Abstract

Three new closely related species of Eleocharis R. Brown (Cyperaceae) from Andean páramos are described from Colombia: E. fassettii S. González & P. M. Peterson, E. cuatrecasii S. González & P. M. Peterson, and E. moraosejoana S. González, C. Ulloa & P. M. Jørgensen. They all belong to Eleocharis subgen. Eleocharis, sect. Eleocharis, and differ from related species by a combination of characters, among which are the thin, loose upper sheath apices and the unusual achene shape that is conspicuously tapered toward the base and apex.
