other members of D. sect. Niveae, he placed D. preissii in that series. This placement was only tentative, however, as he had not been able to example any fruiting specimens. A synonym, Josephia preissii, arises from Otto Kuntze's 1891 transfer of the genus Dryandra (now Banksia ser. Dryandra) into Josephia, on the grounds that Josephia Knight had priority over Dryandra R.Br.. This transfer was rejected. In 1996, Alex George published the first modern-day arrangement of Dryandra. He placed D. preissii alone in a new series, Dryandra ser. Acuminatae, named from the Latin acuminatus ("tapering to a protracted point") in reference to the unusual involucral bracts. The placement of D. preissii in George's arrangement of Dryandra, with 1999 and 2005 amendments, may be summarised as follows: Dryandra (now Banksia ser. Dryandra) D. subg. Dryandra D. ser. Floribundae (1 species, 4 varieties) D. ser. Armatae (21 species, 7 subspecies, 4 varieties) D. ser. Marginatae (1 species) D. ser. Folliculosae (1 species, 5 varieties) D. ser. Acrodontae (4 species, 2 varieties) D. ser. Capitellatae (2 species, 2 subspecies) D. ser. Ilicinae (3 species, 2 varieties) D. ser. Dryandra (3 species, 2 subspecies) D. ser. Foliosae (3 species, 2 subspecies) D. ser. Decurrentes (1 species) D. ser. Tenuifoliae (2 species, 2 varieties) D. ser. Runcinatae (4 species, 7 subspecies) D. ser. Triangulares (3 species, 3 subspecies) D. ser. Aphragma (9 species, 3 subspecies) D. ser. Ionthocarpae (1 species, 2 subspecies) D. ser. Inusitatae (1 species) D. ser. Subulatae (1 species) D. ser. Gymnocephalae (11 species, 4 subspecies, 2 varieties) D. ser. Plumosae (3 species, 2 subspecies) D. ser. Concinnae (3 species) D. ser. Obvallatae (7 species, 2 varieties) D. ser. Pectinatae (1 species) D. ser. Acuminatae D. preissii (now Banksia acuminata) D. ser. Niveae D. subg. Hemiclidia (2 species) D. subg. Diplophragma (1 species) George's arrangement remained current until February 2007, when Austin Mast and Kevin Thiele transferred Dryandra into Banksia. As the name Banksia preissii had already been published by Otto Kuntze for the plant now known as Pimelea preissii, Mast and Thiele were forced to choose a new specific epithet; their choice, "acuminata", was for the same reasons as George's D. ser. Acuminatae. Mast and Thiele also published B. subg. Spathulatae for the Banksia taxa having spoon-shaped cotyledons, thus redefining B. subg. Banksia as comprising those that do not. They were not ready, however, to tender an infrageneric arrangement encompassing Dryandra, so
