Typification and application of the name Arctotis grandiflora Aiton (Asteraceae: Arctotideae)

Abstract

Background: Ongoing taxonomic studies in the African genus Arctotis (Asteraceae) necessitate periodic nomenclatural adjustments and corrections.Objectives: To evaluate the taxonomic status and application of the name Arctotis grandiflora Aiton.Methods: Type material and herbarium specimens were located and examined, relevant literature was consulted and wild populations were observed.Results: The type material of A. grandiflora Aiton comprises specimens of two taxa from independent gatherings. A lectotype is designated for A. grandiflora.Conclusion: The name A. grandiflora Aiton is a heterotypic synonym of Arctotis stoechadifolia P.J.Bergius. A revised synonymy for A. stoechadifolia is presented.

“…Given the valid publication of the name, either resolution of its application and taxonomic status or formal rejection of the name is necessary. As part of an ongoing revision of the nomenclature and taxonomy of Arctotis (e.g., McKenzie & al., 2008a,b; McKenzie & Barker, 2010; McKenzie, 2018a,b, 2019; McKenzie & Nepi, 2019), the status and potential typification of Arctotis radicans were assessed in the present study.…”
