Taxonomic Notes on the New Zealand flora: Brachyscome simplicifolia JBArmstr. is a heterotypic synonym of Abrotanella linearis Berggr. (Asteraceae)

Brachyscome simplicifolia J.B.Armstr. was treated as incertae sedis by H.H. Allan in the Flora of New Zealand, Volume 1, published in 1961. At that time, H.H. Allan, along with the earlier flora writers T. Kirk and T.F. Cheeseman, had not seen herbarium material referable to that name. An authentic herbarium specimen from the Armstrong Herbarium, formally part of the Christchurch Botanic Gardens Herbarium (CHBG) but now housed at the Allan Herbarium (CHR), has been located and is designated as lectotype for B. simplicifolia. Based on this lectotypification, B. simplicifolia is conspecific with Abrotanella linearis Berggr., and being the more recently published name is treated as a heterotypic synonym.
