Hibridek, kultivárok és egyéb bizonytalan eredetű növények - Stapelia angulata Todaro, 1876

This taxon is rarely seen in the literature on Asclepiadaceae. It was described first by Agostino Todaro in 1876. Based on his description its natural habitat is found near to the Cape of Good Hope in South Africa. It flowers in early autumn in Europe. The flowers lay on the surface. Sepals are dark reddish-brownish in colour. In 1909, Brown wrote first about that the taxon may have a hybrid origin. Finally, Paul V. Heath placed it in a hybrid genus under the name × Tromostapelia mutabilis var. angulata.
