Also in the Comoro Islands. 



This species is well separated from the preceding by its huge size and very small 

 few-flowered spikelets. As to the synonymy cited, I have seen authenticated 

 examples of the seven names. 



()2. C. aureobmneus, C. B. Clarke. Glabrous. Top of the 

 stem J in. in diam., triquetrous. Umbel 8 in. in diam., decompound, 

 dense with numerous golden-brown spikes; bracts 3-5, suberect, 

 lowest \ in. broad, usually much shorter than the umbel, but in one case 

 a little overtopping the umbel. Spikelets 5-12 together, J— J by -^ in., 

 compressed, lJ:-oO -flowered, with parallel sides. Glumes elliptic, some- 

 what o-nerved, rounded at the top, with narrow scarious torn margin.

The collection consists of 5 fine umbels. The species does not resemble any one 

 in this L^roup, and is perhaps really allied to C. amahitis, Vahl, though of very large
