Cardamine flexuosa With. ??

I think it looks different from images at Cardamine flexuosa With. as well as existing species as per comparative images at Cardamine

Could not match unless this is a different sp.

Any resemblance to the enclosed  efi image ?

It is possible that images in the screenshot post may not be correctly identified.

Pl. check other species in GBIF.

Pl. check other species in GBIF as per Checklist of Nepal.

I have already done that ! The screenshot was from the efi!

I checked relevant species in GBIF as per Checklist of Nepal
I think it is close to Cardamine yunnanensis Franch. as per GBIF specimens:

Thank you …! I think you are right !
