Dear all please help me in the identification of this wild dioscorea; leaves thin coriaceous, basal nerves 7, petiole 2-4 cm long, igmented at pulvinii, 4-8 cm wide and long, almost orbicular, base rounded, no bulbils found, entire plant almost glabrous; roots tuberous deep in the rocks.
Dioscorea species in efi with details & keys etc.
Since leaves are 7-nerved the closest match I could find is Dioscorea glabra Roxb. Please check probability –
