Friedrich Markgraf
Friedrich Markgraf (1 February 1897 in Berlin-Friedenau – 8 March 1987 in Zurich) was a German botanist. Life and work After secondary school, Markgraf studied biology at the Friedrich Wilhelm University Berlin. In 1922 he was awarded a Ph.D. for a thesis on the subject of a botanic-ecological study of the Bredower forest near Berlin. After his habilitation he became first a professor of botany at the Friedrich Wilhelm University in Berlin and then at the Ludwig Maximilian University of Munich and director of the Botanical Garden Munich-Nymphenburg (1956-1958). Markgraf was also visiting professor of botany at the University of Zurich. During his teaching and research activities, he was primarily concerned with questions of botanical systematics, plant morphology and phytogeography and he also undertook research while travelling in the Mediterranean. In particular he made an important start on the study of the local flora of Albania. He acted as the Regional Adviser o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Stanley Thatcher Blake
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cerbera
''Cerbera'' is a genus of evergreen small trees or shrubs, native to tropical Asia, Australia, Madagascar, and various islands in the Indian Ocean and the western Pacific Ocean. Three trees of this genus are mangroves, ''Cerbera floribunda'', ''Cerbera manghas'' and ''Cerbera odollam''. The leaves are alternate and lack interpetiolar stipules. The tubular corollas are actinomorphic, i.e. they are symmetric and can be divided in halves along any diameter. All trees contain a white latex. The fruits are drupes. The genus is named after Cerberus because all its parts are poisonous : they contain cerberin, a cardiac glycoside, a substance that blocks electric impulses in the body (including the beating of the heart). Therefore, it is advised to avoid using wood from Cerbera species due to their toxicity, and as their smoke may cause lethal poisoning. The genus is related to ''Cerberiopsis'',Potgieter, K., and V.

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 record ...

Australian Government
The Australian Government, also known as the Commonwealth Government, is the national government of Australia, a federal parliamentary constitutional monarchy. Like other Westminster-style systems of government, the Australian Government is made up of three branches: the executive (the prime minister, the ministers, and government departments), the legislative (the Parliament of Australia), and the judicial. The legislative branch, the federal Parliament, is made up of two chambers: the House of Representatives (lower house) and Senate (upper house). The House of Representatives has 151 members, each representing an individual electoral district of about 165,000 people. The Senate has 76 members: twelve from each of the six states and two each from Australia's internal territories, the Australian Capital Territory and Northern Territory. The Australian monarch, currently King Charles III, is represented by the governor-general. The Australian Government in its executive ca ...

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 (or polyc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Plant Names Index
The International Plant Names Index (IPNI) describes itself as "a database of the names and associated basic bibliographical details of seed plants, ferns and lycophytes." Coverage of plant names is best at the rank of species and genus. It includes basic bibliographical details associated with the names. Its goals include eliminating the need for repeated reference to primary sources for basic bibliographic information about plant names. The IPNI also maintains a list of standardized author abbreviations. These were initially based on Brummitt & Powell (1992), but new names and abbreviations are continually added. Description IPNI is the product of a collaboration between The Royal Botanic Gardens, Kew (Index Kewensis), The Harvard University Herbaria (Gray Herbarium Index), and the Australian National Herbarium ( APNI). The IPNI database is a collection of the names registered by the three cooperating institutions and they work towards standardizing the information. The stan ...

Southern Cassowary
The southern cassowary (''Casuarius casuarius''), also known as double-wattled cassowary, Australian cassowary, or two-wattled cassowary, is a large flightless black bird, found in Indonesia, Papua New Guinea, and northeastern Australia. It is one of the three living species of cassowary, alongside the dwarf cassowary and the northern cassowary. It is a ratite and therefore related to the emu, ostriches, Rhea (bird), rheas and Kiwi (bird), kiwi. The Australian population is listed as Endangered species, Endangered under federal and Queensland state legislation. Taxonomy Presently, most authorities consider the southern cassowary monotypic, but several subspecies have been described. It has proven very difficult to confirm the validity of these due to individual variations, age-related variations, the relatively few available Zoological specimen, specimens (and the bright skin of the head and neck – the basis upon which several subspecies have been described – fades in spe ...
