The transfer of Dryandra R.Br. to Banksia L.f. (Proteaceae)

The transfer of Dryandra R.Br. to Banksia L.f. (Proteaceae) Phylogenies inferred from both chloroplast and nuclear DNA regions have placed the south-west Australian genus Dryandra R. Br. (93 spp.) among the descendents of the most recent common ancestor of the more widespread Australian genus Banksia L.f. (80 spp.). Here we consider the alternative solutions to maintaining monophyly at the generic rank and choose to make new combinations and replacement names for Dryandra in Banksia . We make the new combination Banksia ser. Dryandra in Banksia subgen. Banksia for 108 of the 109 new combinations at the ranks of species, subspecies, and variety and all 18 of the replacement names. We treat Banksia subgen. Banksia as the most inclusive clade that includes the type of Banksia ( B. serrata ) but not B. integrifolia . We erect Banksia subgen. Spathulatae to accommodate the species in the most inclusive clade that includes B. integrifolia but not B. serrata . These two subgenera of Banksia are equivalent to the clades informally called / Cryptostomata and / Phanerostomata elsewhere.

Abstract

Phylogenies inferred from both chloroplast and nuclear DNA regions have placed the south-west Australian genus Dryandra R. Br. (93 spp.) among the descendents of the most recent common ancestor of the more widespread Australian genus Banksia L.f. (80 spp.). Here we consider the alternative solutions to maintaining monophyly at the generic rank and choose to make new combinations and replacement names for Dryandra in Banksia . We make the new combination Banksia ser. Dryandra in Banksia subgen. Banksia for 108 of the 109 new combinations at the ranks of species, subspecies, and variety and all 18 of the replacement names. We treat Banksia subgen. Banksia as the most inclusive clade that includes the type of Banksia ( B. serrata ) but not B. integrifolia . We erect Banksia subgen. Spathulatae to accommodate the species in the most inclusive clade that includes B. integrifolia but not B. serrata . These two subgenera of Banksia are equivalent to the clades informally called / Cryptostomata and / Phanerostomata elsewhere. We treat one of the new combinations, Banksia subulata , as incertae sedis within Banksia subgen. Banksia .
