Small, tight, pale green or glaucous perennials, forming rounded cushions or mats 0.6-2-(6) cm high and up to 10 cm diam., with many culms, much-branched at base; branching intravaginal. Leaf-sheath hyaline, whitish, glabrous, conspicuously, sparsely ribbed, usually completely concealing culms, much wider than and sometimes longer than leaf-blade. Ligule 0.5-1.5-(4) mm, truncate to acute, usually lacerate or fimbriate, abaxially with scattered prickle-teeth. Leaf-blade (0.1)-0.4-1.2-(4) cm × 0.2-0.4 mm diam., involute, spreading and recurved, abaxially smooth, adaxially ribbed, finely scabrid on ribs; margins minutely scabrid, tip obtuse. Culm erect, internodes glabrous. Panicle usually almost hidden among leaf-sheaths, often recurved, contracted to a minute, dense, ovate head 3.5-7 mm, with few or many spikelets; rachis, branches and pedicels very short, minutely, sparsely scabrid. Spikelets 1.5-2 mm, greenish. Glumes ± equal, ovate-lanceolate, acute, keel green, scabrid, margins wide, glabrous, hyaline, minutely ciliate near tip. Lemma 1.2-1.4 mm, glabrous, faintly 5-nerved, ovate-oblong, truncate, awnless. Palea 0.2-0.4 mm, orbicular or ovate. Lodicules 0.2-0.3 mm. Callus glabrous. Anthers 0.4-0.6 mm. Caryopsis 0.7-1 × 0.3-0.4 mm. 2n= 42.

Sheaths hyaline, whitish, smooth and glabrous, with few conspicuous green nerves, usually completely concealing culms, much wider than and sometimes longer than laminae; ligule 0.5-1.5-(4) mm, truncate to acute, usually lacerate or fimbriate, abaxially with scattered prickle-teeth; lamina (0.1)-0.4-1.2-(4) cm long, involute and 0.2- 0.4 mm wide, spreading and recurved, abaxially smooth, adaxially ridged and finely scabrous along ridges, margins minutely scabrous, tip obtuse. Culms erect, smooth. Panicle usually almost concealed among leaf sheaths and often recurved, contracted to a minute, dense, ovate head 3.5-7 mm long, with few or many spikelets; rachis, branchlets and pedicels very short, minutely, sparsely scabrous. Spikelets 1.5-2 mm, greenish. Glumes ± equal, ovatelanceolate, acute, with green scabrous keel and wide, smooth hyaline margins minutely ciliate on edges near tip.
