Austrostipa Crinita
''Austrostipa crinita'' is a species of grass that grows in coastal parts of midwest Western Australia. Description It is a tufted perennial bunchgrass from 40 centimetres to 70 centimetres in height. Flowers are yellow or brown. It reproduces asexually by short rhizomes. Taxonomy It was first collected from Shark Bay in Western Australia by Charles Gaudichaud-Beaupré, botanist to the expedition of Louis de Freycinet. It was published by Gaudichaud-Beaupré in 1829 under the name ''Stipa crinita''. That name remained current until 1996, when the Australian species of ''Stipa'' were recognised as meriting their own genus. Thus '' Austrostipa'' was erected, and this and other species were transferred into it. Distribution and habitat It occurs on sand and limestone in coastal areas of midwest Western Australia, including offshore islands such as those of the Houtman Abrolhos The Houtman Abrolhos (often called the Abrolhos Islands) is a chain of 122 islands and associated c ...

Western Australia
Western Australia (WA) is the westernmost state of Australia. 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 land area of , and is also the List of country subdivisions by area, second-largest subdivision of any country on Earth. Western Australia has a diverse range of climates, including tropical conditions in the Kimberley (Western Australia), Kimberley, deserts in the interior (including the Great Sandy Desert, Little Sandy Desert, Gibson Desert, and Great Victoria Desert) and a Mediterranean climate on the south-west and southern coastal areas. the state has 2.965 million inhabitants—10.9 percent of the national total. Over 90 percent of the state's population live in the South-West Land Division, south-west corner and around 80 percent live in the state capital Perth, leaving the remainder ...

Bunchgrass
Tussock grasses or bunch grasses are a group of grass species in the family Poaceae. They usually grow as singular plants in clumps, tufts, hummocks, or bunches, rather than forming a sod or lawn, in meadows, grasslands, and prairies. As perennial plants, most species live more than one season. Tussock grasses are often found as forage in pastures and ornamental grasses in gardens. Many species have long roots that may reach or more into the soil, which can aid slope stabilization, erosion control, and soil porosity for precipitation absorption. Also, their roots can reach moisture more deeply than other grasses and annual plants during seasonal or climatic droughts. The plants provide habitat and food for insects (including Lepidoptera), birds, small animals and larger herbivores, and support beneficial soil mycorrhiza. The leaves supply material, such as for basket weaving, for indigenous peoples and contemporary artists. Tussock and bunch grasses occur in almost any h ...

Rhizome
In botany and dendrology, a rhizome ( ) is a modified subterranean plant stem that sends out roots and Shoot (botany), shoots from its Node (botany), nodes. Rhizomes are also called creeping rootstalks or just rootstalks. Rhizomes develop from axillary buds and grow horizontally. The rhizome also retains the ability to allow new shoots to grow upwards. A rhizome is the main stem of the plant that runs typically underground and horizontally to the soil surface. Rhizomes have nodes and internodes and auxiliary buds. Roots do not have nodes and internodes and have a root cap terminating their ends. In general, rhizomes have short internodes, send out roots from the bottom of the nodes, and generate new upward-growing shoots from the top of the nodes. A stolon is similar to a rhizome, but stolon sprouts from an existing stem having long internodes and generating new shoots at the ends, they are often also called runners such as in the strawberry plant. A stem tuber is a thickene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shark Bay
Shark Bay () is a World Heritage Site in the Gascoyne region of Western Australia. The area is located approximately north of Perth, on the westernmost point of the Australian continent. UNESCO's listing of Shark Bay as a World Heritage Site reads: The bay features Australia's most abundant marine ecosystems. It is a popular fishing spot. History The record of Indigenous Australians, Australian Aboriginal occupation of Shark Bay extends to years Before Present, BP. At that time most of the area was dry land, and rising sea levels flooded Shark Bay between BP and BP. A considerable number of Aboriginal midden sites have been found, especially on Peron Peninsula and Dirk Hartog Island, which provide evidence of some of the foods gathered from the waters and nearby land areas. An expedition led by Dirk Hartog happened upon the area in 1616, becoming the second group of Europeans known to have visited Australia, after the crew of ''Duyfken'' under Willem Janszoon had visi ...

