''Banksia ionthocarpa'' is a shrub endemic to Western Australia. It was known as ''Dryandra ionthocarpa'' until 2007. ==Taxonomy== ''B. ionthocarpa'' was first discovered in 1987 by professional seed supplier Peter Luscombe. The following year specimens were collected by both Margaret Pieroni and Alex George. For the next eight years, the species was referred to by the manuscript name ''Dryandra'' sp. Kamballup (M.Pieroni 20/9/1988). In 1996, Alex George formally published the species as ''Dryandra ionthocarpa'', the specific epithet coming from the Greek ''ionthas'' ("shaggy") and ''carpos'' ("fruit"), in reference to the tuft of hair on each follicle. Indeed, George considered the fruit to be so distinctive that he placed it alone in a new series that he named ''Dryandra'' ser. ''Ionthocarpae''. Since 1998, Austin Mast has been publishing results of ongoing cladistic analyses of DNA sequence data for the subtribe Banksiinae. His analyses have provided compelling evidence of the paraphyly of ''Banksia'' with respect to ''Dryandra''; that is, it seems that ''Dryandra'' arose from within the ranks of ''Banksia''. Early in 2007, Mast and Kevin Thiele initiated a rearrangement of ''Banksia'' by sinking ''Dryandra'' into it as ''B.'' ser. ''Dryandra''; ''Dryandra ionthocarpa'' thus became ''Banksia ionthocarpa''. This transfer necessitated the setting aside of George's infrageneric arrangement of ''Dryandra''; thus ''D.'' ser. ''Ionthocarpae'' is no longer current. Mast and Thiele have foreshadowed publishing a full arrangement once DNA sampling of ''Dryandra'' is complete. Two subspecies are recognised, the autonym ''B.'' ionthocarpa'' subsp. ''ionthocarpa'', and ''B.'' ionthocarpa'' subsp. ''chrysophoenix'', first collected by Pieroni in 1999 and published by George in 2005.
