Dioscorea !

What are the species of Dioscorea reported from your area?

Sorry !! Not available in my books.

In the Flora of the Lushai Hills, the following spp. are listed/recorded :- Dioscorea alata, D bulbifera, D. glabra, D. pentaphylla, D.sativa and D.trinervia

I think it may be D.glabra as per GBIF specimen.
Flora of China says:
Leaves alternate basally on stem, opposite distally on stem, simple; leaf blade drying blackish, usually ovate or long elliptic-ovate to lanceolate, 5–17(–24) × 0.5–10(–13) cm, glabrous, basal veins 5–9, base cordate to truncate or rounded, rarely sagittate or hastate, apex acuminate or caudate. 

Dioscorea oppositifolia

Going by distribution in BSI Flora of India, D.glabra is more likely.
BSI Flora of India does not give any distribution in your area for Dioscorea oppositifolia L.

Ok, thanks sir

Dioscorea wattii ?

Who suggested the id?
It seems possible as per GBIF specimens- one.
But difficult to say without inflorescence.

Suggested by Rohan Maity, BSI, Itanagar, A.P.

Yes, we should follow his advice.
