brous; joints and pedicels stout, clavate or oblong-clavate, truncate, 
much contracted at the base and shortly bearded there, otherwise gla- 
brous, shining, yellowish. Sessile spikelets all heterogamous, laterally 
compressed, tightly wedged in between joint and pedicel, linear- 
lanceolate in front view, acuminate, 3J-4 lin. long, including the 
glabrous callus. Glumes equal, lower firmly chartaceous, shining, 
shortly 2-dentate, deeply concave or grooved between the keels 
which are obtuse and smooth up to the acumen, and acute and 
scaberulous in the acumen, nerves 3 on each side in and near the 
keel ; upper glume boat-shaped, acute, chartaceous, ciliolate, 3-nerved, 
keel acute above and almost smooth. Lower floret reduced to an 
oblong acute ciliolate 2-nerved valve. Upper floret ^ : valve 
oblong, 2-fid, eciliate, 1| lin. long, awn slender, 7-8 lin. long, kneed 
at the middle ; valvule oblong, 2-fid, nerveless, § lin. long. Anthers 
| lin. long. Grain oblong, over 1 lin. long. Pedicelled spikelet 
lanceolate, acutely acuminate, about 3 lin. long, greenish, glabrous ; 
lower glume mucronulate, with about 9 very close and fine nerves ; 
upper somewhat shorter, very acute, 3-5-nerved, ciliolate, mem- 
branous ; valves of both florets hyaline, of the lower 2} lin. long, 
2-nerved and ciliolate, of the upper somewhat shorter, 1-nerved, 
mucronulate; valvule deeply 2-fid ; anthers 1J lin. long. — IscJice-

(base unknown). Culms erect, slender, over 1J ft. long, glabrous, 
smooth. Leaf-sheaths tight, terete, glabrous, smooth, striate, 
shortly auricled, auricles triangular, acute ; ligules truncate, scarious, 
ciliolate, adnate to the auricles of the sheath ; blades linear, long- 
attenuated at the base or contracted into a narrow petiole, tapering 
to a setaceous point, up to 8 in. by 2J lin. wide, flat, flaccid, puberu- 
lous on both sides, turning reddish, scaberulous along the margins 
and nerves, midrib whitish, slender, lateral nerves very fine. In- 
florescence a very narrow spatheate panicle up to 1 ft. long, of up 
to 4 distant 2-rayed tiers, sometimes reduced to a few simple 1-noded 
branches ; spathes resembling the preceding leaves with more or 
less well-developed blades ; rays very slender, subequal, erect, 
strict, 2-2 J in. long. Spatheoles lanceolate-oblong, with a small 
setaceous point or blade, subscarious, slightly tinged with purple, 
glabrous, about 2J-3 in. long, finally more or less tightly inrolled ; 
peduncles at length shortly exserted. Racemes 2-nate, one sessile, 
the other with a short base, 1J-1| in. long, yellowish, nearly quite gla- 
brous ; joints and pedicels very similar, stout, clavate, very convex
