Androcalva Pulchella
''Androcalva pulchella'' is a species of flowering plant in the family Malvaceae and is endemic to the south-west of Western Australia. It is a small shrub with egg-shaped, elliptic or oblong leaves, the edges wavy, lobed or toothed, and clusters of two to seven white and deep pink flowers. Description ''Androcalva pulchella'' is a shrub that typically grows to high and wide, its young branches covered with rust-coloured, star-shaped and glandular hairs. Its leaves are egg-shaped, elliptic or oblong, long and wide on a petiole about long with narrowly triangular stipules long at the base. The edges of the leaves are wavy with lobes or coarse teeth. The flowers are arranged in cymes of two to seven on a peduncle long, each flower on a pedicel long, with bracts long at the base. The flowers are about in diameter with 5 white, petal-like sepals with and 5 small white, cup-shaped petals with a deep pink base. There are branched staminodes between each pair of stamens. Flo ...

Nikolai Turczaninow
Nikolai Stepanovich Turczaninow ( ru , Николай Степанович Турчанинов, 1796 in Nikitovka, now in Krasnogvardeysky District, Belgorod Oblast, Russia – 1863 in Kharkov) was a Russian botanist and plant collector who first identified several genera, and many species, of plants. Education and career Born in 1796, Turczaninow attended high school in Kharkov. In 1814, he graduated from Kharkov University, before working as a civil servant for the Ministry of Finance in St. Petersburg. Soon after, in 1825, Turczaninow published his first botanical list. Despite being employed in a different field, he continued his largely self-taught botanical work. In 1828, he was assigned an administrative post in Irkutsk, Siberia. This allowed him to collect in the Lake Baikal area, which is known for its rich biodiversity. A spate of papers followed, and Turczaninow established his own herbarium containing plants from the region. In 1830, he was appointed a Fello ...

Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains '' microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea''). The androecium in va ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malvales Of Australia
The Malvales are an order of flowering plants. As circumscribed by APG II-system, the order includes about 6000 species within 9 families. The order is placed in the eurosids II, which are part of the eudicots. The plants are mostly shrubs and trees; most of its families have a cosmopolitan distribution in the tropics and subtropics, with limited expansion into temperate regions. An interesting distribution occurs in Madagascar, where three endemic families of Malvales (Sphaerosepalaceae, Sarcolaenaceae and Diegodendraceae) occur. Many species of Malvaceae ''sensu lato'' are known for their wood, with that of '' Ochroma'' (balsa) being known for its lightness, and that of ''Tilia'' (lime, linden, or basswood) as a popular wood for carving. Fruit of the cacao tree (''Theobroma cacao'') are used as an ingredient for chocolate. Kola nuts (genus ''Cola'') are notable for their high content of caffeine and, in past, were commonly used for preparing of various cola drinks. Other ...

Avon Wheatbelt
The Avon Wheatbelt is a bioregion in Western Australia. It has an area of . It is considered part of the larger Southwest Australia savanna ecoregion. Geography The Avon Wheatbelt bioregion is mostly a gently undulating landscape with low relief. It lies on the Yilgarn Craton, an ancient block of crystalline rock, which was uplifted in the Tertiary and dissected by rivers. The craton is overlain by laterite deposits, which in places have decomposed into yellow sandplains, particularly on low hills. Steep-sided erosional gullies, known as breakaways, are common.

Wongan Hills
Wongan Hills is a range of low flat-topped hills in the Avon Wheatbelt bioregion of Western Australia. It is located at , in the Shire of Wongan–Ballidu. History The range was first recorded in 1836 by Surveyor General of Western Australia John Septimus Roe. The area was settled by the 1900s (decade), and in 1911 the town of Wongan Hills was established and named after the range. Etymology "Wongan" is derived from the Indigenous Australian name "wangan-katta", "wankan" and "woongan". "Katta" is known to mean "hill", but the meaning of "wongan" is uncertain. It may be related to "kwongan", an indigenous word for sandplain, or "whispering", in which case "wongan katta" would mean "whispering hills". Flora and fauna The hills are biologically significant because they contain the largest remaining single area of natural vegetation in northern parts of the wheatbelt. The hills are home to remnant woodlands of salmon gum, York gum, gimlet (''Eucalyptus salubris''), and silver mal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Green Head, Western Australia
Green Head is a small Australian coastal town in the Shire of Coorow. The town is situated between Geraldton and Perth in the Mid West region of Western Australia along Indian Ocean Drive. Its beaches and lifestyle provide a relaxed holiday atmosphere. It is the home of what was a significant, but now declining, rock lobster industry. History The first Europeans known to visit the Green Head coast were Dutch sailors in the 1600s, sailing to Indonesia for trade. Several Dutch ships were wrecked on the Western Australian reefs, among them the '' Vergulde Draeck'' (Gilt Dragon). Abraham Leeman and crew from the ''Waeckende Boey'', while searching in the ship's small boat for survivors of the ''Vergulde Draeck'', were marooned on Fishermans Island just south of Green Head in 1658. The town was named after the nearby headland, which was originally named in 1875 by Staff-Commander William Edwin Archdeacon R.N., who was in charge of the Admiralty survey of the coast of Wester ...

Mallee Woodlands And Shrublands
Mallee Woodlands and Shrublands is one of 32 List of Major Vegetation Groups in Australia, Major Vegetation Groups defined by the Australian Government Department of the Environment and Energy. Description "Mallee (habit), Mallee" refers to the growth habit of a group of (mainly) eucalypt species that grow to a height of , have many stems arising from a lignotuber and have a leafy canopy that shades 30–70% of the ground. The term is also applied to a vegetation association where these mallee eucalypts grow, on land that is generally flat without hills or tall trees and where the climate is semi-arid.

Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus '' Homo'' and within this genus to the species '' Homo sapiens''. '' Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
