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.
