rays often 2 in the lower tiers, the longest up to 6 in. long, carrying 
several secondary tiers ; simple rays very finely filiform, l-§ in. 
(or of the lowest tiers to 1J in.) long ; lower subtending leaves resemb- 
ling the preceding leaves, their blades almost reaching to the top of 
the panicle, the upper becoming rapidly spatheoloid. Spatheoles 
linear-lanceolate, finely acuminate, lj-lf in. long, scarious, glabrous 
or with a few scattered hairs, pale reddish, soon narrowly inrolled ; 
peduncles filiform, arching or strongly recurved upwards, with long 
(3 lin.) stiff yellow tubercle-based spreading hairs from the curva- 
ture, exserted subterminally from the spatheole, at length equalling 
the latter and straightening out. Racemes subparallel, finally 
sharply epinastically reflexed, loose, about \ in. long, inconspicu- 
ously hairy, straw-coloured or pale olive-green, 2-3-awned per pair ; 
bases subequal, very short, dark pubescent in the fork, with a 
beard of long rigid yellowish hairs from the tips which often bear 
short ovate purplish auricles up to over J lin. long ; joints (if 
any) and pedicels finely filiform, subobliquely truncate, shortly 
ciliate, the former about 1-1 1 lin., the latter up to 2 lin. long. 
Homogamons pair of spikelets 1 at the base of the lower raceme 
only. Fertile spikelets linear-oblong, subacuminate, 3-3 J lin. long 
including the callus, pale or slate-colour about the middle with 
reddish tips ; callus slender, acute, up to J lin. long, shortly bearded. 
Glumes equal, thinly chartaceous ; lower minutely truncate, flat 
or slightly rounded on the back, sometimes more or less depressed 
along the middle nerve, scabrid all over or shortly pubescent at 
least downwards, faintly 7-9-nerved, margins involute, indexed at 
the tips, keels obscure, scaberulous ; upper glume obtuse or obliquely 
truncate, 3-nerved, sparingly ciliolate upwards. Lower floret 
reduced to an oblong obtuse hyaline 2-nerved ciliate valve. Upper 
floret : valves stipitiform, obscurely 2-dent, ate ; awn stout, 
2- 3 in. long, column fulvous or dark brown, hirtellous, bristle slightly 
paler ; valvule 0. Pedicelled spikelets neuter, sublinear, very 
narrow, 3-3 J lin. long ; lower glume up to 11 -nerved, scaberulous 
on the intracarinal nerves and scabrid on the keels, produced into 
a very fine bristle up to 3J lin. long ; upper acute, membranous, 
3- nerved: valve 1, reduced to a small ciliate hyaline scale or 0. 
Homogamous spikelets slightly stouter than the pedicelled, muti- 
cous, their valve less reduced.

Annual, over 3 ft. high. Culms erect from a subgeniculate base, 
throwing out stilt-roots, slender to somewhat stout, terete, glabrous, 
branched or simple below the panicle. Leaf-sheaths loose, the 
lowest slipping off the culm, not very firm, glabrous or more or less 
hirsute, particularly upwards, with spreading’ tubercle-based hairs ;
