Micromyrtus Chrysodema
''Micromyrtus chrysodema'' is a species of flowering plant in the myrtle family, Myrtaceae and is endemic to a small area of inland Western Australia. It is a densely branched shrub with small, narrowly oblong leaves and small white flowers. Description ''Micromyrtus chrysodema'' is a densely branched shrub with narrowly oblong to egg-shaped leaves with the narrower end towards the base, about long and wide on a petiole long, with four to eight glands on each side of the mid-vein. The flowers are about in diameter, and arranged in up to four upper leaf axils on a peduncle long with narrowly egg-shaped bracteoles about long at the base. The sepals are egg-shaped, about long and the petals are white, round to egg-shaped and about long. There are five stamens, the filaments about long. Taxonomy ''Micromyrtus chrysodema'' was first formally described in 2006 by Barbara Lynette Rye in the journal ''Nuytsia'' from specimens collected near Leinster in 2004. The specific epi ...

Barbara Lynette 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'' from a more widely ...

Endangered Flora Of Australia
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when ...

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 may have originated in the Aptian or Albian stages of the Cretaceous, between 125 and 99.6 million years ago. Today's broadleaved forests are dominated by rosid species, which in turn help with diversification in many other living lineages. Additionally, rosid herbs and shrubs are a significant part of arctic/alpine and temperate floras. The clade also includes some aquatic, desert and parasitic plants. 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 na ...

Endemic Flora Of Western Australia
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

Declared Rare And Priority Flora List
The Declared Rare and Priority Flora List is the system by which Western Australia's conservation flora are given a priority. Developed by the Government of Western Australia's Department of Environment and Conservation, it was used extensively within the department, including the Western Australian Herbarium The Western Australian Herbarium is the state Herbarium, situated in Perth, the capital of Western Australia. It houses a collection of more than 845,000 dried specimens of plants, algae, bryophytes (mosses, liverworts and hornworts), lichens, fu .... The herbarium's journal, '' Nuytsia'', which has published over a quarter of the state's conservation taxa, requires a conservation status to be included in all publications of new Western Australian taxa that appear to be rare or endangered. The system defines six levels of priority taxa: ;X: Threatened (Declared Rare Flora) – Presumed Extinct Taxa: These are taxa that are thought to be extinct, either because they have n ...

Triodia (plant)
''Triodia'' is a large genus of hummock grass endemic to Australia. The species of this genus are known by the common name spinifex, although they are not a part of the coastal genus '' Spinifex''. Many soft-leaved ''Triodia'' species were formerly included in the genus ''Plectrachne''. ''Triodia'' is known as ''tjanpi'' (grass) in central Australia, and have several traditional uses amongst the Aboriginal Australian peoples of the region. A multiaccess key (SpiKey) is available as a free application for identifying the ''Triodia'' of the Pilbara (28 species and one hybrid). Description ''Triodia'' species are perennial Australian hummock grasses that grow in arid regions. Their leaves (30–40 centimetres long) are subulate ( awl-shaped, with a tapering point). The leaf tips, which are high in silica, can break off in the skin, leading to infections. Uses Spinifex has had many traditional uses for Aboriginal Australians. Several species were (and are) used extensively ...
