Lawrencia Densiflora
''Lawrencia densiflora'' is a species of plant in the mallow family, Malvaceae. It is endemic to Western Australia Description ''L. densiflora'' is a perennial shrub/herb, growing to a height from 0.07 to 0.6 m. The stems are hairy. The leaves are irregularly lobed, 10 to 40 mm long and 5 to 20 mm wide, with stellate hairs. The flowers have both a calyx and a corolla, and are yellow to cream and seen between July and October.

Ronald Melville (botanist)
Ronald Melville (12 March 1903 – 6 August 1985) He was an English botanist, based at the Royal Botanic Gardens Kew. He is chiefly remembered for his wartime research into rosehips as a source of vitamin C, prompted by the epidemic of scurvy amongst children owing to the reduced importation of fresh fruit. His research concluded that hips from the common Dog Rose ''Rosa canina'' held the highest concentration of the vitamin. In later years, he challenged the two-species taxonomy of the British elms proposed by Richens,Richens, R. H. (1984) ''Elm'', Cambridge University Press. identifying five distinct species, several varieties and numerous complex hybrids.Melville, R. (1978).

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 ...

Plant
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 ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Malvaceae
Malvaceae, or the mallows, is a family of flowering plants estimated to contain 244 genera with 4225 known species. Well-known members of economic importance include okra, cotton, cacao and durian. There are also some genera containing familiar ornamentals, such as ''Alcea'' (hollyhock), ''Malva'' (mallow), and ''Tilia'' (lime or linden tree). The largest genera in terms of number of species include ''Hibiscus'' (300 species), ''Sterculia'' (250 species), ''Dombeya'' (250 species), '' Pavonia'' (200 species) and '' Sida'' (200 species). Taxonomy and nomenclature The circumscription of the Malvaceae is controversial. The traditional Malvaceae '' sensu stricto'' comprise a very homogeneous and cladistically monophyletic group. Another major circumscription, Malvaceae ''sensu lato'', has been more recently defined on the basis that genetics studies have shown the commonly recognised families Bombacaceae, Tiliaceae, and Sterculiaceae, which have always been considered closely allie ...

Western Australia
Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a total land area of . It is the second-largest country subdivision in the world, surpassed only by Russia's Sakha Republic. the state has 2.76 million inhabitants percent of the national total. The vast majority (92 percent) live in the south-west corner; 79 percent of the population lives in the Perth area, leaving the remainder of the state sparsely populated. The first Europeans to visit Western Australia belonged to the Dutch Dirk Hartog expedition, who visited the Western Australian coast in 1616. The first permanent European colony of Western Australia occurred following the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Botanical Provinces Of Western Australia
The ''botanical provinces of Western Australia (or Beard's Provinces)'' delineate "natural" phytogeographic regions of WA, based on climate and types of vegetation. John Stanley Beard, in "Plant Life of Western Australia" (p. 29-37) gives a short history of the various mappings. In 1906, Ludwig Diels divided the state into an Eremaean Province and a South-West Province (together with further subdivisions), based on rainfall ranges, types of vegetation, and species' distributions (Beard, 2015:p. 30). In 1944, C.A. Gardner modified Diels' description, adding the Northern Province, which comprised the Kimberley and Pilbara districts. With Bennetts in 1956, he further refined this to give state-wide divisions. Subsequent work by Beard and others gave the current set of provinces used by Florabase in its descriptions of plants. (See, for example, the entry where ''Parsonsia diaphanophleba'' is described as being found in Beard's South-West Province.) ''Beard's provi ...

Interim Biogeographic Regionalisation For Australia
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] |
