Banksia ser. Salicinae
Encyclopedia
Banksia ser. Salicinae is a valid botanic name for a series
of Banksia
. First published by Carl Meissner
in 1856, the name has had three circumscriptions.
's chapter on the Proteaceae
in A. P. de Candolle
's Prodromus systematis naturalis regni vegetabilis
. It was one of four series into which the subgenus Eubanksia was divided. These four series were defined in terms of leaf characters, with series Salicinae containing the species with linear, or nearly so, leaves with hoary grey undersides. As they were defined on leaf characters alone, all of Meissner's series were highly heterogeneous.
The placement and circumscription of B. ser. Salicinae in Meissner's arrangement
may be summarised as follows:
Meissner's arrangement was current until 1870, when George Bentham
published his arrangement
, discarding all four of Meissner's series.
published a thorough revision of Banksia in his classic monograph The genus Banksia L.f. (Proteaceae)
. He reinstated B. ser. Salicinae, placing it within B. sect. Banksia
, and defining it as containing only those species with entire, serrate or dentate leaves; a small pollen-presenter
; and unbeaked follicle
s.
The placement and circumscription of B. ser. Abietinae in George's taxonomic arrangement of Banksia
may be summarised as follows:
In a later publication, George would refer to this series by the name B. ser. Banksiae, but this is probably a typographical error, as the name has not been validly published.
In 1991, the Tasmania
n fossil taxon B. kingii
was placed in this series.
and Pauline Ladiges undertook a cladistic
analysis of morphological
characters of Banksia, which yielded a phylogeny somewhat at odds with George's taxonomic arrangement. They found George's B. ser. Salicinae to be monophyletic
, their cladogram
placing it in a clade
whose sister clade consisted of the members of George's B. ser. Quercinae
and B. ser. Spicigerae
:
Thiele and Ladiges therefore retained George's B. ser. Salicinae, further dividing it into two subseries, B. subser. Acclives and B. subser. Integrifoliae, in accordance with the resolution of clades in their analysis. The placement and circumscription of B. ser. Abietinae in Thiele and Ladiges' arrangement
may be summarised as follows:
Thiele and Ladiges' arrangement remained current only until 1999, when George's treatment of the genus for the Flora of Australia
series of monographs was published. This was essentially a revision of George's 1981 arrangement, which took into account some of Thiele and Ladiges' data, but rejected their overall arrangement. With respect to B. ser. Abietinae, George's 1999 arrangement was fundamentally the same as his 1981, but differed in the ranking of some taxa, the inclusion of some newly published taxa, and changes to the phyletic order.
has been publishing results of ongoing cladistic analyses of DNA sequence
data for the subtribe Banksiinae. His analyses suggest a phylogeny that is very greatly different to George's taxonomic arrangement, including finding Banksia to be paraphyletic
with respect to Dryandra
. Mast's analyses did not include either subspecies of B. conferta
(Glasshouse Banksia), but otherwise found B. ser. Salicinae to be monophyletic. The clade is not very well resolved, however, having a number of polytomies
:
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 cotyledon
s; in this way they also redefined the autonym
B. subg. Banksia
as containing those taxa lacking spoon-shaped cotyledons. The members of B. ser. Quercinae fall within B. subg. Spathulatae, but no further details have been proffered. Mast and Thiele have foreshadowed publishing a full arrangement once DNA sampling of Dryandra is complete.
. The exception, B. dentata
(Tropical Banksia) spreads across the north of Australia to the Kimberleys, and also occurs on
New Guinea
and the Aru Islands
.

Banksia ser. Spicigerae
Banksia ser. Spicigerae is a taxonomic series in the genus Banksia. It consists of the seven species in section Oncostylis that have cylindrical inflorescences. These range in form from small shrubs to tall trees. The leaves grow in either an alternate or whorled pattern, with various shape forms...

Thiele and Ladiges therefore retained George's B. ser. Salicinae, further dividing it into two subseries, B. subser. Acclives and B. subser. Integrifoliae, in accordance with the resolution of clades in their analysis. The placement and circumscription of B. ser. Abietinae in Thiele and Ladiges' arrangement
Thiele and Ladiges' taxonomic arrangement of Banksia
Kevin Thiele and Pauline Ladiges' taxonomic arrangement of Banksia, published in 1996, was a novel taxonomic arrangement that was intended to align the taxonomy of Banksia more closely with the phylogeny that they had inferred from their cladistic analysis of the genus...
may be summarised as follows:
- BanksiaBanksiaBanksia is a genus of around 170 species in the plant family Proteaceae. These Australian wildflowers and popular garden plants are easily recognised by their characteristic flower spikes and fruiting "cones" and heads. When it comes to size, banksias range from prostrate woody shrubs to trees up...

With respect to B. ser. Abietinae, George's 1999 arrangement was fundamentally the same as his 1981, but differed in the ranking of some taxa, the inclusion of some newly published taxa, and changes to the phyletic order.
