glabrous, more or less finely striate, darkish green and often purplish ; 

 nodes bi-annular, conspicuously prominent, piloso-tomentcise with purple 

 hairs when young ; internodes long, the longest one about 5 decim, ; main 

 branches erect-patent, 3 to a node of culm and then subfasciculate ; branchlets 

 fasciculate, sub-semiterete, prominent at nodes, with deciduous sheaths 

 which are angustato-lanceolate in the upper ones and subulato-deltoid in 

 the lower ones: Leaves dense, about 3-9 to a branchlet, approximate, 

 lanceolate, or angustato-lanceolate, acuminate with a very sharp point at 

 the aiX'X, obtuse or acute at the base and decurrent to a distinct petiole 

 (which is 3-10 mm. in length), 6-22 cm. long, 1-3^ era. broad, scabro- 

 ciliated on the margin, thinly chartaceous, green and glabrous above, 

 pubescent and subglaucous beneath ; veins 4-8 on each side ; venules very 

 finely tessellate ; ligule short, truncate ; sheath glabrous, ciliated on the 

 margin, striate ; cilia of mouth long (the longest one 1^ cm.) and erect or 

 radiate, deciduous. Culm-sheath ovato-lanceolate, green, purpulish towards 

 the margin, glabrous, but ciliated with patent purple pilose hairs, striate, 

 subpatently dense-pilose with dark-purple hairs at the base, long-ciliated at 

 the top ; ligule erect, short, broad, truncate, minutely ciliated, puberulent 

 dorsally ; microphyll linear or linear-lanceolate, gradually acuminate, ciliato- 

 ecabrous with purple spinulose hairs on margin, chartaceous, green, slightly 

 purplish towards the apex, closely many-nerved. Inflorescence paniculate, 

 cernuo-pendulous, or ascending, loose or rather dense ; peduncles loosely 

 branched, narrow, prominent at nodes, glabrous ; sheath subulato-lanceolate 

 to subulato-linear, chartaceo-membranaceous, ciliated with spreading hairs, 

 striate, l|-4cm. long, with a small deciduous subulate microphyll. Spikelets 

 fasciculately or sub-racemosely disposed, pedicellate, slender, elongate, filiform, 

 loosely and alternately flowered, 8-20cm. long, 2-3 mm. across ; rachilla 

 slender, slightly flexuous, viridescent ; internodes compressed, lato-linear, 

 puberulent above, .5-7 mm. long ; pedicel 3-30 mm. long, gracile, straight, 

 covered with scaly sheaths, few- to several-jointed, puberulent ; sheaths 

 membranaceous, striate, the lower ones shorter and imbricate, subulato- 

 ovate, mucronate or cuspidate, ciliated or subciliated, several- to subnu- 

 merous-nerved, the superior ones gradually longer, the uppermost one oblong- 

 linear, with a minute subulate microphyll or sometimes a normal blade, 

 ciliated on one margin, many-nerved, about 16 mm. long. Flowers erect 

 and adpressed to the rachilla, longer than the internodes, oblong-linear, 

 sharply tapering at the apex, green, glabrous, 7-12 mm. long. Empty 

 glumes 2 or sometimes 3, approximate, sub-closely placed to the lowest 

 floAver, viridescent, acute and with an apiculate scabrous tip, minutely
