Rhynchospora curvula is the most distinct species of the section Plumososetosae in its narrow spikelets, which are normally greenish in contrast to brownish in others. The leaves in this species are slender and elongated in inland localities, while they tend to be somewhat broader and short in sandy or coastal localities. The specimens cited above mark a considerable range extension of this rare species into Colombia and Venezuela since it has hitherto been known only from Trinidad and the Guianas.
