Habranthus (Amaryllidaceae) do Brasil

Abstract

Habranthus is an ornamental genus with 30-40 species distributed from the southeastern United States and Mexico to South America. Genus and species delimitation are confusing with several situations that need to be clarified. The aim of this study was to conduct a survey of the Brazilian species of Habranthus, and contribute to the knowledge of these species through descriptions, illustrations, identification key and comments on all species. Twenty one species were identified, distributed in Caatinga, Cerrado, Atlantic Forest and Pantanal phytogeographic domains, inhabiting cerrado vegetation, rocky fields, gallery forest, grassland, flooded and disturbed areas.
