Afr. v. 563. Glabrous. Stolons 2-6 in. long, hardly ,3, in. in diam., 
clothed by bright yellow-brown thin scales, producing near their ends 
ovoid bulbs exceeding } 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. usitatus, Burchell), 1-2 ft. long, rather stout, acutely triquetrous 
at the top. Leaves as long as the stem, up to 4-4 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 spikelets 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 4 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. esculentus, of which 
the bulbs differ (being zonate). But the shining foliage and very glistening red 
Spikelets snffice to distinguish it.
