Found in Vandalur forest. Chennai.
There are no leaves found.
Only stem used for getting photosynthesis.
I have seen something like this in some gardens, nursery.

Sarcostemma sp.... only a guess

Pl. check comparative images at efi site. 
Most probably Cynanchum viminale after comparing with eFI site. Thanks ... Similar plant that looks alike: Euphorbia tirucalli seen in gardens.
