Rhynchospora aristata moritziana (Rhynchospora aristata moritziana)
Description
Rhynchospora (beak-rush or beak-sedge) is a genus of about 400 species of sedges with a cosmopolitan distribution. The genus includes both annual and perennial species, mostly with erect 3-sided stems and 3-ranked leaves. The achenes bear a beak-like tubercule (hence the name -beak-rush-, although the plants are sedges, not rushes) and are sometimes subtended by bristles. Many of the species are similar in vegetative appearance, and mature fruits are needed to make a positive identification. The infloresences (spikelets) are sometimes subtended by bracts which can be leaf-like or showy.
