3. S. delicatum, Stapf. Annual. Culms up to over 1 ft. high, 
very slender, subcompressed below, terete above, 4-6-noded, spar- 
ingly branched from above the 2nd or 3rd node, with all the branches 
flowering and erect, rarely almost simple, glabrous and smooth. 
Leaf-sheaths tight, the lower somewhat compressed and keeled, the 
upper rounded, all glabrous and smooth ; ligules very short, truncate, 
glabrous ; blades very narrowly linear, tapering to a fine point, the 
lowest J-1J in. long by J lin. wide, the following up to 2J in. long 
and less than J lin. wide, all folded at first, then flat, glabrous or with 
scattered hairs, smooth except towards the tips, reddish, midrib 
wide and whitish above, slender and raised below ; flowering 
branches geminate or the uppermost solitary, simple, finely filiform ; 
spathe very slender and tight, 1-1J in. long, with or without rudi- 
mentary subulate blades, reddish, glabrous or hairy upwards ; 
peduncles at length exserted by 1-2 in., thickened at the cupular 
tips which are expanded into an oblique ovate s carious appendage, 
J-f lin. long. Racemes up to 8 lin. long, very slender, pale brownish, 
very fragile, 4-6-jointed ; joints cuneate-linear, up to 1 lin. long, 
glabrous, with a cupular unequally 2-toothed appendage ; pedicels 
very slender, linear, slightly longer than the joints, without an 
appendage, densely and subequally ciliate on the outer angle. Sessile 
spikelets narrowly linear-lanceolate, lj-lf lin. long, including the 
shortly bearded small callus, glabrous. Glumes unequal ; lower 
chartaceous, 2-mucronate, convex on the back, smooth below, 
scaberulous above the middle, keels very narrowly winged ; upper 
glume not much over 1 lin. long, membranous, obliquely lanceolate 
in profile, mucronulate, 1-nerved. Lower floret reduced to an 
oblong obtuse hyaline purplish valve, faintly 2-nerved and ciliolate, 
1 lin. long. Upper floret $ : valve oblong, 2-fid to beyond the 
middle, 3-nerved at the base ; segments linear-lanceolate, acute, 
ciliolate ; awn up to 8 lin. long, very slender, kneed at and twisted 
below the middle, very minutely scaberulous ; valvule 0. Anthers 
\ lin. long. Pedicelled spikelet barren, slightly over 1J lin. long. 
Glumes very unequal ; lower oblong, produced into a short bristle, 
keels broadly winged, wings whitish, intracarinal nerves very faint, 
about 4 ; upper glume lanceolate, acuminate, 1 lin. long, finely 
3-nerved or often much reduced or quite suppressed. Florets 0.

4. S. urceolatum. Stapf. Annual. Culms erect, up to 1 ft. high, 
slender, slightly branched above, branches flowering, solitary, 
appressed, simple, short. Leaf -sheaths compressed or loose, gla- 
brous, the uppermost spathiform ; ligules membranous, truncate, 
glabrous ; blades linear, acuminate, flat, the lowest small, the inter- 
mediate up to 2 in. long by 1J lin. wide, reddish, glabrous or with a 
few long tubercle-based hairs, scaberulous above, scabrid along the
