Banksia ser. Quercinae is a valid botanic name for a series of Banksia . First published by Carl Meissner in 1856, the name has had three circumscriptions.

Contents

According to Meissner

B. ser. Quercinae was first published in 1856, in Carl Meissner'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 Quercinae containing the species with strongly dentate, cuneate to obovate leaves. [1] As they were defined on leaf characters alone, all of Meissner's series were highly heterogeneous. [2]

The placement and circumscription of B. ser. Quercinae in Meissner's arrangement may be summarised as follows: [1]

Banksia
B. sect. Eubanksia
B. ser. Abietinae (8 species, 1 variety)
B. ser. Salicinae (23 species, 8 varieties)
B. ser. Quercinae
B. coccinea
B. sceptrum
B. Baueri
B. ornata
B. latifolia (now B. robur )
B. marcescens (now B. praemorsa )
B. oblongifolia
B. serrata
B. æmula
B. Caleyi
B. caleyi var. sinuosa (now B. caleyi )
B. Lemanniana
B. quercifolia
B. dentata
B. prostrata (now B. gardneri )
B. Goodii
B. barbigera
B. repens
B. Solandri
B. solandri var. major (now B. solandri )
B. ser. Dryandroideae (8 species)
B. sect. Isostylis (1 species)

Meissner's arrangement was current until 1870, when George Bentham published his arrangement, discarding all four of Meissner's series. [3]

According to George

In 1981, Alex George published a thorough revision of Banksia in his classic monograph The genus Banksia L.f. (Proteaceae) . He reinstated B. ser. Quercinae, placing it within B. sect. Banksia, and redefining it as containing those species with awned perianths, and beaked follicles. Initially, the series contained three species, [2] but in 1988 George moved B. baueri (Woolly Orange Banksia) into its own series, B. ser. Bauerinae, [4] leaving just B. quercifolia (Oak-leaved Banksia) and B. oreophila (Western Mountain Banksia) in B. ser. Quercinae.

The placement and circumscription of B. ser. Quercinae in George's taxonomic arrangement of Banksia may be summarised as follows: [5]

Banksia
B. subg. Banksia
B. sect. Banksia
B. ser. Salicinae (11 species, 7 subspecies)
B. ser. Grandes (2 species)
B. ser. Banksia (8 species)
B. ser. Crocinae (4 species)
B. ser. Prostratae (6 species, 3 varieties)
B. ser. Cyrtostylis (13 species, 2 subspecies)
B. ser. Tetragonae (3 species)
B. ser. Bauerinae (1 species)
B. ser. Quercinae
B. quercifolia
B. oreophila
B. sect. Coccinea (1 species)
B. sect. Oncostylis (3 series, 22 species, 4 subspecies, 11 varieties)
B. subg. Isostylis (3 species)

According to Thiele and Ladiges

In 1996, Kevin Thiele and Pauline Ladiges undertook a cladistic analysis of morphological characters of Banksia, which yielded a phylogeny somewhat at odds with George's taxonomic arrangement. B. ser. Quercinae was found to be monophyletic, though quite closely related to B. ser. Spicigerae. They therefore retained the series, placing it next to B. ser. Spicigerae in their arrangement. [6]

The placement and circumscription of B. ser. Quercinae in Thiele and Ladiges' arrangement may be summarised as follows: [6]

Banksia
B. subg. Isostylis (3 species)
B. elegans (incertae sedis)
B. subg. Banksia
B. ser. Tetragonae (4 species)
B. ser. Lindleyanae (1 species)
B. ser. Banksia (2 subseries, 12 species)
B. baueri (incertae sedis)
B. lullfitzii (incertae sedis)
B. attenuata (incertae sedis)
B. ashbyi (incertae sedis)
B. coccinea (incertae sedis)
B. ser. Prostratae (8 species)
B. ser. Cyrtostylis (4 species)
B. ser. Ochraceae (3 species, 2 subspecies)
B. ser. Grandes (2 species)
B. ser. Salicinae (2 subseries, 11 species, 4 subspecies)
B. ser. Spicigerae (3 subseries, 7 species, 6 varieties)
B. ser. Quercinae
B. quercifolia
B. oreophila
B. ser. Dryandroideae (1 species)
B. ser. Abietinae (4 subseries, 15 species, 8 varieties)

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. Quercinae, George's 1999 arrangement was no different from that of 1988. [5]

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 very greatly different from George's taxonomic arrangement, including finding Banksia to be paraphyletic with respect to Dryandra . With respect to B. ser. Quercinae, however, Mast's analysis concurs with previous arrangements, placing its two species alone in a clade that is fairly widely separated from other clades. [7] [8] [9]

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. 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. [10]

Taxonomy of <i>Banksia</i> Classification of the plant genus Banksia

As with other flowering plants, the taxonomy of Banksia has traditionally been based on anatomical and morphological properties of the Banksia flower, fruiting structure and seed, along with secondary characteristics such as leaf structure and growth habit. Increasingly, molecular evidence from DNA is providing important new insights into relationships within the genus and between this and other genera in the Proteaceae.

Flowering occurs in late summer, after which time the flower spikes age and turn to brown and then grey, and develop up to 70 follicles. It occurs in the vicinity of Kalbarri, Western Australia. Found on sandy soils, the plant serves as a pollinator for a variety of bird and animal species.

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. It replaced Alex George's 1981 arrangement, but most aspects were not accepted by George, and it was soon replaced by a 1999 revision of George's arrangement. However some herbaria have continued to follow Thiele and Ladiges on some points.

Alex George's taxonomic arrangement of Banksia was the first modern-day arrangement for that genus. First published in 1981 in the classic monograph The genus Banksia L.f. (Proteaceae), it superseded the arrangement of George Bentham, which had stood for over a hundred years. It was overturned in 1996 by Kevin Thiele and Pauline Ladiges, but restored by George in 1999. A recent publication by Austin Mast and Kevin Thiele suggests that it will soon be overturned again.
