Rhizome widely creeping. Cuhn erect, attaining about 12 m. or JBore 

 in height and abont 2 decim. or more in diameter, terete, broadly grooved 

 above, but semiterete in the uppermost portion, fistulose, smooth, green or 

 yellowish ; internodes short ; nodes slightly prominent, but more turged 

 above, pubescent and ringed with white waxy substance below it when 

 young ; main-branches 2 to a culm-node, semiterete, turged at nodes, 

 branchlets usually 1 to 2 to a node. Culm-sheath large, coriaceous, 

 densely pubescent with brown-purple hairs, fimbriate at the top, with a 

 subulate microphyll. Leaves dense, usually 2-8 to a branchlet, lanceolate 

 or angustato-lanceolate, gradually acuminate, shortly attenuated at the base 

 and decurrent to a short petiole, 4-12 cm. long, 5-17 mm. broad, scabrous- 

 margined, chartaceous, green above, more or less pallid beneath, glabrous, 

 but pubescent at the base beneath ; midrib slender ; veins 3-6 on each side ; 

 venules very finely tessellate ; ligule produced, ovate, obtuse-truncate and 

 ciliated at the apex, more or less puberulent on the back ; sheath narrowly 

 terete, often more or less puberulent above, striate, ciliato-margined, with 

 deciduous fimbriate cilia at the mouth. Spikes numerous and often more 

 or less dense, narrowly lanceolato-cylindrical, acuminate at the apex, about 

 5-7 cm. in length, secundly and densely and fasciculately flowered, pedunculate; 

 rachis slender, semiterete, very slightly flexuous, finely pubescent, internodes 

 3-6 mm. in length ; peduncles slender, terete, glabrous, internodes short, nodes 

 very slightly prominent, sheaths deciduous. Bracts narrowly oblong or 

 oblong-lanceolate, spathiform, the largest one about 2|cm. long except 

 the acuminate and lanceolate microphyll at the top, glabrous, or pubes- 

 cent towards the margin, membranaceous, many-nerved, those of the 

 secondary rachises smaller ; bracteoles shorter than bracts, narrowly 

 lanceolate, acuminate, membranaceous, bicarinate, pilose with spreading 

 hairs along the carinro. Spicute erect, very shortly pedicellate, linear- 

 cylindrical, 25-29 mm. long, 1-flowered with a terminal rudimentary
