Hawker, South Australia
Hawker is a town and a locality in the Flinders Ranges area of South Australia, north of Adelaide. It is in the Flinders Ranges Council, the state Electoral district of Stuart and the federal Division of Grey. At the 2016 census, the locality had a population of 341 of which 237 lived in its town centre. History The town was surveyed during March 1880 and was proclaimed on 1 July 1880. It was named after G. C. Hawker who was a member of the South Australian Parliament for the years 1858–1865 and 1875–1883.

Rodinia
Rodinia (from the Russian родина, ''rodina'', meaning "motherland, birthplace") was a Mesoproterozoic and Neoproterozoic supercontinent that assembled 1.26–0.90 billion years ago and broke up 750–633 million years ago. were probably the first to recognise a Precambrian supercontinent, which they named 'Pangaea I'. It was renamed 'Rodinia' by who also were the first to produce a reconstruction and propose a temporal framework for the supercontinent. Rodinia formed at c. 1.23 Ga by accretion and collision of fragments produced by breakup of an older supercontinent, Columbia, assembled by global-scale 2.0–1.8 Ga collisional events.; Rodinia broke up in the Neoproterozoic with its continental fragments reassembled to form Pannotia 633–573 million years ago. In contrast with Pannotia, little is known yet about the exact configuration and geodynamic history of Rodinia. Paleomagnetic evidence provides some clues to the paleolatitude of individual pieces of the Ea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lily
''Lilium'' () is a genus of Herbaceous plant, herbaceous flowering plants growing from bulbs, all with large prominent flowers. They are the true lilies. Lilies are a group of flowering plants which are important in culture and literature in much of the world. Most species are native to the northern hemisphere and their range is temperate climates and extends into the subtropics. Many other plants have "lily" in their common names, but do not belong to the same genus and are therefore not true lilies. Description Lilies are tall perennial plant, perennials ranging in height from . They form naked or tunicless scaly underground bulbs which are their organs of perennation. In some North American species the base of the bulb develops into rhizomes, on which numerous small bulbs are found. Some species develop stolons. Most bulbs are buried deep in the ground, but a few species form bulbs near the soil surface. Many species form stem-roots. With these, the bulb grows naturally at s ...

Hibbertia
''Hibbertia'', commonly known as guinea flowers, is a genus of flowering plants in the family Dilleniaceae. They are usually shrubs with simple leaves and usually yellow flowers with five sepals and five petals. There are about 400 species, most of which occur in Australia but a few species occur in New Guinea, New Caledonia, Fiji and Madagascar. Description Plants in the genus ''Hibbertia'' are usually shrubs, rarely climbers, and often form mats. Their leaves are usually arranged alternately along the stems, usually sessile, clustered on short side-branches, and have smooth, rarely toothed or lobed edges. The flowers are usually arranged singly in leaf axils or on the ends of stems and have five sepals, two "outer" sepals slightly overlapping the three "inner" ones. There are five yellow, rarely orange, petals and the stamens are usually arranged in three to five groups, sometimes on only one side of the carpels. There are between two and five carpels, usually free from each o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grevillea
''Grevillea'', commonly known as spider flowers, is a genus of about 360 species of evergreen flowering plants in the family Proteaceae. Plants in the genus ''Grevillea'' are shrubs, rarely trees, with the leaves arranged alternately along the branches, the flowers zygomorphic, arranged in racemes at the ends of branchlets, and the fruit a follicle that splits down one side only, releasing one or two seeds. Description Plants in the genus ''Grevillea'' are shrubs, rarely small trees with simple or compound leaves arranged alternately along the branchlets. The flowers are zygomorphic and typically arranged in pairs along a sometimes branched raceme at the ends of branchlets. The flowers are bisexual, usually with four tepals in a single whorl. There are four stamens and the gynoecium has a single carpel. The fruit is a thin-walled follicle that splits down only one side, releasing one or two seeds before the next growing season.

