CLVii. GKAMiNEiE (Stapf). \Hyparrhenia. 
downwards rather distant about 3-rayed simple or (below) mixed 
tiers ; subtending leaves with usually well-developed blades, glabrous, 
green. Spatheoles linear-lanceolate, acutely acuminate, 1-1J in. 
long, glabrous or more or less hairy, early turning red ; rays sub- 
fastigiate, very slender, filiform, over 2 in. long ; peduncles laterally 
shortly exserted from the middle of the spatheole, permanently 
shorter than the same (up to J in. long, rarely longer), straight or 
more or less recurved, pubescent upwards and also beset with long 
tubercle-based white hairs for about 3 lin. below the tips. Kacemes 
somewhat diverging, at length epinasfcicallv deflexed, silkily greyish- 
villous, 7-10 lin. long, 6-8-awned per pair, bases very short, pubescent 
in the fork, upwards with a hirsute beard, tips oblique ; joints 
and pedicels filiform, slender, up to l\ lin. long with obliquely trun- 
cate tips, densely ciliate, cilia almost equally long throughout, 
| lin. long. Homogamous pair of spikelets 1 at the base of the lower 
raceme only. Fertile spikelets oblanceolate-oblong, up to 2J lin. 
long, greenish with a slight tinge of purple, callus short, subobtuse, 
| lin. long, beard hardly longer. Glumes equal, upper subchar- 
taceous, truncate, flat on the back, 7-9-nerved, pubescent at the 
base, then villous upwards with spreading tubercle-based hairs up 
to 1 J lin. long, margins narrowly involute, subterminal keels obscure ; 
upper glume submembranous, obliquely truncate in side view, 
3-nerved, shortly hairy on the back. Lower floret reduced to a 
linear-oblong obtuse hyaline 2-nerved ciliate valve. Upper floret 
^ : valve narrowly stipitate, passing into the awn which is about 
10-12 lin. long, kneed and often flexuous, column densely and 
finely fulvo- pubescent ; valvule a minute oblong scale hardly 
equalling the lodicules. Anthers J lin. long. Pedicelled spikelets 
lanceolate, about 3 lin. long, dull purplish ; glumes equal, lower 
subchartaceous, loosely villous all over, passing into a bristle 1-1-| 
lin. long, closely 11-13-nerved, upper membranous, very acute, 
3-nerved, ciliolate with a few hairs on the back ; valves slightly 
shorter than the glumes, hyaline, ciliolate, linear-oblong, the lower 
3-nerved, the upper 1-nerved and very narrow ; anthers 1 lin. long.

Kenia, 5000-10,000 ft., and designated by him “ Elephant grass,” evidently 
belongs here.
