Glabrous (even the rhachis of spikes). Stem l-4 ft. Leaves often as long as 

 stein, | | in. broad. Umbel 8-24 in. in diam. ; bracts usually longer than umbel. 

 Secondary umbels usually conspicuously bracteoled; spikes corymbose, shortly 

 peduncled. Spikelets often 55 by -^j- T V m -> verv variable in size, yellow golden 

 rufous or brown. Qlumes boat-shaped, ovate, scarcely mucronate. The African 

 C. auricomus, Sieber, with which this was united by Bentham, is very closely allied, 

 but differs by the stem sub-3-winged at top, the irregular umbel and other small 

 points.
