Weak straggling annual; culms slender, 5–40 cm. long.. Leaf-blades flat, 0.5–13 cm. long, 1–3 mm. wide.. Panicle linear to lanceolate, 1–9 cm. long, the spikelets clustered about the short (2–20 mm.) stiff primary branches, the rhachis glabrous or hirsute.. Spikelets 3–12-flowered, broadly orate, 1.5–5 mm. long, 1.5–3 mm. wide, dark green, breaking up from the base, the rhachilla persistent; glumes ovate, subequal, 1–1.5 mm. long, with or without a few stiff hairs; lemmas broadly ovate to rotund, 1.2–1.7 mm. long, thinly cartilaginous; palea falling soon after the lemma, the keels narrowly winged and scaberulous; anthers 2, 0.5 mm. long.
Weak straggling annual often forming loose mats; culms up to 20(35) cm tall, mostly decumbent, sometimes erect, usually branched, glabrous at the nodes (but often pilose on the internodes), eglandular; leaf sheaths usually pilose with tubercle-based hairs; ligule a line of hairs; leaf laminas 0.5–8(15) cm × 1–4 mm, linear, usually flat, densely pilose (but glabrescent with age), eglandular.
Panicle 1.5–10 cm long, narrowly elliptic to lanceolate-elliptic, open, the spikelets clustered about the short stiff primary branches on stout pedicels 0.3–3 mm long, the primary branches not in whorls, terminating in a fertile spikelet, eglandular, the axis and branches glabrous or pilose.
Caryopsis 0.6–0.8 mm long, broadly oblong-elliptic, the surface conspicuously reticulate.
