Abstract

We describe and illustrate Paepalanthus magistrae, a remarkable new species of Eriocaulaceae from Northeastern Brazil. The species is placed into Paepalanthus subsect. Dichocladus by the presence of trimerous flower, elongated dichotomous branched stem, and small rigid leaves. Within the section it may be easily distinguished by its leaves with glabrescent adaxial surface and lanose abaxial surface. As the species is narrowly distributed and known from a few populations, it is considered endangered.
