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

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

 ciliate. Panicle 314 in. long, branches and pedicels capillary; gl. I and IE obtuse, 

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

 glabrous or pubescent, both often bisexual.

6. I. scabrosa, Hook. f. ; leaves suberect, sheaths scabrid, panicle 

 2-3 in. pyramidal, spikelets aV-yV i n - 



KHASIA HILLS, alt. 4500-5000 ft. Clarke. 



Stem rambling below, then suberect, 13 ft., stiff, sparingly branched. Leaves 

 3-6 by | in., linear-lanceolate, scabrid on bor,h surfaced, 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, smooch, 

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

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

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



7. I. himalaica HooJc.f.; erect, leaves linear or linear-lanceolate 

 strict scaberulous above, margins slightly thickened, sheaths smooth, 

 panicle pyramidal, spikelets -fa-fa i n - globose, pedicels long capillary tips 

 hardly thickened, gl. I and II faintlv manv-nerved. I. anstralis, Aitchis.

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

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

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

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

 longer aud flatter than IV. 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 Munro's herbarium this is referred to the Javan I. virgata, Nees 

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

 as being fastigiate spikelets, and glumes with narrowed obtuse mucronate points. It 

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



8. I. elegrans, Dalzell mss. ; erect, tufted, flaccid, glabrous or nearly 

 so, leaves 2-5 in. very narrowly linear acute soft smooth on both surfaces 

 or scaberulous above, margins thickened, panicle subsessile contracted, 

 branches erect, spikelets V^-iV in - pedicels short, tips rounded, gl. I and II 

 many-nerved.

 mont (n. 143), Woodrow (n. 175). 



Stems 8-12 in., densely tufted, soft. Leaves A- in. broad, principal nerves or 

 1-2 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 -1 in., smooth ; pedicels rarely longer than the spikelets, which - 

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

 hemispheric, but III sometimes longer and natter. The tufted flaccid habit is quite ' 

 unlike /. australis, but may be due to local conditions.
