Iridaceae
Iridaceae is a family of plants in order Asparagales, taking its name from the irises, meaning rainbow, referring to its many colours. There are 66 accepted genera with a total of c. 2244 species worldwide (Christenhusz & Byng 2016). It includes a number of other well known cultivated plants, such as freesias, gladioli and crocuses. Members of this family are perennial plants, with a bulb, corm or rhizome. The plants grow erect, and have leaves that are generally grass-like, with a sharp central fold. Some examples of members of this family are the blue flag and yellow flag. Name and history The family name is based on the genus ''Iris'', the largest and best known genus in Europe. This genus dates from 1753, when it was coined by Swedish botanist, Carl Linnaeus. Its name derives from the Greek goddess, Iris, who carried messages from Olympus to earth along a rainbow, whose colours were seen by Linnaeus in the multi-hued petals of many of the species. The family is current ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Badgingarra, Western Australia
Badgingarra is a small town in the Wheatbelt region of Western Australia, about north of Perth in the Shire of Dandaragan. It lies on the Brand Highway adjacent to the Badgingarra National Park. History The town was gazetted in 1955 and takes its name from nearby Badgingarra Pool. "Badgingarra" is a Noongar word said to mean "water by the manna gums". The district was originally surveyed in the 1880s; however, due to the widespread presence of poisonous plants in the area and non-conducive soil types, the land was not developed for agriculture. Little settlement occurred until the 1950s, when the use of trace elements such as zinc and copper in fertilisers allowed for farming to occur on the sandy soils around Badgingarra. In 1955, sufficient population growth had occurred for the gazettal of a townsite to support the settlers. In 1959, the state government established the Badgingarra Research Station, to assist farmers in the development of their enterprises. In 1965, a pr ...

Patersonia
''Patersonia'', commonly known as native iris or native flag and are native to areas from Malesia to Australia. Description They are perennials with basal leaves growing from a woody rhizome that in some species extends above ground to form a short trunk. The leaves are tough and fibrous, often with adaptations for conserving moisture, such as stomata sunk in grooves, a thickened cross-section, marginal hairs, and thickened margins. The flowers appear from between a pair of bracts on a leafless stem. They have three large outer tepals that are usually blue to violet, and three tiny inner tepals. There are three stamens fused at the base to form a tube around the longer gynoecium, style, which bears a flattened carpel, stigma.Goldblatt, P. (2011).

Flora Of Western Australia
The flora of Western Australia comprises 10,551 published native vascular plant species and a further 1,131 unpublished species. They occur within 1,543 genera from 211 families; there are also 1,317 naturalised alien or invasive plant species more commonly known as weeds. There are an estimated 150,000 cryptogam species or nonvascular plants which include lichens, and fungi although only 1,786 species have been published, with 948 algae and 672 lichen the majority. History Indigenous Australians have a long history with the flora of Western Australia. They have for over 50,000 years obtained detailed information on most plants. The information includes its uses as sources for food, shelter, tools and medicine. As Indigenous Australians passed the knowledge along orally or by example, most of this information has been lost, along many of the names they gave the flora. It was not until Europeans started to explore Western Australia that systematic written details of the flora comme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 1990
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 los ...
