Banksia splendida subsp.

macrocarpa is a subspecies of Banksia splendida.

macrocarpa until 2007, when Austin Mast and Kevin Thiele sunk all Dryandra into Banksia.

Since there was already a species named Banksia speciosa, Mast and Thiele had to choose a new specific epithet for D. speciosa and hence for this subspecies of it.

Dryandra, it is endemic to the South West Botanical Province of Western Australia.
