Acacia Glaucoptera
''Acacia glaucoptera'', commonly known as flat wattle or clay wattle, is a species of ''Acacia'' which is endemic to the south-west of Western Australia. Description It is a spreading or erect shrub which ranges in height from and up to in width. It produces yellow, globular flowers between late winter and early summer. It has glabrous straight to slightly flexuose branchlets. Phyllodes are continuous with the branchlets, forming opposite wings with each one extending to the one underneath. Each one is mostly in length and wide. The free portion of phyllode usually . The rudimentary inflorescences rudimentary with globular flower heads that have a diameter of containing 30 to 80 golden flowers. After flowering black, glabrous, twisted and coiled seed pods are formed that are up to long and wide. The seeds are longitudinally arranged in the pods. They are oblong in shape with a length of .

George Bentham
George Bentham (22 September 1800 – 10 September 1884) was an English botanist, described by the weed botanist Duane Isely as "the premier systematic botanist of the nineteenth century". Born into a distinguished family, he initially studied law, but had a fascination with botany from an early age, which he soon pursued, becoming president of the Linnaean Society in 1861, and a fellow of the Royal Society in 1862. He was the author of a number of important botanical works, particularly flora. He is best known for his taxonomic classification of plants in collaboration with Joseph Dalton Hooker, his ''Genera Plantarum'' (1862–1883). He died in London in 1884. Life Bentham was born in Stoke, Plymouth, on 22 September 1800.Jean-Jacques Amigo, « Bentham (George) », in Nouveau Dictionnaire de biographies roussillonnaises, vol. 3 Sciences de la Vie et de la Terre, Perpignan, Publications de l'olivier, 2017, 915 p.

Acacia Merrallii
''Acacia merrallii'', commonly known as Merrall's wattle, is a shrub belonging to the genus ''Acacia'' and the subgenus ''Phyllodineae'' that is endemic to south western and southern Australia. Description The shrub typically grows to a height of with a width and can have a dense, rounded or spreading habit. The branchlets are often covered in minutely fine, straight or barely curved hairs. Like most species of ''Acacia'' it has phyllodes rather than true leaves. The thick, smooth, grey-green phyllodes have an obliquely obovate to oblong-elliptic shape and is occasionally ovate. The phyllodes have a length of and a width of and are mostly slightly undulate with an obscure midrib and prominent margins. It blooms from August to October and produces yellow flowers. The rudimentary inflorescences are found on one to three headed racemes with a length of up to . The spherical flower-heads have a diameter of and contain 22 to 35 golden coloured flowers.

Fabales Of Australia
The Fabales are an order of flowering plants included in the rosid group of the eudicots in the Angiosperm Phylogeny Group II classification system. In the APG II circumscription, this order includes the families Fabaceae or legumes (including the subfamilies Caesalpinioideae, Mimosoideae, and Faboideae), Quillajaceae, Polygalaceae or milkworts (including the families Diclidantheraceae, Moutabeaceae, and Xanthophyllaceae), and Surianaceae. Under the Cronquist system and some other plant classification systems, the order Fabales contains only the family Fabaceae. In the classification system of Dahlgren the Fabales were in the superorder Fabiflorae (also called Fabanae) with three families corresponding to the subfamilies of Fabaceae in APG II. The other families treated in the Fabales by the APG II classification were placed in separate orders by Cronquist, the Polygalaceae within its own order, the Polygalales, and the Quillajaceae and Surianaceae within the Rosa ...

Acacias Of Western Australia
''Acacia'', commonly known as the wattles or acacias, is a large genus of shrubs and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially, it comprised a group of plant species native to Africa and Australasia. The genus name is New Latin, borrowed from the Greek (), a term used by Dioscorides for a preparation extracted from the leaves and fruit pods of '' Vachellia nilotica'', the original type of the genus. In his ''Pinax'' (1623), Gaspard Bauhin mentioned the Greek from Dioscorides as the origin of the Latin name. In the early 2000s it had become evident that the genus as it stood was not monophyletic and that several divergent lineages needed to be placed in separate genera. It turned out that one lineage comprising over 900 species mainly native to Australia, New Guinea, and Indonesia was not closely related to the much smaller group of African lineage that contained ''A. nilotica''—the type species. This meant that the Australasian lineage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Acacia Species
Several cladistic analyses have shown that the genus ''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 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 as the genus ''Vachellia''.

Cladode
Phylloclades and cladodes are flattened, photosynthetic shoots, which are usually considered to be modified branches. The two terms are used either differently or interchangeably by different authors. '' Phyllocladus'', a genus of conifer, is named after these structures. Phylloclades/cladodes have been identified in fossils dating from as early as the Permian. Definition and morphology The term "phylloclade" is from the New Latin ''phyllocladium'', itself derived from Greek ''phyllo'', leaf, and ''klados'', branch. Definitions of the terms "phylloclade" and "cladode" vary. All agree that they are flattened structures that are photosynthetic and resemble leaf-like branches. In one definition, phylloclades are a subset of cladodes, namely those that greatly resemble or perform the function of leaves, as in Butcher's broom (''Ruscus aculeatus'') as well as '' Phyllanthus'' and some ''Asparagus Asparagus, or garden asparagus, folk name sparrow grass, scientific name ''Aspa ...

Laterite
Laterite is both a soil and a rock type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock, usually when there are conditions of high temperatures and heavy rainfall with alternate wet and dry periods. Tropical weathering (''laterization'') is a prolonged process of chemical weathering which produces a wide variety in the thickness, grade, chemistry and ore mineralogy of the resulting soils. The majority of the land area containing laterites is between the tropics of Tropic of Cancer, Cancer and Tropic of Capricorn, Capricorn. Laterite has commonly been referred to as a soil type as well as being a rock type. This and further variation in the modes of conceptualizing about laterite (e.g. also as a complete weathering profile or theory about weathering) has led to c ...

Esperance, Western Australia
Esperance is a town in the Goldfields–Esperance region of Western Australia, on the Southern Ocean coastline approximately east-southeast of the state capital, Perth. The urban population of Esperance was 12,145 at June 2018. Its major industries are tourism, agriculture, and fishing. History European history of the region dates back to 1627 when the Dutch vessel ''Gulden Zeepaert'', skippered by François Thijssen, passed through waters off the Esperance coast and continued across the Great Australian Bight. French explorers are credited with making the first landfall near the present day town, naming it and other local landmarks while sheltering from a storm in this area in 1792. The town itself was named after a French ship, the ''Espérance'', commanded by Jean-Michel Huon de Kermadec. fr , Espérance , label=none is French for "hope".
