Banksia subulata
''Banksia subulata'', commonly known as Awled Honeypot, is a shrub endemic to Western Australia.
==Taxonomy==
It was first published as ''Dryandra subulata'' by Charles Gardner in 1964. In Alex George's 1996 arrangement, this species was recognised as quite distinctive, being unusual in its long, unserrated leaves, its rigid awl-shaped floral leaves, and its round follicles. With no obvious relatives, the species was placed alone in a new series named ''Dryandra'' ser. ''Subulatae''.
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; ''Dryandra subulata'' thus became ''Banksia subulata''. Interestingly, Mast's analyses placed ''B. subulata'' not with the other ''Dryandra'' species sampled, but rather within a small clade of ''Banksia'' species with independently reduced inflorescence axes. For this reason, ''B. subulata'' was placed ''incertae sedis'' in ''B.'' subg. ''Banksia'', rather than in ''B.'' ser. ''Dryandra'' with the other ''Dryandra'' species.
The transfer of ''Dryandra'' into ''Banksia'' necessitated the setting aside of George's infrageneric arrangement of ''Dryandra''; thus ''D.'' ser. ''Subulatae'' is no longer current. Mast and Thiele have foreshadowed publishing a full arrangement once DNA sampling of ''Dryandra'' is complete.〔
