Banksia ser. Salicinae is a taxonomic series in the genus Banksia. It consists a group of the eleven (or twelve) closely related species in section Banksia that have cylindrical inflorescences. These range in form from medium-sized shrubs to tall trees.
The leaves grow in either an alternate or whorled pattern, with various shape forms, the leaf margins may be flat or recurved and entire, dentate or serrate. The Salicinae inflorescence is held erect, subtended by a whorl of branchlets, and loses its regular pattern well before anthesis. The perianth limb is horizontal until anthesis, at which point the perianth opens from underneath. The pollen-presenter is ovoid. The seed wings are not notched.[1]

[edit] Taxa
All but one of the Salicinae are endemic to the east coast of Australia, the remaining taxon, Banksia dentata spreading across the north of Australia to the Kimberleys, and also occurring on New Guinea and the Aru Islands.
[edit] Species and subspecies
Kevin Thiele split the series into two subseries detailed below.[2] Molecular evidence suggests Banksia aquilonia may be more closely related to Banksia plagiocarpa than B. integrifolia.[3] Alex George holds that B. dentata is clearly allied to B. integrifolia, not to the distinctive B. robur.[1]
Finally, the fossil taxon Banksia kingii from Tasmania is a member.
- Subseries Acclives
- Subseries Integrifoliae
[edit] Hybridization
The species are closely related and interbreeding in the wild has been reported between many members including:
- B. paludosa x B. integrifolia
- B. marginata x B. integrifolia
- B. robur x B. oblongifolia
- B. marginata x B. conferta penicillata
- B. conferta conferta x B. integrifolia
