Culms in compact fascicles, erect, simple, wiry ; basal sheaths 
more persistent than in the two preceding species; blades 
6-10 mm. wide, somewhat firm, rich green above, glaucescent 
below, often suffused with purple near the base and along ~ 
the edges; panicle stiff, dense, 6-10 cm. long; spathes more 
herbaceous than in the other species, often with rudimentary 
blades, purplish-brown with yellowish scarious edges; spike- 
lets usually green in the lower, purple in the upper part 
10. C. polyneuros. 
VETIVERIA.—Racemes panicled, peduncled, very slender, many- 
jointed, in copious whorls on the nodes of an often long rhachis ; 
joints and pedicels filiform, glabrous or nearly so; spikelets 
laterally or dorsally slightly compressed; the sessile all alike, 
awned or awnless ; first (outer) glume muricate or smooth. 
Innovations forming dense, compressed bunches of leaves 
with equitant sheaths and keeled, fat (almost spongy) blades 
which are more or less V-shaped in cross section ; spikelets
