Acacia Brassii
''Acacia brassii'' is a shrub belonging to the genus ''Acacia'' and the subgenus ''Juliflorae'' that is native to north eastern Australia. Description The tree typically grows to a maximum height of . It has dark brown to grey coloured bark that is longitudinally fissured. Its dark red to brown coloured branchlets are glabrous or lightly haired and are flattened towards the apices and have scurfy ridges. Like most species of ''Acacia'' it has phyllodes rather than true leaves. The evergreen, coriaceous and mostly glabrous phyllodes have a lanceolate or narrowly ovate shape and are narrowed at both ends. The phyllodes are flat and sickle shaped with a length of and a width of with three prominent nerves. It blooms between June and July producing golden flowers. The cylindrical flower-spikes have a length of and are covered in golden flower. The waxy, coriaceous-crustaceous seed pods that form after flowering are linear and resemble a string of beads with a length of and have ...

Leslie Pedley
Leslie Pedley (19 May 1930 – 27 November 2018)IPNILeslie Pedley/ref> was an Australian botanist who specialised in the genus ''Acacia''. He is notable for bringing into use the generic name ''Racosperma'', creating a split in the genus, which required some 900 Australian species to be renamed, because the type species of ''Acacia'', ''Acacia nilotica'', now ''Vachellia nilotica'', had a different lineage from the Australian wattles. However, the International Botanical Congress (IBC), held in Melbourne in 2011, ratified its earlier decision to retain the name ''Acacia'' for the Australian species, but to rename the African species. See also: ''Acacia'' and ''Vachellia nilotica'' regarding the dispute, anAPNIfor a brief history of the name, ''Racosperma''. In 2018, Japanese botanists Hiroyoshi Ohashi and Kazuaki K.

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 record ...

Acacia
''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 (by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Glabrousness (botany)
Glabrousness (from the Latin ''glaber'' meaning "bald", "hairless", "shaved", "smooth") is the technical term for a lack of hair, down, setae, trichomes or other such covering. A glabrous surface may be a natural characteristic of all or part of a plant or animal, or be due to loss because of a physical condition, such as alopecia universalis in humans, which causes hair to fall out or not regrow. In botany Glabrousness or otherwise, of leaves, stems, and fruit is a feature commonly mentioned in plant keys; in botany and mycology, a ''glabrous'' morphological feature is one that is smooth and may be glossy. It has no bristles or hair-like structures such as trichomes. In anything like the zoological sense, no plants or fungi have hair or wool, although some structures may resemble such materials. The term "glabrous" strictly applies only to features that lack trichomes at all times. When an organ bears trichomes at first, but loses them with age, the term used is ''glabrescen ...

Phyllode
Phyllodes are modified petioles or leaf stems, which are leaf-like in appearance and function. In some plants, these become flattened and widened, while the leaf itself becomes reduced or vanishes altogether. Thus the phyllode comes to serve the purpose of the leaf. Some important examples are ''Euphorbia royleana'' which are cylindrical and '' Opuntia'' which are flattened. They are common in the genus ''Acacia'', especially the Australian species, at one time put in ''Acacia'' subg. ''Phyllodineae''. Sometimes, especially on younger plants, partially formed phyllodes bearing reduced leaves can be seen. The illustration (to the right) of ''Acacia suaveolens'' from ''Novae Hollandiae plantarum specimen'' shows the juvenile true leaves, together with the developing phyllodes, and the phyllodes of the mature plant. The genus, ''Daviesia'', in the family Fabaceae, is characterised in part by the plants having phyllodes. File:Acacia suaveolens 9064505997 9f14f5f117 o.jpg, ''Acacia ...

Seed Pod
This page provides a glossary of plant morphology. Botanists and other biologists who study plant morphology use a number of different terms to classify and identify plant organs and parts that can be observed using no more than a handheld magnifying lens. This page provides help in understanding the numerous other pages describing plants by their various taxa. The accompanying page—Plant morphology—provides an overview of the science of the external form of plants. There is also an alphabetical list: Glossary of botanical terms. In contrast, this page deals with botanical terms in a systematic manner, with some illustrations, and organized by plant anatomy and function in plant physiology. This glossary primarily includes terms that deal with vascular plants (ferns, gymnosperms and angiosperms), particularly flowering plants (angiosperms). Non-vascular plants (bryophytes), with their different evolutionary background, tend to have separate terminology. Although plant morpholo ...

Western Australian Herbarium
The Western Australian Herbarium is the State Herbarium in Perth, Western Australia. It is part of the State government's Department of Parks and Wildlife, and has responsibility for the description and documentation of the flora of Western Australia. It has the Index Herbariorum code of PERTH. The Hebarium forms part of the Australasian Virtual Herbarium. The Herbarium is linked to the Western Australian 'Regional Herbaria Network' – which links approximately 84 regional community groups which have local reference collections. In 2000, with the Wildflower Society of Western Australia and the Botanic Gardens and Parks Authority it published '' The Western Australian Flora – A Descriptive Catalogue''. History The Herbarium was formed as the amalgamation of three separate government department herbaria: those of the Western Australian Museum, the Department of Agriculture, and the "forest herbarium" maintained by the Conservator of Forests. The first of these was formed by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape York Peninsula
Cape York Peninsula is a large peninsula located in Far North Queensland, Australia. It is the largest unspoiled wilderness in northern Australia.Mittermeier, R.E. et al. (2002). Wilderness: Earth’s last wild places. Mexico City: Agrupación Sierra Madre, S.C. The land is mostly flat and about half of the area is used for grazing cattle. The relatively undisturbed eucalyptus-wooded savannahs, tropical rainforests and other types of habitat are now recognised and preserved for their global environmental significance. Although much of the peninsula remains pristine, with a diverse repertoire of endemic flora and fauna, some of its wildlife may be threatened by industry and overgrazing as well as introduced species and weeds.Mackey, B. G., Nix, H., & Hitchcock, P. (2001). The natural heritage significance of Cape York Peninsula. Retrieved 15 January 2008, froepa.qld.gov.au. The northernmost point of the peninsula is Cape York ().

Melaleuca Viridiflora
''Melaleuca viridiflora'', commonly known as broad-leaved paperbark, is a plant in the myrtle family Myrtaceae, and is native to woodlands, swamps and streams in monsoonal areas of northern Australia and New Guinea. It is usually a small tree with an open canopy, papery bark and spikes of cream, yellow, green or red flowers. Description ''Melaleuca viridiflora'' is a shrub or small tree usually growing to tall, sometimes twice that height, with white, brownish or grey bark and an open canopy. Its leaves are long, wide, thick, broadly elliptic and aromatic. The flowers are cream, yellow, yellow-green or occasionally red and arranged in spikes on the ends of branch which continue to grow after flowering and sometimes also in the upper leaf axils. Each spike contains 8 to 25 groups of flowers in threes and is up to long and in diameter. The petals are long and fall off as the flower matures. There are five bundles of stamens around the flower, each with 6 or 9 stamens although ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Acacia Species
Several Cladistics, cladistic analyses have shown that the genus ''Acacia sensu lato, 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 genus, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
