CLYII. GRAMINE2E (Stapf). 
[Acritochcete. 
with scabrid margins ; midrib pale, primary lateral nerves 3 on 
each side. Racemes dense, distant by less than their own length, 
erect and appressed to the common axis, the whole inflorescence up 
to 4 in. long ; rhachis very slender, straight or flexuous, glabrous, 
terete or sulcate on the face ; pedicels terete, the lower up to 1 lin. 
long. Spikelets whitish-glaucous, 3 lin,. long (excluding the awns). 
Lower glume truncate, nerveless, up to § lin. long, sometimes obso- 
lete ; upper lanceolate, embracing the barren floret with its rounded 
base but narrower upwards than it, 2 lin. long, with few white bristles, 
awn very fine, up to 14 lin. long, scabrid at the base, minutely setu- 
lose towards the tips. Lower floret : valve lanceolate, 3 lin. long, 
embracing the upper floret with its inflexed margins, with some 
whitish bristles from the back, awn similar to that of the upper glume 
but rather shorter, usually entangled with it and other awns. Upper 
floret slightly shorter than the lower : valve ovate-lanceolate, 
acute, almost colourless, smooth, glabrous, middle nerve green, 
rather prominent, side-nerves approximate ; valvule thin, acute, 
as long as broad. Anthers stout. Stigmas whitish.

I have not seen a specimen of this remarkable plant and am altogether 
doubtful as to its true affinities. Pilger also says that he cannot see a distinct 
relationship between Acritochcete and the small genera grouping around Panicum, 
but that Hackel thought it most nearly allied to Chcelium.

Herb. xii. 210. 
Spikelets ovate or elliptic to lanceolate-oblong, acute or acuminate, 
mostly awned, slightly or conspicuously compressed from the back, 
falling entire from the pedicels, 2-nate or fascicled, subsecund and 
abaxial on the triquetrous rhachis of more or less spiciform digitate 
or subdigitate racemes ; lower floret usually upper floret 
Glumes unequal, lower smaller, membranous to hyaline, 3-1 -nerved, 
very acute, often mucronulate, upper equal or subequal to the 
spikelet, membranous to chartaceous, 5 -nerved with the outer nerves 
submarginal, densely ciliate along them. Lower floret : valve 
resembling the upper glume, but eciliate, the tip minutely truncate 
and the lateral nerves approximate to each other and in or near the 
marginal flexure ; valvule short, deeply 2-fid with conspicuously 
auricled flaps. Upper floret : valve chartaceous, glabrous, deli- 
cately ciliolate upwards, 5-nerved, produced into a straight awn 
or mucronate ; valvule equal to the valve, 2-keeled, with broadly 
auricled flaps. Lodicules 2, broadly cuneate. Stamens 3. Styles 
distinct ; stigmas laterally exserted. Grain enclosed by the valve 
and valvule, elliptic- oblong, dorsally much compressed ; scutellum 
about half the length of the grain ; hilum basal, punctiform. —
