Plants annual, cespitose, delicate, to 30(–40) cm, bases soft; rhizomes absent. Leaves polystichous, spreading to ascending, to 1/2 length of culms or longer; sheaths entire or ciliate distally, backs hirtellous; ligule absent; blades linear-filiform, 0.5 mm wide, flat or involute, scabrid ciliate, often abaxially hirtellous. Inflorescences: anthelae simple or compound, mostly open, ascending-branched, mostly longer than broad; scapes filiform, 0.5 mm wide, distally compressed, mostly glabrous; longer involucral bracts leafy, equaling or exceeded by anthela. Spikelets greenish brown or brownish, lanceoloid or narrowly ellipsoid-cylindric, 4–5 mm; fertile scales ovate, acute, glabrous, midrib excurrent as slender, excurved cusp. Flowers: stamens 1; styles 2-fid, slender, base flat, long-fimbriate, hairs recurved over achene summit. Achenes pale brown, lenticular, obovoid, 0.9 mm, smooth or very finely reticulate.
Tufted, often spreading annual, us. white-pubescent in all its parts. Culms 3–16–(20) cm. × c. 0.5 mm., ∞, flaccid. Lvs us. < culms, filiform; sheaths much broader, light brown. Infl. us. a compound umbel, 1–4 cm. long, occ. reduced to a few spikelets only; subtending bracts 3–4, lf-like, 1–2 often > umbel. Spikelets 3.5–5–(7) mm. long, us. stalked, pale brown. Glumes ∞, elliptic, with a prominent, rigid, green, scabrid keel, often forming an excurrent mucro, and often recurved in the lowermost glume of a spikelet. Stamens us. 1. Style 2-fid, the bulbous base ringed with fine cilia hanging downwards over the ovary, not quite reaching to the mid-point. Nut slightly < 1 mm. long, c. 0.5 mm. diam., biconvex, orbicular, smooth, cream.
Tufted, erect annual, 100-300 mm tall. Leaf blades flat, up to 1 mm wide. Inflorescence of several stalked clusters of spikelets, each individually stalked, radiating from stem apex, basal bracts suberect, leaf-like. Spikelets ovoid-oblong, 3-5(-9) x 1.5-2 mm, glumes light brown, aristate. Style base with long white hairs enveloping nutlet when young.
Annual herb, up to 150 mm tall. Style base bearing many long, white, pendant hairs which form a fringe over nut. Glumes light brown.
Green to buff-coloured oblong spikelets, glumes scarious a conspicuous green midvein excurrent in a long recurved awn
