Sprengelia Distichophylla
''Sprengelia distichophylla'' is a species of flowering plant in the heath family Ericaceae and is endemic to Tasmania. It is a tufted shrub that typically grows to a height of with leaves about long, arranged in two closely overlapping rows, with the bases sheathing the stem. The flowers are arranged singly in leaf axils and are white, about long and bell-shaped. Flowering occurs in summer. This species was first formally described in 1903 by Leonard Rodway who gave it the name ''Sprengelia incarnata'' var. ''distichophylla'' in ''The Tasmanian Flora''. In 1963, Winifred Curtis raised the variety to species status as ''Sprengelia distichophylla'' in ''The Student's Flora of Tasmania''. The specific epithet 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, bot ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Ericaceae
The Ericaceae are a family of flowering plants, commonly known as the heath or heather family, found most commonly in acidic and infertile growing conditions. The family is large, with c.4250 known species spread across 124 genera, making it the 14th most species-rich family of flowering plants. The many well known and economically important members of the Ericaceae include the cranberry, blueberry, huckleberry, rhododendron (including azaleas), and various common heaths and heathers (''Erica'', ''Cassiope'', ''Daboecia'', and ''Calluna'' for example). Description The Ericaceae contain a morphologically diverse range of taxa, including herbs, dwarf shrubs, shrubs, and trees. Their leaves are usually evergreen, alternate or whorled, simple and without stipules. Their flowers are hermaphrodite and show considerable variability. The petals are often fused (sympetalous) with shapes ranging from narrowly tubular to funnelform or widely urn-shaped. The corollas are usually ra ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Leonard Rodway
Leonard Rodway (5 October 1853 – 9 March 1936) was an English-born Australian dentist and botanist. Early life Rodway was born in Torquay Devon, England, the thirteenth child of Henry Barron Rodway, a dentist and inventor of the Rodway life buoy, and his wife Elizabeth, ''née'' Allin. Leonard Rodway was educated in Birmingham and aboard the Thames Nautical Training College ship, ''Worcester'', obtaining double first-class certificates. He served for three years as a midshipman in the merchant service, but decided to follow his father into dentistry. He obtained the licentiateship of the Royal College of Surgeons, London in 1878.Elias, A. (1988). Rodway, Leonard (1853–1936). ''Australian Dictionary of Biography'', Vol. 11 MUP, p 436-437, 1988. Career Rodway emigrated to Australia and settled in Hobart, Tasmania. Rodway was registered under the first Tasmanian Dental Act 1884, but is mainly remembered for his interest in botany. In 1896 he was appointed honorary go ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winifred Curtis
Winifred Mary Curtis (15 June 1905 – 14 October 2005) was a United Kingdom, British-born Australian botanist, author and a pioneer researcher in plant embryology and cell (biology), cytology who played a prominent role in the department of botany at the University of Tasmania (UTAS), where the main plant science laboratory is named in her honour. Biography Curtis was born on 15 June 1905 in London, the only child of Herbert John Curtis and Elizabeth Winifred Curtis (née Baker). Curtis lived in India for several years as a child after her father was posted there. She was a gifted student, and studied science at University College, London from 1924, winning various awards and scholarships. She graduated in 1927 and completed an honours degree in Botany the following year for research on ''Spartinia townsendii'', and ''Taraxacum'' (dandelions). This was followed by several years of travel through Europe and teaching in Manchester and Hampstead. In 1939 she emigrated to Australi ...

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] |
Epacridoideae
Epacridoideae is a subfamily of the family Ericaceae. The name Styphelioideae Sweet is also used. The subfamily contains around 35 genera and 545 species. Many species are found in Australasia, others occurring northwards through the Pacific to Southeast Asia, with a small number in South America. Description The Epacridoideae form a well supported monophyletic group within the family Ericaceae, clearly diagnosable using a combination of morphological characters. These include a lignified leaf epidermis, dry, membrane-like (scarious) bracts on the inflorescence, and a persistent corolla. The stamens are also distinctive: there are fewer than twice the number of corolla lobes and their filaments are smooth. Some of these characters are individually present in other members of the family Ericaceae. Core members of the subfamily (i.e. excluding Prionoteae) also have parallel- or somewhat palmate-veined leaves and lack multicellular hairs. Taxonomy In 1810, Robert Brown treated the ...

Sprengelia
''Sprengelia'' is a genus of flowering plants in the family Ericaceae and is endemic to eastern Australia. Plants in the genus ''Sprengelia'' are slender, erect or low-lying shrubs with overlapping, stem-clasping leaves, many bracts at the base of the flowers, the sepals egg-shaped, white or coloured, the five petals with spreading lobes, and the fruit a capsule. The genus ''Sprengelia'' was first formally described in 1794 by James Edward Smith in the journal ''Kongliga Vetenskaps Academiens Nya Handlingar'', later published in translation in ''Tracts relating to natural history''. The first species described was '' Sprengelia incarnata''. The genus name honours the German botanist Christian Konrad Sprengel. The names of seven species are accepted by the Australian Plant Census The Australian Plant Census (APC) provides an online interface to currently accepted, published, scientific names of the vascular flora of Australia, as one of the output interfaces of the national gove ...

Ericales Of Australia
The Ericales are a large and diverse order of dicotyledons. Species in this order have considerable commercial importance including for tea, persimmon, blueberry, kiwifruit, Brazil nuts, argan, and azalea. The order includes trees, bushes, lianas, and herbaceous plants. Together with ordinary autophytic plants, the Ericales include chlorophyll-deficient mycoheterotrophic plants (e.g., '' Sarcodes sanguinea'') and carnivorous plants (e.g., genus ''Sarracenia''). Many species have five petals, often grown together. Fusion of the petals as a trait was traditionally used to place the order in the subclass Sympetalae. Mycorrhizal associations are quite common among the order representatives, and three kinds of mycorrhiza are found exclusively among Ericales (namely, ericoid, arbutoid and monotropoid mycorrhiza). In addition, some families among the order are notable for their exceptional ability to accumulate aluminum. Ericales are a cosmopolitan order. Areas of distribution of fa ...

Flora Of Tasmania
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
