long ; anthers 3-3J lin. long. Homogamous spikelets similar to 
the pedicelled members of the trio, but up to 8 lin. long, more oblong, 
and broader ; their lower glume muticous, shortly acute, firmer, 
broader with narrow herbaceous wings and indexed flaps on both 
sides, unequally 9-nerved between the keels, valves slightly longer.

45. MON 0CYMBXUM, Stapf. 
Spikelets 2-nate, those of each pair differing in sex and structure 
otherwise alike in shape, one sessile, the other pedicelled on 
the articulate fragile rhachis of many- jointed solitary racemes, 
terminating the culms and their branches ; each raceme sup- 
ported by a spatheole and forming with it a monostachyum ; 
monostachya collected into loose spatheate panicles ; the fertile 
spikelets falling with the adjacent joint and the accompanying 
pedicel ; joints and pedicels finely filiform with truncate tips. 
Florets 2, lower reduced to an empty valve, upper ^ in the sessile 
spikelets, $ in the pedicelled. Sessile spikelets dorsally flattened 
with rounded sides, awned ; callus short and obtuse, indistinctly 
marked off from the lower glume, obscurely bearded. Glumes 
subequal, thinly cartilaginous, the lower obtuse, with narrow in- 
volute margins, not or very obscurely keeled near the tips, the upper 
boat-shaped, rounded on the back, laterally compressed and keeled 
in the upper third, usually aristulate, 3-nerved. Valve of the lower 
floret hyaline, ciliate, of the upper eciliate, deeply 2-fid with a hyaline 
base, margins and lobes, otherwise cartilaginous, eciliate, delicately 
awned from between the lobes. Valvule 0. Lodicules 2, minute, 
cuneiform, glabrous. Stamens 3. Stigmas laterally exserted ; 
styles terminal. Grain oblong, dorsally slightly compressed ; embryo
