Mozamb. Dist. German East Africa: Kilimanjaro; 3500 ft., Volkens, 1620! 
This has been issued from Berlin as C. fenzelianus, Steud., to which it is not 
(owing to the very remote glumes) closely allied. It may prove a new species. 
90. C. nubicus, C. B. Clarke. Glabrous. Stolons ;', in. in diam., 
hardening into rhizomes. Stems up to 2 ft. long, triquetrous at the 
top, at the base erect, not at all bulbous. Leaves 12 by $4 in. 
Umbel 5-8 in. in diam., compound, dense with numerous spikelets, 
a bright ferruginous-red ; bracts 3—4, the lowest overtopping the umbei, 
similar to the leaves. Spikelets loosely spicate, up to 1 by } in., com- 
pressed, 20—30-flowered ; wings of the rhachilla ovate, hyaline, con- 
spicuous, finally deciduous. Glumes ovate-lanceolate, slenderly striate, 
acute, hardly mucronate, distant, in fruit spreading and hardly imbri- 
cate. Style short; branches 3, long, exserted. Nut 2 the length of 
the glume, oblong-ellipsoid, black.

This species is perhaps more nearly allied to some of the very large brigh 
coloured forms of C. rotundus, 
91. C. Zollingeri, Steud. in Zoll. Verz. Ind. Archip. ti. 62. 
Glabrous. Stems 1-3 ft. long, slender for their length, trigonous, 
smooth at the top, suberect at the base; stolons slender, clothed by 
striate brown scales, hardening into slender woody rhizomes. Leaves 
3—% the length of the stem, narrow, sometimes attaining } in. in breadth. 
Umbel irregular, straggling, usually nearly simple, but sometimes com- 
pound with the secondary rays up to 4-6 in. long, and the primary 
rays up to 6-12 in. long, sometimes with more numerous long Trays; 
sometimes with 1-2 rays, or reduced to a head; bracts about as long 
as the rays, or in the case of a contracted umbel much longer, similar 
to the leaves ; in the case of numerous rays the bracts are also numerous. 
Spikes very loosely spicate, of 3-9 spikelets. Spikelets 1 by $ oe 
20-flowered, yellow-green, compressed, subquadrangular; wings : 
rhachilla oblong, hyaline, finally deciduous. Glumes distant on ns 
rhachilla, ovate-oblong, obtuse, acute or mucronate; margins pi ’ 
nerveless, yellow; keel broad, green, closely 5—7-nerved. Nut 3 
length of the glume, obovoid, black, hardly curved. Style ee
