Dryandra ser. Plumosae

Dryandra" ser. "Plumosae is an obsolete series within the former genus "Dryandra" (now "Banksia" ser. "Dryandra"). It was published by Alex George in 1996, but discarded in 2007 when Austin Mast and Kevin Thiele sank "Dryandra" into "Banksia".
Publication.
George published the series in his 1996 "New taxa and a new infrageneric classification in "Dryandra" R.Br.", naming it after the type species, "D. plumosa" (now "Banksia plumosa"). It was defined as containing three species, "D. plumosa", "D. pseudoplumosa" (now "B. pseudoplumosa") and "D. montana" (now "B. montana". All three species are dense bushy shrubs, without a lignotuber; and all have long hairs on the stems and about the flower heads. In addition, all three are restricted to western parts of the Esperance Plains region of Western Australia, between the Stirling Range and the Fitzgerald River region.
George's placement and circumscription of "D." ser. "Plumosae", as amended in his 1999 treatment of "Dryandra" for the "Flora of Australia" series, and in 2005, may be summarised as follows:
Abandonment.
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". This transfer necessitated the setting aside of George's infrageneric arrangement of "Dryandra"; thus "D." ser. "Plumosae" is no longer current. Mast and Thiele have foreshadowed publishing a full arrangement once DNA sampling of "Dryandra" is complete.
