Stem 6-18 in., branched and straggling, nodes glabrous or sparingly bearded. 

 Leaves 14 in., linear-lanceolate, acuminate, glabrous or sparsely hairy, base of 

 upper rounded, of lower narrowed ; sheath lax, mouth hairy ; ligule obscure. Spikes 

 1-2 in., rather slender ; joints and pedicels about half as long as the spikelet, nearly 

 equal, shortly ciliate. Sessile spikelets -j^-i in., greenish, or with green nerves; 

 callus narrow, long-bearded ; gl. I margins broadly involute below, subauricled, 

 dorsally convex, polished, nerves strong; II recurved, 3-5-nerved, tip 2-toothed, 

 dorsally usually ciliate; III lanceolate, paleate, palea linear-oblong ; IV glabrous, 

 awn very slender shortly exserted. Pedicelled spikelets like the sessile, awned. A 

 very variable plant, in the form of the leaves especially. Hack el gives four varieties 

 founded on inconstant characters of the leaves and length ot the awn. I have little 

 doubt that I. tenellum, Eoxb., is I. timorense. Had el doubtfully refers it to ciliare, 

 of which it has none of the marked characters. 



Sect. II. SEHIMA (Forsk. Gen.). Spikes solitary. Gl. I of sessile 

 spikelet deeply channelled or depressed along the median line (except 

 I. notatum).

 base narrowed, gl. I of sessile spikelet linear-oblong glabrous 2-cuspidate

 flexuous submarginal nerves, nodose irf the upper half, II awned, IV
