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.{{cite web|title=Dryandra purdieana|url= https://id.biodiversity.org.au/instance/apni/529217|publisher=APNI|access-date=26 May 2020}}{{cite journal |last1=Diels |first1=Ludwig |title=Fragmenta Phytographiae Australiae occidentalis.
