Bhutan id KW 3: 1 image. Segregating posts due to same subject: Can you all help me to conform this species Heterosmilax japonica It does not match with Heterosmilax japonica as per FoC illustration, Flickr, Flickriver, GBIF, Research gate Difficult to ID with this image only ! I think it is Aristolochia. May be A. tagala Or griffithii
