Pimelea Macrostegia
''Pimelea macrostegia'' is a species of flowering plant in the family Thymelaeaceae and is endemic to Kangaroo Island in South Australia. It is a shrub with glabrous, narrowly elliptic leaves and clusters of pale yellow flowers surrounded by 4 or 6 egg-shaped, pale green involucral bracts. Description ''Pimelea macrostegia'' is a shrub that typically grows to a height of and has glabrous stems. Its leaves are narrowly elliptic, long and wide on a short petiole. The flowers are pale yellow and arranged in clusters of 50 to 90 on a peduncle long. There are 4 or 6 pale green, sometimes also purplish, egg-shaped or broadly egg-shaped involucral bracts, mostly long and wide around the flower clusters, each flower on a hairy pedicel. The sepals are long, the floral tube long, and the stamens longer than the sepals. Flowering occurs from November to February. Taxonomy This pimelea was first formally described in 1873 by George Bentham, who gave it the name ''Pimelea li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Benth
George Bentham (22 September 1800 – 10 September 1884) was an English botanist, described by the weed botanist Duane Isely as "the premier systematic botanist of the nineteenth century". Born into a distinguished family, he initially studied law, but had a fascination with botany from an early age, which he soon pursued, becoming president of the Linnaean Society in 1861, and a fellow of the Royal Society in 1862. He was the author of a number of important botanical works, particularly flora. He is best known for his taxonomic classification of plants in collaboration with Joseph Dalton Hooker, his ''Genera Plantarum'' (1862–1883). He died in London in 1884.

Taxa Named By George Bentham
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in '' Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malvales Of Australia
The Malvales are an order of flowering plants. As circumscribed by APG II-system, the order includes about 6000 species within 9 families. The order is placed in the eurosids II, which are part of the eudicots. The plants are mostly shrubs and trees; most of its families have a cosmopolitan distribution in the tropics and subtropics, with limited expansion into temperate regions. An interesting distribution occurs in Madagascar, where three endemic families of Malvales (Sphaerosepalaceae, Sarcolaenaceae and Diegodendraceae) occur. Many species of Malvaceae ''sensu lato'' are known for their wood, with that of ''Ochroma'' (balsa) being known for its lightness, and that of ''Tilia'' (lime, linden, or basswood) as a popular wood for carving. Fruit of the cacao tree (''Theobroma cacao'') are used as an ingredient for chocolate. Kola nuts (genus ''Cola'') are notable for their high content of caffeine and, in past, were commonly used for preparing of various cola drinks. Other well-k ...

Pimelea
''Pimelea'', commonly known as rice flowers, is a genus of plants belonging to the family Thymelaeaceae. There are about 150 species, including 110 in Australia and thirty six in New Zealand. Description Plants in the genus ''Pimelea'' are herbs or small shrubs usually with leaves arranged in opposite pairs. The leaves are usually paler on the lower surface and the petiole is usually very short. The flowers are usually arranged in groups on the ends of the branches and have no petals but four petal-like sepals and two stamens. The ovary has a single ovule and the fruit is usually a nut containing a single seed. Taxonomy and naming The genus ''Pimelea'' was first formally described in 1788 by Joseph Gaertner from unpublished descriptions by Joseph Banks and Daniel Solander. The first species Gaertner described was ''Pimelea laevigata'', now known as ''Pimelea prostrata''. The name ''Pimelea'' is from the Ancient Greek word ''pimele'' meaning "fat or "lard", possibly referring ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transactions And Proceedings Of The Royal Society Of South Australia
The Royal Society of South Australia (RSSA) is a learned society whose interest is in science, particularly, but not only, of South Australia. The major aim of the society is the promotion and diffusion of scientific knowledge, particularly in relation to natural sciences. The society was originally the Adelaide Philosophical Society, founded on 10 January 1853. The title "Royal" was granted by Queen Victoria in October 1880 and the society changed its name to its present name at this time. It was incorporated in 1883. It also operates under the banner Science South Australia. History The origins of the Royal Society are related to the South Australian Literary and Scientific Association, founded in August 1834, before the colonisation of South Australia, and whose book collection eventually formed the kernel of the State Library of South Australia. The Society had its origins in a meeting at the Stephens Place home of J. L. Young (founder of the Adelaide Educational Institutio ...

John McConnell Black
John McConnell Black (28 April 1855 – 2 December 1951) was a Scottish botanist who emigrated to Australia in 1877 and eventually documented and illustrated thousands of flora in South Australia in the early 20th century. His publications assisted many botanists and scientists in the decades that followed. He was the younger brother of theatre and hotel manager Helen Carte. Black was born at Wigtown, Scotland and educated at Wigtown Grammar School, the Edinburgh Academy, the College School, Taunton and a commercial trade school in Dresden, Germany. He was a linguist, able to understand Arabic, French, German, Italian, Russian and Spanish. He migrated to Australia in 1877 and developed an interest in Australian Aboriginal languages. In 1879 Black married Alice Denford and they had a daughter and three sons. He began working as a journalist in 1883. After a tour of South America and Europe following his mother's death in 1903, Black focused on systematic botany. In 1909 he p ...

Frederick George Waterhouse
Frederick George Waterhouse (25 August 1815 – 7 September 1898) was an English naturalist, zoologist and entomologist who made significant contributions to the study of the natural history of Australia. Waterhouse was born near London, a son of solicitor J. W. Waterhouse. He was a keen naturalist and worked with his elder brother George Robert Waterhouse at the Natural History Museum, London, British Museum (Natural History). On 7 July 1852 he married Fanny Shepherd Abbott (c. 1831 – 7 August 1875), and soon after they sailed for South Australia in the ''Sydney'', the first steamer to make the voyage. Together they had five sons and one daughter. His original intention was to prospect for gold at the Victorian diggings, but he was unsuccessful and found employment with C. T. Hargrave, surveying in the Mount Lofty Ranges and Kangaroo Island. In 1860 he became curator of the South Australian Museum, South Australian Institute Museum, which opened in 1862, and which he had hel ...

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.

Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''sporangium, microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...

Thymelaeaceae
The Thymelaeaceae are a cosmopolitan family of flowering plants composed of 50 genera (listed below) and 898 species.Zachary S. Rogers (2009 onwards)A World Checklist of Thymelaeaceae (version 1) Missouri Botanical Garden Website, St. Louis. It was established in 1789 by Antoine Laurent de Jussieu.Antoine Laurent de Jussieu ''Genera Plantarum'', page 76. Herrisant & Barrois, Paris. The Thymelaeaceae are mostly trees and shrubs, with a few vines and herbaceous plants. Description This is not intended as a full botanical description, but only as a few notes on some of the conspicuous or unusual traits of the family when ''Tepuianthus'' is excluded. The bark is usually shiny and fibrous. Attempts to break the stem often result in a strip of bark peeling down the side.Ernst Schmidt, Mervyn Lotter and Warren McCleland The number of stamens is usually once or twice the number of calyx lobes. If twice, then they often occur in two well separated series. Exceptions include ''Gonystylu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
