Pedicelled spikelet $ or neuter ( Hackel ), lanceolate, acuminate, 
3J lin. long, shortly hairy ; lower glume rather flat, 2-keeled, minutely 
2-toothed with a short bristle, shortly hairy below, often purplish 
upwards, intracarinal nerves numerous ; upper glume lanceolate- 
oblong, subhyaline, 3-nerved, eciliate. Valve of lower floret 
as in the sessile spikelet, but narrower. Valve of upper floret 
entire, oblong-lanceolate, acute, almost 3 lin. long, 3-nerved, 
ciliolate, awnless. Anthers 2 lin. long. — Androjpogon Jeffrey sii ,

Hackel describes the leaves as remotely spinulous ; in the case of Roger’s 
plant this is only true of the upper margins of some of the leaves, the margins 
as a rule being uniformly scabrid.

^ 12. S. SchweinfurthivStep/. Culms over 2 ft. high, terete, simple 
for the first 3 or 4 nodes, then giving off flowering branches, smooth, 
glabrous. Leaf-sheaths (the basal ones unknown) terete, striate, 
glabrous ; blades narrowly linear, tapering to a long fine point, up 
to 8 in. long by almost 1J lin. wide (when flat), rigid, pale green, 
more or less loosely hairy on both sides or glabrescent, margins 
scabrid, midrib slender, prominent below, primary lateral nerves 
2- 3 on each side, somewhat raised. Inflorescence made up of few 
to many flowering branches, rising solitary or in pairs from the upper 
nodes, simple or divided once again, ultimate divisions 1- or 2-noded, 
filiform, erect or suberect, the lower J to almost 1 ft. long ; spathes 
very narrow, up to 2 in. long, glabrous, with a short setaceous scabrid 
and sometimes sparingly hairy blade ; peduncles very slender, more 
or less exserted from the spathe, tips very slightly thickened, ending 
with a small oblique cupule. Racemes 1J to over 2 in. long, up to 
2 lin. wide, very dense and almost glabrous, green tinged with purple- 
brown, 16-20-jointed ; joints 1J lin. long, linear, slightly widened 
upwards, somewhat curved, glabrous or ciliate on the outer angle, 
tips with a very shallow unequally 2-toothed cupule ; pedicels 
linear, up to If lin. long, glabrous, or ciliate along the outer angle. 
Sessile spikelet including the short broad minutely bearded callus 
3 lin. long, lanceolate, acuminate, greenish up to the middle, then 
purplish-brown. Glumes subequal ; lower thinly chartaceous, 
acute or obscurely 2-dentate, almost flat on the back, glabrous and 
smooth, inflexed margins very narrow, keels scabrid upwards, 
intracarinal nerves 5, faint ; upper glume boat-shaped, subgibbous, 
produced into a long fine acumen or a short bristle, membranous, 
3- nerved, scabrid on the keel, ciliolate. Lower floret reduced to a 
hyaline oblong faintly 2-nerved ciliolate valve, 2J lin. long. Upper
