the remainder terete, tight, much shorter than the internodes ; 
ligules very short, truncate, ciliate ; blades folded, linear from the 
base and there narrower than the mouth of the sheath, acute or 
subacute, the lowest over 6 in. long, the upper gradually shorter, 
\\ lin. wide (when unfolded), glabrous or particularly the upper 
with very fine spreading hairs towards the ligule, smooth, 
pale-green. Inflorescences consisting of a terminal corymb of 
racemes augmented by 1 or 2 distant simple branches or 2-rayed 
tiers ; spathes very narrow, with subulate blades ; rays filiform, 
erect, strict or slightly arching, their lower internodes 2-4 in. long. 
Spatheoles subacute, about 2 in. long, glabrous, at length tightly 
inrolled ; peduncles at length distinctly and sometimes long-exserted 
terminally. Eacemes flexuous or nodding, paired, one sessile, the 
other with a short base, about 1| in. long, loosely hairy ; joints filiform 
with clavate cupular obliquely dentate tips, ciliate, l|-2 lin. long, 
hairs white, about \ lin. long ; pedicels very similar, produced on one 
side into a subulate or narrowly linear tooth. Sessile spikelets 
except the basal of the sessile raceme which is $ or barren and 
like its pedicelled companion, linear-lanceolate, 2-2J lin. long, tinged 
with purple ; callus and its beard very short. Glumes about equal, 
the lower very minutely dentate, nerveless and deeply sunk between 
the slightly scaberulous keels, the upper acute, 1-nerved, ciliolate. 
Lower floret reduced to a linear-oblong faintly 2-nerved reversedly 
ciliate valve, 2 lin. long. Upper floret ^ : valve lanceolate-oblong, 
2-fid to one-third, sparingly ciliate ; awn about 6-10 lin. long, column 
4 lin. long, brown, bristle yellow. Anthers 1 lin. long. Pedicelled 
spikelet $ or neuter, linear-lanceolate, acuminate, purple, 2-2J lin. 
long ; glumes unequal, the lower often produced into a fine bristle, 
up to 1J lin. long, 3-nerved, the upper short or 1-nerved ; flowers 
reduced to their valves ; valves oblong, 2 lin. long, hyaline, 1- to 
sub-3-nerved, ciliate, or more or less reduced ; stamens, if present, as 
in the b spikelet.

24. A. cyrtocladus, Stapf in Kew Bulletin, 1^01 ,20^. Suffrutescent, 
up to over 6 ft. high, with much-branched many-noded main-culms ; 
branches usually ascending in curves, glabrous, terete, hard ; lower 
internodes more or less exserted from the persistent or slowly decay- 
ing sheaths, whitish-glaucous, up to 2-f in. long, upper much shorter 
to very short. Leaves crowded on the young branches or more or 
less distant, glabrous ; sheaths terete, tight, firm, smooth ; ligules 
reduced to a minute membranous rim ; blades attenuated from a 
slightly rounded base into a long setaceous peint, from less than 1 to 
ljin. long, llin. wide, more or less glaucous or reddish, smooth, with 
about 3 primary nerves on each side ; spathes very narrow, 1 J in.
