SK 3749 20 June 2023: 7 high res. images.

Did not find a match. Leaf margin looks different.

Pl. check at

Is it some Vitaceae? Just a guess, looking at the flower and leaf margin!

I found climbers/ lianas only in Vitaceae. I could not find a match for a tree !

Could it be a Rubiacean member?

Maybe

Also there may be some possibility of Celastraceae:
