Acacia Delibrata
''Acacia delibrata'' is a perennial shrub or tree growing to 9m in height, with a distinctive "minni ritchi" bark, flowering from April to June and in October. It is native to tropical Western Australia. It is not listed as being a threatened species. A crude saponin Saponins (Latin ''sapon'', 'soap' + ''-in'', 'one of') are bitter-tasting, usually toxic plant-derived secondary metabolites. They are organic chemicals that become foamy when agitated in water and have high molecular weight. They are present ... solution in water, prepared from the seed pods of a tree believed to be this species, was found to be severely irritant when applied to the eyes of a dog.

Benth
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. His father, Sir Samuel Bentham, a naval architect, was the only brother of Jeremy Bentham to survive into adulthood. His mother, Mary Sophia Bentham, was a botanist and author. Bentham had no formal education but had a remarkable linguistic aptitude. By ...

Australasian Virtual Herbarium
The ''Australasian Virtual Herbarium'' (AVH) is an online resource that allows access to plant specimen data held by various Australian and New Zealand herbaria. It is part of the Atlas of Living Australia (ALA), and was formed by the amalgamation of ''Australia's Virtual Herbarium'' and ''NZ Virtual Herbarium''. As of 12 August 2014, more than five million specimens of the 8 million and upwards specimens available from participating institutions have been databased. Uses This resource is used by academics, students, and anyone interested in research in botany in Australia or New Zealand, since each record tells all that is known about the specimen: where and when it was collected; by whom; its current identification together with the botanist who identified it; and information on habitat and associated species. ALA post processes the original herbarium data, giving further fields with respect to taxonomy and quality of the data. When interrogating individual specimen reco ...

Minni Ritchi
Minni ritchi bark on an acacia in the Pilbara region of Western Australia Minni ritchi bark of ''Eucalyptus crucis'' near Wongan Hills Minni ritchi is a type of reddish-brown bark that continuously peels in small curly flakes, leaving the tree looking like it has a coat of red curly hair. Brooker and Kleinig (1990) formally described it as a bark type in which "the outer rich, red-brown smooth bark splits both longitudinally and horizontally, the free edges rolling back without completely detaching to expose new green bark beneath". A number of species of ''Acacia'' and ''Eucalyptus'' have minni ritchi bark, including: * '' Acacia curranii'' * '' Acacia cyperophylla'' (creekline miniritchie) * '' Acacia delibrata'' * ''Acacia gracillima ''Acacia minniritchi'' is a shrub of the genus ''Acacia'' that is native to the Kimberley region of Western Australia.

Western Australia
Western Australia (WA) is the westernmost state of Australia. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a land area of , and is also the List of country subdivisions by area, second-largest subdivision of any country on Earth. Western Australia has a diverse range of climates, including tropical conditions in the Kimberley (Western Australia), Kimberley, deserts in the interior (including the Great Sandy Desert, Little Sandy Desert, Gibson Desert, and Great Victoria Desert) and a Mediterranean climate on the south-west and southern coastal areas. the state has 2.965 million inhabitants—10.9 percent of the national total. Over 90 percent of the state's population live in the South-West Land Division, south-west corner and around 80 percent live in the state capital Perth, leaving the remainder ...

Threatened Species
A threatened species is any species (including animals, plants and fungi) which is vulnerable to extinction in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of ''critical depensation'', a mathematical measure of biomass related to population growth rate. This quantitative metric is one method of evaluating the degree of endangerment without direct reference to human activity. IUCN definition The International Union for Conservation of Nature (IUCN) is the foremost authority on threatened species, and treats threatened species not as a single category, but as a group of three categories, depending on the degree to which they are threatened: *Vulnerable species *Endangered species *Critically endangered species Less-than-threatened categories are near threatened, least concern, and the no longer assigned category of conservation dependent. Species that have not been evaluated (NE), or do not have sufficient data ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saponin
Saponins (Latin ''sapon'', 'soap' + ''-in'', 'one of') are bitter-tasting, usually toxic plant-derived secondary metabolites. They are organic chemicals that become foamy when agitated in water and have high molecular weight. They are present in a wide range of plant species throughout the bark, leaves, stems, roots and flowers but particularly in soapwort (genus '' Saponaria''), a flowering plant, the soapbark tree ('' Quillaja saponaria''), common corn-cockle ('' Agrostemma githago'' L.), baby's breath ( ''Gypsophila'' spp.) and soybeans ('' Glycine max'' L.). They are used in soaps, medicines (e.g. drug adjuvants), fire extinguishers, dietary supplements, steroid synthesis, and in carbonated beverages (for example, being responsible for maintaining the head on root beer). Saponins are both water and fat soluble, which gives them their useful soap properties. Some examples of these chemicals are glycyrrhizin ( licorice flavoring) and quillaia (alt. quillaja), a bark ext ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Acacia Species
There are 1085 species of ''Acacia'' accepted by Plants of the World Online as at December 2024, with species native to Australia, New Guinea, Southeast Asia, Hawaii and the Mascarene Islands, and introduced to other countries. An older concept of ''Acacia'' included about 1350 species from Australia, Africa, tropical America and Asia, but following decisions made at the 2011 International Botanical Congresses, the name ''Acacia'' was reserved for species found in Australia, New Guinea and Southeast Asia. Some species, previously included in ''Acacia'' and distributed in the Indian Ocean, tropical Asia and tropical Americas, America are now classified under: * ''Vachellia'' 157 species (pantropical) * ''Senegalia'' 220 species (pantropical) * ''Parasenegalia'': 11 species (South America) * ''Pseudosenegalia'': 2 species (Bolivia) * ''Acaciella'' : 15 species (Americas) * ''Mariosousa'': 14 species (Americas) Species list This is a list of species of ''Acacia'' accepted by Pl ...

Acacia
''Acacia'', commonly known as wattles or acacias, is a genus of about of shrubs and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially, it comprised a group of plant species native to Africa, South America, and Australasia, but is now reserved for species mainly from Australia, with others from New Guinea, Southeast Asia, and the Indian Ocean. The genus name is Neo-Latin, borrowed from Koine Greek (), a term used in antiquity to describe a preparation extracted from '' Vachellia nilotica'', the original type species. Several species of ''Acacia'' have been introduced to various parts of the world, and two million hectares of commercial plantations have been established. Description Plants in the genus ''Acacia'' are shrubs or trees with bipinnate leaves, the mature leaves sometimes reduced to phyllodes or rarely absent. There are 2 small stipules at the base of the leaf, but sometimes fall off as the leaf matures. The flowers are borne in spik ...

Trees Of Australia
The flora of Australia comprises a vast assemblage of plant species estimated to over 21,000 vascular and 14,000 non-vascular plants, 250,000 species of fungi and over 3,000 lichens. The flora has strong affinities with the flora of Gondwana, and below the family level has a highly endemic angiosperm flora whose diversity was shaped by the effects of continental drift and climate change since the Cretaceous. Prominent features of the Australian flora are adaptations to aridity and fire which include scleromorphy and serotiny. These adaptations are common in species from the large and well-known families Proteaceae (''Banksia''), Myrtaceae (''Eucalyptus'' - gum trees), and Fabaceae (''Acacia'' - wattle). The arrival of humans around 50,000 years ago and the settlement by Europeans from 1788, has had a significant impact on the flora. The use of fire-stick farming by Aboriginal people led to significant changes in the distribution of plant species over time, and the large-scal ...

Fabales Of Australia
Fabales is 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 Rosales. ...
