Flora of Espírito Santo: Eriocaulaceae

Abstract

We present a floristic treatment of the Eriocaulaceae from Espírito Santo state. A total of 22 species distributed in seven genera were recorded. Paepalanthus is the richest genus with ten species, followed by Leiothrix and Syngonanthus with three species each, Comanthera with two species, and Actinocephalus, Eriocaulon, and Tonina with one species each. Most of the species occur in the restingas (14 spp.), but the diversity in elevated areas is also relevant. The Paulo Cesar Vinha State Park is highlighted as a conservation unit encompassing ten species. Photos, descriptions, an identification key, as well as comments on geographic distribution and morphological variation are provided.
