Abstract

A new, non-climbing species from the Guiana Shield is described and illustrated: Matelea graciliflora (Apocynaceae, Asclepiadeae, Gonolobinae). The new species is morphologically similar to M. herbacea and M. palustris (together the only other erect species of Gonolobinae in the Guianas), but can be differentiated by a number of characters, including perianth and corona dimensions and corolla color. A synopsis of the erect members of the Matelea palustris complex in the Guianas and northern Brazil is provided.
