This looks like a hybrid between C. grand-is and C. Kotokan. The 

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

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

 the latter. There is a slight constriction between ovary and style. The anthers 

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