Lysiphyllum Cunninghamii
''Lysiphyllum cunninghamii'' (commonly known as the Kimberley bauhinia or the jigal tree) is a species of plant in the family (biology), family Fabaceae. It is native to northern Australia where it occurs from Western Australia through the Northern Territory to Queensland. Names The specific epithet, ''cunninghamii'', honours Allan Cunningham (botanist), Allan Cunningham, who was the botanist on the third voyage of HMS Mermaid (1817), the Mermaid with Phillip Parker King, and who collected the type specimen of ''Phanera cunninghamii''.Moore, P. 2005. A Guide to Plants of Inland Australia (p. 361), Reed New Holland, Sydney Australia, ''Jigal'' means mother-in-law and refers to the paired leaflets, which turn away from each other, as in Aboriginal customary law where mother-in-law and son-in-law may not face or interact with one another. (See Avoidance speech, and Dixon (1991) for 'mother-in-law' or 'avoidance' language style.) Aboriginal language names Jaminjung, Ngaliwurru pe ...

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. 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 ...

Mangarrayi Language
Mangarrayi (Manggarrai, Mungerry, Ngarrabadji) is an Australian language spoken in the Northern Territory. Its classification is uncertain. Margaret Sharpe originally sought to record the language but turned to the study of Alawa after the station owner where her informants lived denied her access, having tired of the presence of researchers on the property. Speakers The 2016 Australian Bureau of Statistics official census indicates that there are no speakers of Mangarrayi remaining, however elders Sheila Conway and Jessie Roberts are both speakers of Mangarrayi. Conway continues to make an important contribution to language revitalization projects in the Jilkminggan community. Phonology Consonants Vowels Vowels /i, u, e, o/ can have lax allophones of �, ʊ, ɛ, o̞ Numeric system Mangarrayi has a number system that extends only to three. Vocabulary Capell Capell or Capel is a surname. Notable people with the name include: Capell * Arthur Capell, 1st Baron C ...

Loam
Loam (in geology and soil science) is soil composed mostly of sand (particle size > ), silt (particle size > ), and a smaller amount of clay (particle size < ). By weight, its mineral composition is about 40–40–20% concentration of sand–silt–clay, respectively. These proportions can vary to a degree, however, and result in different types of loam soils: sandy loam, silty loam, clay loam, sandy clay loam, silty clay loam, and loam. In the USDA, United States Department of Agriculture, soil texture, textural classification triangle, the only soil that is not predominantly sand, silt, or clay is called "loam". Loam soils generally contain more nutrients, moisture, and humus than sandy soils, have better drainage and infiltration of water and air than silt- and clay-rich soils, and are easier to tillage, till than clay soils. In fact, the primary definition of loam in most dictionaries is soils containing hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sand
Sand is a granular material composed of finely divided mineral particles. Sand has various compositions but is usually defined by its grain size. Sand grains are smaller than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass. The composition of sand varies, depending on the local rock sources and conditions, but the most common constituent of sand in inland continental settings and non-tropical coastal settings is silica (silicon dioxide, or SiO2), usually in the form of quartz. Calcium carbonate is the second most common type of sand. One such example of this is aragonite, which has been created over the past 500million years by various forms of life, such as coral and shellfish. It is the primary form of sand apparent in areas where reefs have dominated the ecosystem for millions of years, as in the Caribbean. Somewhat more rarely, sand may be composed ...

