Information
Loosely tufted annual; culms 10–100 cm. high or more, geniculately ascending. Leaf-blades broadly linear, 5–30 cm. long, 4–16 mm. wide, flaccid, glabrous to loosely pilose; sheaths glabrous to pubescent. Panicle spiciform, linear to untidily lobed, 2–15 cm. long, often entangled, the rhachis hispidulous; bristles 3–8 mm. long, retrorsely barbed, tenaciously clinging. Spikelets ellipsoid, 1.5–2.5 mm. long; lower glume 1/3–1/2, the upper as long as the spikelet; lower floret sterile, the palea minute; upper lemma finely rugose. Fig. 127.

Notes
Some authorities recognize two species: temperate S. verticillata with ciliate sheath-margins, glabrous blades and spikelets over 2 mm. long; tropical S. adhaerens with glabrous sheath-margins, hairy blades and spikelets under 2 mm. long (Henrard in Blumea 3: 412 (1940)). However, these are only two from a number of intergrading populations, and it seems better to treat the whole complex as a single polymorphic species. S. verticillata is allied to S. viridis (L.) P. Beauv., a weedy species of temperate regions (bristles antrorsely barbed, rhachis pilose to villous, lower palea up to 1/2 as long as lemma), and to the cultivated S. italica (L.) P. Beauv.
