Melastoma Affine
''Melastoma affine'', also known by the common names blue tongue, straits rhododendron or native lassiandra, is a shrub of the family Melastomataceae. Distributed in tropical and sub-tropical forests of India, South-east Asia and Australia, it is a plant of rainforest margins. Bees are the principal pollinators of this species. Taxonomy ''Melastoma affine'' was first described by Scottish botanist David Don in 1823. The taxonomy of the genus ''Melastoma'' is tricky, requiring a complete revision. Early genetics studies were published from 2001, – see also the erratum. through to recently, but a revision based on them has yet to be. In 2001 Karsten Meyer proposed a revision in which this species and other species were subsumed within the species '' Melastoma malabathricum''. In Australia, currently most authorities do not accept this; instead the naturally occurring populations in WA, NT, Qld and northeastern NSW remain recognised as this species ''M. affine'', except by ...

David Don
David Don (21 December 1799 – 15 December 1841) was a Scottish botanist. Biography David Don was born on 21 December 1799 at Doo Hillock, Forfar, Angus, Scotland to Caroline Clementina Stuart, and her husband George Don of Forfar. His older brother was George Don, also a botanist. His father was a curator at the Royal Botanic Garden, Leith Walk, Edinburgh. Don was Professor of Botany at King's College London from 1836 to 1841, and librarian at the Linnean Society of London from 1822 to 1841. He described several of the major conifers discovered in the period, including first descriptions of coast redwood (''Taxodium sempervirens'' D. Don; now ''Sequoia sempervirens'' (D. Don) Endl.), Bristlecone Fir (''Pinus bracteata'' D. Don, now ''Abies bracteata'' (D. Don) A. Poit.), Grand Fir (''Pinus grandis'' Douglas ex D. Don; now ''Abies grandis'' (Douglas ex D.

Leaf Shape
The following terms are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (that is, the leaf blade or 'lamina' is undivided) or compound (that is, the leaf blade is divided into two or more leaflets). The edge of the leaf may be regular or irregular, and may be smooth or have hair, bristles, or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to call leaves on the same tree "ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endangered Flora Of Australia
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melastoma
''Melastoma'' is a genus in the family Melastomataceae. It has over 100 species distributed around Southeast Asia, India, north to Japan, south to Australia and the Pacific Islands. The number of species should probably be reduced according to some sources. Many species have been planted around the world for the aesthetic value of their bright purple flowers. Species in this genus are native to temperate and tropical Asia, Seychelles, Pacific and Australasia. Several have the capacity to become invasive species, in Hawaii and other areas. Decription At least one species contains raphide, sphaeraphides. They were found in abundance in the endophloem and mesophloem, but none occurred in the bark or leaves. Species , ''Plants of the World Online'' (PoWO) accepted the following species. An additional species, ''Melastoma malabituin'', was described in 2020. * ''Melastoma aculeolatum'' Bakh.f. * ''Melastoma affine'' D.Don * ''Melastoma ansowii'' K.M.Wong * ''Melastoma apiense'' ...

Herbal Medicine
Herbal medicine (also called herbalism, phytomedicine or phytotherapy) is the study of pharmacognosy and the use of medicinal plants, which are a basis of traditional medicine. Scientific evidence for the effectiveness of many herbal treatments remains limited, prompting ongoing regulatory evaluation and research into their safety and efficacy. Standards for purity or dosage are generally not provided. The scope of herbal medicine sometimes includes fungal and bee products, as well as minerals, shells and certain animal parts. Paraherbalism is the pseudoscientific use of plant or animal extracts as medicine, relying on unproven beliefs about the safety and effectiveness of minimally processed natural substances. Herbal medicine has been used since at least the Paleolithic era, with written records from ancient Sumer, Egypt, Greece, China, and India documenting its development and application over millennia. Modern herbal medicine is widely used globally—especially in Asia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grass Jelly
Grass jelly, also known as leaf jelly or herbal jelly, is a Gelatin, jelly-like dessert originating in China. It is commonly consumed in East Asia and Southeast Asia. It is created by using Platostoma palustre, Chinese mesona (a member of the mint family) and has a mild, slightly bitter taste. Grass jelly was invented by the Hakka people who historically used the food to alleviate heat stroke after long days working in the field. The dish was introduced to Southeast Asia by the Overseas Chinese, Chinese diaspora. It is served chilled, with other toppings, such as fruit, or in bubble tea or other drinks. Outside Asia, it is sold in Asian supermarkets. Nutritional value Unsweetened grass jelly contains, per 500 grams, 3.5 grams of protein and about 15 grams of carbohydrates, of which 0.5 grams are from dietary fiber. Grass jelly has no fat, vitamins, or minerals. Preparation Grass jelly is made by boiling the aged and slightly oxidized stalks and leaves of ''Platostoma palustre ...

