margin and the keel ; spathes narrow, inflated above, 1-1 £ in. long, 
reddish, glabrous, often with a rudimentary blade. Eacemes on 
peduncles which are at length slightly exserted and thickened at 
the tips, with a large calceoliform appendage, 1-1J in. long, 6-8- 
jointed, purplish ; joints stout, clavate, gradually widening upwards, 
about 3 lin. long, including the asymmetrical urceolate denticulate 
appendage, glabrous except for a basal tuft of snow-white hairs, 
reddish above, paler below ; pedicels similar but more linear and 
with a much smaller appendage. Sessile spikelet linear-subulate, 
including the glabrous callus, 3j-4 lin. long, pale below, slightly 
reddish above. Glumes equal ; lower slightly convex on the back, 
with a 2-setulose acumen, subcoriaceous, minutely granular on the 
back, with 5 very fine intracarinal nerves ; upper glume acuminate, 
passing into a bristle 1-1 J lin. long, delicately 3-nerved. Lower floret 
reduced to a hyaline nerveless valve. Upper floret 2-fid to three- 
quarters of its length ; awn 7-8 lin. long, with a dark column. Pedi- 
celled spikelet barren, subulate, lanceolate, reddish, 1J-2 lin. long ; 
lower glume 5-nerved, with a short bristle from between 2 minute 
teeth ; upper 1-nerved, also with a short bristle. Florets reduced 
to a minute hyaline valve. — Andropogon urceolatus, Hack, in Flora,

Schweinfurth, 1031, is represented in the herbarium of the British Museum 
by a large complete specimen of S. exile , accompanied by a capsule, containing 
the fragments of what is evidently a raceme of Hackel’s Androjpogon urceolatus . 
This is all I have seen of his species.

5. S. exil e^Stapf. Annual. Culms fascicled, from few to very 
many, erect, many-noded, from | to over 2 ft. high, terete or slightly 
compressed below, branched from the base or at least from the 
upper nodes, branches 2 to many from a node, dividing again, very 
slender to filiform, glabrous. Leaf-sheaths somewhat loose, terete, 
or the lower ones compressed and keeled, the lower easily slipping 
off the internodes, glabrous, smooth, the uppermost spathaceous ; 
ligules membranous, short, rounded ; blades linear, tapering to an 
acute point, very variable in length, from less than 1 in. to 6 in. long, 
1-1J lin. wide (when flattened), glabrous or with some very long 
fine hairs towards the junction with the sheath, scabrid along the 
margin and towards the tip, green, soon turning red, midrib promi- 
nent below, whitish, lateral nerves numerous, very fine ; spathes 
narrow, acute, 1 to over 1J in. long, as long as or slightly shorter 
than the racemes, narrowly linear-lanceolate, acute, at length often 
turning brilliantly red. Eacemes subsessile in the spathe, or on 
distinct, but very short, peduncles with hollowed out clavate tips 
which on one side are produced into a short obtuse appendage, f-li 
in. long, 8-12-jointed ; joints 2-3 lin. long, gradually widening
