Annual, up to 3 ft. high. Culms erect or geniculate-ascending,, 
terete, rather slender, simple, about 3-noded, glabrous and smooth. 
Leaf-sheaths terete, somewhat loose, striate, ciliate along the outer- 
margin, otherwise glabrous, shorter than . the long internodes ; 
ligules rounded, membranous, J lin. long, ciliate ; blades linear from 
an attenuated base, long-tapering to a slender point, up to over 14 ft. 
by 3-5 lin., flat, flexuous or flaccid, glabrous or very sparsely hairy 
and ciliate upwards, margins scabrid, midrib slender or in the 
longest leaves stouter and more prominent downwards, primary 
lateral nerves 4-5 on each side, fine. Panicles contracted or slightly 
open, loose, narrow, over 1 ft. long, slightly nodding or erect, with 
their base at length shortly exserted from the uppermost sheath, 
glabrous, divided to the third or fourth degree, all the divisions filiform 
to subcapillary, angular and scabrid or the primary smooth at the 
base ; primary axis slender, subterete and grooved or very angular 
and smooth below ; primary branches scattered, often widely 
distant or the lowest whorled, up to almost 1 ft. long, very loosely 
divided from J-1J in. above the base ; branchlets very long and 
remotely divided from high above the base, the penultimate divisions 
representing very loose usually 2-spiculate racemes ; pedicels hardly 
thickened upwards, with truncate tips, the lateral 3-4 lin., the 
terminal up to 6 lin. long. Spikelets broad- or elliptic-oblong, sub- 
subulate-acuminate, hardly turgid, 3 lin. long, glabrous, green or 
tinged with dull purple. Glumes falling with the spikelet, mem- 
branous, finely and prominently nerved ; lower ovate-oblong 
mucronate-acuminate, equalling three-quarters of the lower- 
floret, 7- or sub-7 -nerved ; upper broad-oblong, subsubulate- 
acuminate, the tip laterally compressed, broadly rounded on the 
back, 9-nerved, nerves more prominent upwards. Lower floret 
barren : valve similar to the upper glume but less acuminate, sub- 
9-nerved, the innermost side-nerves evanescent below the upper 
third ; valvule slightly shorter, oblong, truncate or subacute ; 
stamens rudimentary or 0. Upper floret broad-elliptic-oblong, 
obtuse, 2 lin. long, brown, smooth and shining. — Steud. Syn. PI.
