Bombay; hills of Salsette Isld. in stony places, Jacquemont (n. 797). 



Stem 3-4 ft., as thick as a goose-quill below, leafy above, branches erect, nodes 

 glabrous. Leaveti 12-18 by f in., finely acuminate, narrowed from the middle to the 

 base, almost petioled, thin, sparsely hairy above and beneath, margins smooth, mionb 

 jtont pale, nerves obscure; sheath of lower 6 in. and upwards, terete, quite glabrous, 

 of upper passing into compressed lanceolate fig. spathes 3-4 in. long, which alternate 

 in very slender axillary branchlets, the lower with leafy tips ; ligule short, scanons. 

 Spikes about 2 in. long, more or less exserted from the spathes, very slender, pale 

 straw-colrd. ; joints and pedicels more than half as long as the sessile^ spikelet, 

 compressed, one angle ciliate. Gl. I of sessile spilcelet white with silky hairs, tbinl)

 margins equally involute from base to 2-fid or truncate 2-cu8pidate tip; callus very 

 short, bearded ; II chartaceous, dorsally convex, nerveless but with a nerve-ii»^ 

 fold towards the ciliate margin, keel with long cilia above the middle, scabrid toward* 

 the emarginate tip ; III shorter, hyaline, obloBg-lanccolate, obtuse, 3-nerved, margm 

 above with reflexed hairs ; palea lanceolate, 2-nerved, anthers imperfect ; IV as to^S
