Taxonomy and naming
This species was first formally described in 1904 by Ludwig Diels who gave it the name Dryandra purdieana and published the description in the journal Botanische Jahrbücher für Systematik, Pflanzengeschichte und Pflanzengeographie.[3][4] The specific epithet (purdieana) honours Diels's friend Alexander Purdie.[4][5]
In 2007 Austin Mast and Kevin Thiele transferred all dryandras to the genus Banksia and renamed this species Banksia purdieana.[6][7]
