nerve on each side near the margin. Lower floret reduced to a deli- 
cate oblong minutely truncate ciliolate nerveless valve. Upper 
floret ^ ; valve substipitiform, almost lin. long, 2-fid to the middle, 
segments subulate, ciliolate ; awn very fine, 5-7 lin. long, bent at 
and twisted below the middle. Anthers almost 1 lin. long. Pedi-

green, glabrous ; lower glume slightly convex on the back, sub- 
herbaceous, about 10-nerved, the inner 6 nerves prominent ; upper 
subhyaline, 3-nerved ; valve oblong, truncate, sub-2-nerved, almost

14. C. giganteus, Chiov. Gram, da Essenze , 12. Perennial, with ex- 
travaginal innovations from a short rhizome, up to 8 ft. high. Culms 
somewhat robust, up to 3 lin. in diam., many-noded and simple below 
the panicle, glabrous, smooth, intermediate and upper internodes ex- 
serted. Leaf-sheaths terete, moderately firm or the lower rather thin 
and decaying leaving the culm-bases bare, glabrous, smooth, green or 
glaucous and waxy at the nodes ; ligules almost reduced to a rim or 
up to 14 lin. long, scarious, glabrous ; blades linear from a rounded 
broader base, long-tapering to a fine point, up to over 1 ft. long and 
(at the base) to 1 in. or more wide, rigid, glaucous, glabrous, smooth 
except on the rough margins ; midrib slender, primary lateral nerves 
numerous, slightly raised on both sides. Spatheate panicle narrow- 
linear to oblong in outline, more or less decompound, frequently 
over 1 ft. long, interrupted ox rather dense throughout, internodes 
numerous, lowest 4-6 in. long, upper rapidly decreasing ; lower 
primary branches usually undivided below with the first internode 
exserted from the supporting sheath, then many-noded, often very 
long and repeatedly divided, upper gradually shorter, forming 
oblong mixed tiers; ultimate tiers of usually 2 rays 4-5 lin. long, 
glabrous ; lower subtending leaves with well-developed though shorter 
blades; spathes lanceolate, subherbaceous, 1-4 in. long, acutely 
acuminate, glaucous. Spatheoles very narrow, acuminate or acute, 
7-9 lin. long, greenish turning straw-coloured or reddish ; ped- 
uncles 2J-3 lin. long, obscurely puberulous below the subcup ular 
tips or glabrous. Racemes 2-nate, more or less diverging and at length 
epinastically deflexed, one subsessile, the other with a short pubescent 
or ciliate bare base, J-f lin. long ; base of the subsessile raceme and 
adjacent pedicel short, hard, swollen and fused; fertile joints 
linear, 1J-1J lin. long, glabrous on the back and densely ciliate, 
cilia up to over 1 lin. long ; adjacent pedicels very similar.
