Abstract
SummaryMorphological character data are used to show that a distinct morphotype of Dioscorea L. from KwaZulu-Natal in South Africa is an undescribed species, related to the D. buchananii Benth. species complex but differing in its inflorescence and floral morphology from all other taxa. It is described as Dioscorea hurteri R. Hills & Wilkin, illustrated and a distribution map and ecological information provided. It is known from four localities, just two of which may be protected, within a heavily developed region of South Africa and with an extent of occurrence (EOO) of 9,872 km2. Thus, its provisional IUCN conservation status is vulnerable (VU).
