Abstract

Koyamaea neblinensis W. Thomas & Davidse, gen. et sp. nov., from Cerro de la Neblina, Venezuela and Brazil, is described and illustrated. Because of its bisexual spikelets, each bearing one pistillate flower and many staminate flowers, presence of well-developed glumellae in both kinds of flowers, spirally arranged glumes, and regular fruit without a cupule, Koyamaea is classified as a new genus of Sclerioideae. It is probably not closely related to any other genus in the subfamily and is, therefore, placed in its own tribe, the Koyamaeae W. Thomas & Davidse, tribus nov.
