nerve and usually 2-4 more or less distinct additional nerves, glabrous dorsal! y 

 or minutely pubescent towards apex, scabrid dorsally on keel, margins incurved, 

 ciliate above, apex usually shortly mncronate. Lower floral glume oblong- 

 lanceolate, hyaline-membranous or little shorter than the upper involucral 

 glume, 1-3-nerved, margins incurved, ciliate, apex acute or short mucronate. 

 Upper floral glume broad -lanceolate to elliptic, shorter than or subequal to the 

 upper involucral glume, hyaline, 1-3-nerved, mucronate, ciliate, mucro short 

 to 1'25 mm. long, but not exserted beyond the apex of the spikelet. Pale ovate, 

 hyaline, ciliate, from i-f the length of the upper floral glume. Pedicelled 

 spikelets similar, but both the involucral glumes are dorsally long villous and 

 usually with 3-5 strong nerves and occasionally 2 additional fainter ones. 

 Lodicules 2, cuneate, glabrous, 05 mm. long. Anthers 3, pale yellow to 

 purple, 2-2'5 mm. long. Stigmas yellow, often tinted with purple, 1-1*5 mm. 

 long. 



To distinguish this species from Saccharum Ravennce Hole gives the follow- 

 ing field-characters : Glaucous narrow leaves, awnless spikelets, smooth 

 leaf -sheaths. 



Locality: Sind (Stocks in herb. Boiss. ex Hackel) .— Gujarat :— (Sedgwick 

 and Sexton). 



Distribution : Northern India in the Punjab and Upper Gangetic Plain. 



Uses : The fibre of the upper leaf-sheaths is used for mats, ropes, etc. It 

 has also been favourably reported on as a paper material (Haines).

Description : A caespitose grass. Culms 2 m. high or slightly higher, solid. 

 Blade glaucous, narrow, about 8 mm. wide ; midrib at base usually occupies 

 ■§• or more of width of blade ; sheath not hirsute, nodes not bearded. Rhachis 

 of racemes fragile. Spikelets 2 at each node of the rhachis, one sessile and 

 finally decidous with the accumbent joint, the other pedicelled finally separating 

 from the pedicel, both 1-flowered, hermaphrodite. Spikelets 4-6 mm. long, 

 muticous ; pedicel 1-g the length of the sessile spikelet ; joint \— § the length of the 

 sessile spikelet. Most pedicels subequal to longer than proper joint ; callus-hairs 

 yellow, shorter than to subequal to the spikelet ; hairs of joint overtopping joint 

 by once to twice the length of joint. Sessile spikelet : Lower involucral glume 

 chartaceous, dorsally densely villous in basal §, villi not overtopping the glume, 

 or overtopping by less than \ the length of the glume. Upper involucral glume 

 chartaceous, dorsally villous in basal £ or f , villi not overtopping or overtopping 

 by less than \ the length of the glume. Lower floral glume sometimes sparsely 

 villous dorsally. Upper floral glume with a very short mucro, P5 mm. long, not 

 exserted beyond apex of spikelet. Pale ciliate, Pedicelled spikelet : Involucral 

 glumes dorsally villous in basal |-|, villi not overtopping or overtopping by less 

 than \ the length of the spikelet ; no additional glumes inside the floral glumes. 



Locality : Sind :— Near Hyderabad (Blatter and McCann D698 !); W. of 

 Tatta (Blatter and McCann D699 !); near Karachi (ex Hackel I.e.). 



Distribution : Afghanistan, Baluchistan, Punjab, Sind.

Description : Culms erect, up to 6 m. high and 17 mm. thick, solid, often 

 slightly fistular just below the panicle, smooth and polished, striate, shortly and 

 finely bearded at the leaf insertions- Leaf-sheath hirsute with bulbous-based 

 hairs, the latter varying in colour from white to yellow or brown, the hairs being 

 more or less deciduous and old sheaths are often rough with the persistent bul- 

 bous bases ; upper sheaths glabrescent, always longer than the proper internode, 

 long ciliate on margins towards the apex. Blade of uppermost leaf of flowering
