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.

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

a little overtopping the umbel. Spikelets 5-12 together, }—} by jy in,

The collection consists of 5 fine umbels. The species does not resemble any one 
in this group, and is perhaps really allied to C, amabilis, Vahl, though of very large 
size.
