Banksia Splendida
''Banksia splendida'', commonly known as shaggy dryandra, is a species of shrub that is endemic to the southwest of Western Australia. It has sharply-pointed linear leaves that are woolly on the lower surface, cream-coloured and maroon or yellow flowers in heads of between 65 and 115, and later up to eight egg-shaped follicles in each head. Description ''Banksia splendida'' is a much-branched shrub that typically grows to a height of but does not form a lignotuber. It has sharply-pointed, linear leaves that are long and wide on a petiole long. The edges of the leaves are rolled under and the lower surface in woolly-hairy. The flowers are arranged in a head of between 65 and 115 with linear, tapering and thread-like involucral bracts long at the base of the head. The perianth is cream-coloured near its base, maroon or yellow above, long and the pistil is cream-coloured, long with a pale red pollen-presenter. Flowering occurs from July to September and the fruit is an e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tathra National Park
Tathra National Park is a national park in Western Australia, located north of Perth between the towns of Eneabba and Carnamah on Winchester-Eneabba Road. The name is derived from a Noongar word meaning "beautiful place". Description The park is set in sandplain country and is surrounded by farmland, having escaped clearing by wheat farmers in the early 20th century. Shallow valleys with sandy floors change to laterite on the slopes and hilltops, and the low heath changes in composition accordingly. The park is considered a representative sample of flora of the area, although includes some unusual plants - including a species of ''Daviesia'' notable for its large red flowers, which is known only from the reserve, and shaggy dryandra ('' Banksia splendida''), which is common on some lateritic rises. Public usage of the park was mainly for wildflower observation in winter and spring according to a 1974 report, whose recommendation (which was not followed) would have seen it de ...

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjug ...

DNA Sequence
DNA sequencing is the process of determining the nucleic acid sequence – the order of nucleotides in DNA. It includes any method or technology that is used to determine the order of the four bases: adenine, guanine, cytosine, and thymine. The advent of rapid DNA sequencing methods has greatly accelerated biological and medical research and discovery. Knowledge of DNA sequences has become indispensable for basic biological research, DNA Genographic Projects and in numerous applied fields such as medical diagnosis, biotechnology, forensic biology, virology and biological systematics. Comparing healthy and mutated DNA sequences can diagnose different diseases including various cancers, characterize antibody repertoire, and can be used to guide patient treatment. Having a quick way to sequence DNA allows for faster and more individualized medical care to be administered, and for more organisms to be identified and cataloged. The rapid speed of sequencing attained with modern D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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] |
Autonym (botany)
In botanical nomenclature, autonyms are automatically created names, as regulated by the '' International Code of Nomenclature for algae, fungi, and plants'' that are created for certain subdivisions of genera and species, those that include the type of the genus or species. An autonym might not be mentioned in the publication that creates it as a side-effect. Autonyms "repeat unaltered" the genus name or species epithet of the taxon being subdivided, and no other name for that same subdivision is validly published (article 22.2). For example, ''Rubus'' subgenus ''Eubatus'' is not validly published, and the subgenus is known as ''Rubus'' subgen. ''Rubus''. Autonyms are cited without an author. The publication date of the autonym is taken to be the same as that of the subdivision(s) that automatically established the autonym, with some special provisions (the autonym is considered to have priority over the other names of the same rank established at the same time (article 11.6)). ...

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 ''Nuytsia floribunda'' is a hemiparasitic tree found in Western Australia. The species is known locally as moodjar and, more recently, the Christmas tree or Western Australian Christmas tree.

Alex George (botanist)
Alexander Segger George (born 4 April 1939) is a Western Australian botanist. He is the authority on the plant genera ''Banksia'' and ''Dryandra''. The "bizarre" Restionaceae genus '' Alexgeorgea'' was named in his honour in 1976. Early life Alex Segger George was born in Western Australia on 4 April 1939. Career George joined the Western Australian Herbarium as a laboratory assistant at the age of twenty in 1959. He worked under Charles Gardner for a year before the latter's retirement, and partly credits him with rekindling an interest in banksias. In 1963 he graduated with a Bachelor of Arts from the University of Western Australia, and the following year added a botany major. Continuing at the Western Australian Herbarium as a botanist, in 1968 he was seconded as Australian Botanical Liaison Officer at the Royal Botanic Gardens in London. George also has an interest in history, especially historical biography of naturalists in Western Australia. He has published a numbe ...

Flora Australiensis
''Flora Australiensis: a description of the plants of the Australian Territory'', more commonly referred to as ''Flora Australiensis'', and also known by its standard abbreviation ''Fl. Austral.'', is a seven-volume flora of Australia published between 1863 and 1878 by George Bentham, with the assistance of Ferdinand von Mueller. It was one of the famous Kew series of colonial floras, and the first flora of any large continental area that had ever been finished. In total the flora included descriptions of 8125 species.Orchard, A. E. 1999. Introduction. In A. E. Orchard, ed. ''Flora of Australia - Volume 1'', 2nd edition pp 1-9. Australian Biological Resources Study Bentham prepared the flora from Kew; with Mueller, the first plant taxonomist residing permanently in Australia, loaning the entire collection of the National Herbarium of Victoria to Bentham over the course of several years.

Bentham's Taxonomic Arrangement Of Dryandra
George Bentham's taxonomic arrangement of ''Dryandra'' (now ''B.'' ser. ''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. Background The dryandras are a group of proteaceous shrubs endemic to southwest Western Australia. For nearly two hundred years they were considered a separate genus, having been published at that rank in 1810 by Robert Brown. In 2007 it was transferred into the genus ''Banksia'' as ''B.'' ser. ''Dryandra''. There are now just under 100 species, plus numerous subspecies and varieties. The first infrageneric arrangement of ''Dryandra'' was Brown's 1810 arrangement, which listed 13 species, but did not attempt an infrageneric classification. Twenty years later, Brown published a revised arrangement which divided 23 recognised species in three subgenera, and placed one ...
