Isostylis
''Banksia'' subg. ''Isostylis'' is a subgenus of ''Banksia''. It contains three closely related species, all of which occur only in Southwest Western Australia. Members of subgenus ''Isostylis'' have dome-shaped flower heads that are superficially similar to those of ''B.'' ser. ''Dryandra'', but structurally more like reduced versions of the "flower spikes" characteristic of most other ''Banksia'' taxa. There are three species of ''Banksia'' subg. ''Isostylis'', ''B. ilicifolia'' (holly-leaved banksia), ''B. cuneata'' (matchstick banksia) and ''B. oligantha'' (Wagin banksia). ''B. ilicifolia'' is widely distributed and relatively common, but the other two species are rare and threatened. Description ''Banksia'' subg. ''Isostylis'' shares with ''B.'' ser. ''Dryandra'' the property of having compact, dome-shaped flower heads. Structurally, however, ''Isostylis'' flower heads are quite different from those of ''B.'' ser. ''Dryandra'', ...

Banksia Ilicifolia
''Banksia ilicifolia'', commonly known as holly-leaved banksia, is a tree in the family Proteaceae. Endemic to southwest Western Australia, it belongs to ''Banksia'' subg. ''Isostylis'', a subgenus of three closely related ''Banksia'' species with inflorescences that are dome-shaped heads rather than characteristic ''Banksia'' flower spikes. It is generally a tree up to tall with a columnar or irregular habit. Both the scientific and common names arise from the similarity of its foliage to that of the English holly ''Ilex aquifolium''; the glossy green leaves generally have very prickly serrated margins, although some plants lack toothed leaves. The inflorescences are initially yellow but become red-tinged with maturity; this acts as a signal to alert birds that the flowers have opened and nectar is available. Robert Brown described ''Banksia ilicifolia'' in 1810. Although ''Banksia ilicifolia'' is variable in growth form, with low coastal shrubby forms on the south coast ne ...

Banksia Oligantha
''Banksia oligantha'', commonly known as Wagin banksia, is an endangered species in the plant family Proteaceae endemic to south west Western Australia. It belongs to ''Banksia'' subg. ''Isostylis'', a subgenus of three closely related '' Banksia'' species with dome-shaped heads as inflorescences, rather than characteristic ''Banksia'' flower spikes. A shrub or small tree up to high, it has prickly foliage and pink and cream flowerheads which appear in late Spring (October to December). First collected in 1984 near the wheatbelt town of Wagin, ''Banksia oligantha'' was officially described in 1987 by Australian botanist Alex George. Several scattered populations survive in fragments of remnant bushland in a region which has been mostly cleared for agriculture. It has been listed as Declared Rare Flora by the Western Australian Government. Description ''Banksia oligantha'' grows as a single-trunked small tree or as an erect shrub with few main stems. Reports of its maxim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banksia Cuneata
''Banksia cuneata'', commonly known as matchstick banksia or Quairading banksia, is an endangered species of flowering plant in the family Proteaceae. Endemic to southwest Western Australia, it belongs to ''Banksia'' subg. ''Isostylis'', a sub-genus of three closely related '' Banksia'' species with inflorescences or flower clusters that are dome-shaped heads rather than characteristic ''Banksia'' flower spikes. A shrub or small tree up to high, it has prickly foliage and pink and cream flowers. The common name ''Matchstick Banksia'' arises from the blooms in late bud, the individual buds of which resemble matchsticks. The species is pollinated by honeyeaters (Meliphagidae). Although ''B. cuneata'' was first collected before 1880, it was not until 1981 that Australian botanist Alex George formally described and named the species. There are two genetically distinct population groups, but no recognised varieties. This ''Banksia'' is classified as endangered, surviving in ...

