Thomasia Macrocalyx
''Thomasia macrocalyx'' is a species of flowering plant in the family Malvaceae and is endemic to the south-west of Western Australia. It is an erect, bushy shrub with densely hairy new growth, egg-shaped leaves with a heart-shaped base and lobed or toothed edges, and groups of pale purple to mauve or white flowers. Description ''Thomasia macrocalyx'' is an erect, bushy shrub that typically grows to a height of , its young growth densely covered with pale or brownish, star-shaped hairs. The leaves are egg-shaped with a heart-shaped base, long and wide on a petiole long. The edges of the leaves are toothed or lobed, both surfaces densly covered with star-shaped hairs, the upper surface becoming glabrous with age. The flowers are arranged in hairy racemes of 2 to 6, long with egg-shaped bracteoles long at the base, the flowers in diameter. The sepals are joined at the base and covered with both simple and star-shaped hairs. Flowering occurs from May to December. Taxonomy a ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rosids Of Western Australia
The rosids are members of a large clade (monophyletic group) of flowering plants, containing about 70,000 species, more than a quarter of all angiosperms. The clade is divided into 16 to 20 orders, depending upon circumscription and classification. These orders, in turn, together comprise about 140 families. Fossil rosids are known from the Cretaceous period. Molecular clock estimates indicate that the rosids originated in the Aptian or Albian stages of the Cretaceous, between 125 and 99.6 million years ago. Today's forests are highly dominated by rosid species, which in turn helped with diversification in many other living lineages. Additionally, rosid herbs and shrubs are also a significant part of arctic/alpine, temperate floras, aquatics, desert plants, and parasites. Name The name is based upon the name "Rosidae", which had usually been understood to be a subclass. In 1967, Armen Takhtajan showed that the correct basis for the name "Rosidae" is a description of a gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomasia
''Thomasia'' is a genus of thirty-one species of flowering plants in the family Malvaceae. Plants in this genus are small shrubs that are endemic to the south-west of Western Australia, apart from '' T. petalocalyx'' that is native to Victoria and South Australia. The leaves are simple with leaf-like stipules at the base of the petiole, the flowers bisexual with five papery, petal-like sepals, usually five petals and five stamens opposite the petals. The fruit is a capsule covered with star-like hairs. Taxonomy The genus ''Thomasia'' was first formally described in 1821 by Jaques Étienne Gay in ''Mémoires du Muséum d'Histoire Naturelle''. The name ''Thomasia'' honours Pierre Thomas, his son Abraham, and Abraham's sons Philippe, Louis and Emmanuel, a family of Swiss plant collectors. Species list The following is a listed of ''Thomasia'' species recognised by the Australian Plant Census as at December 2020: *'' Thomasia angustifolia'' Steud. - narrow-leaved thomasia *'' T ...

Department Of Biodiversity, Conservation And Attractions (Western Australia)
The Department of Biodiversity, Conservation and Attractions (DBCA) is the Western Australian government department responsible for managing lands and waters described in the ''Conservation and Land Management Act 1984'', the ''Rottnest Island Authority Act 1987'', the ''Swan and Canning Rivers Management Act 2006'', the ''Botanic Gardens and Parks Authority Act 1998'', and the ''Zoological Parks Authority Act 2001'', and implementing the state's conservation and environment legislation and regulations. The Department reports to the Minister for Environment and the Minister for Tourism. DBCA was formed on 1 July 2017 by the merger of the Department of Parks and Wildlife (DPaW), the Botanic Gardens and Parks Authority, the Zoological Parks Authority and the Rottnest Island Authority. The former DPaW became the Parks and Wildlife Service.

Mallee Bioregion
Mallee, also known as Roe Botanical District, is a biogeographic region in southern Western Australia. Located between the Esperance Plains, Avon Wheatbelt and Coolgardie bioregions, it has a low, gently undulating topography, a semi-arid mediterranean climate, and extensive ''Eucalyptus'' mallee vegetation. It has an area of . About half of the region has been cleared for intensive agriculture. Recognised as a region under the Interim Biogeographic Regionalisation for Australia (IBRA), it was first defined by John Stanley Beard in 1980. Geography and geology The Mallee region has a complex shape with tortuous boundaries, but may be roughly approximated as the triangular area south of a line from Bruce Rock to Eyre, but not within 40 kilometres (25 mi) of the south coast, except at its eastern limits. It has an area of about 79000 square kilometres (31000 mi²), making it about a quarter of the South West Botanic Province, 3% of the state, and 1% of Australia. It ...

Avon Wheatbelt
The Avon Wheatbelt is a bioregion in Western Australia. It has an area of . It is considered part of the larger Southwest Australia savanna ecoregion. Geography The Avon Wheatbelt bioregion is mostly a gently undulating landscape with low relief. It lies on the Yilgarn Craton, an ancient block of crystalline rock, which was uplifted in the Tertiary and dissected by rivers. The craton is overlain by laterite deposits, which in places have decomposed into yellow sandplains, particularly on low hills. Steep-sided erosional gullies, known as breakaways, are common.

Darling Range
The Darling Scarp, also referred to as the Darling Range or Darling Ranges, is a low escarpment running north–south to the east of the Swan Coastal Plain and Perth, Western Australia. The escarpment extends generally north of Bindoon, to the south of Pemberton. The adjacent Darling Plateau goes easterly to include Mount Bakewell near York and Mount Saddleback near Boddington. It was named after the Governor of New South Wales, Lieutenant-General Ralph Darling. History The feature was first recorded as General Darling Range by Charles Fraser, Government Botanist with Captain James Stirling aboard in March 1827. Maps from the 1830s show the scarp labelled " General Darlings Range"; this later became Darling Range, a name by which the formation was still commonly known in the late 20th century despite common understanding of it being an escarpment. There is also a tendency to identify the locations on or to the east of the scarp as being in the "Perth Hills" (or simpl ...
