Information

Annual or short-lived perennial herb forming loose clumps. Leaves linear, up to 24 cm. long, 3 mm. wide; sheaths 2–2.5 cm. long, brown with broad membranous margins, rather abruptly narrowing distally; ligule short; lamina linear, flattened, glabrous, smooth; apex acute, weakly asymmetric, pale brown, solid. Peduncles up to 42 cm. long, ± 1.5 mm. in diameter, terete, minutely punctate, longitudinally grooved; peduncle-sheaths similar to the leaf-sheaths; apex with a tuft of blunt hairs which fall off easily; spike obovoid at maturity, up to 1.2 cm. long, 1 cm. in diameter towards the base; sterile bracts membranous, ovate, acute, whitish with a pale brown minutely papillose keel, 7.5 mm. long, 4 mm. wide; fertile bracts ovate, acute, 5 mm. long, 3 mm. wide, pale shining brown, keel papillose, darker brown with a narrowly elliptic pale central papillose mark ± 3 mm. long, 0.5 mm. wide, margins irregularly ciliate-dentate above. Lateral sepals arcuate, pale brown, strongly keeled, the keel regularly dentate along almost its whole length. Corolla, androecium and gynoecium not known. Seeds broadly ellipsoid, 0.4 mm. long, 0.3 mm. in diameter, with 10–12 longitudinal ridges.
