Oh my god ! What a clue …!
I guess it is Aspidopterys nutans (Roxb. ex DC.) A.Juss. which is listed in the Book of Karnali Province.

Yes, it appears so.
Flora of China keys says “Leaf blade abaxially sericeous pubescent.” for A.nutans.

b. Leaves and inflorescences rusty or flavid-villous; samaras rounded at apex 10. Aspidopterys nutans
