You have clearly mentioned in your initial post that the name *Ipomoea hederifolia* var. *lutea *does not appear in ars-grin and the plant list databases but appears in some other sites.
I am not a taxonomist Dinesh ji and thus would like to reserve my comments on your specific question [ie. What are your thoughts about *Ipomoea hederifolia* var. *lutea* ?] With regard to your other query [Is it possible to know from the leaf seen in this view (of the posted plant) ?] I feel the plant is *Ipomoea hederifolia* L.
