Grewia Insularis
''Grewia insularis '' is a species of flowering plant in the Malvaceae, or mallow family, that is endemic to Christmas Island, an Australian territory in the north-eastern Indian Ocean. Its specific epithet is the Latin for insular, referring to its island location.Flora of Australia Online. Description ''Grewia insularis'' is a shrub or small tree. Its leaves are oblong to ovate, 40–110 mm long. The yellow flowers are usually 1–3 in an umbel, often with several umbels from one leaf-axil. The fruit is purple, often reduced to a subglobose drupe In botany, a drupe (or stone fruit) is a type of fruit in which an outer fleshy part (exocarp, or skin, and mesocarp, or flesh) surrounds a single shell (the ''pip'' (UK), ''pit'' (US), ''stone'', or ''pyrena'') of hardened endocarp with a seed ... about 3 mm long.

Henry Nicholas Ridley
Henry Nicholas Ridley CMG (1911), MA (Oxon), FRS, FLS, F.R.H.S. (10 December 1855 – 24 October 1956) was an English botanist, geologist and naturalist who lived much of his life in Singapore. He was instrumental in promoting rubber trees in the Malay Peninsula that led to a level of rapid deforestation, instrumental in the 1926 Great Flood. For the fervour with which he pursued this work he came to be known as "Mad Ridley". Life Henry Ridley was the second son and third child born to Louisa Pole Stuart and Oliver Matthew Ridley in West Harling in Norfolk, where his father was the Rector. At the age of three his mother died and his father moved to Cobham in Kent. He studied at Tonbridge School and then went to Haileybury where his brother Stuart also studied. At Cobham, he had taken to the idea of collecting insects and he continued this at Haileybury where the school encouraged him to publish a "List of the Mammals and Coleoptera of Haileybury". The two brothers left Ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Umbel
UMBEL (Upper Mapping and Binding Exchange Layer) is a logically organized knowledge graph of 34,000 concepts and entity types that can be used in information science for relating information from disparate sources to one another. It was retired at the end of 2019. UMBEL was first released in July 2008. Version 1.00 was released in February 2011. Its current release is version 1.50. The grounding of this information occurs by common reference to the permanent URIs for the UMBEL concepts; the connections within the UMBEL upper ontology enable concepts from sources at different levels of abstraction or specificity to be logically related. Since UMBEL is an open-source extract of the OpenCyc knowledge base, it can also take advantage of the reasoning capabilities within Cyc. UMBEL has two means to promote the semantic interoperability of information:. It is: * An ontology of about 35,000 reference concepts, designed to provide common mapping points for relating different on ...

Malvales Of Australia
The Malvales are an order of flowering plants. As circumscribed by APG II-system, the order includes about 6000 species within nine families. The order is placed in the eurosids II, which are part of the eudicots. The plants are mostly shrubs and trees; most of its families have a cosmopolitan distribution in the tropics and subtropics, with limited expansion into temperate regions. An interesting distribution occurs in Madagascar, where three endemic families of Malvales (Sphaerosepalaceae, Sarcolaenaceae and Diegodendraceae) occur. Many species of Malvaceae, '' sensu lato'' (in the broad sense), are valued for their wood, with that of '' Ochroma'' (balsa) being known for its lightness, and that of ''Tilia'' (lime, linden, or basswood) as a popular wood for carving. Fruit of the cacao tree (''Theobroma cacao'') are used as an ingredient for chocolate. Kola nuts (genus ''Cola'') are notable for their high caffeine content and were commonly used in the past in preparation of ...

Endemic Flora Of Christmas Island
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are Indigenous (ecology), 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a la ...

Grewia
''Grewia'' is a large flowering plant genus in the mallow family (biology), family Malvaceae, in the expanded sense as proposed by the Angiosperm Phylogeny Group. Formerly, ''Grewia'' was placed in either the family Tiliaceae or the Sparrmanniaceae. However, these were both not monophyletic with respect to other Malvales - as already indicated by the uncertainties surrounding placement of ''Grewia'' and similar genera - and have thus been merged into the Malvaceae. Together with the bulk of the former Sparrmanniaceae, ''Grewia'' is in the subfamily Grewioideae and therein the tribe (biology), tribe Grewieae, of which it is the type genus. The genus was named by Carl Linnaeus, in honor of the botanist Nehemiah Grew (1641-1712) from England. Grew was one of the leading plant anatomists and microscope researchers of his time, and his study of pollen laid the groundwork for modern-day palynology. Ecology and uses Several Lepidoptera caterpillars are found to feed on ''Grewia'' spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Biological Resources Study
Australian Biological Resources Study (ABRS) is a project undertaken by the Parks Australia Division of Australia's Department of Climate Change, Energy, the Environment and Water. Background ABRS was founded in 1973 from the recommendations of a 1972 Senate Select Committee report on Wildlife Conservation. ABRS was first set up as an Interim Council in 1973, followed by the establishment of the Study proper in 1978. The main aim of the Interim Council was to stimulate the study of taxonomy, distribution and ecology of Australia's biological resources via research grants, and for assessing the long term national requirements for taxonomic studies and maintenance of national collections of biological specimens. Research grants A core aim of the ABRS is to provide funding to support research on taxonomy and systematics for Australia's biota. The first grants offered by ABRS were to support the collection and scientific description of Australian plants and animals. Up to $75 ...

Drupe
In botany, a drupe (or stone fruit) is a type of fruit in which an outer fleshy part (exocarp, or skin, and mesocarp, or flesh) surrounds a single shell (the ''pip'' (UK), ''pit'' (US), ''stone'', or ''pyrena'') of hardened endocarp with a seed (''kernel'') inside. Drupes do not split open to release the seed, i.e., they are dehiscence (botany), indehiscent. These fruits usually develop from a single carpel, and mostly from flowers with Superior ovary, superior ovaries (polypyrenous drupes are exceptions). The definitive characteristic of a drupe is that the hard, woody (lignified) stone is derived from the Ovary (botany), ovary wall of the flower. In an aggregate fruit, which is composed of small, individual drupes (such as a raspberry), each individual is termed a drupelet, and may together form an aggregate fruit. Such fruits are often termed ''berries'', although botanists use a Berry (botany), different definition of ''berry''. Other fleshy fruits may have a stony enclosur ...

Fruit
In botany, a fruit is the seed-bearing structure in flowering plants (angiosperms) that is formed from the ovary after flowering. Fruits are the means by which angiosperms disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and other animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; humans, and many other animals, have become dependent on fruits as a source of food. Consequently, fruits account for a substantial fraction of the world's agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings. In common language and culinary usage, ''fruit'' normally means the seed-associated fleshy structures (or produce) of plants that typically are sweet (or sour) and edible in the raw state, such as apples, bananas, grapes, lemons, oranges, and strawberries. In botanical usage, the term ''fruit'' als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flower
Flowers, also known as blooms and blossoms, are the reproductive structures of flowering plants ( angiosperms). Typically, they are structured in four circular levels, called whorls, around the end of a stalk. These whorls include: calyx, modified leaves; corolla, the petals; androecium, the male reproductive unit consisting of stamens and pollen; and gynoecium, the female part, containing style and stigma, which receives the pollen at the tip of the style, and ovary, which contains the ovules. When flowers are arranged in groups, they are known collectively as inflorescences. Floral growth originates at stem tips and is controlled by MADS-box genes. In most plant species flowers are heterosporous, and so can produce sex cells of both sexes. Pollination mediates the transport of pollen to the ovules in the ovaries, to facilitate sexual reproduction. It can occur between different plants, as in cross-pollination, or between flowers on the same plant or even the same f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
