Verticordia Elizabethiae
''Verticordia elizabethiae'', named as Elizabeth's featherflower, is a flowering plant in the myrtle family, Myrtaceae. An endemic species of Southwest Australia, it occurs near salt lakes as an erect bushy shrub. Taxonomy A species of ''Verticordia'', the featherflowers, assigned to a section of the genus ''Verticordia'' sect. ''Verticordella''. The type was collected in 2018 at a location reported imprecisely as Baladjie. Previously collected specimens, including one made by Charles Gardner in 1926 and another recognised as ''Verticordia'' sp. ''Koolyanobbing'', were assigned by the authors, Barbara Rye and Matthew Barrett, to the new species. The specific epithet honours the extensive contribution of Elizabeth Anne (Berndt) George, née Sykes (1935-2012) to the collection and research of verticordias. A treatment of the population had previously been published by George as an inland variant of ''Verticordia halophila''. Description A low growing salt tolerant shrub betwe ...

Barbara Rye
Barbara Lynette Rye is an Australian botanist born in 1952. Barbara Rye has been associated with the Western Australian Herbarium, where her work as a taxonomist has been the source of many new descriptions of plants. The number of taxa recorded as described by women authors is historically very low, of the terrestrial plant species this amount is around three percent, yet in analysis published in 2019 Rye is amongst the ten most prolific women taxonomists. Born in Perth, Western Australia, she spent her childhood investigating the local flora and fauna of the Southwest Australia region, a biodiversity hotspot, and later began studies at the University of Western Australia. Barbara Rye entered the fields of zoology and botany, taking a special interest in genetics and evolutionary biology. The first description of a new species was a ''Darwinia'', a genus of the family Myrtaceae that Rye investigated for her doctoral thesis, separating ''Darwinia capitellata ''Darwinia cap ...

Coolgardie Bioregion
Coolgardie is an Australian bioregion consisting of an area of low hills and plains of infertile sandy soil in Western Australia. It has an area of . It includes much of the Great Western Woodlands. Location and description This is a transition zone between the Mediterranean climate of Australia's south-west coast and the country's dry interior. The poor soil makes it unsuitable for agriculture but Coolgardie has been a gold and nickel mining area. It is bounded on the north by the arid Murchison bioregion, characterised by open Mulga woodlands and steppe. The low shrublands of the arid Nullarbor Plain lie to the east. The Mallee bioregion adjoins Coolgardie on the south. The Avon Wheatbelt bioregion is to the west. The Coolgardie bioregion, together with the coastal Hampton bioregion to the southeast, constitute the Coolgardie woodlands ecoregion defined by the World Wildlife Fund. Flora and fauna The low hills are home to woodland of endemic species of eucal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Flora Of Western Australia
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Halophytes
A halophyte is a salt-tolerant plant that grows in soil or waters of high salinity, coming into contact with saline water through its roots or by salt spray, such as in saline semi-deserts, mangrove swamps, marshes and sloughs and seashores. The word derives from Ancient Greek ἅλας (halas) 'salt' and φυτόν (phyton) 'plant'. Halophytes have different anatomy, physiology and biochemistry than glycophytes.Physiology of halophytes, T. J. FLOWERS, Plant and Soil 89, 41-56 (1985) An example of a halophyte is the salt marsh grass ''Spartina alterniflora'' (smooth cordgrass). Relatively few plant species are halophytes—perhaps only 2% of all plant species. Information about many of the earth's halophytes can be found in thehalophdatabase. The large majority of plant species are glycophytes, which are not salt-tolerant and are damaged fairly easily by high salinity. Classification Halophytes can be classified in many ways. According to Stocker (1933), it is mainly of 3 kind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Callitris
''Callitris'' is a genus of coniferous trees in the Cupressaceae (cypress family). There are 16 recognized species in the genus, of which 13 are native to Australia and the other three (''C. neocaledonica, C. sulcata'' and ''C. pancheri'') native to New Caledonia. Traditionally, the most widely used common name is cypress-pine, a name shared by some species of the closely related genus '' Actinostrobus''.Eckenwalder, J.E. 2009. ''Conifers of the World: The Complete Reference''. Timber Press. p. 122-124 Description They are small to medium-sized trees or large shrubs, reaching tall (to in ''C. macleayana''). The leaves are evergreen and scale-like. But young seedlings have needle-like leaves; in ''C. macleayana'', needle-like leaves are found mixed with scale leaves throughout the tree's life. The scales are arranged in six rows along the twigs, in alternating whorls of three (often in whorls of four in ''C. macleayana''). The male cones are small ...

