ligule short, membranous, truncate, shortly hairy ; blade linear, 

 flat or plicate along the prominent midrib, or subinvolute, glabrous, 

 sparsely hairy on the upper face at the base and on the adjoining 

 mouth of the sheath ; inflorescence with glabrous peduncle 

 exceeding the long narrow shortly acute sheath, false racemes 

 generally 5, comprising two shortly stalked outer pairs and a 

 simple central raceme, slender, weak ; rhachis-joint slightly shorter 

 than the $ spikelet, slender, curved, densely villous, hairs whitish, 

 far exceeding the joint ; sessile spikelet glabrous, lanceolate, outer 

 glume 2-nerved, apex bidenticulate, back concave, margins involute 

 below becoming carinate and scabridulous above the middle ; gl. II. 

 siibequal, one-nerved, navicular, shoi'tly niucronate, mai-gins be- 

 coming hyaline and ciliolate ; gl. III. oblong-lanceolate, l>lunt, 

 hyaline, enerved, edges incurved and ciliolate above ; feitile glume 

 oblong, hyaline, shortly bifid, with a weak apical awn, column only 

 slightly exceeding the spikelet ; pale less than half the length of 

 the glume, blunt ; pedicel of aborted spikelets subequalto rhachis- 

 joint but narrower, similarly hairy, spikelet bluish represented 

 only by the linear-lanceolate a,cuminate outer glume. 



Culms 3 ft. 6 in. high, internode next or next but one above 

 the base 6 in. long, 1 to 1 \ line in diameter ; cauline leaves nearly 

 5 in. or less, 1^ lines wide or less, becoming nari-owev upwards; 

 hgule less than ^r line long; ultimate spathes 31 in, long ; top of 

 peduncle glabrous or minutely and sparsely pilose ; inflorescence 

 subfastigiately spreading 2.V to 3 in. long; common peduncle of 

 lateral pairs of racemes 2 to 3 lines long, pedicel of stalked branch 

 a little shorter ; rhachis-joint a good 2 lines long ; sessile spikelet 

 2^ lines or a trifle le.ss; outer glume bluish, keel of gl. II. scabrid- 

 ulous in the upper half ; gl. III. scarcely 2 lines long ; fertile 

 glume H Hne long, awn ?, in. flexuose, scabridulous, pale .V line 

 long, lodlcules narrowly cuneate | line, anthers (3) linear, | line 

 long ; ovary glabrous, styles slightly shortei- than the stigmas ; 

 pedicelled spikelet 1 to 11 line long, glume 1 -nerved with margins 

 carinulate and scabridulous except in lowei- third. 



Near A . eucomus Nees, but distinguished by its larger spikelets, 

 ■constant presence of the aborted (^ spikelet, laxer false racemes, etc.
