Abstract [en]

In a recent floristic treatment, Haplocarpha thunbergii Less. was considered to be the correct name for H. scaposa Harv. The name H. thunbergii is a substitute name for Arctotis lanata Thunb. Examination of the original material in the Thunberg herbarium proved that Thunberg based the name A. lanata on three specimens each belonging to different species (those currently known as A. acaulis L., H. lanata Less. and H. parvifolia (Schltr.) Beauverd). Our identifications of these specimens proved that the names A. lanata and H. scaposa are not conspecific and H. scaposa is not a homotypic synonym of H. thunbergii. Herein a lectotype for H. scaposa is designated from the syntypes specified by Harvey. With the objective of maintaining nomenclatural stability, we lectotypify A. lanata and place it in synonymy of A. acaulis, thus preserving usage of the name H. parvifolia. An updated synonymy for A. acaulis is provided. In addition, lectotypes are designated for A. fosteri N.E. Br., A. oocephala DC., A. parvifolia Schltr., H. lyrata Harv. and H. transvaalensis Gand.
