NORTH WEST INDIA, from Kashmir and West Tibet to Kunawur, ascending 

 to 12,000ft. DISTRIB. Westward to S. Europe, and tropics generally or sporadi- 

 cally. 



Stems 2-3 ft., erect or geniculately ascending 1 , subsimple, naked above ; nodes 

 naked or shortly bearded. Leaves 1-2 ft. by -rgg- in., glabrous or hairy above, 

 especially towards the base, glaucous, scaberulous above, base rounded ; sheath loose ; 

 ligule very short. Spikes unequal, 1^-3 in., shortly stipitate, usually purplish. 

 Sessile spikelets, gl. I dorsally flat; II lanceolate, mucronulate, keels scabrid above; 

 III oblong-lanceolate, acute, ciliate ; IV awn -f in. Pedicelled spikelets usually 

 darker than the sessile, male ; gl. I lanceolate, 9-uerved, glabrous, keels ciliate 

 above ; II linear-lanceolate, 5-7 -nerved ; III linear-oblong, obtuse, ciliate ; IV very 

 narrow.

 than the spikelets silky, sessile spikelets - in. lanceolate, callus hairs 

 very short, gl. I imperforate sparsely silkily villous below the middle

The DECCAN PENINSULA, Heyne, &c. COROMANDEL, Roxburgh. CEYLON, 

 Thwaites. 



Stem 2-3 ft., terete glabrous. Leaves 6-10 by -3 in., glabrous or fimbriate 

 with long hairs towards the base, upper surface and margins scabrid, lower glaucously 

 pruinose, lateral nerves prominent ; upper margins of the sheath membranous ; 

 ligule very short, ovate, membranous. Spikes flexuous or erect, 2-4 in. long, dull 

 green, subracemose, common rachis smooth, axils bearded, special peduncles - in. ; 

 joints and pedicels slender. Sessile spikelets A-i in. ; gl. I minutely truncate, tip 

 hyaline, keels closely ciliolate and with a few long marginal hairs ; II ciliate, 3- 

 nerved ; III hyaline, oblong, ciliate, 2-nerved or nerveless ; IV awn |- in., base 

 obscurely dilated, palea 0. Pedicelled spikelets longer than the sessile, lanceolate, 

 gl. I 9-nerved, glabrous dorsally, keels scaberulous and ciliate ; II 5-7-nerved ; III 

 ovate-oblong; IV minute or 0. The spikelets vary a good deal in size. The 

 pruinose undersurface of the leaves is a very marked character. Roxburgh's figure 

 of his A. Ischcemum has awns an inch long, but allowance must be made for native 

 artists' work. I have seen only a single specimen of A. oryzetorum, the spikes are 

 very long and flexuous. Hackel distinguishes it from Pseudischcemum by the leaves 

 being scabrous on both surfaces, which they are not in the specimen I have examined. 



16. A. compressus, Hook. f. ; stem tall robust compressed, nodes 

 glabrous, leaves long broad flat, sheaths compressed keeled, spikes very 

 many densely subcorymbosely panicled pale flexuous silky, joints and 

 pedicels very slender, sessile spikelets ^ in. ovate-lanceolate, callus hairs = 

 |- the spikelet, gl. I imperforate 5-7-nerved villous below the middle, 

 keels minutely scabrid. 



The DECCAN, Lisboa (No. 6. A. odoratus), Woodroiv. 



Stem 3-4 ft., as thick as a goose-quill at the base, erect, sparingly branched, 

 leafy. Leaves 1-1J ft. by in., finely acuminate, slightly scaberulous on the 

 margins and both surfaces, a little hairy towards the base ; sheaths strongly com- 

 pressed and acutely keeled, uppermost forming a lanceolate spathe 4-6 in. long to 

 the base of the panicle ; ligule a ciliate membrane. Fascicles of spikes 4-5 in. long,
