C. denudaUis, Linn, f., is common throughout South Africa, and hardly differs 

 from C. sphcerospermus except in the want of leaves. The two have been much 

 mixed, and finally united by Uoeckoler. It is remarkable that the type example of 

 Ridley's var. aphyllus, in herb. Welwitsch,, has long leaves.

Also in South Africa. 



This variety differs from the type in unimportant points only. In recording 

 it, 1 am able to explain that it was sent me marked Cifperus tviqueter, as 1 

 supposed, by Boeckeler; and I have given it the varietal name triqueter thereon. 

 But I find tliat it was erroneously named triqueter, not by Boeckeler j and that 

 Boeckeler's triqueter was C. amahilis above.
