7. M. macropus, C. B. Clarke in Durand & Schinz, Conspect. Fl. 
Afr. v. 590. Glabrous. Stems 10-20 in. long, slender, at the top 
trigonous and smooth, at the base ovoid-oblong, very much thickened 
by the sheaths of which the remains persist as coarse fibres; stems 
approximated in dense tufts. Leaves }—? the length of the stem, very 
narrow, long setaceous at the tips. Head 1, ovoid, 4 in. in diam., dirty 
white ; bracts 3, similar to the leaves, lowest 1-2 in. long, somewhat 
dilated at the base. Spikelets 1 in. long, narrow-lanceolate, very little 
compressed, dirty straw-coloured, 8-10-flowered, producing 6-8 nuts; 
caducous in one piece above the two lowest empty glumes. Glumes 
ovate, obtuse, obscurely 7—1ll-ribbed. Nut 4-3? the length of the 
glume, ellipsoid, trigonous, pyramidal at each end, dark-brown. Style 
nearly as long as the nut; branches 3, linear.—Cyperus macropus, 
Boeck. in Flora, 1879, 550.

8. M. somaliensis, C. B. Clarke in Kew Bulletin, 1895, 229. 
Glabrous. Stems 4-8 in. long, slender, at the top trigonous and 
smooth, at the base oblong-ellipsoid, thickened by scarious (hardly 
fimbriate) leaf-sheaths. Leaves 4—2 the length of the stem, setaceous, 
very weak. Head 1, 3-1 in. in diam., of 5-11 digitate (or almost 
Spicate) chestnut-red spikelets ; bracts 3, setaceous, weak, lowest 1-2 in 
long. Spikelets } by 1,1, in., 12-16-flowered, hardly at all com- 
pressed, caducous in one piece above the two lowest empty glumes. 
Glumes closely packed, elliptic-acuminate acute, very strongly 13- 
ribbed, not keeled, persistent. Nut hardly } the length of the glume, 
trigonous, obovoid, dark brown. Style very slender, nearly black, 
much longer than the nut ; branches 3, linear, rather short.

9. M. Schimperi, Hochst. in Flora, 1841, i. Intell. 20. Glabrous. 
Stolons 0. Stems approximate, 3-14 in. long, slender, at the top 
trigonous and smooth, at the base oblong-thickened by brown scarious 
entire or ultimately fimbriate leaf-sheaths. Leaves often as long as 
the stem, ,1,-1 in. broad, weak. Head of usually 3-4 distinct spikes, 
the central subcylindric, the lateral often shorter ; bracts 3—5, similar to 
the leaves, lowest up to 6 in. long. Spikelets numerous, green more or 
less variegated with red, } in. long, oblong, compressed, producing 2-4 
nuts, deciduous in one piece above the two lowest barren glumes. 
Glumes ovate, subacute, 12—20-ribbed. Nut trigonous, oblong or 
oblong-ellipsoid, 2-4 the length of the glumes, dark brown, dotted. 
Style rather shorter than the nut; branches 3, longish.—Steud.
