Plants short-stemmed perennials with fine roots. Leaves ensiform-linear, 1 5-20 cm long, distichous, flabellately spreading, strictly basal, longer than the scape sheaths; blades flat to slightly twisted, 3-5 mm wide, flattened, yellow-green, inconspicuously multi-nerved, papillose, thick-nerved toward margin, reddish brown; apices abruptly narrowed, incurved- acute, thickened; margins with edges pale villous-ciliate; sheaths ciliate-carinate, the sides strongly multicostate, smooth, yellowish-fuscous, castaneous toward the base, rugulose, with margins gradually narrowing into the blades, gradually expanding below, abruptly dilated at base, there the edges narrowly scarious, antrorsely long-ciliate with white hairs. Scape sheaths ancipital toward base, pilose-ciliate, smooth, multicostate, reddish brown, shining, acutely carinate from middle to apex, the carinae reddish, ciliate, the blades short, obtuse. Scapes slender, straight, 4.5-6 dm high, slightly twisted, narrowly 2-3-costate," elliptic in cross section, ancipital toward the apex, the costae longciliate with white hairs. Spikes broadly ovoid, 1-1.5 cm long, obtuse, the bracts numerous, loose, nearly uniform, spirally imbricate, subscarious, convex, ecarinate, broadly ovate, 5- 7 mm long, rounded, brownish yellow, marginally squarrose, lacerate; dorsal area indistinct; sterile bracts many. Lateral sepals free, strongly curvate, slightly exserted, strongly inequilateral, broadly oblanceolate, thin, 6-7 mm long-; keel wide, ciliate-fimbriolate. Petal blades suborbicular to reniform, 7-8 mm long, strongly erose, yellow. Staminodia bibrachiate, the branches flattened, long-penicillate. Anthers lanceolate-oblong, sagittate, ca. 2 mm long. Capsule turgidly obovoid, ca. 3 mm long, the placentation basal; seeds numerous, ellipsoid, 0.5 mm long, palely or deeply lustrous brown, prominently longitudinally 12-1 4-costate.
