Dryandra ser. Ilicinae is an obsolete series within the former genus Dryandra (now Banksia ser. Dryandra). It was first published by Carl Meissner in 1856, but was discarded by George Bentham in 1870. It was reinstated with a new circumscription by Alex George in 1996, but was ultimately discarded again in 2007 when Austin Mast and Kevin Thiele sunk Dryandra into Banksia .

According to Meissner

This taxon was first published by Meissner in his 1856 chapter on the Proteaceae in A. P. de Candolle's Prodromus systematis naturalis regni vegetabilis .. Meissner's arrangement followed that of Robert Brown in segregating a single species into the genus Hemiclidia , and dividing the remaining species into three sections according to what were perceived to be variations in the number of seed separators. Meissner then further divided D. sect. Eudryandra into eight unranked groups signified by the symbol "§". The first of these, Dryandra § Ilicinae, was defined as comprising four species with leaves resembling those of Ilex (Holly). The placement and circumscription of D. § Ilicinae in Meissner's arrangement thus looks like this: [1]

Dryandra (now Banksia ser. Dryandra)
D. sect. Eudryandra (8 series, 47 species, 7 varieties)
D. § Ilicinae
D. praemorsa (now B. undata )
D. praemorsa var. elongata (now B. undata var. undata)
D. quercifolia (now B. heliantha )
D. cuneata (now B. obovata )
D. floribunda (now B. sessilis var. sessilis)
D. floribunda var. cordata (now B. sessilis var. cordata)
D. § Runcinatae (5 species)
D. § Serratae (11 species, 3 varieties)
D. § Marginatae (7 species)
D. § Pectinatae (6 species)
D. § Decurrentes (11 species)
D. § Acrodontae (2 species)
D. § Haplophyllae (1 species)
D. sect. Diplophragma (2 species)
D. sect. Aphragma (4 species, 4 varieties)
Hemiclidia (1 species)

According to Bentham

Along with many of Meissner's infrageneric taxa, which were overly reliant on leaf characters, Bentham discarded D. § Ilicinae in his 1870 arrangement. The species that Meissner placed there were placed together in D. ser. Armatae, except for D. floribunda (now Banksia sessilis ) which Bentham placed in D. ser. Floribundae. [2]

According to George

When Alex George published his revision of Dryandra in 1996, he recycled number of previously published infrageneral names, including Meissner's Ilicinae. George gave it series rank and placed it within D. subg. Dryandra. It was circumscribed as containing three species: D. praemorsa (now B. undata ), D. quercifolia (now B. heliantha ) and D. anatona (now B. anatona ).

George's placement and circumscription of D. ser. Ilicinae, as amended in 1999 [3] and 2005, [4] may be summarised as follows:

Dryandra (now Banksia ser. Dryandra)
D. subg. Dryandra
D. ser. Floribundae (1 species, 4 varieties)
D. ser. Armatae (21 species, 7 subspecies, 4 varieties)
D. ser. Marginatae (1 species)
D. ser. Folliculosae (1 species, 5 varieties)
D. ser. Acrodontae (4 species, 2 varieties)
D. ser. Capitellatae (2 species, 2 subspecies)
D. ser. Ilicinae
D. praemorsa (now B. undata )
D. praemorsa var. praemorsa (now B. undata var. undata)
D. praemorsa var. splendens (now B. undata var. splendens)
D. quercifolia (now B. heliantha )
D. anatona (now B. anatona )
D. ser. Dryandra (3 species, 2 subspecies)
D. ser. Foliosae (3 species, 2 subspecies)
D. ser. Decurrentes (1 species)
D. ser. Tenuifoliae (2 species, 2 varieties)
D. ser. Runcinatae (4 species, 7 subspecies)
D. ser. Triangulares (3 species, 3 subspecies)
D. ser. Aphragma (9 species, 3 subspecies)
D. ser. Ionthocarpae (1 species, 2 subspecies)
D. ser. Inusitatae (1 species)
D. ser. Subulatae (1 species)
D. ser. Gymnocephalae (11 species, 4 subspecies, 2 varieties)
D. ser. Concinnae (3 species)
D. ser. Obvallatae (7 species, 2 varieties)
D. ser. Pectinatae (1 species)
D. ser. Acuminatae (1 species)
D. ser. Niveae (7 species, 7 subspecies)
D. subg. Hemiclidia (2 species)
D. subg. Diplophragma (1 species)

Recent developments

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. [5] [6] [7] Early in 2007, Mast and Kevin Thiele initiated a rearrangement of Banksia by sinking Dryandra into it as B. ser. Dryandra. This transfer necessitated the setting aside of George's infrageneric arrangement of Dryandra; thus D. ser. Armatae is no longer current. Mast and Thiele have foreshadowed publishing a full arrangement once DNA sampling of Dryandra is complete. [8]

Banksia subg. Banksia is a valid botanic name for a subgenus of Banksia. As an autonym, it necessarily contains the type species of Banksia, B. serrata. Within this constraint, however, there have been various circumscriptions.

<i>Banksia lindleyana</i> Species of shrub in the family Proteaceae from Western Australia

Banksia lindleyana, commonly known as the porcupine banksia, is a species of woody shrub in the genus Banksia of the family Proteaceae. It generally grows as a small shrub to 1 m (3 ft) high with long narrow serrated leaves, and bright yellow oval or round inflorescences. 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.

<span class="mw-page-title-main">George's taxonomic arrangement of Dryandra</span> 1996 arrangement of the Australian endemic plant series Dryandra in the genus Banksia

Alex George's taxonomic arrangement of Dryandra was the first modern-day arrangement of that taxon. First published in Nuytsia in 1996, it superseded the arrangement of George Bentham, which had stood for over a hundred years; it would later form the basis for George's 1999 treatment of Dryandra for the Flora of Australia. In accordance with contemporary thinking, George treated Dryandra as a genus, dividing it into three subgenera, the largest of which was divided into 24 series. The arrangement stood until 2007, when Dryandra was transferred into Banksia as B. ser. Dryandra. No alternative has yet been proposed.
