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

 Leaves 1-4 in., linear-lanceolate, acuminate, glabrous or sparsely hairy, base of 

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

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

 equal, shortly ciliate. Sessile spihelets -ro~i '"•> greenish, or with green nerves; 

 callus narrow, long-bearded ; gl. 1 margins broadly involute below, snbauricled, 

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

 dorsally usually ciliate; HI lanceolnte, paleate, palea linear-oblong ; IV glabrous, 

 awn very slender shortly exserted. Fedicelled spihelets like the sessile, awncd. — A 

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

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

 doubt that I. tenellum, Boxb., is I. timorense. Hacls el doubtfully refers it to ciliare, 

 of which it has none of the marked characters.
