Rhynchospora plumosa Elliott. Common name: Plumed Beaksedge. Phenology: May-Aug. Habitat: Pine savannas, sandhill-pocosin ecotones, especially where the sandy surface dries out in summer (on spodosols such as the Leon soil series). Distribution: NC south to s. FL and west to se. TX; West Indies (Cuba); Belize, Honduras, Nicaragua.

ID notes: Rhynchospora plumosa is a short plant, up to 4.5 dm tall, and with very narrow, filiform leaves. A look at a seed narrows down the ID choices to just a few species of Rhynchospora with feathery seed bristles; see Rhynchospora Key C. In this species the spikelets form dense clusters (cylindrical in outline), versus an open inflorescence composed of a few slender branches in R. oligantha and R. galeana.

Origin/Endemic status: Native
