… it would help if you could give key to Indian species of Fallopia, especially after F. pterocarpa having been reported by Hara from Himalayas.

This is Fallopia dumetorum as per images and references herein.
Looks different from Fallopia dentatoalata (F.Schmidt) Holub as per POWO and keys in Flora of Pakistan

I got confused by FoP illustration and no distribution of F. dentatoalata in India as per FoP, FoC and BSI Flora of India.

I think keys are better in Flora of China.
POWO gives distribution of F. dentatoalata in West Himalaya.
It is F. dentatoalata only.
