'Cardaba' is in the Saba subgroup, genetically it is 1 part M. acuminata (the species which provides the red marks on the leaves) and 2 parts M. balbisiana. I have never seen any ABB plants have that much red on the leaves, and also the common ones available (Ice Cream, Saba, Namwah) tend to have rather waxy petioles which are very round and have closed canals. The plant on the left has little wax compared to the one on the right and open, winged petiole canals. Addtionally, not only does it not look like 'Cardaba', but it looks consistent with a Cavendish, which are very common plants.
