Abstract

Rhynchospora pseudomacrostachya, a new Brazilian species of Cyperaceae. Brittonia 54: 340–343. 2002.—Rhynchospora pseudomacrostachya (Cyperaceae) is restricted to the southern Brazil states of Rio Grande do Sul and Santa Catarina. Previously, material of R. pseudomacrostachya had been thought to belong to R. corniculata var. macrostachya (Torr. ex A. Gray) Britton (R. macrostachya Torr. ex A. Gray) of North America. However, R. pseudomacrostachya can be distinguished from the North American taxon on the basis of achene and inflorescence characters.
