1. A. glabra, Stapf. Perennial ; rhizome very short, hard, inno- 
vations extravaginal, cataphvlls ovate to lanceolate, acute, hard, 
smooth. Culms tufted, erect or shortly ascending, to over 3 ft. high, 
terete, rather stout below, glabrous, 5-7-noded, simple or very 
sparingly branched. Leaf-sheaths terete, glabrous, smooth, the 
intermediate and upper mostly shorter than the internodes, nodes 
glabrous or the upper bearded ; ligules truncate, very short, seari- 
ous ; blades linear, long-tapering to a setaceous point, hardly broader, 
not or slightly contracted at the base, up to over 1 ft. by 4 lin. (mostly 
narrower), pale green, often turning reddish or purplish, glabrous, 
rarely with very fine long spreading white hairs at and above the 
ligule, smooth except at the margins, midrib rather stout to very 
stout downwards, lateral nerves 3-4 on each side. Panicle narrowly 
oblong, 4-9 by 1-1 \ in., erect, primary axis much longer than the 
lowest racemes, somewhat stout and (at least when mature) stiff, 
smooth, shortly bearded at the branch axils, otherwise glabrous and 
smooth ; branches whorled, up to 6 in a whorl or semiverticillate, or 
2- nate or solitary from the weaker nodes, straight, 1-3 in. long, the 
longer divided from J in. above the base, few- to 7-noded, secondary 
branches simple. Racemes -J-1J in. long, straight or flexuous, 
usually purplish, inconspicuously white-villous ; joints and pedicels 
1-1 J lin. long, ciliate, uppermost cilia much longer than the rest, up 
to J lin. long. Sessile spikelet pale green or purplish throughout, 
including the small minutely bearded callus lf-l§ lin. long. Glumes 
equal; lower truncate, slightly concave on the back, chartaceous- 
membranous, hairy below the middle, more rarely glabrous, keels 
rigidly ciliolate upwards, intracarinal nerves 4-5, very fine, evanes- 
cent upwards with (always in the African specimens) or without a 
pit above the middle ; upper glume lanceolate, acute, 3-nerved, keel 
scabrid upwards, margins sparingly ciliate. Valve of lower floret 
oblong, 1J lin. long, hyaline, nerveless, ciliate ; awn of upper floret 
3- 6 lin. long, brown below, pale above the bend. Pedicelled spikelet 
neuter, mostly reduced to the glumes, narrowly linear-oblong to 
linear, 1J-1J lin. long, glabrous, of the same colour as the sessile. 
Lower glume rigidly and minutely ciliolate, 5-9-nerved, often rolled 
in, not pitted, upper hyaline, nerveless, often minute. — Andropogon
