Dryandra Subg. Hemiclidia
''Dryandra'' subg. ''Hemiclidia'' is an obsolete plant taxon that encompassed material that is now included in '' Banksia''. Published at genus rank as ''Hemiclidia'' by Robert Brown in 1830, it was set aside by George Bentham in 1870, but reinstated at subgenus rank by Alex George in 1996. In 2007, all ''Dryandra'' species were transferred into ''Banksia'' at series rank, and the infrageneric ''Dryandra'' taxa, including ''D.'' subg. ''Hemiclidia'', were set aside. According to Brown In 1810, Robert Brown published the genus ''Dryandra'' in his ''On the Proteaceae of Jussieu''. Thirteen species were published, including ''Dryandra falcata'' (now '' Banksia falcata''), but no infrageneric arrangement was proffered. Twenty years later, Brown published a further eleven species and the first infrageneric arrangement in his ''Supplementum primum prodromi florae Novae Hollandiae''. By this time, Brown had observed the tendency in ''D. falcata'' for one of the two ovules i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prodromus Systematis Naturalis Regni Vegetabilis
''Prodromus Systematis Naturalis Regni Vegetabilis'' (1824–1873), also known by its standard botanical abbreviation ''Prodr. (DC.)'', is a 17-volume treatise on botany initiated by Augustin Pyramus de Candolle. De Candolle intended it as a summary of all known seed plants, encompassing taxonomy, ecology, evolution and biogeography. He authored seven volumes between 1824 and 1839, but died in 1841. His son, Alphonse de Candolle, then took up the work, editing a further ten volumes, with contributions from a range of authors. Volume 17 was published in October 1873. The fourth and final part of the index came out in 1874. The ''Prodromus'' remained incomplete, dealing only with dicotyledons. In the ''Prodromus'', De Candolle further developed his concept of families. Note that this system was published well before there were internationally accepted rules for botanical nomenclature. Here, a family is indicated as "ordo". Terminations for families were not what they are now. Neith ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Historically Recognized Angiosperm Taxa
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of the p ...

Series (botany)
In botany and plant taxonomy, a series is a subdivision of a genus, a taxonomic rank below that of section (and subsection) but above that of species. Sections and/or series are typically used to help organize very large genera, which may have hundreds of species. Cultivar marketing The term "series" is also used (in seed marketing) for groupings of cultivars, but this term has no formal status with that meaning in the ''ICNCP The ''International Code of Nomenclature for Cultivated Plants'' (ICNCP), is a guide to the rules and regulations for naming cultigens, plants whose origin or selection is primarily due to intentional human activity.

Austin Mast
Austin R. Mast is a research botanist. Born in 1972, he obtained a Ph.D. from the University of Wisconsin–Madison in 2000. He is currently a professor within the Department of Biological Science at Florida State University (FSU), and has been director of FSU's Robert K. Godfrey Herbarium since August 2003. One of his main areas of research is the phylogenetics of Grevilleoideae, a subfamily of Proteaceae. In 2005 he showed the genus ''Banksia'' to be paraphyletic with respect to ''Dryandra'', Collaborating with Australian botanist Kevin Thiele, he subsequently transferred all ''Dryandra'' taxa to ''Banksia'', publishing over 120 taxonomic names in the process. The change has been adopted by the Western Australian Herbarium, although has met with some controversy. He has previously worked on the Deep South Plant Specimen Imaging Project, which created a repository of annotated high-resolution digital images of plant specimens within the East Gulf Coastal Plain The Gulf Coastal ...

Dryandra Subg
''Banksia'' ser. ''Dryandra'' is a series of 94 species of shrub to small tree in the plant genus ''Banksia''. It was considered a separate genus named ''Dryandra'' until early 2007, when it was merged into ''Banksia'' on the basis of extensive molecular and morphological evidence that ''Banksia'' was paraphyletic with respect to ''Dryandra''. Taxonomy The dryandras were named in honour of Swedish botanist Jonas C. Dryander. The first specimens of a ''Dryandra'' were collected by Archibald Menzies, surgeon and naturalist to the Vancouver Expedition. At the request of Joseph Banks, Menzies collected natural history specimens wherever possible during the voyage. During September and October 1791, while the expedition were anchored at King George Sound, he collected numerous plant specimens, including the first specimens of '' B. sessilis'' (Parrotbush) and '' B. pellaeifolia''. Upon Menzies' return to England, he turned his specimens over to Banks; as with most other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banksia Ser
''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 endangered. ...

George's Taxonomic Arrangement Of Dryandra
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. Background The dryandras are a group of 94 species in the plant family Proteaceae. Endemic to south-west Western Australia, they grow in forms varying from prostrate shrubs to small trees. ''Dryandra'' was originally published at genus rank in 1810, and was still considered a genus in the 1990s when George published his infra ...

Nuytsia (journal)
''Nuytsia'' is a peer-reviewed scientific journal published by the Western Australian Herbarium. It publishes papers on systematic botany, giving preference to papers related to the flora of Western Australia. Nearly twenty percent of Western Australia's plant taxa have been published in ''Nuytsia''. The journal was established in 1970 and has appeared irregularly since. The editor-in-chief is Kevin Thiele. ''Nuytsia'' is named after the monospecific genus ''Nuytsia'', whose only species is '' Nuytsia floribunda'', the Western Australian Christmas tree. Occasionally, the journal has published special issues, such as an issue in 2007 substantially expanding described species from Western Australia. Publication details The record of the issues published is found at the ''FloraBase ''FloraBase'' is a public access web-based database of the flora of Western Australia. It provides authoritative scientific information on 12,978 taxa, including descriptions, maps, images, conservati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Banksia Glaucifolia
''Banksia glaucifolia'' is a species of shrub that is endemic to Western Australia. It has deeply serrated, wedge-shaped leaves with sharply pointed lobes, pale yellow flowers and follicles with hairy edges. Description ''Banksia glaucofolia'' is a shrub that typically grows to a height of and has hairy stems but does not form a lignotuber. Its leaves are wedge-shaped in outline, deeply serrated, long and wide on a flat, hairy petiole long. The leaves are more or less glaucous and have between six and thirteen narrow triangular, sharply pointed lobes on each side. The flowers are borne on a head containing between 80 and 110 flowers in each head. There are broadly linear involucral bracts long at the base of the head. The flowers have a pale yellow perianth long and a cream-coloured pistil long. Flowering occurs from July to October and the follicles are egg-shaped, about long and hairy along the edges.
