Hydnora visseri
Also called Sweet Thorn Jackalskos
Hydnora visseri, the Visser's hydnora, is a subterranean holoparasitic plant, lacking leaves and roots, and is described from southwestern Namibia and northwestern South Africa and has the longest tepal lobes of all Hydnora species. The genus Hydnora is composed entirely of holoparasitic plants that attach to the root of their hosts and are restricted to Africa and southwestern Asia.
Hydnora visseri grows in the winter rainfall and transitional rainfall areas of the Karas Region of Namibia and the Northern Cape province of South Africa. It occurs in a limited distribution centred around the Orange River, and is only present where its hosts Euphorbia gummifera and E. gregaria are present. H. visseri does not occur in the Karoo, nor a Karoo-type habitat, but is present in a region which the WWF has called the Succulent-Karoo and/or Nama-Karoo biomes. Hydnora visseri is most easily located by searching in around the base of the host Euphorbia plants.
