It is related to C. pachycentron, Franch., and C. trifoliolaia, 
Franch., but from these and all the allied species easily recognised 
by its broad shallowly cut basal leaves. I am doubtful whether 
the locality for No. 67 is right. The specimen is quite identical 
with No. 68 ; it may be a mistake with the label.
