Phrase Name
In Australian botany, a phrase name is an informal name given to a plant taxon that has not yet been given a formal scientific name. The term was adopted in 1992 by the Australian Herbarium Information Systems Committee. The species phrase name consists of four components — the generic name, "sp." (to indicate it is a species), an identifier (geographical or morphological) and a collector's name and number representing a herbarium specimen vouchering the concept of the new species. For example, the phrase name "''Derris'' sp. Wenlock River (B.Hyland 21082V)" refers to an unnamed species of ''Derris'', the specimen of which was collected by Bernard Hyland on the Wenlock River and whose herbarium number is 21082V. Likewise the phrase name "''Dryandra'' sp. 1 (A.S.George 16647)" refers to an unnamed ''Dryandra'' species to which belongs the herbarium specimen numbered 16647 collected by Alex George Alexander or Alex George may refer to: *Alex George (botanist) (born 1939), Australia ...

Taxon
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were set forth in Carl Linnaeus's Linnaean taxonomy, system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard de Jussieu, Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first mad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Derris
''Derris'' is genus of leguminous plants found in Southeast Asia and the southwest Pacific islands, including New Guinea. The roots of '' D. elliptica'' contain rotenone, a strong insecticide and fish poison. Despite the secondary compounds found in ''Derris'', they serve as food plants for many Lepidopteran larvae including ''Batrachedra'' spp. Selected species ''The Plant List'' includes the following: * ''Derris cumingii'' * ''Derris elegans'' * '' Derris elliptica'' * ''Derris ferruginea'' * ''Derris malaccensis'' * ''Derris marginata'' * ''Derris microphylla'' * ''Derris ovalifolia'' * '' Derris parviflora'' * ''Derris philippinensis'' * ''Derris polyantha'' * '' Derris robusta'' * ''Derris scandens'' * ''Derris trifoliata'', also known as the common derris See also * "Derris" insecticides based on rotenone * ''Millettia pinnata ''Millettia pinnata'' is a species of tree in the pea family, Fabaceae, native to eastern and tropical Asia, Australia, and Pacific islands. ...

Bernard Hyland
Bernard Hyland (Bernard Patrick Matthew Hyland, born 1937), known as Bernie Hyland, is an Australian botanist. He has contributed significantly to the understanding of Australian plants, in particular numerous species of his home and workplace in the Wet Tropics of Queensland. His contributions include many activities; he has collected eighteen thousand specimens and has named and scientifically described hundreds of species. He has expertise in the Australian rainforests’ rich diversity of species of the plant families Lauraceae and Myrtaceae. For example, his Lauraceae 1989 major revision of seven genera of one hundred and fifteen species, and his rainforest Myrtaceae 1983 major revision of seventy species of the genus ''Syzygium'' and allied genera. A major project he worked on for approximately 45 years is the ''Australian Tropical Rainforest Plants'' identification key and information system (RFK). He retired in 2002, continuing as a CSIRO Honorary Research Fellow an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wenlock River
The Wenlock River is a river located on the Cape York Peninsula in Far North Queensland, Australia. Course and features The river rises on the western slopes of the Great Dividing Range below Jacks Knob, west of Nundah homestead. The river flows generally north-west through tropical savanna plains and wetlands, joined by fifteen minor tributaries, before reaching its mouth and joining with the Ducie River on the western side of the peninsula at Port Musgrave, just north of Mapoon. Finally, the Wenlock River enters the Gulf of Carpentaria and descends over its course. The total catchment size is . The river has no water storage facilities built on it and there is little development within the drainage basin, resulting in a low population. In 2010, the Queensland Government declared the river a 'wild river', one of thirteen Queensland rivers that are free of dams, weirs, irrigation schemes and industrial development, and remain largely intact. Much of the river is border ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dryandra
''Banksia'' ser. ''Dryandra'' is a series of 94 species of shrub to small tree in the plant genus ''Banksia''. It was considered a separate genus named ''Dryandra'' until early 2007, when it was merged into ''Banksia'' on the basis of extensive molecular and morphological evidence that ''Banksia'' was paraphyletic with respect to ''Dryandra''. Taxonomy The dryandras were named in honour of Swedish botanist Jonas C. Dryander. The first specimens of a ''Dryandra'' were collected by Archibald Menzies, surgeon and naturalist to the Vancouver Expedition. At the request of Joseph Banks, Menzies collected natural history specimens wherever possible during the voyage. During September and October 1791, while the expedition were anchored at King George Sound, he collected numerous plant specimens, including the first specimens of '' B. sessilis'' (Parrotbush) and '' B. pellaeifolia''. Upon Menzies' return to England, he turned his specimens over to Banks; as with most othe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alex George (botanist)
Alexander Segger George (born 4 April 1939) is a Western Australian botanist. He is the authority on the plant genera ''Banksia'' and ''Dryandra''. The "bizarre" Restionaceae genus '' Alexgeorgea'' was named in his honour in 1976. Early life Alex Segger George was born in Western Australia on 4 April 1939. Career George joined the Western Australian Herbarium as a laboratory assistant at the age of twenty in 1959. He worked under Charles Gardner for a year before the latter's retirement, and partly credits him with rekindling an interest in banksias. In 1963 he graduated with a Bachelor of Arts from the University of Western Australia, and the following year added a botany major. Continuing at the Western Australian Herbarium as a botanist, in 1968 he was seconded as Australian Botanical Liaison Officer at the Royal Botanic Gardens in London. George also has an interest in history, especially historical biography of naturalists in Western Australia. He has published a number ...
