Eriocaulaceae na Reserva Natural da Vale, Linhares, Espírito Santo, Brasil

Abstract

Eriocaulaceae comprises ca. 1400 species arranged in ten genera. Most of the taxonomic efforts in the family are focused in the Espinhaço Range, its center of diversity. However, the sand dunes in Brazil have also a significant species richness. This manuscript presents the floristic treatment of the Eriocaulaceae from the Reserva Natural da Vale in Espírito Santo State. A total of nine species distributed in six genera were recorded. The genera Actinocephalus, Comanthera, Leiothrix, and Tonina are represented by one species each, Syngonanthus is represented by two species and Paepalanthus by three species. Photos, descriptions, an identification key, as well as comments on geographic distribution and morphological variation are provided.
