Abstract

The genus Oligonema comprises seven species, five of them with worldwide distribution. In this paper, we describe the occurrence and geographical distribution of Oligonema species in Brazil, based on herbarium specimens and author collections in various states and ecosystems. We report Oligonema for the first time in the Midwest region as well as in Cerrado and Caatinga biomes. Here we present descriptions of O. flavidum, reported for the first time in Pernambuco state, and O. schweinitzii, reported for the first time in Mato Grosso state. These two species are rare in Brazil and occupy mangrove, tropical rain forest and savannah environments. This work expands current knowledge on the occurrence and distribution of Oligonema in the Neotropics.
