720 clvii. gramine^j '(Stapf). [ Panicum . 
Leaf-sheaths tight, terete or the lowest subterete, very closely and 
prominently striate, tomentose at the nodes, the basal otherwise 
more or less densely pubescent, the upper less so to subglabrous with 
short clavellate gland-tipped hairs among the finer and acute hairs, 
or the latter absent ; ligule a ciliolate rim ; blades linear from an 
equally wide base, gradually tapering to a subacute slightly callous 
point, up to 3 in. by 1-2 lin., flat or the basal setaceously convolute, 
green, somewhat thickly herbaceous, loosely pubescent on both sides, 
hairs white, fine, here and there intermixed with a few gland-tipped 
clavellate hairs, margins scabrid, midrib and nerves very fine and close. 
Panicle erect or slightly nodding, open and then obovate and very 
loose or more or less contracted, 3-5 in. long, divided to the third 
degree, bearing on the common axis and all or most of its divisions 
spreading hairs with clavellate glandular tips, more rarely glabrous 
upwards ; common axis filiform, terete, slightly striate, smooth, 
glabrous except for the gland-tipped hairs, or shortly pubescent 
downwards, lower internodes J-f lin. long ; primary branches finely 
filiform to flexuous, very loosely divided from the base or near it, 
terete, smooth, the longest up to over 3 in. long, scantily and distantly 
divided from the base, lowest branchlets up to 1 in. long ; pedicels 
very unequal, 1J-6 lin. long, very flexuous, with gland-tipped hairs 
only or quite glabrous, slightly thickened towards the subdiscoid 
tips. Spikelets oblong, subacute or obtuse, slightly dorsally com- 
pressed, If to almost 2 lin. long, green or tinged with purple, glabrous. 
Glumes unequal, membranous, finely prominently nerved, dentate ; 
lower broadly ovate, one-third to almost half the length of the 
upper floret, 3-4-nerved, with the nerves running into as many narrow 
acute subterminal teeth ; upper broadly oblong, equalling about 
three-quarters of the spikelet, 5-nerved and shortly and very 
acutely 5-toothed, with few delicate transverse nerves. Lower 
floret barren, reduced to a valve which is lanceolate in profile and 
oblong in back view, with a blunt minutely 3-toothed top and as 
long as the fertile floret, nerves 7 with few transverse venules 
upwards. Upper floret oblong or lanceolate-oblong, subobtuse, 
whitish ; valve and valvule thinly papery, the valve softly pubescent 
near the tip ; anthers 1 lin. long. — K. Schum. in Engl. Pfl. Ost-Afr.
