Astrebla
''Astrebla'' is a small genus of xerophytic (adapted to survive in an environment with little liquid water) grasses found only in Australia. They are the dominant grass across much of the continent. They are commonly known as Mitchell grass after Scottish explorer, Thomas Mitchell (1792-1855), who first collected a specimen near Bourke in New South Wales. Mitchell grasses grow on clay soils, mainly between an upper limit of and a lower limit of average annual rainfall, and at even lower rainfall in depressions where the water concentrates following rains, for example in Sturt's Stony Desert. Mitchell grasses are deep-rooted and become dormant during drought, allowing them to survive extended periods without rainfall. They are commonly found clumped together and reaching one metre high, providing habitat for organisms such as mammals. ; Species See also * List of Poaceae genera The true grasses ( Poaceae) are one of the largest plant families, with around 12,000 species ...

Thomas Mitchell (explorer)
Sir Thomas Livingstone Mitchell (15 June 1792 – 5 October 1855), surveyor and explorer of Southeastern Australia, was born at Grangemouth in Stirlingshire, Scotland. In 1827 he took up an appointment as Assistant Surveyor General of New South Wales. The following year he became Surveyor General and remained in this position until his death. Mitchell was knighted in 1839 for his contribution to the surveying of Australia. Early life Born in Scotland on 15 June 1792, he was son of John Mitchell of Carron Works and was brought up from childhood by his uncle, Thomas Livingstone of Parkhall, Stirlingshire. Peninsular War On the death of his uncle, he joined the British army in Portugal as a volunteer in the Peninsular War, at the age of sixteen. On 24 June 1811, at the age of nineteen, he received his first commission as 2nd Lieutenant in the 1st Battalion 95th Rifles (later the Rifle Brigade / Royal Green Jackets).

List Of Poaceae Genera
The true grasses ( Poaceae) are one of the largest plant families, with around 12,000 species and roughly 800 genera. They contain, among others, the cereal crop species and other plants of economic importance, such as the bamboos, and several important weeds. Grasses probably originated in the understory of tropical rainforests in the Late Cretaceous, but have since come to occupy a wide range of different habitats. Notably, they are the dominant species in grasslands, open habitats that cover around one fifth of the earth's terrestrial surface. The C4 photosynthetic pathway has evolved at least 22 times independently in the grasses; C4 species are more competitive than C3 plants in open habitats with high light intensity and warm temperatures. The deeper relationships in the family have been resolved by recent molecular phylogenetic work. This has been translated into a modern classification which divides the grasses into twelve subfamilies and a number of tribes, with ...

Poales Of Australia
The Poales are a large order of flowering plants in the monocotyledons, and includes families of plants such as the grasses, bromeliads, and sedges. Sixteen plant families are currently recognized by botanists to be part of Poales. Description The flowers are typically small, enclosed by bracts, and arranged in inflorescences (except in three species of the genus ''Mayaca'', which possess very reduced, one-flowered inflorescences). The flowers of many species are wind pollinated; the seeds usually contain starch. Taxonomy The APG III system (2009) accepts the order within a monocot clade called commelinids, and accepts the following 16 families: The earlier APG system (1998) adopted the same placement of the order, although it used the spelling "commelinoids". It did not include the Bromeliaceae and Mayaceae, but had the additional families Prioniaceae (now included in Thurniaceae), Sparganiaceae (now in Typhaceae), and Hydatellaceae (now transferred out of the monocots; r ...

Bunchgrasses Of Australasia
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 habitat w ...

Chloridoideae
Chloridoideae is one of the largest subfamilies of grasses, with roughly 150 genera and 1,600 species, mainly found in arid tropical or subtropical grasslands. Within the PACMAD clade, their sister group are the Danthonioideae. The subfamily includes widespread weeds such as Bermuda grass (''Cynodon dactylon'') or goosegrass (''Eleusine indica''), but also millet species grown in some tropical regions, namely finger millet (''Eleusine coracana'') and teff (''Eragrostis tef''). With the exception of some species in ''Ellisochloa'' and Eleusine indica, most of the subfamily's species use the C4 photosynthetic pathway. The first evolutionary transition from C3 to C4 photosynthesis in the grasses probably occurred in this subfamily, around 32 to 25 million years ago in the Oligocene. Phylogeny Relationships of tribes in the Chloridoideae according to a 2017 phylogenetic classification, also showing the Danthonioideae as sister group: The following genera have not been assigned t ...

Bourke, New South Wales
Bourke is a town in the north-west of New South Wales, Australia. The administrative centre and largest town in Bourke Shire, Bourke is approximately north-west of the state capital, Sydney, on the south bank of the Darling River. it is also situated: * 137 kilometres south of Barringun and the Queensland - New South Wales Border * 256 kilometres (159 mi) south of Cunnamulla * 454 kilometres (282 mi) south of Charleville History The location of the current township of Bourke on a bend in the Darling River is the traditional country of the Ngemba people. The first European-born explorer to encounter the river was Charles Sturt in 1828 who named it after Sir Ralph Darling, Governor of New South Wales. Having struck the region during an intense drought and a low river, Sturt dismissed the area as largely uninhabitable and short of any features necessary for establishing reliable industry on the land. It was not until the mid-1800s following a visit by colonial surveyor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lindl
John Lindley FRS (5 February 1799 – 1 November 1865) was an English botanist, gardener and orchidologist. Early years Born in Catton, near Norwich, England, John Lindley was one of four children of George and Mary Lindley. George Lindley was a nurseryman and pomologist and ran a commercial nursery garden. Although he had great horticultural knowledge, the undertaking was not profitable and George lived in a state of indebtedness. As a boy he would assist in the garden and also collected wild flowers he found growing in the Norfolk countryside. Lindley was educated at Norwich School. He would have liked to go to university or to buy a commission in the army but the family could not afford either. He became Belgian agent for a London seed merchant in 1815. At this time Lindley became acquainted with the botanist William Jackson Hooker who allowed him to use his botanical library and who introduced him to Sir Joseph Banks who offered him employment as an assistant in his herba ...

Common Name
In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrasted with the scientific name for the same organism, which is Latinized. A common name is sometimes frequently used, but that is not always the case. In chemistry, IUPAC defines a common name as one that, although it unambiguously defines a chemical, does not follow the current systematic naming convention, such as acetone, systematically 2-propanone, while a vernacular name describes one used in a lab, trade or industry that does not unambiguously describe a single chemical, such as copper sulfate, which may refer to either copper(I) sulfate or copper(II) sulfate. Sometimes common names are created by authorities on one particular subject, in an attempt to make it possible for members of the general public (including such interested par ...
