This climber was photographed in Nov. 2008 at Mizoram. These are the only photographs available with me. 
This climber reminded me of Dioscorea pentaphylla which we see in Sahyadri ranges...
Date / Time: 12th Nov. / 09:30AM
Location: Mizoram

Habitat: Wild
plant habit: Climber

Hopefully this can be Dioscorea pentaphylla is the leaves are palmately compound with 5 leaflets !!
No! This is not D. pentaphylla!
Looks like D. oppositifolia.
D. oppositifolia is a good choice but can confirm as the leaf orientation is not visible.
Thanks ...
One of my friend has suggested Dioscorea glabra. Requesting you to have a look at following links (Description & illustration).
