hairs at the nodes. Leaf-sheaths very firm, smooth, glabrous, 
tight, those of the innovations and base of the culms widened at 
the base, very tough and long-persistent, straw-coloured, up to 5 in. 
long ; li gules membranous to scarious, oblong, truncate, ciliate, 
up to 1 J lin. long ; blades semiterete, filiform, wiry, flexuous, very 
fine and often circinate upwards, rounded on the back, channelled 
on the face, or those of the culms somewhat flatter and shorter, up 
to more than 9 in. long, J lin. in diam., glabrous, finely scaberulous 
on the nerves below, though often smooth to the touch, pale, glau- 
cous, evenly 7-9-nerved, the midrib showing only above as a broad 
white band. Spatheate panicle narrow, 3-12 in. long, few- to 7- 
noded, lower internodes 2-3 in. long, upper rapidly decreasing in 
length, slender, glabrous ; lowest primary branch rarely undivided 
at the base, 3-2-noded and up to 6 in. long, usually forming — like 
the following— up to 4-rayed simple or mixed tiers ; lowest sub- 
tending sheaths with foliaceous blades ; rays finely filiform, 1-1J 
(rarely to over 2) in. long, glabrous ; spathes narrowly lanceolate, 
subherbaceous, often tinged with pale purple, with a short blade 
or the upper bladeless and produced into a setaceous point, lj-lfin. 
long, glabrous. Spatheoles very narrow, acute or with a setaceous 
point J-l in. long, pale or straw-coloured ; peduncles finely filiform, 
widened upwards, 1J-2 lin. long, tips truncate. Racemes 2-nate, 
more or less divaricate, at length epinastically deflexed, J-l lin. 
long, white- villous, pale or tinged with purple, one subsessile, the 
other with a bare base, J-l lin. long ; bases puberulous to pubescent 
in the fork, ciliate-bearded upwards, with minutely cupular and 
denticulate tips, that of the subsessile raceme as well as the adjacent 
pedicel stout, elliptic to elliptic-oblong in outline and convex on the 
back, ultimately more or less glabrescent and glossy; fertile joints 
filiform, slightly widened towards the oblique subcupular auricled 
tips, 1J-1J lin. long, densely hairy to villous from the back and 
the angles (hairs increasing upwards to 2 lin. long) ; adjacent 
pedicels similar to the joints but more slender. Homogamous 
pair of spikelets 1 at the base of the sessile or of both racemes ; the 
sessile spikelet of the lowest but one of the sessile raceme inter- 
mediate and imperfectly awned. Fertile spikelets linear-lanceo- 
late, more or less acuminate, acute, including the callus 2 J-3 or even 
3J lin. long, glabrous, pale green below, reddish upwards ; callus short, 
obtuse, shortly bearded. Griumes equal, chartaceous ; lower nerve- 
less and shallowly concave between the acute scaberulous keels, 
minutely 2-denticulate ; upper lanceolate-oblong in profile, acute, 
slightly curved on the back, 1 -nerved, margins broadly hyaline up- 
wards, ciliate. Low r er floret reduced to a linear-oblong nerveless 
hyaline ciliolate valve, slightly shorter than the glumes. Upper 
floret 3 : valve very narrow, shortly 2-fid, cuneate-linear and char- 
taceous below the insertion of the awn, under 1J lin. long, lobes 
broadly lanceolate, ciliate ; awn up to 5 lin. long, very fine, more or
