Abstract

Cyperus paramoensis G. C. Tucker (Cyperaceae) is described from Boyaca, Colombia, as a new species. It occurs in páramo vegetation in the northern Andes of Colombia and Venezuela. Its closest relative is C. svensonii G. C. Tucker, from which it differs in its shorter culms, 1–3(−5) cm tall, and dull brown spikelets. This species is placed in Cyperus L. subg. Cyperus sect. Umbellati (C. B. Clarke) Kük., because it has cylindrical spikelets with a winged deciduous rachilla and one or two (three) floral scales.