Bentham's Taxonomic Arrangement Of Banksia
George Bentham's taxonomic arrangement of ''Banksia'' was published in 1870, in Volume 5 of Bentham's ''Flora Australiensis''. A substantial improvement on the previous arrangement, it would stand for over a century. It was eventually replaced by Alex George's 1981 arrangement, published in his classic monograph ''The genus Banksia L.f. (Proteaceae)''. Background ''Banksia'' is a genus of around 80 species in the plant family Proteaceae. An iconic Australian wildflower and popular garden plant, they are easily recognised by their characteristic flower spikes and fruiting "cones". They grow in forms varying from prostrate woody shrubs to trees up to 35 metres tall, and occur in all but the most arid areas of Australia. As heavy producers of nectar, they are important sources of food for nectariferous animals such as honeyeaters and honey possum, and they are of economic importance to the nursery and cut flower industries. However they are seriously threatened by a number of p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meissner's Taxonomic Arrangement Of Banksia
Carl Meissner's taxonomic arrangement of ''Banksia'' was published in 1856, as part of his chapter on the Proteaceae in A. P. de Candolle's ''Prodromus systematis naturalis regni vegetabilis''. It was the first attempt to provide an infrageneric classification for the genus, aside from Robert Brown's publication of two subgenera in 1810. Meissner's arrangement stood until 1870, when it was superseded by the arrangement of George Bentham. Meissner's arrangement was an excellent survey of the known species at that time, but his infrageneric taxa were all highly heterogeneous. Background ''Banksia'' is a genus of around 80 species in the plant family Proteaceae. An iconic Australian wildflower and popular garden plant, they are recognised by their flower spikes or domes, and their fruiting "cones". They grow in forms varying from prostrate woody shrubs to trees up to 35 metres tall, and occur in all but the most arid areas of Australia. As heavy producers of nectar, they are im ...

Banksia
''Banksia'' 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. ''Banksias'' range in size from prostrate woody shrubs to trees up to 30 metres (100 ft) tall. They are found in a wide variety of landscapes: sclerophyll forest, (occasionally) rainforest, shrubland, and some more arid landscapes, though not in Australia's deserts. Heavy producers of nectar, ''banksias'' are a vital part of the food chain in the Australian bush. They are an important food source for nectarivorous animals, including birds, bats, rats, possums, stingless bees and a host of invertebrates. Further, they are of economic importance to Australia's nursery and cut flower industries. However, these plants are threatened by a number of processes including land clearing, frequent burning and disease, and a number of species are rare and endan ...

Brown's Taxonomic Arrangement Of Banksia
Robert Brown's taxonomic arrangement of ''Banksia'' was published in his book of 1810, ''Prodromus Florae Novae Hollandiae et Insulae Van Diemen'', and expanded in the supplement to that publication, ''Supplementum Primum Prodromi Florae Novae Hollandiae'', in 1830. It was the first survey of ''Banksia'' species to be published, and included descriptions of a number of previously undescribed species. Background ''Banksia'' is a genus of around 175 species in the plant family Proteaceae.

Subgenus
In biology, a subgenus (plural: subgenera) is a taxonomic rank directly below genus. In the International Code of Zoological Nomenclature, a subgeneric name can be used independently or included in a species name, in parentheses, placed between the generic name and the specific epithet: e.g. the tiger cowry of the Indo-Pacific, ''Cypraea'' (''Cypraea'') ''tigris'' Linnaeus, which belongs to the subgenus ''Cypraea'' of the genus ''Cypraea''. However, it is not mandatory, or even customary, when giving the name of a species, to include the subgeneric name. In the International Code of Nomenclature for algae, fungi, and plants (ICNafp), the subgenus is one of the possible subdivisions of a genus. There is no limit to the number of divisions that are permitted within a genus by adding the prefix "sub-" or in other ways as long as no confusion can result. Article 4 The secondary ranks of section and series are subordinate to subgenus. An example is ''Banksia'' subg. ''Isostyl ...

Rank (botany)
In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family, order, class, phylum, kingdom, domain. While older approaches to taxonomic classification were phenomenological, forming groups on the basis of similarities in appearance, organic structure and behaviour, methods based on genetic analysis have opened the road to cladistics. A given rank subsumes under it less general categories, that is, more specific descriptions of life forms. Above it, each rank is classified within more general categories of organisms and groups of organisms related to each other through inheritance of traits or features from common ancestors. The rank of any ''species'' and the description of its ''genus'' is ''basic''; which means that to identify a particular organism, it is usually not necessary to specify ranks other than these first two.

Carl Meissner
Carl Daniel Friedrich Meissner (1 November 1800 – 2 May 1874) was a Swiss botanist. Biography Born in Bern, Switzerland on 1 November 1800, he was christened Meisner but later changed the spelling of his name to Meissner. For most of his 40-year career he was Professor of Botany at University of Basel. He made important contributions to the botanical literature, including the publication of the comprehensive work ''Plantarum Vascularum Genera'', and publications of monographs on the families Polygonaceae (especially the genus '' Polygonum''), Lauraceae, Proteaceae, Thymelaeaceae and Hernandiaceae. His contributions to the description of the Australian flora were prolific; he described hundreds of species of Australian Proteaceae, and many Australian species from other families, especially Fabaceae, Mimosaceae and Myrtaceae. His health deteriorated after 1866, and he was less active. He died in Basel , french: link=no, Bâlois(e), it, Basilese , neighboring_munic ...
