clvii. gramine^ (Stapf). [ Hyparrhenia . 
mostly recurved in a semicircle, pubescent upwards, tbe curvature 
beset with stiff spreading tubercle-based whitish hairs up to 3 lin. 
long. Racemes somewhat diverging, rarely at right angles, at 
length epinastically reflexed, more or less silky villous, 8-14 lin. 
long, 7-15-awned per pair ; bases very short, pubescent in the fork, 
upwards hirsute, tips with a minute dark auricle ; joints and pedicels 
filiform, slender, almost 1J lin. long, with obliquely truncate tips, 
densely ciliate, cilia up to 1 lin. long. Homogamous pair of spikelets 
1 at the base of the lower raceme only. Fertile spikelets linear- 
oblong to linear-lanceolate, 2J-2§ lin. long, pale below, reddish 
upwards : callus very short, subobtuse to almost acute, beard dense, 
white, J-J lin. long. Glumes equal, lower subchartaceous, minutely 
truncate, flat on the back, thinner downwards, 7-9-nerved, loosely 
to densely whitish-villous upwards, margins subinflexed upwards, 
rigidly ciliate along the subterminal keels ; upper glume thinner, 
submembranous, subtruncate, 3-nerved, hairy along the keel. 
Lower floret reduced to a linear-oblong subobtuse hyaline 2-nerved 
ciliolate valve, almost as long as the glumes. Upper floret ^ : valve 
stipitate, 1 J lin. long, with two short glabrous subacute lobes ; awn 
slender, 8-12 lin. long, with the column fulvously or rufously hir- 
tellous ; valvule 0. Anthers over £ lin. long. Grain elliptic-oblong, 
dorsally much compressed, 1 J lin. long ; embryo half as long. 
Pedicelled spikelets lanceolate-oblong, acute, muticous, 2J-3J lin. 
long ; glumes equal, hairy, the lower about 9-nerved, upper 3- 
nerved ; valves slightly shorter than the glumes, membranous to 
hyaline, linear-oblong to linear, ciliolate, the lower 3-, the upper, 
which is very narrow, 1-nerved ; anthers 1J lin. long. — Andropogon

34. H. arrhenobasis A Stapf. Perennial, up to over 3 ft. high, 
densely tufted with extravaginal innovations, shoots close to the 
flowering culms. Culms erect or geniculately ascending, simple 
and 4-5-noded below the panicle, moderately stout, terete or 
somewhat compressed below, glabrous, smooth. Leaf-sheaths 
terete or the lowest slightly compressed and keeled, glabrous 
or rarely sparingly hirsute upwards, those of the innovation shoots 
1-2 in. long ; ligules scarious, rounded or truncate, very short, 
glabrous or sparingly hairy ; blades linear from an equally wide 
base, tapering to an acute point, the cauline J-1J ft. long, 2-4 lin. 
wide, of the innovations usually much shorter, somewhat firm but 
hardly rigid, pale green, glabrous or with a few tubercle-based 
hairs towards the base, scabrid along the margins, otherwise almost 
smooth. Inflorescence a narrow scanty panicle rarely over 1 ft.
