88 INDIAN FOREST MEMOIRS. 



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

 bulbous bases. 



Upper sheaths glabrescent. 



Always longer than" the proper internode. 



Long ciliate on margins towards the apex. 



Lamina. Of uppermost leaf of flowering culm from 8 in. long and 0-25 in. wide, linear and 



tapering from base, to 2\ ft. long and 0-65 in. wide with greatest width about the middle. 



Lower leaves attain a length of 6 ft. and width of 1^ in. Are usually 4 — 5 ft. long and 

 1 in. wide. 



Greatest width about the middle, sometimes in upper third. 



Dark green, midrib white. 



Apex acuminate, narrowed towards the base. 



In basal leaves the concave midrib occupies \ or more of width of lamina at base (often 

 the entire width of the leaf). 



Densely villous above towards the base with bulbous-based hairs, more or less scaberu- 

 lous along nerves, margins scabrid. 



Liguie. A narrow membranous rim not exceeding 0-07 in. high. Entire and rounded or deeply 



2-lobed, patently hairy dorsally with stiff white hairs. 



Ciliate. 



inflorescence. Spikelets in pairs, one pedicelled and one sessile on the capillary jointed branchlets 



of an ample terminal panicle. 



Primary rachis sulcate, scabrid on ridges. Primary branches compound sub- 

 verticillate. 



Flowering panicle, 1 — 3 ft. long, lanceolate, brownish red in colour with spreading 

 branches. Fruiting panicle oblong, dirty white or brown in colour, branches closely 

 adpressed to rachis. , 

 spikeiets. Distinctly awned, lanceolate acuminate. 



0-13 to 0-16 in. long. Exserted part of awn usually about equal to length of spikelet 

 (from \ to \\ times the spikelet). 



Sessile and pedicelled similar, each one flowered and # • 



Pedicelled spikelet at length falling from the pedicel, sessile falling with the attached 

 pedicel and joint of axis. Joints and pedicels villous with long pale purplish or brownish 

 hairs. Hairs of joint overtop joint by about twice the length of the joint. 



Joints \ to | sessile spikelet. Pedicels \ to f sessile spikelet. Majority of pedicels 

 longer than proper joint. 



Callus hairs shorter than to subequal the spikelet, purplish or brownish in colour
