Padrões de distribuição geográfica dos táxons brasileiros de Eragrostis (Poaceae, Chloridoideae)

Abstract

(Patterns of geographic distribution of the Brazilian taxa of Eragrostis (Poaceae, Chloridoideae)). The genus Eragrostis presents 53 taxa in Brazil, being 38 of them native with distinctive patterns of geographic distribution: exclusively tropical, tropical/subtropical (more abundant in the tropical area but extending their occurrence to the Southern region), tropical and subtropical (as abundant in the tropical region as in the subtropical one), exclusively subtropical, and subtropical/tropical (opposed to the second pattern). An analysis of these patterns is presented together with representative maps.
