Technical Description: Culms densely cespitose to 1 meter tall, sharply triangular rough throughout. Leaves 5-15 mm wide, prominently septate nodulose. Pistillate spikes 2-6, approximate, or the lowest separate cylindric, 3-7 cm long, about 1cm thick, spreading or drooping, lower long peduncled, upper shorter peduncled. Bracts leaflike, much exceeding the inflorescence. Pistillate scales with small reddish brown bodies, the pale midvein excurrent into a rough awn as long or longer than the perigynia. Perigynia reflexed at maturity, slender, ovoid 4.2 to 6.2 mm (avg 5 mm) long, stipitate, trigonous, strongly 12-17 nerved, tapering into the long beak, it's teeth nearly straight and parallel, 0.6 to 1 mm long.
Diagnostic Characteristics: Spikes more than one, stigmas three, achenes triangular; lateral spikes few, not lacerate winged; perigynia glabrous, style continuous with achene, not jointed; perigynia strongly nerved abruptly contracted to the beak, finely and closely ribbed.
