Stellenbosch University Botanical Garden, South Africa

Common name: Aroena, Quaqua

Family: Apocynaceae (Dogbane)

Distribution: Southwestern Africa

IUCN Red list: Not evaluated

National red list: Least Concern

Life form: Succulent plant

Comments: The aroena has been used by the Khoi-khoin for many generations, and will make a valuable addition to a veld-food garden. The knoblike thorns are removed and the stems are eaten raw, or can be sliced and added to a salad. Two 10 cm lengths are enough to suppress thirst and hunger for a day.
