Flowers bisexual; perianth of 6–9 retrorsely barbed bristles, slightly longer than achene; stamens 3; styles 2-fid, base persistent, linear. Achenes biconvex. x = 16.
"Spikelets crowded in rather short, axillary spikes of mostly 7–10, distichous on the rachis; scales distichous, each subtending a perfect fl, their margins hyaline and decurrent on the eventually disarticulating rachilla as a hyaline wing; bristles 6–9, retrorsely barbed, exceeding the achene; stamens 3; style bifid; achene flattened, linear-oblong; tall, rhizomatous perennial sedges with subterete, hollow, jointed, leafy stems, numerous short blades and numerous short-peduncled spikes solitary in the upper axils.
