1)4. C. gracilinux, C. B. Clarke in Journ. Linn. 8oc. xxi. 3 62. 

 Glabrous. Stems 2 ft. high, at the top trigonous and smooth ; 

 stolons numerous, slender, clothed by striate brown scales. Leaves 

 J the length of the stem, i in. broad. Umbel 6-12 in. in diam., com- 

 pound, open ; bracts much longer than the umbel, similar to the leaves. 

 Spikes loosely spicate, of 5-11 spikelets. Spikelets f by J^ in., com- 

 pressed, hardly at all quadrangular, 10~16-flowered, dirty-white ; wings 

 of rhachilla elliptic-lanceolate, hyaline. Glumes approximate on the 

 rhachilla, ovate- oblong subobtuse, ultimately obliquely spreading but 

 imbricate, ^xat 4 the length of the glume, oblong or narrowly 

 ellipsoid; style 3-fid.— C. B. Clarke in Durand' &. Schinz, Conspect.

 Afr. V. 500. Glabrous. Bhizome creeping. Stem 1 ft. high, rather 

 stout, at the top trigonous and smooth. Leaves | the length of 

 the stem, l-i in. broad, Umbel 6-8 in. in diam., very dense ; 

 bracts overtopping the umbel, similar to the leaves. Spikelets 40-60 

 together in dense spikes, dusky straw-coloured, 1^ by ^ in., up 

 to 00-flowered, slightly compressed ; wings of the rhachilla linear-, 

 lanceolate, falcate. Glumes approximate on the rhachilla, scarcely 

 ^ in. long, ovate, obtuse. Nut J the length of the glume, ovoid^ 

 chestnut-black ; style as long as the nut; branches 3, linear, exserted.

90. C. natalensis, Hochst. ex Krauss in Flora, 1845, 755. 

 Glabrous, Rhizome long-creeping, ^ in. in diam. Leaves in Krauss' 

 description, often 2-0 in. long, in Krauss' type 20 in. long, up to \ in. 

 broad. L^mbel-rays 3-0, up to 1-4 in. long, the secondary umbel at the end 

 of each, congested into a compound head of 12-35 spikelets; bracts 

 usually short, but overtopping the umbel when the leaves are long. 

 Spikelets f by ^^ in., very slightly compressed, dirty straw-coloured, 

 12-24- flowered, wings of rhachilla linear, i.e. hardly any. Glumes 

 ovate, hardly acute, 9-11-nerved, in fruit obliquely spreading but 

 imbricate, hard in texture. Nut hardly | the length of the glume, 

 oblong, obtuse, chestnut-black. Style nearly as long as the nut ; 

 branches 3, linear, exserted. — Boeck. in Linnaea, xxxvi. 343; C. B.
