The species in Apocissus were formerly placed in Cissus, a large genus with a wide distribution in the tropics and subtropics. They are distinguished from Cissus by the presence of domatia and/or ‘pouch-like' stipules. Jackes and Trias-Blasi (2023) concluded that Apocissus diverged from the core Cissus clade in the early Eocene, when South America and Australia were still connected via Antarctica.^[1]
