long, of 4-5 distant few-rayed tiers or simple branches ; subtending 
leaves or spathes resembling the preceding leaves, with mostly 
well-developed blades or the upper spatheoloid ; rays simple or (in 
strong specimens) one of the lowest tiers compound, 2-3-noded, 
filiform, 2-3J in. long. Spatheoles lanceolate, acuminate, 2-2J in. 
by 2-2 J lin., scarious, green, tinged with red or reddish, glabrous, 
permanently boat-shaped with ultimately inr oiled margins, rarely 
altogether inrolled. Peduncles at length up to 1-1 £ in. long, arched 
upwards, with a long beard of stiff tubercle-based white or yellowish 
hairs from the curvature, the bearded tips laterally or subterminaJly 
exserted from the spatheoles. Racemes subcontiguous, usually 
nodding, at length epinastically reflexed (?), f-1 in. long, 7-12-awned 
per pair, rather stout, yellowish or brownish green; bases short, 
from less than J to 1 lin. long, with long stiff spreading tubercle-based 
hairs ; joints slender, filiform, 1 lin. long, obliquely truncate, shortly 
ciliate ; pedicels similar, up to 1J lin. long. Homogamous pair of 
spikelets 1 or 2 at the base of each raceme, supporting them like 
an involucre. Fertile spikelets linear-oblong, 3 lin. long including 
the callus, yellowish- green to brownish or purplish-brown ; callus 
short, up to f lin. long, subacute, bearded. Glumes equal, char- 
taceous to subchartaceous, lower flat on the back, sparingly and 
minutely pubescent, 9-nerved, intracarinal nerves somewhat raised 
all along; margins narrowly involute, inflexed towards the tips, 
the short keels rigidly ciliolate ; upper glume obliquely truncate, 
mucronulate, 3-nerved, more or less grooved between the nerves, 
with a broad rounded keel, margins erect, ciliate upwards. Lower 
floret reduced to an oblong or oblong-cuneate faintly 2-nerved 
hyaline valve 2J lin. long, sparingly ciliolate upwards. Upper 
floret § : valve stipitiform, 2-dentate, teeth almost \ lin. long, 
ciliate ; awn 1-1 \ in. long, fulvous, column hirtellous ; valvule 
an elliptic-oblong glabrous hyaline scale, \ lin. long. Anthers over 
1 lin. long. Pedicelled spikelets narrowly lanceolate-acuminate, 
up to 4 lin. long, glabrous ; lower glume chartaceous, produced 
into a mucro or very short bristle, spinulously ciliate along the keels, 
up to 13-nerved ; upper glume membranous, very acute to mucro- 
nulate, 3-nerved, sparingly ciliate, cilia erect ; valves hyaline, oblong, 
the lower 3 lin. long, sub-3-nerved, ciliolate, cilia erect, short ; upper 
valve oblanceolate-cuneate, emarginate, 1-nerved, otherwise like the 
lower; anthers If lin. long. — Heteropogon arrhenobasis , Anderss. in
