Annual. Culms erect or geniculate, 20–90 cm tall, smooth or scabrous just below inflorescence, nodes glabrous. Leaf sheaths keeled, glabrous; leaf blades linear, 5–40 × 0.2–1 cm, abaxial surface smooth, adaxial surface scabrous or pilose at base; ligule ca. 1 mm. Panicle densely cylindrical, 3–17 × 0.4–0.8 cm; branches reduced to a single mature spikelet subtended by 5–10 or more bristles (sometimes an aborted spikelet also present); axis pubescent; bristles gold, brownish gold or sometimes purple, 2–3 times spikelet length. Spikelets broadly ovate, (2.2–)2.5–3.5 mm; glumes ovate; lower glume 1/3–1/2 as long as spikelet; upper glume 1/2–2/3 as long as spikelet; lower floret usually staminate; lower palea hyaline, ovate, matching the upper floret in size and shape, keels narrowly winged; upper lemma broadly ovate, coarsely rugose. Fl. and fr. Jun–Oct. 2n = 18, 36.
Loosely tufted annual, 0.05-1.30 m high; culm erect or geniculate, nodes glabrous. Leaf blade 30-300 x 2-12 mm, expanded, soft, thin; ligule a fringed membrane or a fringe of hairs. Inflorescence a cylindrical, spike-like panicle, 10-100(-200) mm long; spikelets subtended by 4-10 bristles; bristles 3-12 mm long, slightly scabrid, slender, yellowish, brownish, copper-coloured or greenish with golden-brown or green apices; bristles persist on axis after spikelets fall. Spikelets 1.5-3.5 mm long, apex acute, not deflexed, dorsiventrally compressed; lower glume 3-nerved. Florets 2; lower floret male or sterile, lemma widely grooved; upper floret bisexual, lemma indurated, rugose to corrugate, rarely almost smooth, entire; anther 0.6-1.5 mm long. Flowering time Dec.-May.
Loosely tufted annual 50-1 300 mm high; culm erect or geniculate, node glabrous. Leaf blade 30-300 x 2-12 mm, expanded, soft, thin, glabrous or hairy towards ligule. Inflorescence 10-100(-200) mm long, cylindrical, spike-like; bristles 4-10, 3-12 mm long, slender, slightly scabrid, yellowish to brownish, copper coloured or greenish with golden brown apices or green. Spikelet 1.5-3.5 mm long, apex acute, not deflexed; lower glume 3-nerved; lower floret male or sterile, lemma widely grooved, palea ± as long as lemma; upper lemma rugose to corrugate, rarely almost smooth; anther 0.6-1.5 mm long.
Annual; up to 0.9 m high; loosely tufted. Culm nodes glabrous. Leaf blades 45-170 x 5-9 mm. Flowers: panicle cylindrical; spike-like; normally 10 x longer than wide; spikelets 2.0-2.8 mm long; deciduous as a whole; spikelets subtended by 6-10 bristles; bristles antrorsely barbed; often bright yellow but sometimes dark purple-brown; lower glume 3-nerved; upper glume 3-7-nerved; upper lemma rugose to corrugate; lower lemma very finely rugose; lower palea as long as lemma.
Annual, loosely tufted, up to 0.9 m high. Leaf blades 45-170 mm long, 5-9 mm wide. Culm nodes glabrous. Spikelets 2.0-2.8 mm long. Panicle cylindrical, spikelike, normally 10 times longer than wide; spikelets subtended by 6-10 bristles; bristles often bright yellow but sometimes dark purple-brown; lower glume 3-nerved; lower lemma very finely rugose.
Annual, up to 0.9 m tall, culm nodes glabrous. Leaves linear; ligule a fringed membrane. Inflorescence a spike-like panicle. Spikelets 2-2.8 mm long, subtended by 6-10 long, slender, stiff bristles, not falling with spikelets at maturity (see Pennisetum), awnless, 2-flowered; lower floret male or sterile; upper lemma hard, corrugated to rugose.
Annual, loosely tufted (culms erect or geniculate), up to 0.65 m high. Leaf blades 50-170 mm long, 8-12 mm wide. Culm nodes glabrous. Spikelets 2.3-2.7 mm long. Panicle spike-like, usually ovate but up to 5 times longer than wide; bristles 6-10 per spikelet; lower glume 3-nerved; lemma very coarsely rugose.
A millet grass. It is an annual grass. It grows 20-90 cm tall. The leaf blades are linear and 5-40 cm long by 0.2-1 cm wide. The flowering head is like a "fox tail". The flowering head is cylinder shaped. The bristles are orange.
