This climber does not have tendrils, hooks or spines to help it secure itself to or climb up a structure. But as the climber grows, the new shoots produce these 3 claw-up appendages for the same purpose. Some imaginative fellow then gave this climber its common name and there was no turning back.
Anyway, the first photo of the nest of red ants on the leaves of this climber freaked me out. Did I say I am allergic to some insect bites?