Nomia (bee)
''Nomia'' is a genus of sweat bees in the family Halictidae. Many species have opalescent bands on the metasoma. ''Nomia'' species are moderate-sized bees that nest in the ground. Most species nest solitarily, but some species also nest communally where females share a nest but where there are no queen or worker castes. ''Nomia'' species are found Africa, tropical Asia, Australia, and in North America. There are about 130 species world wide. Alkali bee, ''Nomia'' ''melanderi'' is an important pollinator of alfalfa. They prefer to nest in salty soils. The Walla Walla Valley farmers in Washington State not only sell alfalfa, but some farmers also raise and sell this species of bee. Identification Wings The marginal cell is rounded with the second submarginal cell being shorter than the first and third (three submarginal cells total). The basal vein is not as curved as other members of the family Halictidae. Face & body ''Nomia'' has a rounded face with the eyes melding ...

Xylocopa Bombylans
''Xylocopa bombylans'', the peacock carpenter bee, is a species of carpenter bee found in Australia. It gets its common name by its habit of burrowing into wood. It was originally described by Danish naturalist Johan Christian Fabricius in 1775. Its specific epithet is the Latin ' "like a bumblebee". The name is derived from the Ancient Greek (') "wood-cutter". As its name implies, the peacock carpenter bee is a metallic blue-green or green in colour, although it may even appear purplish from some angles. A large stocky bee, it is often heard by its loud low-pitched buzzing while flying between flowers. The male has white face markings. The bee does have a sting which is potentially painful, although no stings have been recorded. The natural distribution is from the Cape York Peninsula in north Queensland south along the eastern seaboard to the Sydney region (where it overlaps with '' X. aerata''). They can be seen from spring to autumn, commonly feeding at pea flowers of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buzz Pollination
Buzz pollination or sonication is a technique used by some bees, such as solitary bees and bumblebees, to release pollen which is more or less firmly held by the anthers. The anthers of buzz-pollinated plant species are typically tubular, with an opening at only one end, and the pollen inside is smooth-grained and firmly attached. With self-fertile plants such as tomatoes, wind may be sufficient to shake loose the pollen through pores in the anther and accomplish pollination. Visits by bees may also shake loose some pollen, but more efficient pollination of those plants is accomplished by a few insect species who specialize in sonication or buzz pollination. In order to release the pollen, solitary bees are able to grab onto the flower and move their flight muscles rapidly, causing the flower and anthers to vibrate, dislodging pollen. Pollination involving vibrations is called buzz pollination. Honeybees cannot perform buzz pollination. About 9% of the flowers of the world are pri ...

Rain Forest
Rainforests are forests characterized by a closed and continuous tree Canopy (biology), canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforests can be generally classified as tropical rainforests or temperate rainforests, but other types have been described. Estimates vary from 40% to 75% of all biotic community, biotic species being Indigenous (ecology), indigenous to the rainforests. There may be many millions of species of plants, insects and microorganisms still undiscovered in tropical rainforests. Tropical rainforests have been called the "jewels of the Earth" and the "medicine chest (idiom), world's largest pharmacy", because over one quarter of natural medicines have been discovered there. Rainforests as well as endemic rainforest species are rapidly disappearing due to #Deforestation, deforestation, the resulting habitat loss and air pollution, pollution of the atmosphere. Definition Rainforests are cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
