Abstract

SECCO, Ricardo de S.. Additional notes on taxonomy and geographic distribution of the genera Alchorneopsis Muell. Arg., Cleidion Blume and Polyandra Leal (Euphorbiaceae - Acalyphoideae). Acta bot. bras. [online]. 2001, vol.15, n.1, pp.45-56. ISSN 0102-3306.  http://dx.doi.org/10.1590/S0102-33062001000100006.

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.

Keywords : Taxonomy; Euphorbiaceae; Alchorneopsis; Cleidion; Polyandra; Amazonia.
