New species, new records, and a checklist of Coenogonium (Ostropales: Coenogoniaceae) from Brazil

Abstract

The genus Coenogonium, the only genus in the family Coenogoniaceae, is mostly found in tropical and subtropical regions. Approximately 100 species of Coenogonium are known worldwide, and about 52 species have been previously recorded from Brazil. Here, we describe four species as new to science from the Atlantic Forest in the states of Bahia, Minas Gerais, and Sergipe, and present a few new state records. The new species are C. carassense, C. itabaianense, C. pilosum, and C. subtomentosum. An annotated checklist of the species of Coenogonium from Brazil is also included.
