Strophanthus speciosus is also known as Poison Rope.
Native to southern Africa.

As the common name poison rope suggests it contains toxic compounds.
These are in the form of cardiac glycosides, similar to those found in Digitalis.

Native hunters used preparations made from the seeds as a virulent arrow poison.
