long, tightly folded, 1-1 J lin. wide when flattened out, rigid, glabrous 
or with some long hairs at the base, scabrid along the margins and 
the keel, lateral nerves prominent below, 2-3 on each side. Racemes 
up to 3| in. long, stiff or slightly flexuous, on long slender exserted 
peduncles, glabrous, greenish. Rhachis rather tough ; joints 
linear, about 2J lin. long, slightly scaberulous along the outer angle, 
otherwise smooth and glabrous, very tardily disarticulating with 
an oblique scar ; pedicels very similar, more slender. Sessile 
spikelet lanceolate-oblong, 3 lin. long, excluding the glabrous callus 
which is over 1 lin. long, glabrous. Glumes equal ; lower obscurely 
acuminate, very minutely 2-toothed, very shortly ciliolate towards 
the apex, intracarinal nerves 6, faint, balsam-ducts conspicuous in the 
brown margin ; upper glume lanceolate, acute, glabrous, 3-nerved, 
with a few transverse veins near the apex. Lower floret about 2J- 
lin. long : valve linear-oblong, subobtuse, minutely ciliolate above, 
2-nerved ; valvule 0. Upper floret 1 J lin. long : valve oblong, 
subacute, sub -3-nerved, ciliolate ; valvule 0. Anthers slightly over 
1 lin. long. Stigmas purple, over 1 lin. long Pedicelled spikelet 
very similar to the sessile, but smaller (2-2J lin. long), <$ or barren, 
the lower glume with 4 intracarinal nerves.

Culms erect, 2-3 ft. high, slender, glabrous, slightly waxy below the 
nodes, terete, many-noded, with flowering branches from the upper 
nodes. Leaf-sheaths terete, tight, the lower longer, the upper some- 
what shorter than the internodes, glabrous, smooth ; ligules re- 
duced to a ciliolate rim ; blades linear, setaceously involute, tapering 
to a fine point, 3-7 in. long and 1-1J lin. wide if flattened out, 
glabrous, smooth excepting the rough margins, midrib and lateral 
nerves very slender, prominent below. Racemes on long slender 
exserted peduncles, or the lateral partly enclosed in the supporting 
sheath, 1J~3 in. long, slightly curved, silky-villous ; joints linear, 
about 1J lin. long, densely villous with the hairs 1J-2 lin. long ; 
pedicels similar, 1 lin. long, very slender. Sessile spikelet lanceo- 
late-oblong, including the long-bearded callus and the mucros 3-3J 
lin. long. Glumes unequal ; lower acuminate, with a slender deeply 
2-fid acumen which is up to 1 lin. long, glabrous on the back, densely 
ciliate along the keels with the hairs up to over 1 lin. long, intra- 
carinal nerves 6, balsam-ducts conspicuous ; upper glume linear - 
lanceolate, acute, 2 lin. long, minutely pubescent on the back, 
finely 3-nerved. Lower floret under 2 lin. long : valve linear- 
oblong, acute, ciliolate, 2-nerved. Upper floret over 1 lin. long : 
valve similar to that of the lower floret, obscurely 3-nerved ; 
valvule 0. Pedicelled spikelet reduced to the glumes and one 
valve, narrowly lanceolate, over 2 lin. long. Glumes subequal, 
mucronate-acuminate ; lower rigidly ciliolate and with a balsam-
