In the wild (the dry spiny forests of western and southwestern Madagascar), one often sees these plants growing on top of shrubs and small trees.
The climbing or creeping branches are up to 5 m long; they bear few tendrils, which are branched at their tips and grey-green leaves, which are 3.5-5.5 cm long and 2.5-5 cm wide.
The inconspicuous flowers are greenish-yellow.