Alluvium
Alluvium (, ) is loose clay, silt, sand, or gravel that has been deposited by running water in a stream bed, on a floodplain, in an alluvial fan or beach, or in similar settings. Alluvium is also sometimes called alluvial deposit. Alluvium is typically geologically young and is not Consolidation (geology), consolidated into solid rock. Sediments deposited underwater, in seas, estuaries, lakes, or ponds, are not described as alluvium. Floodplain alluvium can be highly fertile, and supported some of the earliest human civilizations. Definitions The present Scientific consensus, consensus is that "alluvium" refers to loose sediments of all types deposited by running water in floodplains or in alluvial fans or related landforms. However, the meaning of the term has varied considerably since it was first defined in the French dictionary of Antoine Furetière, posthumously published in 1690. Drawing upon concepts from Roman law, Furetière defined ''alluvion'' (the French term for al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Native Bees
Australian native bees are a group of bees that play a crucial role in the pollination of Flora of Australia, native plants. There are over 1,700 species of native bees in Australia, ranging from small solitary bees to the social stingless bees. Native bees are important for native ecosystems, providing pollination services to native plants, and hold value for Agriculture in Australia, Australian agriculture. Sting or no sting, solitary vs social Eleven species, of these social native bees, are in two genera, ''Tetragonula'' and ''Austroplebeia'', and have no sting. The stings of most Australian native species of bee will cause relatively minor discomfort to most people and are, "not as painful as those of a bull ant or paper wasp and last only a few minutes". However, they may sting more than once, and can cause an Anaphylaxis, allergic reaction—increasing effect associated with repeated exposure to the antigen. Honey The native species of bee in Australia are not tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Honeyeater
The honeyeaters are a large and diverse family, Meliphagidae, of small to medium-sized birds. The family includes the Australian chats, myzomelas, friarbirds, wattlebirds, miners and melidectes. They are most common in Australia and New Guinea, and found also in New Zealand, the Pacific islands as far east as Samoa and Tonga, and the islands to the north and west of New Guinea known as Wallacea. Bali, on the other side of the Wallace Line, has a single species. In total, there are 186 species in 55 genera, roughly half of them native to Australia, many of the remainder occupying New Guinea. With their closest relatives, the Maluridae (Australian fairy-wrens), Pardalotidae (pardalotes), and Acanthizidae (thornbills, Australian warblers, scrubwrens, etc.), they comprise the superfamily Meliphagoidea and originated early in the evolutionary history of the oscine passerine radiation. Although honeyeaters look and behave very much like other nectar-feeding passerines aroun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bark (botany)
Bark is the outermost layer of Plant stem, stems and roots of woody plants. Plants with bark include trees, woody vines, and shrubs. Bark refers to all the Tissue (biology), tissues outside the vascular cambium and is a nontechnical term. It overlays the wood and consists of the inner bark and the outer bark. The inner bark, which in older Plant stem, stems is living tissue, includes the innermost layer of the periderm. The outer bark on older stems includes the dead tissue on the surface of the stems, along with parts of the outermost periderm and all the tissues on the outer side of the periderm. The outer bark on trees which lies external to the living periderm is also called the Glossary of botanical terms#rhytidome, rhytidome. Products derived from bark include bark shingle siding and wall coverings, spices, and other flavorings, tanbark for tannin, resin, latex, medicines, poisons, various hallucinogenic chemicals, and Cork (material), cork. Bark has been used to make clot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tessellation
A tessellation or tiling is the covering of a surface, often a plane, using one or more geometric shapes, called ''tiles'', with no overlaps and no gaps. In mathematics, tessellation can be generalized to higher dimensions and a variety of geometries. A periodic tiling has a repeating pattern. Some special kinds include '' regular tilings'' with regular polygonal tiles all of the same shape, and '' semiregular tilings'' with regular tiles of more than one shape and with every corner identically arranged. The patterns formed by periodic tilings can be categorized into 17 wallpaper groups. A tiling that lacks a repeating pattern is called "non-periodic". An '' aperiodic tiling'' uses a small set of tile shapes that cannot form a repeating pattern (an aperiodic set of prototiles). A '' tessellation of space'', also known as a space filling or honeycomb, can be defined in the geometry of higher dimensions. A real physical tessellation is a tiling made of materials such as ...

Tree
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, e.g., including only woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller palms, tree ferns, bananas, and bamboos. Trees are not a monophyletic taxonomic group but consist of a wide variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some trees reaching several thousand years old. Trees evolved around 400 million years ago, and it is estimated that there are around three trillion mature trees in the world currently. A tree typically has many secondary branches supported cle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shrub
A shrub or bush is a small to medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple Plant stem, stems and shorter height, less than tall. Small shrubs, less than tall are sometimes termed as subshrubs. Many botany, botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead. Some define a shrub as less than and a tree as over 6 m. Others use as the cutoff point for classification. Many trees do not reach this mature height because of hostile, less than ideal growing conditions, and resemble shrub-sized plants. Others in such species have the potential to grow taller in ideal conditions. For longevity, most shrubs are classified between Perennial plant, perennials and trees. Some only last about five years in good conditions. Others, usually larger and more woody, live beyond ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wagiman
The Wagiman, also spelt Wagoman, Wagaman, Wogeman, and other variants, are an Aboriginal Australian people of the Northern Territory. Language The Wagiman language is a language isolate. It has been contrasted for its comparative roughness to the smooth, euphonious sound of Marrithiel spoken down country by the Marrithiyal people The Marrithiyal, also written Marrithiel, are an Aboriginal Australian people whose traditional territory lay south of Darwin from Litchfield National Park and extend to the Daly River in the Northern Territory. They are also known as the Berr .... Country The Wagiman had, in Tindale's estimation, approximately of territory in the area southwest of the Daly River, and in the area of Dorisvale, and from Bamboo Creek northwards as far as Douglas Homestead. Their frontier to the west, west of Oooloo, lay on the Daly River Crossing close to Mount Nancar, a place where they were accustomed to meet up with the neighbouring tribes, the Kamor and ...
