short scaberulous keels, sparingly to copiously hairy all over the 
back ; nerves 9, the 3 inner rather distant, the others very fine and 
rather close ; upper glume sub membranous, obtuse or emarginate, 
3-nerved, ciliate above. Lower floret reduced to an oblong obtuse 
obscurely 2-nerved and reversedly ciliate valve. Upper floret ^ : 
valve substipitiform, minutely 2-toothed ; awn § to almost 1 J in. long, 
rich brown, column shortly hirsute. Anthers 1-1J lin. long. Grain 
obovate, flat on the back, very concave in front above the middle ; 
embryo half the length of the grain. Pedicelled spikelets linear- 
Janceolate or linear-oblong, 2J-3 lin. long, like the sessile spikelets 
in colour and hairiness : glumes acute, firm, the upper 7-nerved, 
the lower 3-nerved ; valves hyaline, oblanceolate to (the upper)

Andropogon rufus, var. auricoma, Pilger in Engl. Jahrb. xxx. 268, from the 
Ukinga Mountains in German Nyasaland ( Goetze , 901), evidently belongs here. 
It has the same woolly tomentum at the base of the lowest sheaths and shaggy 
beards at the junction of sheath and blade, but it is a taller plant with the 
lower culm-leaves up to 15 in. long and 2| lin. broad, and traversed by a stout 
midrib. The cilia are white at the callus and the bases of the joints and pedicels, 
and fulvous upwards, much as in H. rufa, but are rather longer. 
11. H. smithiana^ Stapf. Perennial, about 2 ft. high, tufted^ 
innovations intravagmal. Culms erect, moderately slender, glabrous 
and smooth, simple and 2-3-noded below the panicle. Leaf- 
sheaths terete or slightly keeled upwards, the lowermost more or 
less persistent, hairy all along, the next hairy upwards only or 
glabrous, hairs often scanty ; ligules scarious, truncate or rounded, 
up to over 1 lin. long, often hairy from behind ; blades linear from 
a gradually attenuated base, tapering to an acute point, 6-10 in. by 
1J-2J lin., somewhat rigid, suberect, flat, pale green, glabrous, . 
rough along the margins ; midrib stout in the lower, slender in 
the upper leaves, primary lateral nerves about 3 on each side, 
slender. Spatheate panicle elongated, scanty or moderately com- 
pound, lax, about 1 ft. long, of up to 4 distant few- to 5-rayed tiers, 
the lowest tiers often mixed, consisting of a simple and a compound 
2-3-noded ray or all the tiers reduced to a single ray ; simple rays 
slender, 1J-2J in. long ; subtending leaves with generally well
