Ricinocarpos Brevis
''Ricinocarpos brevis'' is a species of flowering plant in the family Euphorbiaceae and is endemic to inland Western Australia. It is a monoecious, densely-branched shrub with narrowly oblong leaves and male and female flowers arranged singly or in small groups. Description ''Ricinocarpos brevis'' is a monoecious shrub that typically grows to height of and is densely and intricately branched. The leaves are densely hairy and narrowly oblong, mostly long and wide on a short petiole. The flowers are arranged singly, or with two female, or one female and one or two male flowers. The flowers are conspicuous and arranged on a pedicel densely covered with woolly white, star-shaped hairs. Male flowers are on a thin pedicel long, the sepals covered with woolly, white, star-shaped hairs. Male flowers have egg-shaped, white petals outlined in red, long and wide. Female flowers are usually on a stout pedicel long, the sepals densely hairy, the petals white but turning brown, long a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rodney John Francis Henderson
Rodney John Francis Henderson (15 January 1938 – 9 March 2025) was an Australian botanist, who specialised in taxonomy. He worked for more than 48 years for the Queensland Public Service, 41 of those years at the Queensland Herbarium until his retirement in 2002. The families he studied included the Solanaceae, Liliaceae, Euphorbiaceae and Rubiaceae. There are about 3,500 labelled specimens in Australian herbaria collected by Henderson, sometimes with other botanists. He was often sought after as an expert in the application of the International Code of Botanical Nomenclature because of his knowledge of the code and of botanical Latin and Greek. Henderson was actively involved with the Australian Systematic Botany Society from its formation in 1973 and was its second vice-president. He was appointed Australian Botanical Liaison Officer to Kew Gardens Kew Gardens is a botanical garden, botanic garden in southwest London that houses the "largest and most diverse botany, bo ...

Austrobaileya (journal)
''Austrobaileya'' is a peer-reviewed annual scientific journal published by the Queensland Herbarium. It covers systematic botany, relating to the flora of Queensland and in particular tropical Australia. It was established in 1968 as ''Contributions from the Queensland Herbarium'', obtaining its current title in 1977, with volume numbering restarted at 1. Since 2015, the journal is published open access, with print versions available on subscription. Older issues are available online from JSTOR. The journal was named after the Queensland endemic genus '' Austrobaileya''. Abstracting and indexing The journal is abstracted and indexed in Biological Abstracts, BIOSIS Previews, CAB Abstracts, and Scopus Scopus is a scientific abstract and citation database, launched by the academic publisher Elsevier as a competitor to older Web of Science in 2004. The ensuing competition between the two databases has been characterized as "intense" and is c .... References External links * ...

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 ...

Malpighiales Of Australia
The Malpighiales comprise one of the largest orders of flowering plants. The order is very diverse, with well-known members including willows, violets, aspens and poplars, poinsettia, corpse flower, coca plant, cassava, flaxseed, castor bean, Saint John's wort, passionfruit, mangosteen, and manchineel tree. The order is not part of any of the classification systems based only on plant morphology and the relationships of its diverse members can be hard to recognize except with molecular phylogenetic evidence. Molecular clock calculations estimate the origin of stem group Malpighiales at around 100 million years ago ( Mya) and the origin of crown group Malpighiales at about 90 Mya. The Malpighiales contain about 36 families and more than species, about 7.8% of the eudicots. Taxonomy The Malpighiales include the following 36 families, according to the APG IV system of classification: *Achariaceae * Balanopaceae *Bonnetiaceae *Calophyllaceae * Caryocaraceae *Centroplacaceae ...

Ricinocarpos
''Ricinocarpos'' is a genus of evergreen flowering plants in the family Euphorbiaceae and is endemic to Australia. Plants in the genus ''Ricinocarpos'' are monoecious shrubs with leaves arranged alternately along the branches, the edges curved downwards or rolled under. Male flowers are arranged singly or in racemes at the ends of branchlets, with four to six sepals that are fused at the base. There are four to six petals that are longer than the sepals, with many stamens fused to form a central Column (botany), column. Female flowers are arranged singly and are similar to male flowers but with three Style (botany), styles fused at the base and with a deeply branched tip. The fruit is a Capsule (fruit), capsule containing seeds with an elaiosome. The genus ''Ricinocarpus'' was first formally described in 1817 by René Louiche Desfontaines in ''Mémoires du Muséum d'histoire naturelle''. The entire genus is endemic to Australia.Halford, D.A. & Henderson, J.F. (2007). A taxonomic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Department Of Biodiversity, Conservation And Attractions (Western Australia)
The Department of Biodiversity, Conservation and Attractions (DBCA) is the Government of Western Australia, 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. Status Parks and Wildlife Service The Formerly Department of Parks and Wildlife. the Parks and Wildlife Servi ...
