Acacia Pickardii
''Acacia pickardii'', commonly known as Pickard's wattle or birds nest wattle, is a tree or shrub belonging to the genus ''Acacia'' and the subgenus ''Phyllodineae'' native to eastern Australia. It is listed as a vulnerable species according to '' Environment Protection and Biodiversity Conservation Act 1999''. Description The shrub or small tree typically grows to a height of with a bushy habit. It is able to spread by suckering. The glabrous or subglabrous and scurfy branchlets have spinose stipules with a length of . Like most species of ''Acacia'' it has phyllodes rather than true leaves. The sessile, erect and terete phyllodes have a length of and a diameter of and are quite pungent. The rigid, minutely hirtellous, sometimes glabrous and usually scurfy phyllodes have a slender cusp with four obscure nerves and a basal gland. It blooms irregularly through the year, usually following rain events, and it produces simple inflorescences singly or in pairs in the axils with ...

Mary Tindale
Mary Douglas Tindale (19 September 1920 – 31 March 2011) was an Australian botanist specialising in pteridology (ferns) and the genera ''Acacia'' and ''Glycine''. Tindale was born in Randwick, New South Wales, the only child of George Harold Tindale and Grace Matilda Tindale. She attended primary school in New York while her father served as British Ambassador to the United States. She returned to Sydney, Australia to attend high school at Abbotsleigh. Tindale earned a B.Sc. in Botany with Honours from Sydney University, as well as a master's degree from the same university.

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of South Australia
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Acacia Species
Several Cladistics, cladistic analyses have shown that the genus ''Acacia sensu lato, Acacia'' is not monophyletic. While the subg. ''Acacia'' and subg. ''Phyllodinae'' are monophyletic, subg. ''Aculeiferum'' is not. This subgenus consists of three clades. Therefore, the following list of ''Acacia'' species cannot be maintained as a single entity, and must either be split up, or broadened to include species previously not in the genus. This genus has been provisionally divided into 5 genus, genera, ''Acacia'', ''Vachellia'', ''Senegalia'', ''Acaciella'' and ''Mariosousa''. The proposed type species of ''Acacia'' is ''Acacia penninervis''. Which of these segregate genera is to retain the name ''Acacia'' has been controversial. The genus was previously typified with the African species ''Acacia scorpioides'' (L.) W.F.Wright, a synonym of ''Acacia nilotica'' (L.) Delile. Under the original typification, the name ''Acacia'' would stay with the group of species currently recognized ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Australian Herbarium
The Western Australian Herbarium is the State Herbarium in Perth, Western Australia. It is part of the State government's Department of Parks and Wildlife, and has responsibility for the description and documentation of the flora of Western Australia. It has the Index Herbariorum code of PERTH. The Hebarium forms part of the Australasian Virtual Herbarium. The Herbarium is linked to the Western Australian 'Regional Herbaria Network' – which links approximately 84 regional community groups which have local reference collections. In 2000, with the Wildflower Society of Western Australia and the Botanic Gardens and Parks Authority it published '' The Western Australian Flora – A Descriptive Catalogue''. History The Herbarium was formed as the amalgamation of three separate government department herbaria: those of the Western Australian Museum, the Department of Agriculture, and the "forest herbarium" maintained by the Conservator of Forests. The first of these was formed by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Atriplex
''Atriplex'' () is a plant genus of about 250 species, known by the common names of saltbush and orache (; also spelled orach). It belongs to the subfamily Chenopodioideae of the family Amaranthaceae ''s.l.''. The genus is quite variable and widely distributed. It includes many desert and seashore plants and halophytes, as well as plants of moist environments. The generic name originated in Latin and was applied by Pliny the Elder to the edible oraches. The name saltbush derives from the fact that the plants retain salt in their leaves; they are able to grow in areas affected by soil salination. Description Species of plants in genus ''Atriplex'' are annual or perennial herbs, subshrubs, or shrubs. The plants are often covered with bladderlike hairs, that later collapse and form a silvery, scurfy or mealy surface, rarely with elongate trichomes. The leaves are arranged alternately along the branches, rarely in opposite pairs, either sessile or on a petiole, and are sometim ...

Gibber
A desert pavement, also called reg (in the western Sahara), serir (eastern Sahara), gibber (in Australia), or saï (central Asia) is a desert surface covered with closely packed, interlocking angular or rounded rock fragments of pebble and cobble size. They typically top alluvial fans. Desert varnish collects on the exposed surface rocks over time. Geologists debate the mechanics of pavement formation and their age. Formation Several theories have been proposed for the formation of desert pavements. A common theory suggests that they form through the gradual removal of sand, dust and other fine-grained material by the wind and intermittent rain, leaving the larger fragments behind. The larger fragments are shaken into place through the forces of rain, running water, wind, gravity, creep, thermal expansion and contraction, wetting and drying, frost heaving, animal traffic, and the Earth's constant microseismic vibrations. The removal of small particles by wind does not continue ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Birdsville Track
The Birdsville Track is a notable outback road in Australia. The track runs between Birdsville in south-western Queensland and Marree, a small town in the north-eastern part of South Australia. It traverses three deserts along the route, the Strzelecki Desert, Sturt Stony Desert and Tirari Desert. Originally the track was of poor quality and suitable for high-clearance four-wheel drive vehicles only, but it is now a graded dirt road and a popular tourist route. It is also used by cattle trucks carrying livestock. The track passes through one of the driest parts of Australia with an average rainfall of less than 100 mm annually. The area is extremely barren, dry and isolated, and travellers should carry water and supplies in case of emergencies. History The track was opened in the 1860s to walk cattle from northern Queensland and the Northern Territory to the nearest railhead in Port Augusta which was later moved to Marree.
