Dioscorea orangeana

Dioscorea orangeana, is a tuberous vining flowering plant in the genus "Dioscorea", endemic the Forêt d’Orangea near Antsiranana in Madagascar, from which it derives its name. The tuber is possibly edible, and unlike most other "Dioscorea" species, the tuber has many finger-like lobes as opposed to a single tuber. Because the plant is new to science and the possible harvesting by local populations, the conservation status of "Dioscorea orangeana" is of great concern.
