Low mat-forming herb, probably annual. Culms very slender, prostrate, branching and rooting at nodes, flowering branches up to 15 cm tall. Leaf sheaths subglabrous to hispid, outer margin ciliate; leaf blades ovate-lanceolate, 0.6–2 × 0.3–0.4 cm, thinly appressed-hispid, base cordate, apex acute; ligule ca. 0.7 mm. Panicle 1.5–2 cm, sparsely branched, eglandular, spikelets 4–12(–17); branches and pedicels short, stiff, smooth. Spikelets elliptic or obovate, 1.4–2 mm, tinged purplish brown; florets similar; glumes equal to spikelet, separated by a short internode, ovate-oblong, 5–7-veined, hispid above middle, sometimes sparsely or glabrous, obtuse but appearing acute because of incurved margins; lemmas strongly convex, leathery, puberulous. Fl. and fr. Apr–May.
