Dryandra ser. Niveae is an obsolete series within the former genus Dryandra (now Banksia ser. Dryandra). It was first published by George Bentham in 1870, and was given a new circumscription by Alex George in 1996, but was ultimately discarded in 2007 when Austin Mast and Kevin Thiele sunk Dryandra into Banksia .
Bentham's definition of D. ser. Niveae was "Flowering stems from a creeping trunk very short, with one or few ovoid flower-heads surrounded by long floral leaves. Leaves pinnate with numerous rigid segments white underneath except in D. nana." Four species were included; the placement and circumscription of the series may be summarised as follows: [1]
With the passage of time following the publication of Bentham's arrangement, D. ser. Niveae was gradually abandoned. As the flowers and fruit are highly similar across all species in the series, it is difficult to distinguish individual species. For this reason the name Dryandra nivea began to be used in a broad sense, to refer to the entire group, and the other species names fell into disuse.
When Alex George published his revision of Dryandra in 1996, he recognised that there were several taxa in the series, and that these could be distinguished by their leaf shape. He resurrected a number of abandoned names, and published some new species and varieties. A new circumscription was given for the series: essentially the series was defined as containing those species in which the flowers of a flower head form a circle about a central hole. [2]
George's placement and circumscription of D. ser. Niveae, as amended in 1999 [3] and 2005, [4] may be summarised as follows:
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. Niveae is no longer current. Mast and Thiele have foreshadowed publishing a full arrangement once DNA sampling of Dryandra is complete. [8]
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.
Banksia ser. Abietinae is a valid botanic name for a series of Banksia. First published by Carl Meissner in 1856, the name has had three circumscriptions.
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.
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.
Banksia ser. Cyrtostylis is a taxonomic series within the plant genus Banksia. First published at sectional rank by George Bentham in 1870, it was demoted to a series by Alex George in 1981. The name has had three circumscriptions.
Banksia ser. Banksia is a valid botanic name for a series of Banksia. As an autonym, it necessarily contains the type species of Banksia, B. serrata. Within this constraint, however, there have been various circumscriptions.
Banksia acuminata is a rare prostrate shrub endemic to south-west Western Australia. It was published in 1848 as Dryandra preissii, but transferred into Banksia as B. acuminata in 2007.
Dryandra subg. Diplophragma is an obsolete subgenus within the former genus Dryandra. It was first published by Robert Brown in 1830, 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 sank Dryandra into 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.
George Bentham's taxonomic arrangement of Dryandra was published in 1870, in Volume 5 of Bentham's Flora Australiensis. It replaced the 1856 arrangement of Carl Meissner, and stood for over a century before being replaced by the 1996 arrangement of Alex George.
Carl Meissner's taxonomic arrangement of Dryandra, now Banksia ser. Dryandra, was published in 1856 as part of his chapter on the Proteaceae in A. P. de Candolle's Prodromus systematis naturalis regni vegetabilis. It replaced the 1830 arrangement of Robert Brown, and remained current until superseded by the 1870 arrangement of George Bentham.
Dryandra subg. Dryandra is an obsolete clade of plant. It was a series within the former genus Dryandra. The name was first published at sectional rank as Dryandra verae in 1830, before being renamed Eudryandra in 1847, the replaced by the autonym at subgenus rank in 1996. It was ultimately discarded in 2007 when Austin Mast and Kevin Thiele sunk Dryandra into Banksia.
Dryandra ser. Floribundae is an obsolete series within the former genus Dryandra. It was first published by George Bentham in 1870, and was given a new circumscription by Alex George in 1996, but was ultimately discarded in 2007 when Austin Mast and Kevin Thiele sunk Dryandra into Banksia.
Dryandra ser. Armatae is an obsolete series within the former genus Dryandra. It was first published by George Bentham in 1870, and was given a new circumscription by Alex George in 1996, but was ultimately discarded in 2007 when Austin Mast and Kevin Thiele sunk Dryandra into Banksia.
Banksia dallanneyi subsp. media is a subspecies of Banksia dallanneyi. It was known as Dryandra lindleyana subsp. media until 2007, when Austin Mast and Kevin Thiele sunk all Dryandra into Banksia. Since there was already a Banksia named Banksia lindleyana, Mast and Thiele had to choose a new specific epithet for D. lindleyana and hence for this subspecies of it. As with other members of Banksia ser. Dryandra, it is endemic to the South West Botanical Province of Western Australia.
Dryandra ser. Ilicinae is an obsolete series within the former genus 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.
Dryandra ser. Plumosae is an obsolete series within the former genus Dryandra. It was published by Alex George in 1996, but discarded in 2007 when Austin Mast and Kevin Thiele sank Dryandra into Banksia.
Dryandra ser. Capitellatae is an obsolete series within the former genus Dryandra. It was published by Alex George in 1996, but discarded in 2007 when Austin Mast and Kevin Thiele sank Dryandra into Banksia.
Dryandra ser. Aphragma is an obsolete series within the former genus Dryandra. It was first published at sectional rank by Robert Brown in 1830, and was retained at that rank until 1999, when Alex George demoted it to a series. It was discarded in 2007 when Austin Mast and Kevin Thiele sank Dryandra into Banksia.
