'''Rhynchospora''' ('Beak-sedge' or 'Star-sedge') is a genus of about 400 species of
sedges with a
cosmopolitan distribution. The most distinctive feature of the genus is the one to ten or more long
bracts at the base of the inflorescence, resembling a
bird's
beak (if one) or a star, whence the common names. The bracts are typically 3-5 cm long, but in ''R. nervosa'', they can reach 22 cm long.
