Many species of Adenia have unusual forms, with male and female flowers on different shoots or different plants, or they have their tendrils transformed into thorns. Perhaps the most peculiar are the species with large tuberous stems that can store water and nutrients. During the humid season, they send out vegetative and flowering shoots. Adenia aculeata grows in the deserts of eastern Ethiopia, Somalia, and northeastern Kenya.