Casuarina Pauper
''Casuarina pauper'' is a tree from the family Casuarinaceae, native to a band across the drier, inland areas of southern Australia (). ''C. pauper'' is known as a poorer, stunted form of the closely related '' Casuarina cristata'' (). Common names include black oak and belah (). Description ''Casuarina pauper'' is a dioecious tree, 5 to 15 metres tall and up to 0.5 metre in diameter (; ). Specimens growing in the open often develop a dense crown, and when growing in dense stands the main stem tends to be straight for more than half the total height (). The foliage is not composed of true leaves but rather of jointed branchlets that function like leaves (). The true leaves are tiny, tooth-like structures protruding from around the top of each joint (). Leaves are strongly waxy, densely and very shortly hairy, with teeth spreading to recurved (). Bark is hard, dark brown to blackish, with a tight scaly appearance (). Sapwood is wide and creamy coloured, heartwood is reddish bro ...

Mallee (habit)
Mallee are trees or shrubs, mainly certain species of eucalypts, which grow with multiple stems springing from an underground lignotuber, usually to a height of no more than . The term is widely used for trees with this growth habit across southern Australia, in the states of Western Australia, South Australia, New South Wales and Victoria, and has given rise to other uses of the term, including the ecosystems where such trees predominate, specific geographic areas within some of the states and as part of various species' names. Etymology The word is thought to originate from the word ''mali'', meaning water, in the Wemba Wemba language, an Aboriginal Australian language of southern New South Wales and Victoria. The word is also used in the closely related Woiwurrung language and other Aboriginal languages of Victoria, South Australia, and southern New South Wales.

Callitris
''Callitris'' is a genus of coniferous trees in the Cupressaceae (cypress family). There are 16 recognized species in the genus, of which 13 are native to Australia and the other three (''C. neocaledonica, C. sulcata'' and ''C. pancheri'') native to New Caledonia. Traditionally, the most widely used common name is cypress-pine, a name shared by some species of the closely related genus '' Actinostrobus''.Eckenwalder, J.E. 2009. ''Conifers of the World: The Complete Reference''. Timber Press. p. 122-124 Description They are small to medium-sized trees or large shrubs, reaching tall (to in ''C. macleayana''). The leaves are evergreen and scale-like. But young seedlings have needle-like leaves; in ''C. macleayana'', needle-like leaves are found mixed with scale leaves throughout the tree's life. The scales are arranged in six rows along the twigs, in alternating whorls of three (often in whorls of four in ''C. macleayana''). The male cones are small ...

Flora
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] |
Cuesta
A cuesta (from Spanish ''cuesta'' "slope") is a hill or ridge with a gentle slope on one side, and a steep slope on the other. In geology the term is more specifically applied to a ridge where a harder sedimentary rock overlies a softer layer, the whole being tilted somewhat from the horizontal. This results in a long and gentle backslope called a dip slope that conforms with the dip of resistant strata, called caprock. Where erosion has exposed the frontslope of this, a steep slope or escarpment occurs. The resulting terrain may be called scarpland. Definition In general usage, a cuesta is a hill or ridge with a gentle slope (backslope) on one side, and a steep slope (frontslope) on the other. The word is from Spanish: "flank or slope of a hill; hill, mount, sloping ground". In geology and geomorphology, cuesta refers specifically to an asymmetric ridge with a long and gentle backslope called a dip slope that conforms with the dip of a resistant stratum or strata, called cap ...

Strike (geology)
Strike and dip is a measurement convention used to describe the orientation, or attitude, of a planar geologic feature. A feature's strike is the azimuth of an imagined horizontal line across the plane, and its dip is the angle of inclination measured downward from horizontal. They are used together to measure and document a structure's characteristics for study or for use on a geologic map. A feature's orientation can also be represented by dip and dip direction, using the azimuth of the dip rather than the strike value. Linear features are similarly measured with trend and plunge, where "trend" is analogous to dip direction and "plunge" is the dip angle. Strike and dip are measured using a compass and a clinometer. A compass is used to measure the feature's strike by holding the compass horizontally against the feature. A clinometer measures the features dip by recording the inclination perpendicular to the strike. These can be done separately, or together using a tool such a ...
