Tliis has been issued from Berlin as C. fenzelianus, Steud., to v.hicli it is not 

 (owing to the very remote glumes) closely allied. It may prove a new species. 



90. C. nubicus, C. i?. CZa?*A;e. 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 \-\ in. 

 Umbel r)-8 in. in diam., compound, dense with numerous spikelets, 

 a bright ferruginous-red ; bracts 3-4, the lowest overtopping the umbel, 

 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 'i the length of 

 the glume, oblong-ellipsoid, black.

This species is perhaps more nearly allied to some of the very large bright- 

 coloured forms of C. rotundus. 



91. C. Zollingeri, Steud. in Zoll. Verz. Ind. Archip. ii. 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 

 |^-| the length of the stem, narrow, sometimes attaining J 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 G-12 in. long, sometimes with more numerous long rays, 

 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 J^ in., 

 20-flowered, yellow-green, compressed, subquadrangular ; wings of 

 rhachilla oblong, hyaline, finally deciduous. Glumes distant on the 

 rhachilla, ovate-oblong, obtuse, acute or mucronate; margins broad, 

 nerveless, yellow; keel broad, green, closely 5-7-nerved. Xut ^ the 

 length of the glume, obovoid, black, hardly curved. Style short ; 

 branches 3, long, shortly exserted. — Steud. Syn. PI. Glum. ii. 17;
