Melaleuca Similis
''Melaleuca similis'' is a plant in the myrtle family, Myrtaceae and is endemic to the south west of Western Australia. It is a small shrub, similar to '' Melaleuca stramentosa'' with its narrow, almost cylindrical leaves and heads of pink to purple flowers but lacks the matted, silky hairs on the young leaves and outer edge of the flower cup. Description ''Melaleuca similis'' is a shrub growing to tall with dense foliage. Its leaves are long, wide, linear to very narrow egg-shaped, roughly circular in cross section. The flowers are a shade of pink to purple and arranged in heads on the ends of branches which continue to grow after flowering and sometimes also in the upper leaf axils. Each head contains up to 4 groups of flowers in threes and is up to in diameter. The outer surface of the flower cup (the hypanthium) is hairy although it lacks the woolly, matted hairs of ''M. stramentosa''. The petals are long and fall off as the flower matures. There are five bundles of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lyndley Craven
Lyndley Alan Craven (3 September 1945 – 11 July 2014) was a botanist who became the Principal Research Scientist of the Australian National Herbarium. Lyndley ("Lyn") Craven worked for the CSIRO plant taxonomy unit of the New Guinea Survey Group, Division of Land Research and Regional Survey from 1964 to 1967. This was part of a unit that became the Australian National Herbarium, Centre for Australian National Biodiversity Research. Craven's duties included botanical support for land resources surveys. Craven then left to study horticulture at Burnley Horticultural College, Victoria, earning the degree of Diploma of Horticultural Science in 1970 before being briefly employed by the Parks and Gardens Branch of Department of the Interior, Canberra. Part of this department later became the Canberra Botanic Garden and eventually the Australian National Herbarium, Centre for Australian National Biodiversity Research at the Australian National Botanic Gardens.

Melaleuca Plumea
''Melaleuca plumea'' is a shrub in the myrtle family, Myrtaceae, and is endemic to the south of Western Australia. It is a widely spreading, densely foliaged shrub which produces masses of deep pink flowers in spring and early summer. Fluffy hairs on parts of the flowers, including the bracts covering the flower buds, are also a feature. Description ''Melaleuca plumea'' is a low, ground-hugging shrub growing to a height of and sometimes more than wide. The leaves are arranged alternately, long, wide, linear to narrow oval in shape, the end either round or with a short point. The flowers are a shade of pink or purple. They are arranged in heads near the ends of branches which continue to grow after flowering and also in some of the upper leaf axils. The flower buds are covered with brown bracts. The bracts, flower bases (hypanthia) and sepals are all covered with white fluff. Each head contains up to 5 groups of flowers in threes and is up to in diameter. The stamens, whic ...

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 group ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 1999
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ability ...

Myrtales Of Australia
The Myrtales are an order of flowering plants placed as a sister to the eurosids II clade as of the publishing of the ''Eucalyptus grandis'' genome in June 2014. The APG III system of classification for angiosperms still places it within the eurosids. This finding is corroborated by the placement of the Myrtales in the Malvid clade by the One Thousand Plant Transcriptomes Initiative. The following families are included as of APGIII: * Alzateaceae S. A. Graham * Combretaceae R. Br. ( leadwood family) * Crypteroniaceae A. DC. * Lythraceae J. St.-Hil. ( loosestrife and pomegranate family) * Melastomataceae Juss. (including Memecylaceae DC.) * Myrtaceae Juss. (myrtle family; including Heteropyxidaceae Engl. & Gilg, Psiloxylaceae Croizat) * Onagraceae Juss. (evening primrose and Fuchsia family) * Penaeaceae Sweet ex Guill. (including Oliniaceae Arn., Rhynchocalycaceae L. A. S. Johnson & B. G. Briggs) * Vochysiaceae A. St.-Hil. The Cronquist system gives essentially the same co ...

Melaleuca
''Melaleuca'' () is a genus of nearly 300 species of plants in the myrtle family, Myrtaceae, commonly known as paperbarks, honey-myrtles or tea-trees (although the last name is also applied to species of '' Leptospermum''). They range in size from small shrubs that rarely grow to more than high, to trees up to . Their flowers generally occur in groups, forming a "head" or "spike" resembling a brush used for cleaning bottles, containing up to 80 individual flowers. Melaleucas are an important food source for nectarivorous insects, birds, and mammals. Many are popular garden plants, either for their attractive flowers or as dense screens and a few have economic value for producing fencing and oils such as "tea tree" oil. Most melaleucas are endemic to Australia, with a few also occurring in Malesia. Seven are endemic to New Caledonia, and one is found only on (Australia's) Lord Howe Island. Melaleucas are found in a wide variety of habitats. Many are adapted for life in swamp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Government Of Western Australia
The Government of Western Australia, formally referred to as His Majesty's Government of Western Australia, is the Australian state democratic administrative authority of Western Australia. It is also commonly referred to as the WA Government or the Western Australian Government. The Government of Western Australia, a parliamentary constitutional monarchy, was formed in 1890 as prescribed in its Constitution, as amended from time to time. Since the Federation of Australia in 1901, Western Australia has been a state of the Commonwealth of Australia, and the Constitution of Australia regulates its relationship with the Commonwealth. Under the Australian Constitution, Western Australia ceded legislative and judicial supremacy to the Commonwealth, but retained powers in all matters not in conflict with the Commonwealth. History Executive and judicial powers Western Australia is governed according to the principles of the Westminster system, a form of parliamentary government ba ...

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 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 not been collected for over 50 years despite thorough searching, or because all known wild populations have been destroyed. They have been declared as such in accordance with the Wildlife Conservation Act 1950, and are therefore afforded legislative protecti ...

IBRA
The Interim Biogeographic Regionalisation for Australia (IBRA) is a biogeographic regionalisation of Australia developed by the Australian government's Department of Sustainability, Environment, Water, Population, and Communities. It was developed for use as a planning tool, for example for the establishment of a national reserve system. The first version of IBRA was developed in 1993–94 and published in 1995. Within the broadest scale, Australia is a major part of the Australasia biogeographic realm, as developed by the World Wide Fund for Nature. Based on this system, the world is also split into 14 terrestrial habitats, of which eight are shared by Australia. The Australian land mass is divided into 89 bioregions and 419 subregions. Each region is a land area made up of a group of interacting ecosystems that are repeated in similar form across the landscape. IBRA is updated periodically based on new data, mapping improvements, and review of the existing scheme. The most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mallee (biogeographic Region)
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.
