Leaves of D. bulbifera L. may attain 10 inch x 10 inch (ref. Haines) and may look similar. But leaves here are larger than that. FBI has one species D. sativa L. having 14 inch leaf.
But D. sativa L. is now synonymous with D. villosa L. which feature much smaller leaf as per following sites -
I do not have any idea of what this species can be.
Please ignore my earlier reply, it was simply useless.
In attached images leaf is much broader than long or can say that broader as longer, leaf size varies with ecology of surroundings or habitat, there is no define key on leaf size for Dioscorea. In every Flora (publication) we have different leaf sizes.
Kindly check for Dioscorea wallichii Hook.f. which has similar kind of leaves (long=broad), also check the link below:
If the stem is winged then this is D. alata sans the leaf size.
