This species differs from C. DecJcenii by the smaller spikeleti. liuclianan f.lT, 

 and Wnyte's example are identical with the typical C. Bnroni from .Madagkscir' 

 As to Hoist, 3385, it is nearer C. Deckenii than C. Mannii, hut the bracts attain - in. 

 in width, so that it does not exactly match anything e'se ; the spikeleU are too l.m- 

 with too distant glumes to match C. Ajax.

Tliis was marked by Boeckeler C. lonrjifolius, Poiret, which has much larger 

 spikelets and nuts and is near C. diffusus, Vahl. It is near the largo examples of 

 C Baroni, but the slender branchlets of tlie umbel and delicate spikelets give it a 

 different asjiect. Whyte's Mlanji plant, which I formerly referred here, I have 

 above renamed C. Deckenii.
