A fan of leaves reddish at the base
Inflorescence pale yellowish, 1 ft. or more high
Ovary obovoid to ellipsoid; stigmas much- branched, forming a dense mass.
Leaves linear, flattened, glabrous, tapering to the asymmetrically obtuse apex.
Seeds ellipsoid to broadly ellipsoid, with 12–13 longitudinal ridges joined by rather prominent cross-walls.
Peduncles glabrous, hollow, terete but markedly 2-winged particularly towards the apex; spikes broadly ovoid to subspherical, later ovoid; sterile bracts 4, broadly obovate to suborbicular, pale golden brown with a subterminal narrowly ovate greyish dorsal mark; fertile bracts suborbicular to elliptic, very convex, golden brown with a dull brown to grey subapical triangular dorsal mark.
Lateral sepals curved, golden brown, with an entire keel; corolla yellow.
Staminodes branched, the branches bearing tufts of hairs.
Coarse, annual herb, up to 400 mm tall. Leaves distichous, 2-8 from a small base. Scape ancipitous, uniformly green. Spikes many-flowered. Bracts stramineous. Flowers yellow.
Soft herbs up to c. 0.7 m tall. Leaves distichously arranged, each shoot consisting of a scape enveloped basally by 1-2 leaves and a sheath, linear, up to 240 x 5 mm, apex acute. Scapes 2-3 times as long as leaves, strongly two-edged, especially so above; sheath resembling leaf but shorter. Spikes broadly ellipsoid to spherical, up to c. 14 mm tall, many-flowered. Bracts numerous and rather regularly spirally arranged, broadly ovate, acute, convex, shiny, yellow to olive green, with a grey diamond-shaped depression below acute apex, often splitting with age. Lateral sepals short and curved, folded, with a glabrous entire keel. Perianth typical. Capsule flattened, oblong, obtuse; seeds ellipsoid, 0.3-0.5 mm, typical.
