According To George
Bentham's arrangement stood until 1996, when Alex George published his revision of Dryandra. George transferred D. carduacea (which was then named D. squarrosa subsp. squarrosa) and D. polycephala into D. ser. Armatae, and placed D. carlinoides and D. kippistiana in D. ser. Acrodontae. This left only D. floribundae (which was then named D. sessilis) in D. ser. Floribundae. The series was defined in terms of the distinguishing characteristics of D. sessilis; for example it was noted that "the apparent absence of floral bracts is unique in the genus."
George's placement and circumscription of D. ser. Floribundae, as amended in 1999 and 2005, may be summarised as follows:
