forming 2-3-rayed tiers or the lowest undivided at the base, 2-noded 
and up to 1 J ft. long, compound rays if present 2-1-noded ; simple 
rays 3 (the lowest)-l| in. long ; subtending leaves like the preceding 
ones, the uppermost with only slightly inflated spathes and with 
distinct though very narrow blades reaching to the top of the 
panicle. Spatheoles very narrowly linear, acuminate, 1J-1J in. 
by £ lin., scarious, glabrous, dull reddish, at length involute from 
the margins ; peduncles finely filiform, flexuous, glabrous, at length 
as long as or nearly as long as the spatheole. Racemes slightly 
diverging, slender, rather loose, about 1 in. long, 4-5-awned per pair, 
brownish-reddish ; bases linear-filiform, glabrous, the lower 1, the 
upper 2-2 \ lin. long, produced into a reddish oblong 2-denticulate or 
subentire scarious appendage \ lin. long, joints and pedicels very 
slender, filiform, about 2 lin. long, very shortly ciliate. Homogamous 
pair of spikelets 1 at the base of the lower raceme only. Fertile 
spikelets lanceolate-oblong, acuminate, 3J lin. long including the 
callus, glabrous, reddish at least upwards, callus J-J lin. long, obtuse, 
blackish with a short white beard. Glumes equal, chartaeeous ; 
the lower rather rigid, 2-denticulate, somewhat flattened on the back, 
rounded on the sides, slightly longitudinally grooved, with the 
middle nerve in the groove and the inner lateral nerves prominently 
raised, hence markedly ribbed, altogether 9-nerved, margins involute, 
keels short, scaberulous ; upper glume truncate and minutely 
apiculate, 3-nerved, obscurely ciliolate. Lower floret reduced to a 
lanceolate-oblong minutely truncate 2-nerved reversedly ciliate 
valve over 2| lin. long. Upper floret ^ : valve oblanceolate, 
cuneate, 2 J lin. long, 2-fid, very slender, hyaline and faintly 3-nerved 
up to the middle, then cartilaginous with a hyaline margin which 
widens upwards and passes into the lanceolate-oblong lobes J lin. 
long ; awn slender, 9-10 lin. long, bent at and twisted below 
the middle, column brown, minutely hirtellous, bristle pale ; val- 
vule an elliptic-oblong obtuse hyaline scale up to J lin. long. Anthers 
lj lin. long. Pedicelled spikelets narrowly linear-lanceolate, 
up to 4J lin. long, reddish, glabrous ; lower glume drawn out into a 
fine point, 11-nerved, the innermost side-nerves somewhat distant 
from the next outer, keels scaberulous ; upper glume somewhat 
shorter, very acute, 3-nerved, sparingly ciliate ; valves hyaline, 
reversedly ciliate, the lower cuneate-oblong, acute, 3-nerved, up to 
3J lin. long, the upper narrowly oblanceolate, shorter, 1-nerved ; 
anthers lin. long. Homogamous spikelets like the pedicelled. —
