Hassell National Park
Hassell National Park is a national park in the Great Southern region of Western Australia, southeast of Perth and north east of Albany. Named after John Hassell, a retired sea captain, who was responsible for opening up extensive areas in the south of the state during the 1850s as he extended his pastoral leases east from Frankland as far as Jerramungup. The park straddles the South Coast Highway between Manypeaks and Wellstead. The site is regarded as an important ecological area as a result of it being a largely intact vegetation and wildlife corridor that serves to link the Mount Manypeaks and Waychinicup areas with the Cheynes Baech and Pallinup areas. The park has no entry fee and has no facilities provided for visitors. A population of the very rare Brown's Banksia, composed of 100 to 200 plants, can be found within the confines of the park.

Plantae Preissianae
''Plantae preissianae sive enumeratio plantarum quas in australasia occidentali et meridionali-occidentali annis 1838-1841 collegit Ludovicus Preiss'', more commonly known as ''Plantae preissianae'', is a book written by Johann Georg Christian Lehmann and Ludwig Preiss. Written in Latin, it is composed of two volumes and was first published by Sumptibus Meissneri in Hamburg between 1844 and 1847. The two volumes were published in six separate parts. The books detail the plants collected by Ludwig Preiss, James Drummond, Thomas Livingstone Mitchell and Johann Lhotsky in Western Australia. The books are regarded as one of the earliest and most important contributions to the study of the flora of Western Australia. Priess amassed a collection of over 2,700 species of plants while in Western Australia from 1838 to 1842 when he returned to Germany. As a result of Priess' samples and notes Lehmann and his team of botanists, Stephan Endlicher, Christian Gottfried Daniel Nees von Esen ...

Rosids Of Western Australia
The rosids are members of a large clade (monophyletic group) of flowering plants, containing about 70,000 species, more than a quarter of all angiosperms. The clade is divided into 16 to 20 orders, depending upon circumscription and classification. These orders, in turn, together comprise about 140 families. Fossil rosids are known from the Cretaceous period. Molecular clock estimates indicate that the rosids originated in the Aptian or Albian stages of the Cretaceous, between 125 and 99.6 million years ago. Today's forests are highly dominated by rosid species, which in turn helped with diversification in many other living lineages. Additionally, rosid herbs and shrubs are also a significant part of arctic/alpine, temperate floras, aquatics, desert plants, and parasites. Name The name is based upon the name "Rosidae", which had usually been understood to be a subclass. In 1967, Armen Takhtajan showed that the correct basis for the name "Rosidae" is a description of a group ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daviesia
''Daviesia'', commonly known as bitter-peas, is a genus of about 130 species of flowering plants in the family Fabaceae, and is endemic to Australia. Plants in the genus ''Daviesia'' are shrubs or small trees with leaves modified as phyllodes or reduced to scales. The flowers are arranged singly or in groups, usually in leaf axils, the sepals joined at the base with five teeth, the petals usually yellowish with reddish markings and the fruit a pod. Description Plants in the genus ''Daviesia'' are shrubs or small trees with their leaves modified as phyllodes that are often sharply-pointed, or have leaves reduced to scales with the stems modified as cladodes. The flowers are usually arranged in leaf axils, either singly or in clusters or racemes with bracts sometimes present on the peduncles, pedicels or flowering stems.

Jarrah Forest
Jarrah forest is tall open forest in which the dominant overstory tree is ''Eucalyptus marginata'' (jarrah). The ecosystem occurs only in the Southwest Botanical Province of Western Australia. It is most common in the biogeographic region named in consequence Jarrah Forest. Most jarrah forest contains at least one other co-dominant overstory tree; association with ''Corymbia calophylla'' is especially common, and results in which is sometimes referred to as jarrah-marri forest. Considerable amount of research delineates northern, central and southern jarrah forestStrelein, G. J. (1988) ''Site classification in the Southern jarrah forest of Western Australia'' Como, W.A.

Esperance Plains
Esperance Plains, also known as Eyre Botanical District, is a biogeographic region in southern Western Australia on the south coast between the Avon Wheatbelt and Hampton bioregions, and bordered to the north by the Mallee region. It is a plain punctuated by granite and quartz outcrops and ranges, with a semi-arid Mediterranean climate and vegetation consisting mostly of mallee-heath and proteaceous scrub. About half of the region has been cleared for intensive agriculture. Recognised as a bioregion under the Interim Biogeographic Regionalisation for Australia (IBRA), it was first defined by John Stanley Beard in 1980. Geography and geology The Esperance Plains may be roughly approximated as the land within of the coast between Albany and Point Culver on the south coast of Western Australia. It has an area of about , making it about 9% of the South West Province, 1% of the state, and 0.3% of Australia. It is bounded to the north by the Mallee region, and to the west by ...

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.

Stirling Range
The Stirling Range or Koikyennuruff is a range of mountains and hills in the Great Southern region of Western Australia, south-east of Perth. It is over wide from west to east, stretching from the highway between Mount Barker and Cranbrook eastward past Gnowangerup. The Stirling Range is protected by the Stirling Range National Park, which was gazetted in 1913, and has an area of . Environment Geology The mountains are formed of metamorphic rock derived from quartz sandstones and shales deposited during the Paleoproterozoic Era, between 2,016 and 1,215 million years ago (based on U-Th-Pb isotope geochronology of monazite crystals). The sediments were subsequently metamorphosed 1,215 million years ago, and later folded during reactivation of basement structures recording lateral displacements between Antarctica and Australia. Despite the relative youth of the mountains, the soils remain very poor, creating the species-rich heathland flora. Climate As the only ver ...

Mallee Woodlands And Shrublands
Mallee Woodlands and Shrublands is one of 32 Major Vegetation Groups defined by the Australian Government Department of the Environment and Energy. Description " 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. Of the 32 Major Vegetation Groups classified under the National Vegetation Information System, "Mallee Woodlands and Shrublands" (MVG14): * are semi-arid areas dominated by mallee eucalypts; * may also have co-dominant species of '' Callitris'', '' Melaleuca'', ''Acacia'' and ''Hakea''; * have an open tree or shrub layer with more than 10% foliage cover and more than 20% crown cover, distinguishing MVG 14 from "Mallee Open Woodland" (MVG14 ...

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 credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Georg Christian Lehmann
Johann Georg Christian Lehmann (25 February 1792 – 12 February 1860) was a German botanist. Born at Haselau, near Uetersen, Holstein, Lehmann studied medicine in Copenhagen and Göttingen, obtained a doctorate in medicine in 1813 and a doctorate in philosophy from the University of Jena in 1814. He spent the rest of his life as professor of physics and natural sciences, and head librarian, at the '' Gymnasium Academicum'' in Hamburg. A prolific monographist of apparently quarrelsome character, he was a member of 26 learned societies and the founder of the Hamburg Botanical Garden (, now the Alter Botanischer Garten Hamburg). Lehmann died at Hamburg in 1860. Some of Lehmann's later illustrations were executed by the German entomologist Johann Wilhelm Meigen Johann Wilhelm Meigen (3 May 1764 – 11 July 1845) was a German entomologist famous for his pioneering work on Diptera. Life Early years Meigen was born in Solingen, the fifth of eight children of Johann Clemens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
