Baileyoxylon
''Baileyoxylon'' is a monotypic genus in the family Achariaceae. The sole described species is ''Baileyoxylon lanceolatum'' which is restricted to a very small part of the Wet Tropics of Queensland. It was described in the mid 20th century. Description ''Baileyoxylon lanceolatum'' is an evergreen tree growing up to about tall with medium grey bark and branchlets that are covered in rusty brown hairs. The dark green leaves are rather thick and measure up to long by wide, with 7–10 pairs of secondary veins either side of the midrib. They are obovate to oblong in shape, acuminate (pointed) at the tip and cuneate (tapering) at the base, and they have a relatively long petiole. The much-branched inflorescence can reach up to long and is also covered with rusty brown hairs. The small flowers are about long and have 5 petals. The globose orange fruit is, in botanical terminology, a berry containing one or two seeds. It measures around diameter. Taxonomy This species was fi ...

Achariaceae Genera
Achariaceae is a family of flowering plants consisting of 31 genera and about 155 species of tropical herbs, shrubs, and trees. The APG IV system has greatly expanded the scope of the family by including many genera previously classified in Flacourtiaceae. Molecular data strongly support the inclusion of this family in the order Malpighiales. The family is almost exclusively tropical and is best known as the source of chaulmoogra oil, formerly used to treat leprosy. Unlike other members of the former Flacourtiaceae now placed in the family Salicaceae, the genera of Achariaceae typically have cyanogenic glycosides. Genera The following 31 genera are accepted by Plants of the World Online Plants of the World Online (POWO) is an online taxonomic database published by the Royal Botanic Gardens, Kew. History Following the Convention on Biological Diversity, the Royal Botanic Gardens in Kew launched Plants of the World Online i ... : References Malpighiales famil ...

Cyril Tenison White
Cyril Tenison White (17 August 1890 – 15 August 1950) was an Australian botanist. Early life White was born in Brisbane, Queensland, to Henry White, a trade broker, and Louisa (''nee'' Bailey). He attended school at South Brisbane State School, and was appointed pupil-assistant to the Colonial Botanist of Queensland in 1905, a position previously held by his grandfather on his mother's side, Frederick Manson Bailey. White also succeeded his uncle, John Frederick Bailey, in becoming Queensland's Government Botanist in 1917. Personal life White married Henrietta Duncan Clark, a field naturalist and avid hiker, at South Brisbane on 21 October 1921. They married in Baptist tradition. Career As the Government Botanist, White aided farmers and naturalists in identifying noxious weeds and evaluating native species for pastures and fodder. Between 1915 and 1926, he worked on a 42-part series on weeds which appeared in the '' Queensland Agricultural Journal''. His books, ''An Elem ...

Australian Plant Name Index
The Australian Plant Name Index (APNI) is an online database of all published names of Australian vascular plants. It covers all names, whether current names, synonyms or invalid names. It includes bibliographic and typification details, information from the Australian Plant Census including distribution by state, links to other resources such as specimen collection maps and plant photographs, and the facility for notes and comments on other aspects. History Originally the brainchild of Nancy Tyson Burbidge, it began as a four-volume printed work consisting of 3,055 pages and containing over 60,000 plant names. Compiled by Arthur Chapman, it was part of the Australian Biological Resources Study (ABRS). In 1991 it was made available as an online database and handed over to the Australian National Botanic Gardens. Two years later, responsibility for its maintenance was given to the newly formed Centre for Plant Biodiversity Research. Scope Recognised by Australian herbaria as th ...

Plants Described In 1941
Plants are the eukaryotes that form the Kingdom (biology), kingdom Plantae; they are predominantly Photosynthesis, photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular organism, multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants (hornworts, liverworts ...

Endemic Flora Of Queensland
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 ...

Monotypic Malpighiales Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical system. ...

Australasian Virtual Herbarium
The ''Australasian Virtual Herbarium'' (AVH) is an online resource that allows access to plant specimen data held by various Australian and New Zealand herbaria. It is part of the Atlas of Living Australia (ALA), and was formed by the amalgamation of ''Australia's Virtual Herbarium'' and ''NZ Virtual Herbarium''. As of 12 August 2014, more than five million specimens of the 8 million and upwards specimens available from participating institutions have been databased. Uses This resource is used by academics, students, and anyone interested in research in botany in Australia or New Zealand, since each record tells all that is known about the specimen: where and when it was collected; by whom; its current identification together with the botanist who identified it; and information on habitat and associated species. ALA post processes the original herbarium data, giving further fields with respect to taxonomy and quality of the data. When interrogating individual specimen reco ...

Australian Tropical Rainforest Plants
Australian Tropical Rainforest Plants, also known as RFK, is an identification key giving details—including images, taxonomy, descriptions, range, habitat, and other information—of almost all species of flowering plants (i.e. trees, shrubs, vines, forbs, grasses and sedges, epiphytes, palms and pandans) found in tropical rainforests of Australia, with the exception of most orchids which are treated in a separate key called Australian Tropical Rainforest Orchids (see External links section). A key for ferns is under development. RFK is a project initiated by the Australian botanist Bernie Hyland. History The information system had its beginnings when Hyland started working for the Queensland Department of Forestry in the 1960s. It was during this time that he was tasked with the creation of an identification system for rainforest trees, but given no direction as to its format. Having little belief in single-access keys, he began work on creating a multi-access key (o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Biological Resources Study
Australian Biological Resources Study (ABRS) is a project undertaken by the Parks Australia Division of Australia's Department of Climate Change, Energy, the Environment and Water. Background ABRS was founded in 1973 from the recommendations of a 1972 Senate Select Committee report on Wildlife Conservation. ABRS was first set up as an Interim Council in 1973, followed by the establishment of the Study proper in 1978. The main aim of the Interim Council was to stimulate the study of taxonomy, distribution and ecology of Australia's biological resources via research grants, and for assessing the long term national requirements for taxonomic studies and maintenance of national collections of biological specimens. Research grants A core aim of the ABRS is to provide funding to support research on taxonomy and systematics for Australia's biota. The first grants offered by ABRS were to support the collection and scientific description of Australian plants and animals. Up to $75 ...
