Recent Developments
Since 1998, Austin Mast has been publishing results of ongoing cladistic analyses of DNA sequence data for the subtribe Banksiinae. His analyses suggest a phylogeny that is rather different to previous taxonomic arrangements. Although B. subser. Banksia is monophyletic, it is only distantly related to the other taxa in B. ser. Banksia, being most closely related to B. ser. Ochraceae and B. ser. Prostratae.
Early in 2007 Mast and Thiele initiated a rearrangement of Banksia by transferring Dryandra into it, and publishing B. subg. Spathulatae for the species having spoon-shaped cotyledons. All members of subseries Banksia fall within Mast and Thiele's B. subg. Banksia, but no further details have been published. Mast and Thiele have foreshadowed publishing a full arrangement once DNA sampling of Dryandra is complete.

Famous quotes containing the word developments:
“I don’t wanna live in a city where the only cultural advantage is that you can make a right turn on a red light.
Freedom from labor itself is not new; it once belonged among the most firmly established privileges of the few. In this instance, it seems as though scientific progress and technical developments had been only taken advantage of to achieve something about which all former ages dreamed but which none had been able to realize.”
—Hannah Arendt (1906–1975)
“The developments in the North were those loosely embraced in the term modernization and included urbanization, industrialization, and mechanization. While those changes went forward apace, the antebellum South changed comparatively little, clinging to its rural, agricultural, labor-intensive economy and its traditional folk culture.”
—C. Vann Woodward (b. 1908)
