Abstract

We describe, discuss, and illustrate Dichorisandra flesheri, a new species endemic to the Atlantic Forest in southern Bahia state, Brazil, based on field and herbarium studies. The species was assessed as ‘Endangered’, especially for its restricted distribution and differs strongly from other species of the genus by a set of characters that includes stem, leaves and inflorescence with a hairy indument, a pendulous inflorescence and flowers with six stamens, anthers slightly sagittate at base, yellowish, opening introrsely with longitudinal slits, but functionally poricidal. Discussion of relevant characters, comparisons with similar species, descriptions, distribution map of the species, information on conservation status and illustrations are provided.
