Found in South Africa, Angola, Namibia, Botswana, and Zimbabwe, Tavaresia is an interesting and unique Stapeliad like no other. The spines are reminiscent of Hoodia though much finer and flexible. The flower is more like Huernia though usually bigger than typical flowers of the Huernia genus. The genus is named for Josť Tavares de Macedo, a 19th century Portuguese botanist who collected in Africa.
Tavaresia barklyi is probably the only species commonly found in cultivation. And it has been hybridized with Orbea variegata successfully. It's long tube shaped flowers are very attractive along with the unusual spination of the plant.
This is my second shot at this plant. I lost the first one to rot last year. Both came from Shoal Creek Succulents. The flower bud unfortunately fizzled. Same happened to the last one just before it rotted. I hope it's not a bad sign.
