This looks like a hybrid between C. grandis and (7. Kotoltan. The 

 stigma of the present species, as seen in the accompanying figure, somewhat 

 resembles that of C. grand is ; the calyx is more or less hirsute, as is the case with

 resemble also those of C. grandis. Flowers in the beginning of March.
