wards, resembling (before flowering) a laterally compressed ovate to 
ovate-lanceolate simple or compound spike 3-4 in. long with a suc- 
cession of up to 10 spathes enclosing tiers of up to 3 rays ; rays some- 
what unequal, finely filiform, up to 4 lin. long ; spathes narrowly 
lanceolate, rather firm, herbaceous with broader membranous to 
hyaline margins upwards, subglaucous, with a short herbaceous 
subulate to setaceous blade or bladeless, 2-2f in. long. Spatheoles 
narrowly lanceolate, acute, thinly herbaceous, up to 9 lin. long, pale 
green; peduncle 2 lin. long, filiform, tips truncate. Racemes 2- 
nate, divaricate, at length epinastically deflexed, 5-7 lin. long, 
white- villous, one subsessile, the other with a bare base, under 1 lin. 
long ; bases pubescent to villous, with truncate cilia te or ciliolate 
tips, that of the subsessile raceme stout, J lin. long, the adjacent 
pedicel short, barrel-shaped and hard; fertile joints linear, not 
quite 1J lin. long, densely hairy on the back and the angles, 
hairs increasing upwards to over 1J lin., tips obscurely cupular ; 
adjacent pedicels similar to the joints. Homogamous pair of 
spikelets 1 at the base of each raceme or only of the subsessile, 
sometimes the second also homogamous, but the sessile spikelet in- 
termediate as to shape and awn . Fertile spikelets linear to lanceolate- 
linear, acuminate, including the callus 3-3 J lin. long, glabrous, pale 
green, darker or brownish upwards ; callus short, obtuse, shortly 
bearded. Glumes equal, chartaceous ; lower shallowly concave on 
the back below the middle, keels acute, almost winged, minutely 
scaberulous, intracarinal nerves 4 in the acumen, the inner 2 short, 
the outer decurrent close to the keels ; upper glume narrowly 
lanceolate in profile, very acute, 1 -nerved, keel narrowly winged 
upwards. Lower floret reduced to a linear-oblong nerveless hyaline 
ciliolate valve, slightly shorter than the glumes. Upper floret ^ : 
valve very narrow, shortly 2-fid, sublinear and hyaline below the 
insertion of the awn, 1J in. long, lobes ovate-lanceolate, acute, ciliate ; 
awn a straight bristle up to 3 lin. long, not or shortly exserted from 
the spikelet. Anther 1J lin. long. Pedicelled spikelet linear- 
lanceolate, subacute, 3-3J lin. long, glabrous, brownish or reddish ; 
glumes unequal, lower chartaceous with very many close intra- 
carinal nerves, upper shorter, membranous, 3-nerved; valve equal 
to the upper glume, linear-oblong, obtuse, 2-nerved, ciliolate ; anthers 
1-| lin. long. — Andropogon sennarensis, Hochst. in Flora, 1844, 243.
