Panicle spike-like, but often ± lobed or interrupted, 1–20 cm. long, woolly, the spikelets densely clustered.. Spikelets 6–12-flowered, ovate, 2–4.5 mm. long, fluffy, often purplish, breaking up from the apex, the rhachilla fragile; glumes lanceolate, subequal, 0.7–1.2 mm. long, acute; lemmas oblong-elliptic, 0.9–1.5 mm. long, the keels (at least in the upper lemmas) bearing a few short stiff hairs, otherwise smooth, broadly obtuse, ± obscurely mucronate; palea-keels tuberculate-ciliate, the hairs 0.6–0.7 mm. long, exceeding the width of the adjacent floret; anthers 2, 0.2 mm. long.. Caryopsis ellipsoid, 0.3–0.5 mm. long.. Fig. 60/2, p. 190.
Annual. Culms slender, tufted, 10–70 cm tall. Leaf sheaths with long silky hairs; ligules a line of ca. 0.4 mm hairs; leaf blades ca. 15 × 0.3 cm, adaxial surface with silky hairs. Panicle purplish, contracted, spikelike. Spikelets ca. 2 mm, many-flowered. Glumes chartaceous, deltoid-lanceolate,1-veined, apex pointed, lower glume slightly shorter than upper glume, upper glume ca. 1 mm. Lemmas chartaceous, 0.8–1.3 mm, midrib of back with short glandular hairs, glabrous to scabrous along the margins, apex mucronate.

A grass. It is a tufted annual. It grows 5-60 cm high. The leaf blade is flat and 12 cm long by 5 mm wide. The flower panicle is like a spike but interrupted. It is 1-20 cm long and woolly. The spikelets have 6-12 flowers. The seeds are up to 0.5 mm long.
Panicle 4–20 cm long, woolly, narrow and spike-like but often lobed and interrupted, the spikelets densely clustered on pedicels 2–4 mm long, the primary branches not in whorls, terminating in a fertile spikelet, glabrous in the axils, eglandular.
Caryopsis 0.3–0.5 mm long, elliptic.
Annual 15–60 cm. high
