Abstract
Background: Ongoing systematic studies in the African flora necessitate periodic nomenclatural adjustments and corrections. Objectives: To effect requisite nomenclatural changes. Method: Relevant literature was surveyed and type material located and examined. Results: Nomenclatural corrections are published in Mairia Nees (Asteraceae) and Psilosiphon Welw. ex Goldblatt J.C.Manning, nom illeg. (Iridaceae). Conclusions: Cineraria purpurata L. (1771) (Asteraceae) is recognised as the earliest name for Mairia hirsuta DC. (1836) and the new combination M. purpurata (L.) J.C.Manning is provided for the species. Psilosiphon Welw. ex Goldblatt J.C.Manning (2015) (Iridaceae) is a later homonym for Psilosiphon Entwisle (1989). The replacement name Afrosolen Goldblatt J.C.Manning is proposed and the necessary new combinations for the 16 taxa currently recognised in the genus are provided.
Highlights
The identity of Cineraria purpurata L. (1771) has remained uncertain until now. It was described by Linnaeus from one of over 200 specimens of Cape plants sent to him by the Governor at the Cape, Rijk Tulbagh (1699–1771), appointed to the post in 1751
Relatively detailed for the time, the description provided by Linnaeus (1771) was certainly not enough to identify the species on its own, and the name was subsequently included by De Candolle (1836) amongst the 11 species of Cineraria that were inadequately known to him
The name disappeared from the botanical literature, and it is not cited by Harvey (1865) in his treatment of the family for the Flora capensis. It reappears as one of the species excluded from Cineraria L. by Cron et al (2006) in their revision of the genus, where they lectotypify it against Tulbagh 44 in the Linnean Herbarium (LINN) but without further comment as to its identity
Summary
The identity of Cineraria purpurata L. (1771) has remained uncertain until now. It was described by Linnaeus from one of over 200 specimens of Cape plants sent to him by the Governor at the Cape, Rijk Tulbagh (1699–1771), appointed to the post in 1751. Linked to a specimen, the application of the name remained uncertain (Jarvis 2007) until we examined the type and recognised it as the species currently known as Mairia hirsuta DC. 2. Afrosolen Goldblatt & J.C.Manning, a new name for Psilosiphon Welw. Ex Goldblatt & J.C.Manning (Iridaceae), with new combinations Was cited in synonymy under Lapeirousia by J.G. Baker (1878), it was validated only by Goldblatt & Manning (2015) and is an illegitimate homonym. New combinations are provided for the species recognized by Goldblatt & Manning (2015).
