 Afr. V. 563. Glabrous. Stolons 2-6 in. long, hardly J^ in. in diam., 

 clothed by bright yellow-brown thin scales, producing near their ends 

 ovoid bulbs exceeding J in, in diam., with a thick black longitudinally- 

 striate coat. Stem springing from the bulb, carrying up the lowest 

 node near the surface of the ground and there rooting (as in the 

 Cape C. usiiatus, Burchell), 1-2 ft. long, rather stout, acutely triquetrous 

 at the top. Leaves as long as the stem, up to J-J in. broad, tough, 

 thick, shining. Umbel simple or subcompound, 4-5 in. in diam., open ; 

 bracts 4-5, similar to the leaves, lowest overtopping the umbel. Spikes 

 of 8-30 gpikelets rather loosely arranged. Spikelets spreading at right 

 angles, shining-red, ^ by ^^ in., compressed, 7-10-flowered ; wings of 

 the rhachilla persistent, holding back for a time the ripe nut. Glumes 

 rather remote, rounded on the back, strongly striate, muticous, sub- 

 acute. Nut ^ the length of the glume, oblong-obovoid ; style shorter 

 than the nut, with 3 long branches. — C. B. Clarke in Bull. Herb. Boiss.

This species is like, and exceedingly near in structure, to C. esculenh'.s, of which 

 the bulbs differ (being zonate). But the shining foliiige and very glistening red 

 s])ikelets suffice to distinguish it.
