Discussion
This species is newly added to the flora of western Venezuela and the British Guiana Pakaraimas. The one collection, Maguire et al. 41761, is represented by pistillate plants only. In this collection the fructifications and glumes are some 1 to 1.5 mm longer than in the other specimens (Fig. 8: compare 0 with P). Whether or not this particular collection represents a subspecific taxon cannot at this time be determined.
