In preparation for the treatment of Arctotis L. (Asteraceae) in the e-Flora of South Africa project, the correct names, typifications and synonymies are clarified for 24 Arctotis species and two varieties indigenous to the Western Cape and Eastern Cape provinces of South Africa. Lectotypes are designated for 36 names and neotypes for two names. The names A. glabrata Jacq., A. paniculata Jacq. and A. spinulosa Jacq. are resurrected for poorly known, apparently geographically restricted species. Arctotis roodae Hutch. is the correct name at specific rank for the taxon previously known as A. campanulata var. puberula DC. Arctotis laciniata Lam. is the earliest legitimate name for an element of the A. aspera species complex, to which the name A. revoluta Jacq. has often been applied. The name A. revoluta Jacq. correctly applies to a distinct, unrelated species, for which a revised synonymy is presented. A lectotype is designated for the illegitimate name A. undulata Jacq., the earliest legitimate name for which is A. acaulis var. undulata Less.
