Long leaf in Dioscorea bulbifera


Could be but not sure! Images not so good.


I may be an optical illusion being side views. would be nice to have some enface views


It was also on a edge of the road beyond reach !


oh


I also more inclined towards it after going through comparative images and other closely related species. Leaf venation and aerial bulbils appear close.
Flora of China states that leaves alternate, simple; petiole 2.5–5.5 cm; leaf blade broadly cordate, 8–15(–26) × 2–14(–26) cm, glabrous, margin entire or slightly undulate, apex caudate-acuminate.
Flora of Pakistan states that leaves alternate, 4-5 cm long, 2.5-13.5 cm broad, ovate, more or less deeply cordate at the base, long acuminate, 9-nerved, petiole 2.5-12 cm long.
GBIF gives 8017 occurrences (showing how common it is). 

Also check the following species as per keys in Flora of Pakistan:
2 (1) Stem twining anticlockwise. Leaves opposite   Dioscorea belophylla
+ Stem twining clockwise. Leaves alternate   (3)
       
3 (2) Leaves glabrous on both sides. Female spikes in clusters, many flowered. Capsule longer than broad. Seeds winged at the base   Dioscorea bulbifera
+ Leaves glabrous above, pubescent along the veins and the veinules beneath. Female spikes solitary few-flowered. Capsule broader than long. Seeds Winged all round   Dioscorea deltoidea

Leaves appears to be opposite ? is it so ? If so, pl. check Dioscorea belophylla

Yes, opposite leaves. … is exactly on the mark. 


I guess … is right and listed in Nepal !