Frankenia
''Frankenia'' (sea heath) is the only genus in the Frankeniaceae family of flowering plants. Other genera have been recognized within the family, such as ''Anthobryum'', ''Hypericopsis'' and ''Niederleinia'', but molecular phylogenetic studies have consistently shown that they all belong inside ''Frankenia''. ''Frankenia'' comprises about 70–80 species of shrubs, subshrubs and herbaceous plants, adapted to saline and dry environments throughout temperate and subtropical regions. A few species are in cultivation as ornamental plants. Description ''Frankenia'' species are salt tolerant ( halophytic) or drought tolerant ( xerophytic) shrubs, subshrubs or herbaceous plants. They have opposite, simple leaves, generally small and somewhat heather-like, and often with salt-excreting glands in sunken pits. Their flowers are small, either solitary or borne in various kinds of cyme. Each flower has four to seven sepals, joined at the base into a tube, and four to seven overlappi ...

Gunniopsis
''Gunniopsis'' is a genus of flowering plants in the iceplant family, Aizoaceae. These plants are found in areas of inland Australia. ''Gunniopis'' comprises 14 species that were once members of the genera ''Aizoon'', ''Gunnia'' and ''Neogunnia''. The name of the genus honours the botanist and politician Ronald Campbell Gunn. The genus was first formally described by the botanist Ferdinand Pax in 1889 in Engler and Prantl's work '' Die Naturlichen Pflanzenfamilien''. The name is derived from the Greek word ''opsis'' meaning resembling which alludes to the resemblance of the genus to the genus '' Gunnia''. Members of this genus are succulents with the habit of a small shrub or herb. The plants are widespread throughout the eremaean zones of Western Australia and South Australia with some species extending into the areas in the Northern Territory, Queensland and New South Wales. Found in arid areas the plants are often found in shrubland area with saline soils in and around sal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maireana
''Maireana '' is a genus of around 57 species of perennial shrubs and herbs in the family Amaranthaceae which are endemic to Australia. Species in this genus were formerly classified within the genus ''Kochia''. The genus was described in 1840 by the botanist, Moquin-Tandon and named to honour Joseph François Maire (1780-1867), an amateur botanist who befriended him during the author's first visit to Paris in 1834.Fournier, Eugene, Rapport sur l'herbier de M. le Docteur E. Cosson. (1867/ref>Moquin-Tandon, Alfred. Marcel Rolland(editor.) Un naturaliste à Paris sous Louis-Philippe: journal de voyage inédit (1834) 1944. The type species is '' Maireana tomentosa''.

Southern Cross, Western Australia
Southern Cross is a town in Western Australia, 371 kilometres east of state capital Perth on the Great Eastern Highway. It was founded by gold prospectors in 1888, and gazetted in 1890. It is the major town and administrative centre of the Shire of Yilgarn. At the , Southern Cross had a population of 680. The town of Southern Cross is one of the many towns that run along the Goldfields Water Supply Scheme pipeline from Mundaring to Kalgoorlie, engineered by C. Y. O'Connor, and as a consequence is an important location on the Golden Pipeline Heritage Trail. A succession of gold rushes in the Yilgarn region near Southern Cross in 1887, at Coolgardie in 1892, and at Kalgoorlie in 1893 caused a population explosion in the barren and dry desert centre of Western Australia. It is named after the Southern Cross constellation, and the town's streets are named after constellations and stars. The surrounding areas produce wheat and other cereal crops. The town is a receival site for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lignotuber
A lignotuber is a woody swelling of the root crown possessed by some plants as a protection against destruction of the plant stem, such as by fire. Other woody plants may develop basal burls as a similar survival strategy, often as a response to coppicing or other environmental stressors. However, lignotubers are specifically part of the normal course of development of the plants that possess them, and often develop early on in growth. The crown contains buds from which new stems may sprout, as well as stores of starch that can support a period of growth in the absence of photosynthesis. The term "lignotuber" was coined in 1924 by Australian botanist Leslie R. Kerr. Plants possessing lignotubers include many species in Australia: ''Eucalyptus marginata'' (Jarrah), ''Eucalyptus brevifolia'' (snappy gum) and ''Eucalyptus ficifolia'' (scarlet gum) all of which can have lignotubers wide and deep, as well as most mallees (where it is also known as a mallee root) and many ''Banksia ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
