Banksia splendida subsp. macrocarpa
Banksia splendida" subsp. "macrocarpa is a subspecies of "Banksia splendida". It was known as Dryandra speciosa" subsp. "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. As with other members of "Banksia" ser. "Dryandra", it is endemic to the South West Botanical Province of Western Australia.
