Description Rhizomes absent. Culms densely tufted, 0.6-3 cm tall, 0.5-0.8 mm thick, erect, smooth. Leaf sheath brownish, 0.5-2 cm, thinly membranous, glabrous, mouth white hyaline and with scattered long hairs; leaf blade filiform, 4-10 cm × 4-8 mm, abaxially glabrous or sometimes sparsely pilose, margin entire, apex acuminate. Involucral bracts 2 or 3, setaceous, 1-2.5 cm or ± short, very slender, abaxially glabrous or with scattered hairs. Inflorescences terminal, capitate, 5-12 mm thick, with 3-15 sessile spikelets. Spikelets narrowly ovoid, 3-6.5 × 1-1.5 mm, angular, 7-13-flowered, base obtuse to subrounded, apex acute. Glumes brownish to yellowish green turning eventually pale brownish, ovate to nearly broadly ovate, 1.5-2 × 1-1.5 mm, keeled, membranous, apically occasionally pubescent, margin ciliolate, apex with a recurved short awn. Stamens 1(or 2); anther oblong, apex acute. Style filiform; stigmas 3. Nutlet pale brown to yellowish, obovoid-globose, ca. 0.8 × 0.5-0.6 mm, 3-sided, obscurely tuberculate with transversely rectangular cells, apex rounded to emarginate; persistent style base depressed globose. Fl. and fr. Jun-Nov. 2n = 10. [details]

Description Culms terete, glabrous, 5–30 cm high, 0.25–0.3 mm diam. Leaves much shorter than culms, glabrous (except for long white hairs at mouth of sheaths), 0.2–0.3 mm wide. Inflorescence head-like, hemispherical, with 3–20 spikelets, 5–15 mm diam., or rarely a solitary spikelet; involucral bracts 1–3, somewhat shorter than inflorescence, 5–20 mm long. Spikelets ovoid to oblong, acute, 3–8 mm long, 1–1.5 mm diam. Glumes mucronulate (mucro finally excurved), strongly keeled, 1.5–2.3 mm long, glabrous or only minutely pubescent or ciliate on margins, pale to red-brown with green midrib. Stamen 1; anther 0.5–0.7 mm long. Style 3-fid. Nut triquetrous, broad-ovoid, 0.5–0.8 mm long, 0.4–0.6 mm diam., smooth, finely reticulate by the minute isodiametric epidermal cells, whitish to straw-coloured. [details]

Description Herbs, annual, densely cespitose, scapose, low. Culms 5–20(–30) cm. Leaves to 2/3 length of scapes; sheaths greenish or tan, glabrous or hispidulous on ribs; blades spreading, filiform, 0.5 mm wide, involute, margins scabridulous. Inflorescences: scapes filiform, coarsely few ribbed, to 0.5 mm thick; spikelets in terminal headlike, involucrate clusters, 1–1.5 cm wide; involucral bracts with setaceous blades rarely exceeding inflorescence. Spikelets red to red-brown or dull brown, lance-ovoid to lanceoloid or linear oblong; fertile scales lanceolate, keeled, 1.2–2.2 mm, glabrous, midrib excurrent as mucro. Flowers: stamens 1; anthers oblong, 1 mm. Achenes trigonous, obovoid, 0.5–0.6 mm, angles often sharp, faces flat or slightly concave, finely reticulate; tubercle a small button. 2n = 10. [details]
