clvii. GRAMINE^ (Stapf). [( Cymbopogon . 
and sometimes rounded base, long-tapering to a fine point, to over 
1 ft. long and J to over 1 in. wide, glaucous, glabrous, smooth except 
on the upper margins ; midrib rather slender, primary lateral 
nerves 7-11 on each side, fine, slightly raised. Spatheate panicle 
very dense to quite compact, ovoid to oblong or subglobose, 3J to 
over 6 in. by 2J-4 in. ; lowest internodes 1-2J in. long, the following 
rapidly decreasing ; lowest primary branches undivided at the 
base with the first internode as long as or slightly shorter than the 
subtending sheath, like the following repeatedly divided above it, 
their divisions forming much contracted mixed tiers, those of the 
last order usually 4-2-rayed ; rays finely filiform, 2-1 \ lin. long, 
glabrous ; subtending sheaths with normal but shorter blades ; 
spathes lanceolate, acutely and often finely acuminate, thinly 
subherbaceous, 6-8 lin. long, green, then turning reddish or brownish. 
Spatheoles similar but scarious, narrower and somewhat shorter ; 
peduncles 2-1 \ lin. long, very slender, glabrous. Racemes 2-nate, 
slender, olive-green to brownish, 4-7 lin. long, obscurely hairy, 
one sessile or subsessile, the other with a glabrous base up to f lin. 
long ; joints linear, very slender, 1 lin. long, glabrous on the back, 
very shortly ciliate except for a few cilia about 1 lin. long below the 
tips, tips obliquely auriculate, cupular, auricles very broad ; lowest 
joint of sessile raceme much shorter andjstout ; pedicels very similar, 
the lowest of the sessile raceme short but very slightly stouter, free 
from the adjacent joint and eciliate. Homogamous pair 1 at the 
base of the sessile raceme. Fertile spikelets oblong, subobtuse, 
1J lin. long, glabrous ; callus very small, obtuse, minutely bearded. 
Glumes subchartaceous, equal ; lower subtruncate, flat on the back, 
with a fine or obscure median groove, keels acute or very obscurely 
winged ; intracarinal nerves and oil-streaks one on each side of the 
groove, the former usually very delicate, the latter fusing in the tip, 
usually obscure, unless at length turning brown ; upper glume narrow 
in profile, acutely keeled above, 1-nerved. Lower floret reduced 
to an oblong obtuse sub-2-nerved sparingly ciliolate valve. Upper 
floret ^ : valve reduced to a subchartaceous extremely slender 
stipe usually without any lobes and passing gradually into a fine 
bristle, including it 2J lin. long. Anthers § lin. long. Pedicelled 
spikelets neuter, lanceolate to lanceolate-oblong, 1J lin. long ; lower 
glume subherbaceous with 5-3 intracarinal nerves ; upper mem- 
branous, white, 1- to sub-3-nerved ; florets usually quite suppressed.
