22 CLXXIII. GBAMINEJ5. (J. D. Hooker.) [Isachne. 



hispid or bristly ; III and IV subequal or III rather the largest, glabrous or 

 puberulous. I. Neesiana, is rather more glabrous, and has rather more unequal 

 gls. Ill and IV, but these characters are too variable to found a distinct variety 

 upon. 



Var. latifolia; stem 12-16 in. stouter, leaves 2-3 by -f in. and sheaths 

 sparsely hairy, midrib and 2-3 pairs of principal nerves d'istinct. Nilghiri Hills, 

 alt. 6000 ft., Lawson; Anamallay Hills, Seddome. Almost intermediate between 

 I. Kunthiana and elatior. 



2. Z. elatior, Hook.f.\ nearly glabrous, stem 2-4 ft., nodes tomen- 

 tose, leaves 3-4 in. ovate-lanceolate acuminate thin scabrid above, panicle 

 5-7 in., branches many slender, gl. I and II subcuspidate 5-9-nerved. 



CEYLON, Gardner; Newera Ellia, Thwaites (CP. 314). 



Included by Thwaites under I. Kunthiana, possibly correctly, but a very different 

 looking plant, from its great size, thin leaves and much larger many-fld. panicle, 

 with longer branches. \ 



3. I. Xiisboee, Hook.f. ; glabrous, stem creeping, branches ascending, 

 leaves thin oblong-lanceolate, panicle with, few horizontal stout hispidly 

 setulose branches, gl. I and II 5-nerved hispid, III and IV equal. 



The CONCAN ; Mahableshwar, Lisboa. 



Stem creeping for several inches with long wiry roots, then ascending, and 6 in. 

 high, rather stout. Leaves 1-2 in. by in., recurved, thin, acute or obtuse, finely 

 striate ; base rounded, margins ciliate ; sheaths loose ; lignle 0. Panicle with the 

 rachis quite smooth. Spikelets -^ in. diam., secund on the lower surface of the 

 branches, sessile or shortly pedicelled ; gl. I and II hemispheric, 5-rihbed, tip 

 obtusely cuspidate, a little larger than III which is glabrous. I have seen but one 

 specimen of this species, which probably varies like its congeners in the smoothness 

 or hispidity of the spikelets. The 5-ribs of gl. I and II are good characters. 



ft Glumes I and II much shorter than IV.

CEYLON ; Oova district, alt. 5000 ft. , Thwaites. 



Stem 1-2 ft. or more, branched, and sheaths smooth. Leaves 4-6 by -J in., 

 smooth, deeply striate, margins hardly thickened, nerves obscure. Panicle 4-7 in. ; 

 branches many, long, suberect, and very short pedicels subcapillary. Spikelets 

 Jo in., glabrous, glistening, purplish; gl. I oblong-ovate, 7-nerved ; * II as long, 

 glabrous; III oblong-lanceolate, empty ; IV much shorter, broadly oblong, obtuse, 

 glabrous. 



ttt Glumes I and II about equalling IV. 



Glumes III and IV usually equal and similar, both hemispheric and 

 coriaceous.
