Osyris compressa (Cape sumach or pruimbos) is a facultatively hemiparasitic, mainly South African plant of the sandalwood family, Santalaceae. Until recently, the favoured binomial name was Colpoon compressum, but around 2001, the genus Colpoon was included in Osyris on the basis of comparative DNA studies.That assignment is not final, however, and according to the Kew Gardens plant list, Colpoon compressum P.J.Bergius, though still in review, is the accepted name.
