Bruce Maslin
Bruce Roger Maslin (born 3 May 1946) is an Australian botanist, known for his work on ''Acacia'' taxonomy. Born in Bridgetown, Western Australia, Bridgetown, Western Australia, he obtained an honours degree in botany from the University of Western Australia in 1967, then took up an appointment as a botanist with the Western Australian Herbarium. The following year he was conscription, conscripted to serve in the Vietnam War; he gave three years in National Service, serving in Vietnam in 1969.

Pilbara
The Pilbara () is a large, dry, sparsely populated regions of Western Australia, region in the north of Western Australia. It is known for its Indigenous Australians, Aboriginal people; wealth disparity; its ancient landscapes; the prevailing red earth; and its vast mineral deposits, in particular iron ore. It is also a global biodiversity hotspot for subterranean fauna. Definitions of the Pilbara region At least two important but differing definitions of "the Pilbara" region exist. Administratively it is one of the nine regions of Western Australia defined by the ''Regional Development Commissions Act 1993''; the term also refers to the Pilbara shrublands bioregion (which differs in extent) under the Interim Biogeographic Regionalisation for Australia (IBRA). Geography The Pilbara region, as defined by the Regional Development Commissions Act 1993 and administered for economic development purposes by the Pilbara Development Commission, has an estimated population of 61,68 ...

Acacias Of Western Australia
''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 ...

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 ...

Calcrete
Caliche () is a soil accumulation of soluble calcium carbonate at depth, where it precipitates and binds other materials—such as gravel, sand, clay, and silt. It occurs worldwide, in aridisol and mollisol soil orders—generally in arid or semiarid regions, including in central and western Australia, in the Kalahari Desert, in the High Plains of the western United States, in the Sonoran Desert, Chihuahuan Desert and Mojave Desert of North America, and in eastern Saudi Arabia at Al-Hasa. Caliche is also known as calcrete or kankar (in India). It belongs to the duricrusts. The term is borrowed from Spanish and is originally from the Latin word , meaning lime. Caliche is generally light-colored but can range from white to light pink to reddish-brown, depending on the minerals present. Caliche is a mark of older landscapes. It generally occurs on or very near the surface. Where caliche layers originate at some depth from the soil surface, intact landscapes and buried landsca ...

Newman, Western Australia
Newman, originally named Mount Newman until 1981, is a town in the Pilbara region of Western Australia. It is located about north of Perth, and north of the Tropic of Capricorn. It can be reached by the Great Northern Highway. Newman is a modern mining town, with homes contrasting with the surrounding reddish desert. As of the , Newman had a population of 6,456.

Pty Ltd (a subsidiary of BHP) in 1966 as a company town to support the development of iron ore deposits at nearby Mount Whaleback mine, Mount Whaleback. The town takes its name from nearby Mount Newman, named in honour of government surveyor Aubrey Woodward Newman (son of Edward Newman (Australian politician), Edward Newman who also died young) who died of typhoid aged 28 at Cue, Western Australia, Cue on 24 May 1896, while on an expedition from Nannine to t ...

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 morpholog ...

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 ...

Inflorescence
In botany, an inflorescence is a group or cluster of flowers arranged on a plant's Plant stem, stem that is composed of a main branch or a system of branches. An inflorescence is categorized on the basis of the arrangement of flowers on a main axis (Peduncle (botany), peduncle) and by the timing of its flowering (determinate and indeterminate). Morphology (biology), Morphologically, an inflorescence is the modified part of the Shoot (botany), shoot of spermatophyte, seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internode (botany), internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. General characteristics Inflorescences are described by many different charact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