Charles Gaudichaud-Beaupré
Charles Gaudichaud-Beaupré (September 4, 1789 – January 16, 1854) was a French botanist. Biography Gaudichaud was born in Angoulême, to J-J. Gaudichaud and Rose (Mallat) Gaudichaud. He studied pharmacology informally at Cognac and Angoulême, and then under Robiquet in Paris, where he acquired a knowledge of botany from Desfontaines and Louis Richard. In April 1810, he was appointed pharmacist in the military marine, and from July 1811 to the end of 1814, he served in Antwerp. He also studied chemistry and herbology. His greatest claim to fame was serving as botanist on a circumglobal expedition from 1817 to 1820. He accompanied Freycinet, who made the expedition on the ships ''Uranie'' and ''Physicienne''. The wreck of the ''Uranie'' in the Falkland Islands, at the close of 1819, deprived him of more than half the botanical collections he had made in various parts of the world. He is also known for his collections in Australia. In 1831, Gaudichaud sailed on ''L'Hermini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Louis De Freycinet
Louis Claude de Saulces de Freycinet (7 August 1779 – 18 August 1841) was a French Navy officer. He circumnavigated the Earth, and in 1811 published the first map to show a full outline of the coastline of Australia. Biography He was born at Montélimar, Drôme. Louis-Claude de Saulces de Freycinet was his full name (many calling him Louis de Freycinet). His mother was Élisabeth-Antoinette-Catherine Armand. He had three brothers, Louis-Henri de Saulces de Freycinet, André-Charles de Saulces de Freycinet and the youngest, Frédéric-Casimir de Saulces de Freycinet (father of Charles de Freycinet). Louis-Claude was the second oldest. In 1793 he joined the French Navy as a midshipman, and took in several engagements against the British. In 1800, Freycinet was appointed to an exploration expedition to Southern and South-Western coasts of Australia under Nicolas Baudin, on ''Naturaliste'' and ''Géographe''.

Stipa
''Stipa'' is a genus of 141 species of large Perennial plant, perennial hermaphrodite, hermaphroditic grasses collectively known as feather grass, needle grass, and spear grass. They are placed in the subfamily Pooideae and the tribe Stipeae, which also contains many species formerly assigned to ''Stipa'', which have since been reclassified into new genera. Many species are important forage crops. Several species such as ''Stipa brachytricha'', ''S. arundinacea'', ''S. splendens'', ''S. calamagrostis'', ''S. gigantea'' and ''S. pulchra'' are used as ornamental plants. One former species, esparto grass (''Macrochloa tenacissima''), is used for crafts and extensively in paper making. It is a coarse grass with inrolled leaves and a panicle patterned inflorescence. Ecology Species of the genus ''Stipa'' can occur in grasslands or in savanna habitats. Certain specific prairie plant associations are dominated by grasses of the genus ''Stipa'', which genus often lends its name to the ...

Houtman Abrolhos
The Houtman Abrolhos (often called the Abrolhos Islands) is a chain of 122 islands and associated coral reefs in the Indian Ocean off the west coast of Australia about west of Geraldton, Western Australia. It is the southernmost true coral reef in the Indian Ocean, and one of the highest latitude reef systems in the world. It is one of the world's most important seabird breeding sites, and the centre of Western Australia's largest single-species fishery, the western rock lobster fishery. It has a small seasonal population of fishermen, and a limited number of tourists are permitted for day trips, but most of the land area is off-limits as a conservation habitat. It is the site of numerous shipwrecks, the most famous being two Dutch ships: , which was wrecked in 1629 (followed by massacre of over 100 survivors by mutineers), and , wrecked in 1727. The islands are an unincorporated area with no municipal government, subject to direct administration of the Government of Wester ...
