Widdringtonia nodiflora (L.) Powrie, known as Cape Cypress, is a species in the Cupressaceae family. It is native to Southern Africa, including regions such as the Cape Provinces, Free State, KwaZulu-Natal, Lesotho, Malawi, Mozambique, Northern Provinces, and Zimbabwe. The species is typically found at high altitudes, often on rocky mountainsides. Its foliage and wood are highly flammable, and the plant regenerates through coppicing from its roots after fires. The taxonomic status of the name has been subject to discussion, with some uncertainty in its application. Earlier treatments have raised issues regarding its nomenclatural validity, and it was rejected as a nomen ambiguum by Marsh (1966). Further clarifications were provided by Powrie and Farjon, though the lectotype designation by Farjon is not effective due to the date of publication.
Description
Widdringtonia nodiflora is a conifer species in the Cupressaceae family, commonly known as Cape Cypress. It is native to Southern Africa and is adapted to high-altitude, rocky environments. The plant is fire-prone and regenerates via root coppicing after being burned. The taxonomic history of the name is complex, with earlier treatments by Powrie and Farjon addressing its nomenclatural status. Marsh (1966) rejected the name as a nomen ambiguum, and subsequent discussions have highlighted the uncertainty in its application. The species was originally described by Linnaeus as Brunia nodiflora, and later reclassified under Widdringtonia by Powrie in 1972. Farjon's later work proposed a holotype, but the designation was not effective under the International Code of Nomenclature for algae, fungi, and plants due to the publication date.
