Dryandra ser. Aphragma

It was discarded in 2007 when Austin Mast and Kevin Thiele sank Dryandra into Banksia.

Aphragma was first published by Brown in his 1830 Supplementum primum prodromi florae Novae Hollandiae.

Aphragma in Brown's 1830 arrangement may be summarised as follows: In 1856, Carl Meissner published a revision of Dryandra.

Aphragma was retained by George Bentham in his 1870 arrangement, making it the only one of Meissner's infrageneric taxa not to be discarded.

Aphragma was redefined as containing those species in which "Outer integuments of the two seeds not connate or readily separable from each other."

He also noted that the members of this section have large involucres with many broad bracts, giving them "a different aspect from all others of the genus".

Aphragma in George's arrangement, as amended in 1999[7] and 2005,[8] may be summarised as follows: Since 1998, Austin Mast has been publishing results of ongoing cladistic analyses of DNA sequence data for the subtribe Banksiinae.

[9][10][11] Early in 2007, Mast and Kevin Thiele initiated a rearrangement of Banksia by sinking Dryandra into it as B. ser.

Mast and Thiele have foreshadowed publishing a full arrangement once DNA sampling of Dryandra is complete.
