Bergeranthus addoensis L.Bolus
Addo bergeranthus
Bergeranthus addoensis is a species endemic to the area surrounding Addo Elephant National Park in the South African Eastern Cape. Described by South African botanist Louisa Bolus, it forms moderately caespitose clumps with semi-cylindrical to triangular leaves and produces typical diurnal yellow flowers. Less common in cultivation than B. multiceps but appreciated by collectors for its origin in an area of high conservation value.

"The distribution of B. addoensis within and around Addo Elephant National Park links it to one of the most biodiverse and protected ecosystems in the Eastern Cape. Population studies could provide valuable data on the biogeography of the genus in the Uitenhage-Addo corridor."
