21. S. Steudneri, Boeck. in Linnea, xxxvi. 733. Stems much 
thickened at the base, woody, covered by torn leaf-sheaths. Spikelets 
distinct, sessile, in a head more than } in. broad, squarrose from the 
subrecurved points of the glumes; otherwise as S. kyllingioides.—

22. S. Lugardi, C. B. Clarke. Annual, glabrous. Stems tufted, 
2 in. long, rather stout. Leaves as long as the stem, ;'; in. broad. In- 
florescence a dense compound head } in. in diam., or more rarely an 
umbel. The 1 or 2 rays up to }-} in. long; bracts 2 in. long, spreading, 
similar to the leaves. Spikes } to } in. long, very dense, compound, purple 
and green, 1-4 in the head. Spikelets less than } in. long, 5-8-flowered. 
Glumes elliptic, 5-7-nerved, the green keel excurrent into a recurved 
mucro less than } the length of the glume. Seta 0. Stamens 1 (or 2) 
with a very small square anther. Nut narrow-oblong, trigonous, 
smooth, brown. Style linear 2 the length of the nut, branches 3. 
Mozamb. Dist. British Central Africa : Ngami-land; Okavango Valley, 3000 
ft., growing in sand, Lugard, 290! 
This greatly resembles Scirpus Hystrix, Thunb. ; but the point of the glume is 
much shorter and the nut altogether anlike. 
23. S. squarrosus, Linn. Mant. 181. A small glabrous tufted 
annual. Stems 2-8 in. (rarely 16 in.) long. Leaves 4 the length of 
the stem, 3,—}in. broad. Head of 1-6 (rarely 10) squarrose spike- 
lets ; bracts 3-5, leaf-like, spreading or pendent, 1-2 (sometimes 4) in. 
long. Spikelets 4-4 in. long, with very many flowers, greenish or 
brownish. Glumes narrowly obovate, suddenly narrowed into a linear 
subobtuse mucro not longer than the glume, very caducous in fruit 
beginning from the lowest nut-bearing glume. Hypogynous pristles 0. 
Stamen 1 or rarely 2; anther very small, oblong. Style scarcely any; 
branches 3, short, much recurved. Nut 3 the length of the glume 
(exclusive of the mucro), obovoid-ellipsoid, trigonous, yellow-brown OF 
ultimately black, smooth, the outermost cells minute quadrangular, 5° 
that the nut only appears reticulated under a strong magnification.—
