¿ Dioscorea sp. ?  
Dear friends,
I am assuming the inflorescence seen in posted pictures belong to Dioscorea, and this is a very bad guess. There is a mix of many leaves - Dioscorea, Clematis / Naravelia and many others. The branched inflorescence also reminds me of moonseed family member - Diploclisia. I will be glad to know ID just to family level.
so which is the dioscorea leaf?
In the first picture, a stem runs from bottom centre to top centre. There are 4 half folded leaves on the stem. They are Dioscorea leaves.
Here attached is the photo with red circles over the 4 leaves that I mentioned in earlier message, plus another 2 leaves on the stem bearing the inflorescence.
Inflorescence of posted plant resembles that of Dioscorea oppositifolia ... those familiar with Dioscorea spp. may please comment.
