Yes sir you are very correctly pointed out, Merremia umbellata subsp. Umbellata is now Camonea umbellata. Native to Africa and introduced to various parts of world including India.
Previously the plant collected from various regions of India basically from WG and A & N was not the Camonea umbellata as it is having very fever flowers in inflorescence as compared to the specimen collected by me. After molecular analysis ( Paper By Dr. S.R.YADAV SIR) it is found that species reported in india was actually was Camonea pilosa and not camonea umbellata.
I have checked the available Harberium online too, which proves that my specimen is Camonea umbellata.
Regards and thanks sir.
