Tylecodon ectypus, a New Cliff Dwelling Species from the Skaaprivier, Northern Namaqualand (Northern Cape Province), South Africa

Abstract: Tylecodon ectypus (Crassulaceae) is a new species originating from the upper reaches of the Skaaprivierspoort, west of Steinkopf (northern Namaqualand). It is at once distinguished by its geophytic growth form, orbicular glossy leaves bearing thick reticulated veins, candelabriform inflorescences and trumpet-shaped pink-striped white corolla. Vulnerable status (IUCN red list criteria) is justified by its restricted and fragmented distribution, especially considering its scarcity in two of the three known populations.
