Spikelets in a round cluster enclosed at base by a set of 5-6 long, drooping, white bracts with green tips; stem triangular.
The striking whitish bracts on this sedge make it appear as if it has showy, daisy-like flowers. These bracts attract insect pollinators, which is unusual in this primarily wind-pollinated family. The genus name is from the Greek rhynchos ("beak") and spora ("seed") and alludes to the beaked achenes.
