Nomenclatural adjustments in African plants 2

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.
