Pl. go through Ampelocissus‎‎ (Vitaceae) page with comparative images of species in efloraofindia. On clicking the link of species, one can check the complete details. Genus pages generally give details of most of the species found in India.
I request you to pl. go through & point out mistakes, if any. I hope this will aid in identifications in future. If anybody can send images of other species of this genus (for incorporation in the website), if any, or can identify unidentified images, it will be really nice.
