auricled tips ; joints usually 2, slender, filiform, obliquely truncate, 
up to f lin. long, very shortly white ciliate ; pedicels very similar. 
Homogamous pair of spikelets 1 at the base of the lower raceme. 
Fertile spikelets lanceolate-oblong, including the callus 2J lin. long, 
greenish or tinged with brown or purple, scantily pubescent ; callus 
less than | lin. long, subacute, densely shortly bearded. Glumes 
equal, subchartaceous, the lower minutely truncate, flat on the back, 
loosely pubescent, 9-nerved, nerves evanescent below, margins 
involute for two-thirds, then indexed forming slender scaberulous 
keels ; upper glume obliquely truncate, 3-nerved, spreading!}' 
ciliate. Lower floret reduced to a linear-oblong delicately 2-nerved 
ciliate hyaline valve If lin. long. Upper floret ^ : valve stipi- 
tiform, 2-toothed, teeth less than J lin. long, lanceolate, ciliolate ; 
awn slender, 10-12 lin. long, pale brown, fulvously hispidulous. 
Anthers 1J lin. long. Fedicelled spikelets or frequently neuter, 
linear-lanceolate, often subaristulate, 2 b lin. long, reddish, glabrous 
or sparingly pubescent ; lower glume 9—1 1 -nerved ; keels spinulously 
ciliolate upwards, terminal bristle if present up to almost 1 lin. long ; 
lower glume thinner, shorter, 3-nerved, reversedly ciliate ; valves 
hyaline, the lower linear-oblong, 2 lin. long, 1 -nerved, reversedly 
ciliate or like the upper more or less reduced, often represented by 
a hyaline ciliate scale. Lower homogamous spikelet up to 3J lin. 
long, not aristulate. — Cymbopogon gazense, Rendle in Journ. Linn.

^ 3. H. dichroa^ Stapf , Perennial, apparently very tall, with [ { 
extravaginal innovations, their cataphylls firm, glabrous or sparingly 
hairy. Culms stout, to over 3 lin. in diam., terete or subterete, 
solid, glabrous, smooth, somewhat pruinose below, 4-5 (or more ?)- 
noded with vegetative (from the lower nodes) or mixed branchesx 
below the panicle. Leaf-sheaths of lower branches somewhat com- 
pressed and keeled, prominently nerved, of the culms terete, firm, 
all quite glabrous and very smooth, the basal decaying and break- 
ing away ; ligules very short, scarious, rounded or truncate, glabrous ; 
blades linear from an equally broad or slightly attenuated almost 
rounded base, tapering to a long fine point much over 1 ft. long, 
up to 5 and even 7 lin. wide, those of the culms firm and rigid below, 
of the vegetative branches thinner and softer, all flat, quite glabrous, 
rarely with some stiff tubercle-based hairs above the ligule, slightly 
rough above or smooth all over with the exception of the scabrid or 
epinulose margins ; midrib up to 1 lin. wide and whitish on the upper 
surface, very prominent below, primary lateral nerves up to 5 or 
more on each side in the widest leaves, prominent above. Spat heat e 
panicle very large, up to over 2 ft. long, decompound to the third .
