract:
Complementary data are presented and discussed with regard to the taxonomy and geographic distribution of the genera Alchorneopsis, Cleidion and Polyandra. Alchorneopsis is a probably monotypic genus from Central América, Colômbia, Guiana, Peru and Brazil. Cleidion, with the majority of their 25 species in the paleotropics, has only three species in Tropical America. Polyandra, a monotypic genus, is probably endemic from Brazilian Amazonia. The taxonomic relations of the genera and species are discussed and the Amazonian species are illustrated.
