lower glume slightly 2-toothed, long-ciliate from the hairs of the 
tightly inflexed margin, keels very narrowly or obscurely winged, 
wing rigidly ciliate, intracarinal nerves 5, the inner 3 very promi- 
nent and rough ; upper glume lanceolate, long and finely acuminate, 
hyaline, ciliate, 3-nerved ; lower floret as in the sessile spikelet ;

2. S. ischsemoides, ForsJc. FI. Mgypt.-Arab . 178. Annual ; culms 
usually in small fascicles, rarely over 1J ft. high, slender, terete, 
simple, 2- or 3-noded, middle and upper internodes slightly exserted, 
smooth, glabrous. Leaves glaucous, sheath terete, tight, or the 
upper somewhat inflated, smooth or slightly rough, glabrous ; 
ligules a fringe of stiff hairs ; blades linear, tapering to a long fine 
point, up to 5 in. long, 1-2 lin. wide, rather firm but hardly rigid, more 
or less scabrid, midrib fine like the 1 or 2 primary lateral nerves. 
Racemes solitary, or sometimes an additional 1 or 2 from the upper 
nodes, 1-3 in. long, erect or slightly nodding ; joints and pedicels 
parallel, sublinear, slightly compressed, 2 lin. long, very densely 
ciliate from white hairs along the angles, otherwise glabrous, tips 
more or less oblique. Sessile spikelets linear, 4J-7 lin. long, pale 
green, with a shortly bearded callus ; lower glume subchartaceous to 
chartaceous, with an unequally 2-toothed flat and membranous long 
beak, the teeth of which run out into mucros, deeply grooved, 
particularly below the middle, acutely 2-keeled, the outer keel 
generally winged upwards, intracarinal nerves 3-5, raised, rough, 
only distinct just above the groove ; upper glume and florets as in 
Sehima nervosum excepting the bristle of the glume which is over 
10 lin. long and the awn, the column of which is generally more 
brown than bronze in colour, and has much longer cilia along the 
spirals. Pedicelled spikelets narrowly lanceolate, long-acuminate
