Dryandra Subg. Diplophragma
Dryandra subg. Diplophragma is an obsolete subgenus within the former genus Dryandra (now Banksia ser. Dryandra). It was first published by Robert Brown in 1830, but was discarded by George Bentham in 1870. It was reinstated with a new circumscription by Alex George in 1996, but was ultimately discarded again in 2007 when Austin Mast and Kevin Thiele sunk Dryandra into Banksia.
