middle. Lower floret almost as long as the glumes, reduced to an 
oblong acute hyaline 2-nerved ciliate valve. Upper floret slightly 
shorter than the lower : valve oblong, 2-fid to one-third, with the 
lobes oblong and subobtuse, 3-nerved, ciliate, awn fine, 4-8 lin. long, 
kneed at and twisted below the middle, column like the bristle 
scaberulous ; valvule linear-oblong, over 1| lin. long, obtuse, nerve- 
less, eciliate. Anthers 1| lin. long. Pedicelled spikelet $ , dorsally 
compressed, lanceolate, acuminate, 2J-2J lin. long ; lower glume 
thinly chartaceous, with 5 intracarinal nerves, tips acute, with or 
without a minute bristle ; upper glume and florets similar to those 
in the sessile spikelet, but the upper valve acute and awnless. — -

upper.

Var. Fyffei, Stapf. Culms densely tufted, with few barren innovation shoots ; 
leaf-sheaths not auricled ; ligules very short; blades soft, 3-5 in. by 1| lin., 
loosely hairy below, pubescent to subglabrous above, midrib very slender. 
Inflorescence as in var. fastigians or much more reduced, sometimes with only 
one 1-noded branch. Sessile and pedicelled spikelets exactly as in the type.

The specimens have almost the appearance of a tufted annual and may be in 
their first year. This and the station on the lake shore may also account for 
the softer leaves. The spikelets are in all their parts indistinguishable from 
those from West Africa. 
34. A. tumidulus, Stapf. Perennial, forming small tufts with 
very few slender innovations, 1J-3 ft. high. Culms very slender, 
simple, 2-4-noded, glabrous, smooth, internodes long-exserted. 
Leaf-sheaths terete, very tight, striate, smooth, glabrous, produced 
at the mouth into narrow acute auricles ; ligules scarious, adnate 
to the auricles of the sheath, 1 to over 1J lin. long, truncate ; blades 
very narrow, linear, tapering to a fine point, up to 4 in. by J-l lin., 
pale green or purple, glabrous or very sparingly hairy towards the 
base, scabrid or scaberulous on both sides and along the margins ; 
subtending leaf with a spathaceous sheath which soon becomes 
very narrow and convolute and a setaceous rudimentary blade. 
Peduncles finely filiform, striate, firm, imperfectly articulated and 
bearded at the tips. Racemes 2-nate, one sessile, the other or 
both with a short base, slender, rather dense, 1-2 in. long,
