Information
Loosely tufted wiry perennial arising from a knotty base with silky-villous scales; stems straggling, up to 60 cm long. Racemes 2–8, each 4–8 cm long; internodes ciliate to pilose, the hairs increasing in length upwards to 2–3 mm. Sessile spikelet linear to narrowly lanceolate, 5–7 mm long; lower glume chartaceous, strongly convex, pectinate-spinose on the keels and often muricate on the back along the indistinct nerves; anthers 3, 2.5–3.5 mm long; awn of upper lemma 8–15 mm long. Pedicelled spikelet narrowly lanceolate, 4–5.5 mm long, on a pedicel half as long as the internode.
Range
N1, 2 tropical East Africa eastwards through Arabia to India, China and Thailand.
Altitude range

Distribution

Notes
A recent revision of the genus by Welzen, in Blumea 27: 255–300 (1981), places this species in A. lanceolatus. Although the two species are rather similar, the latter, which is confined to southern India, has the lower glume of the sessile spikelet more or less flat on the back and strongly nerved.
