EOL Text
Annual or sometimes short-lived perennial, varying from a prostrate creeper to a leafy upright plant; culms 10-60 cm high, ascending from a stoloniferous base. Leaf-blades 1-9 cm long, 1-5 mm wide, the blades and sheaths usually glabrous but occasionally hirsute. Inflorescence composed of 24 (typically 2) digitate racemes; racemes 1-10 cm long, the spikelets ternate on a ribbon-like winged rhachis with low rounded midrib; pedicels terete, smooth, with discoid or cupuliform tip. Spikelets narrowly ovate-elliptic, 1.2-1.8 mm long; lower glume a minute hyaline rim; upper glume as long as the spikelet, 5-nerved, with short appressed verrucose hairs between the nerves (sometimes glabrous between 1st and 2nd lateral nerves); lower lemma as long as the spikelet, 7-nerved, pubescent with verrucose hairs or these appressed and barely visible (sometimes glabrous beside midrib and between 2nd and 3rd nerves); fruit ellipsoid, pallid, light brown or light grey.

Annual or short-lived perennial, usually with slender, many-noded stolons. Culms ascending, leafy, 10–40 cm tall. Leaf sheaths pubescent or glabrous; leaf blades broadly linear, 2–5 × 0.2–0.4 cm, glabrous or papillose-pilose at base, apex acute; ligule 1–1.5 mm. Inflorescence digitate; racemes 2–3, arching at maturity, 2–5 cm; spikelets ternate; rachis ribbonlike, winged, 0.5–0.8 mm broad, midrib low and rounded; pedicels terete, smooth, with discoid tips. Spikelets elliptic, 1.2–1.5 mm, apex acuminate, hairs verrucose; lower glume absent; upper glume as long as spikelet, 5-veined, densely appressed-pubescent; lower lemma as long as spikelet, 7-veined, glabrous between middle and lateral veins, otherwise pubescent; upper lemma yellowish brown or pale gray, apex acuminate. Anthers 0.6–0.8 mm. Fl. and fr. Apr–Oct. 2n = 18.

Digitaria fuscescens (Presl) Henr is doubtfully distinct, differing only in its glabrous spikelets. It occurs in Southeast Asia as far west as eastern India.

"Annuals. Culms 10-40 cm long, slender, creeping or geniculate, rooting at the nodes; nodes glabrous. Leaves 2-7 x 0.3-0.7 cm, elliptic-lanceolate, rounded or shallowly cordate at base, apex acute; sheaths keeled; ligules ovate, membranous. Racemes 2 or 3, digitate, 2-7 cm long. Rhachis flat, c. 0.5 mm wide, winged. Spikelets solitary, 1-2 mm long, ovate-elliptic, shortly hairy. Lower glume absent. Upper glume 1-2 x 1 mm, ovate-elliptic, chartaceous, 5-9-nerved. Lower floret empty. Upper floret bisexual. First lemma similar to the upper glume. Second lemma 1-1.5 x 1 mm, ovate-elliptic, crustaceous, Palea 1-1.5 x 0.5 mm, elliptic, 2-keeled, 2-nerved. Stamens 3; anthers c. 0.5 mm. Stigmas c. 1 mm long."
Digitaria fuscescens (J. Presl) Henrard differs from D. longiflora only by its glabrous spikelets and slightly longer, fractionally exserted upper floret. Most likely it is simply a glabrous variant of D. longiflora. It is widespread throughout the tropics, and although reported from S China, no specimens have been seen.
