alndropogon| XXVIII, GRAMINES. 149 
spikelets narrowly lanceolate-oval, glabrous except for a tuft of 
short white hairs at the base of the acute callus, callus medianly 
furrowed, outer glume linear-oblong with a strong median furrow 
for 2 of its length from the base, coriaceous becoming scarious at the 
Apex, Margin incurved membranaceous, slightly exceeding gl. IT. 
which is narrowly navicular, subacute witb keel hispidulous on 
the upper half; gl. III. shorter, hyaline, linear-oblong, blunt; 
fertile glume linear-oblong, deeply bipartite, with a strong kneed 
awn springing from the notch, column deep-brown shortly hairy, 
subula pale, scabridulous ; stalked spikelet exceeding the sessile, 
dorsally flattened, lanceolate, outer glume with hispidulous 
carinate margins, midrib conspicuous with 5 less conspicuous 
nerves on each side, apex triaristulate ; gl. II. shorter, narrowly 
oval, 5-nerved with incurved hyaline ciliate margins; gl. III. and 
LV. shorter, equal. 
About 3 ft. high, culms not exceeding 1 line in diameter ; 
leaf-sheaths 1 to 12 in. long, ligule reduced to a scarious 
ridge less than + line long; lowermost (linear) leaves to 6 in. 
long by 14 line wide, upper (with cordate base) 2 to 4 in. long, 
3 to 6 lines broad at the base. Racemes 1} in. and 1 in. respect- 
ively, not including awns, approximate, rhachis-joint 33 lines, 
including the glabrous cup (14 line); sessile spikelet 4 to 43 
lines, including the callus (1 line); gl. I. 4-nerved, greenish 
becoming reddish at the apex; gl. IT. 31 lines long, subcoriaceous, 
glabrous ; gl. TII. 23 lines, faintly 2-nerved with margins in- 
curved ; fertile glume 23 lines, awn 2 in. column slightly exceeding 
subula, Pedicelled spikelet 8 lines, outer glume 5 to 6 lines long, 
median aristula 1 to 2 lines, Jateral ones very short; gl. IT. 
41 lines long; gls. IIJ. and IV. 31 lines, the former 3-nerved 
lanceolate, subhyaline, the latter hyaline, narrow, 1-nerved. 
Near the South African A. amplectens Nees, but differs in the 
marked broadly cordate-based leaves, especially on the stronger 
(flowering) shoot, the shorter few-flowered racemes, and the 
longer and stronger awns of the sessile spikelets.
