or linear-lanceolate, glabrous or sparsely hairy beneath ; margins thickened, 

 scaberalous; midrib and 3-5 pairs of principal nerves distinct, mouth of sheath 

 ciliate. Panicle 3-14 in. long, branches and pedicels capillary j gi. I and II obtuse, 

 glabrous or sparsely setulose, usually pale green, faintly many-nerved; III and IV 

 glabrous or pubescent, both often bisexual.

Stem rambline; below, then suberect, 1-3 ft., atifif, sparins;ly branched. Leaves 

 3-6 by i-^ in., linear-lanceolate, scabrid on both surfaces, pale and strongly-nerved 

 beneath, margin thickened ; mouth of sheath sparingly ciliate. Panicle very 

 shortly peduncled ; branches erecto-patent, 1-1^ in. long; pedicels capillary, smooth, 

 tips not swollen. Spikelets sparsely setulose, tips rouuded ; gl. I and II glabrous 

 or sparsely setose, many-nerved. — Easily distinguished from P. albens and hima'aiea 

 by the scabrid leaf-sheaths : but most nearly allied to the latter.

Stem 1-2 ft., erect from the base, stout or slender, stiff. Leaves always narrow 

 Q -i in.), nearly ensifonn ; nerves 9-11 pair, usually very strong, margins thickened ; 

 mouth of sheath stifBy ciliate. Panicle with erecto-patent branches l-lj in. long. 

 Spikelets green or purplish ; gl. I and II glabrous scabrous or bristly. III sometimes 

 li>nger and flatter than IT. — Very like I. australis, but a larger and more rigid 

 plant, with gl. II and III usually equal, and both hemispheric. 



In a note in Monro's herbarium this is referred to the Javan I. virgata, 'Sees 

 (Miq. Fl. Ind. Bat. iii. 462^ Panicum rhabdinum, Stend.), but that is described 

 as being fastigiate spikelets, and glumes with narrowed obtuse mucrouute paints. It 

 closely resembles a Sumatran plant from Beccari (u. 198).

Stems 8-12 in., densely tnfted, soft. Leaves i— J in. broad, principal nerves or 

 1-3 on each side, margins thickened, smooth or serrulate, rarely with a few 

 scattered bristles beneath ; sheath quite smooth, mouth ciliate. Panicle 3-5 in., 

 glabrous ; branches -^-l in., smooth ; pedicels rarely longer than the spikelets, which 

 are hispid green or blneish, gls. Ill and IV pubescent, usually equal and both 

 hemispheric, but III sometimes longer and flatter.- — The tnfted flaccid habit is quite 

 unlike I. aitstralis, but may be due to local conditions.
