34. CAPILLIPEDIUM, Stapf. 
Spikelets 2-nate, one sessile, the other pedicelled, similar in shape 
but differing in sex, in 1-2- (rarely up to 8-) jointed racemes at the 
ends of the capillary primary and secondary and often tertiary or 
even quaternary branches of a loose panicle ; joints and pedicels 
finely filiform, longitudinally grooved and hyaline in the groove, 
disarticulating horizontally ; sessile and pedicelled spikelets decidu- 
ous, the, former with the adjacent joint and pedicel. Florets 2 in the 
sessile spikelet, lower reduced to an empty valve or quite suppressed 
in the pedicelled spikelets, upper g ; 1 }( J or neuter, in the pedicelled 
spikelet. Sessile spikelet dorsally compressed, awned ; callus small, 
shortly bearded. Glumes equal, membranous to subherbaceous ; 
loker 2-keeled, with narrow indexed margins ; upper boat-shaped, 
3-nerved, keeled, grooved on both sides along the obtuse keel. Valve 
of lower floret hyaline, nerveless, of upper floret reduced to a hyaline, 
linear stipe, firmer upwards, passing into a slender awn. Valvule 0. 
Lodicules 2, minute, glabrous. Stamens 3. Stigmas exserted 
laterally, longer than the styles. Grain oblong-ellipsoid or oblong, 
dorsally slightly compressed ; embryo exceeding half the length of 
the grain. Pedicelled spikelet awnless, valve (if present) hyaline, 
nerveless. — Annual or perennial grasses with slender culms, simple 
or branched (sometimes very copiously), frequently bearded at 
the nodes. Leaf-blade with a rather conspicuous white midrib. 
Panicles delicate, when much divided the branchlets at length more 
or less divergent. Spikelets small. 
Species 6, in tropical and subtropical Asia, Polynesia and Australia, 1 extend- 
ing to tropical Africa. * 
1. C. parviflorum A Stapf. Perennial; innovation-shoots extra- 
vaginal, their cataphylls more or less hairy, at length glabrescent. 
Culms tufted, to over 3 ft. high, erect or shortly ascending at the base, 
simple or sparingly branched, terete, internodes sometimes channelled 
on the side facing the subtending leaf, glabrous. Leaf -sheaths 
terete, tight or at length slipping off the culms, the lowest longer,
