Dryandra ser. Capitellatae

Dryandra" ser. "Capitellatae 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 from the Latin "capitulum" ("head") and "-ella" (the feminine diminutive), in reference to the small flower heads. It was defined as containing two species, "D. serratuloides" (now "Banksia serratuloides") and "D. meganotia" (now "Banksia meganotia"), the former being designated the type species of the series. Both species small lignotuberous shrubs with small flower heads, short leaves, and very small elliptical follicles.
George's placement and circumscription of "D." ser. "Capitellatae", with 1999 and 2005 amendments, 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. "Capitellatae" is no longer current. Mast and Thiele have foreshadowed publishing a full arrangement once DNA sampling of "Dryandra" is complete.
