Setaria jubiflora

Setaria jubiflora is a tufted annual or short-lived perennial grass in the Poaceae family belonging to the foxtail or bristle-grass genus Setaria, whose members are distributed widely across the warmer regions of the world. Like its congeners it produces slender, erect to slightly geniculate culms with flat, lanceolate green leaf blades and conspicuously ciliate ligules. The inflorescence is a dense, cylindrical, spike-like panicle that becomes long-haired with the persistent, bristle-like sterile branches characteristic of the genus, and tends to droop when ripe. Each tiny ovoid spikelet, less than 3 millimetres long, is subtended by one or several rough bristles considerably longer than the spikelet itself, giving the inflorescence a soft, plumose appearance. The fertile floret is enclosed by a hardened, finely transversely wrinkled lemma at maturity. Like other bristle grasses, S. jubiflora typically occurs in open, seasonally dry grasslands, savannas and disturbed roadsides on sandy to loamy soils.
