Nymphaea alba L. ??

I think images insufficient as Nymphaea candida C. Presl and Nymphaea alba are closely related as per keys.

4 (3) Stigma almost flat with small hemispheric projection. Filaments of innermost stamens usually as broad as anthers   3 Nymphaea alba
+ Stigma strongly concave with conical central projection. Filaments of innermost stamens lanceolate   4 Nymphaea candida

Keys from Flora of China:
4 (3) Rhizomes repent; insertion of calyx on receptacle circular; filaments of inner stamens ± as wide as anthers   1 N. alba
+ Rhizomes erect or ascending; insertion of calyx on receptacle ± tetragonous; filaments of inner stamens wider than anthers   2 N. candida

Ok …!
