Dear Sir, Thanks for writing me back!
Polygonum filicaule Wall. ex Meisn. is now known as Koenigia nepalensis D. Don. K. nepalensis is a very delicate and different plant. I have collected this from Himachal Pradesh which I'll upload tomorrow. Unfortunately, I am not able to open the Flowersofindia site here in Korea for the last few days. Therefore, not able to see the picture uploaded there. Anyway, in my view, the plant uploaded by you and Balkar sir is definitely Polygonum recumbens Royle ex Bab. Regards, Ritesh.
