Cyphia volubilis is found from Namaqualand along the south coast of South Africa as well as inland along the Little Karoo eastwards to around Port Elizabeth. The species grows on sandstone and clayey slopes. Namaqualand is home to several baroe species such as C. sylvatica and C. undulata that are (or were) important in the diets of indigenous people.
The Cyphia genus forms part of the Campanulaceae or bellflower family. It was classified under Lobeliaceae at some stage in the past.
