in the pedicelled. Sessile spikelets snbterete or when mature 
quite terete, rarely distinctly compressed from the back when in 
flower ; callus short or more or less elongated and very acute, 
shortly bearded. Glumes subequal, coriaceous to subcoriaceous 
downwards ; the lower 2-dentate or 2-mucronate with involute 
margins up to two-thirds or more, then finely keeled, the upper 
boat-shaped, rounded on the back, keeled, usually minutely emar- 
ginate and with a fine bristle from the notch, 3-nerved. Valve of 
lower floret hyaline, ciliate, of upper eciliate, more or less 2-fid, 
with the base, margins and lobes hyaline, awned from between the 
lobes, awn distinctly differentiated into column and bristle. Lodi- 
cules 2, minute, glabrous. Stamens 3. Stigmas laterally exserted ; 
styles terminal, united at the base. Grain subterete to terete, 
shortly beaked from the persistent style-base ; scutellum half the 
length of the grain. Pedicelled spikelets similar in outline to the 
sessile, but acuminate and usually somewhat longer, often with an 
elongated callus ; lower glume with or without a terminal bristle, 
upper always muticous. Valves of both florets developed, hyaline, 
rarely the upper suppressed. — Perennial (? always) grasses with 
narrow blades and narrow stiff and contracted or open and more or 
less flaccid spatheate panicles. 
Species 9, endemic in West Africa. 
* Upper glume of sessile spikelet aristulate ; awn of fertile 
floret 4-18 (rarely 21) lin. long. 
Racemes reduced to a single pair of spikelets ; panicle 
decompound, lax and flaccid ; upper simple rays 
6-3 lin. long ; peduncle at maturity shorter (4-44 
lin. long) than the spatheole ; spikelets small 
(sessile 2 lin., pedicelled up to 3 lin. long) ; awn 
of fertile floret 10 lin. long .. . ... ... ... 1. A. trepidaria. 
Racemes of 1-5 sessile and as many (or more by 1 ) pedi- 
celled spikelets (or empty pedicels) ; if only 1 
sessile spikelet then the peduncle more or less 
(often far) exserted from the spatheole. 
tSessile spikelets 2-24 lin., pedicelled 2-3 lin. long ; 
awn of fertile floret 4-7 lin. long. 
Sessile spikelets glabrous and glossy except on 
the callus and acumen ; simple rays 6-12 lin. 
long ; spatheoles 7-10 lin. long. 
Peduncles at maturity more or less exserted 
terminally from the spatheole ; racemes 
with 1-4 sessile spikelets. 
Panicle decompound, lax and flaccid ; rays 
and peduncles capillary or almost so, the 
latter 10-16 lin. long ; awn 4-6 lin. long, 
pale brown, almost concolorous ; blades 
of upper leaves 2-2^ lin. wide, slightly 
contracted and rounded at the base ... 2. A. leptocoma. ^ 
Panicle less compound, stiff and contracted ; 
rays and peduncles finely filiform ,the latter 
9-12 lin. long ; awn 7 lin. long, column dark 
brown ; blades of upper leaves not quite 
1 lin. wide, passing gradually into the base 3. A. lenui folia. Y
