This species is very unlike any other, nor can I guess its true affinity. I 

 formerly arranged it with the Section Tunicatce ; but, if it should prove to have 

 evanescent stolons producing bulbils, the spikelets will be difFei-ent from those in 

 any of the Tunicatce. 



109. C. radiatus, Vahl, Enum. ii. 369. Glabrous. Rhizome ; 

 lateral shoots are sometimes formed at the base of the stem, flowering the 

 second year. Stem, when fairly developed, 1-2 ft. long, but small 

 examples 6 8 in. are frequent, examples only 1 in. long have occurred. 

 Leaves f the length of the stem, up to r in. broad. Umbel in well- 

 developed examples 6-10 in. in diam., but in African examples often 

 contracted, sometimes into one dense head ; bracts similar to the leaves, 

 much overtopping the inflorescence. Spikes digitate, their pedicels 

 hardly exceeding ^ in. in length, dense, cylindric, with suberect or 

 spreading spikelets, 1 by ^-| in. Spikelets \-f by -}jj in., 10-36- 

 flowered, strongly compressed, pallid or finally brownish, not or rarely 

 highly coloured red or yellow; wings of the rhachilla oblong, per-

 on the rhachilla and (even in fruit) tightly imbricate. Stamens 3; 

 anthers small, muticous. Nut |-J the length of the glume, ovoid or
