Nice pictures Dinesh jee..!!!

.. By the way, I hope the term- ARACHNOSPERMA reffers to the Stamens, resembling a spider.....I hope so....

Is it the case here.??

........A curios mind's question.. ha..

... correct you are Parjanya ji, ... couple of days back, even Prashant (Awale) also doubted this to be Ipomoea arachnosperma.
Thus, it must be Ipomoea nil ... many thanks to both of you !!!

Regards.

Hello,

I agree Ipomoea nil based on all features especially the sepals

regards,

Ron

P.S. - Some of the wild strains of Ipomoea nil and Ipomoea hederacea
can be extremely difficult to differentiate despite anything posted in
any keys or papers anywhere..
