long ; pedicels filiform, shortly ciliate, up to 2 \ lin. long. Homo- 
gamous pair of spikelets 1 at the base of the lower raceme 
only. Fertile spikelets oblong, flattened on the back or very 
slightly depressed along the middle, broadly rounded on the 
sides, including the callus 4-4 J lin. long, pale greenish, reddish 
towards the tips, pubescent ; callus slender, very acute, 1J lin. 
long, densely bearded, hairs whitish, the upper exceeding the callus 
by its own length. Glumes equal, chartaceous ; lower narrowly 
truncate, about 9-nerved, nerves faint downwards, margins involute, 
keels fine, short, minutely and rigidly ciliolate ; upper glume deltoid- 
acute, deeply grooved along the broad keel, ciliate upwards. Lower 
floret reduced to an oblong acute 2 -nerved hyaline r e vers edly ciliate 
valve, over 2J lin. long. Upper floret ^ : valve stipitiform, with 
a hyaline margin and 2 small teeth ; awn rather stout, to over 3 in. 
long, fulvously hirtellous ; valvule 0. Anthers up to 2 lin. long. 
Pedicelled spikelets linear -lanceolate, very acute, 5-6 lin. long, 
glabrous, greenish or pale reddish ; lower glume with or without 
a terminal bristle, up to 6 lin. long, very closely and finely many- 
nerved, keels rigidly ciliolate; upper glume membranous, acute,

small groups, Schweinfurth, 1034 ! 
Schweinfurth’s specimen quoted under var. pellita may be a distinct species, 
the peduncles are much shorter than the spatheoles, and this in combination 
with the long silvery hairs of the fertile spikelets gives it a peculiar appearance, 
but the specimens seen are young plants, and it is quite possible that the 
peduncles ultimately grow out as much as in the typical form ; all other cha- 
racters agree very well with H. confinis . The length of the appendage of the 
raceme-bases differs in the specimen referred here to typical H. confinis, the 
extremes being 1 lin. (in the specimen from the Belgian Congo), or less than 
| lin. (in some of those from the Oubangui Territory).
