Panicum subquadripara Trin., Gram. Panic. 145. 1826.
Urochloa subquadripara (Trin.) R. D. Webster, Austral. Paniceae 252. 1987; Veldkamp, Blumea 41: 429.
1996.
Culms slender, straggling or suberect, often spreading, rooting at lower nodes, nodes pubescent.
Blades 3-15 cm long, 4-8 mm wide, glabrous or sparsely pilose, margins scabrous; sheath usually
shorter than internode and more or less ciliate on margins; ligule a row of hairs, 1-2 mm long. Racemes
3-6, spreading, rather distant along glabrous or sparsely hairy axis; rachis flattened, glabrous or sometimes
with scattered stiff hairs. Spikelets solitary, elliptic, 3.1-4.3 mm long, gglabrous; glumes 5-7-
veined; lower lemma faintly 5-veined; anther ca. 1.2 mm long.
The tropics of the Old World, and introduced elsewhere. Taiwan, in lowland open waste places,
roadsides and moist grassy places.
