Commelina Cyanea
''Commelina cyanea'', commonly known as scurvy weed, is a perennial prostrate herb of the family Commelinaceae native to moist forests and woodlands of eastern Australia, Lord Howe Island and Norfolk Island. The blue flowers appear over the warmer months and are pollinated by bees and flies. Taxonomy ''Commelina cyanea'' was one of the many species initially described by the botanist Robert Brown in his 1810 work ''Prodromus Florae Novae Hollandiae et Insulae Van Diemen'' and still bears its original name. The genus name ''Commelina'' was chosen based on the Asiatic dayflower. Linnaeus picked the name in honour of the Dutch botanists Jan and Caspar Commelijn, using the two large showy petals of ''Commelina communis'' to symbolise them. The specific name is the Latin adjective ''cyaneus'', meaning "blue". As well as scurvy weed, alternative common names include (native) wandering Jew, forget-me-not, and creeping Christian.

Robert Brown (botanist, Born 1773)
Robert Brown (21 December 1773 – 10 June 1858) was a Scottish botanist and paleobotanist who made important contributions to botany largely through his pioneering use of the microscope. His contributions include one of the earliest detailed descriptions of the cell nucleus and cytoplasmic streaming; the observation of Brownian motion; early work on plant pollination and fertilisation, including being the first to recognise the fundamental difference between gymnosperms and angiosperms; and some of the earliest studies in palynology. He also made numerous contributions to plant taxonomy, notably erecting a number of plant families that are still accepted today; and numerous Australian plant genera and species, the fruit of his exploration of that continent with Matthew Flinders. Early life Robert Brown was born in Montrose on 21 December 1773, in a house that existed on the site where Montrose Library currently stands. He was the son of James Brown, a minister in the ...

Commelinales Of Australia
Commelinales is an order of flowering plants. It comprises five families: Commelinaceae, Haemodoraceae, Hanguanaceae, Philydraceae, and Pontederiaceae. All the families combined contain over 885 species in about 70 Genus, genera; the majority of species are in the Commelinaceae. Plants in the order share a number of Synapomorphy, synapomorphies that tie them together, such as a lack of Mycorrhiza, mycorrhizal associations and tapetum (botany), tapetal raphides. Estimates differ as to when the Commelinales evolved, but most suggest an origin and diversification sometime during the mid- to late Cretaceous. Depending on the methods used, studies suggest a range of origin between 123 and 73 million years, with diversification occurring within the group 110 to 66 million years ago. The order's closest relatives are in the Zingiberales, which includes ginger, bananas, cardamom, and others.Stevens, P. F. (2001 onwards). Angiosperm Phylogeny Website. Version 9, November 2011.

Bushfood
Bush tucker, also called bush food, is any food native to Australia and used as sustenance by Indigenous Australians, the Aboriginal and Torres Strait Islander peoples, but it can also describe any native flora or fauna used for culinary or medicinal purposes, regardless of the continent or culture. Animal native foods include kangaroo, emu, witchetty grubs and crocodile, and plant foods include fruits such as quandong, kutjera, spices such as lemon myrtle and vegetables such as warrigal greens and various native yams. Traditional Indigenous Australians' use of bushfoods has been severely affected by the settlement of Australia in 1788 and subsequent settlement by non-Indigenous peoples. The introduction of non-native foods, together with the loss of traditional lands, resulting in reduced access to native foods by Aboriginal people, and destruction of native habitat for agriculture, has accentuated the reduction in use. Since the 1970s, there has been recognition of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commelina
''Commelina'' is a genus of approximately 170 species commonly called dayflowers due to the short lives of their flowers. They are less often known as widow's tears. It is by far the largest genus of its family, Commelinaceae. The Swedish taxonomist Carl Linnaeus of the 18th century named the genus after the two Dutch botanists Jan Commelijn and his nephew Caspar, each representing one of the showy petals of ''Commelina communis''. The dayflowers are herbs that may be either perennial or annual. They are characterised by their zygomorphic flowers and by the involucral bracts called spathes that surround the flower stalks. These spathes are often filled with a mucilaginous liquid. Each spathe houses either one or two scorpioid cymes, with the upper cyme being either vestigial or bearing from one to several typically male flowers, and the lower cyme bearing several flowers. All members of the genus have alternate leaves. The Asiatic dayflower (''Commelina communis'') is probably t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tradescantia Fluminensis
''Tradescantia fluminensis'' is a species of spiderwort native to South America. It is one of several plants known by the common name wandering Jew, but now also commonly called wandering trad. It is also known as small-leaf spiderwort, river spiderwort, inch plant, Speedy Henry, and wandering willie. The genus is named after the English naturalists and explorers John Tradescant the Elder (c. 1570s – 1638) and John Tradescant the Younger (1608–1662). Description ''Tradescantia fluminensis'' is a perennial ground cover that spreads along the ground with soft, hairless stems and leaves. The fleshy stems root at any node that is on the surface. The plant has oval, dark-green leaves with pointed tips that are shiny, smooth and slightly fleshy about long. The white flowers are terminal, sometimes opposite a leaf, and are on a 1.5 cm long stem. The flowers have three petals and approx. in diameter. The sepals are 5–7 mm in size. The three white petals are 8–9&nbs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scurvy
Scurvy is a disease resulting from a lack of vitamin C (ascorbic acid). Early symptoms of deficiency include weakness, feeling tired and sore arms and legs. Without treatment, decreased red blood cells, gum disease, changes to hair, and bleeding from the skin may occur. As scurvy worsens there can be poor wound healing, personality changes, and finally death from infection or bleeding. It takes at least a month of little to no vitamin C in the diet before symptoms occur. In modern times, scurvy occurs most commonly in people with mental disorders, unusual eating habits, alcoholism, and older people who live alone. Other risk factors include intestinal malabsorption and dialysis. While many animals produce their own vitamin C, humans and a few others do not. Vitamin C is required to make the building blocks for collagen. Diagnosis is typically based on physical signs, X-rays, and improvement after treatment. Treatment is with vitamin C supplements taken by mouth. Improvemen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syritta
''Syritta'' is a genus of hoverflies, family Syrphidae. The genus probably originated in the Afrotropical region. 13 of the 18 recognized species groups are found south of the Sahara. 15 species inhabit the Oriental and Australian-Pacific regions, and only six species are described from the Palearctic region. The two species that occur in North America North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Car ... as far south as Mexico, ''S. flaviventris'' and ''S. pipiens'', were probably introduced by humans.

Colletidae
The Colletidae are a family of bees, and are often referred to collectively as plasterer bees or polyester bees, due to the method of smoothing the walls of their nest cells with secretions applied with their mouthparts; these secretions dry into a cellophane-like lining. C. D. Michener (2007) ''The Bees of the World'', 2nd Edition, pg. 133, Johns Hopkins University Press. The five subfamilies, 54 genera, and over 2000 species are all (with the known exception of but one species, '' Amphylaeus morosus'') evidently solitary, though many nest in aggregations. Two of the subfamilies, Euryglossinae and Hylaeinae, lack the external pollen-carrying apparatus (the scopa) that otherwise characterizes most bees, and instead carry the pollen in their crops. These groups, and most genera in this family, have liquid or semiliquid pollen masses on which the larvae develop. They can be found all over the world, but the most species live in South America and Australia. Over 50% of all bee spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Halictidae
Halictidae is the second-largest family of bees (clade Anthophila) with nearly 4,500 species. Halictid species are an extremely diverse group that can vary greatly in appearance. These bees occur all over the world and are found on every continent except Antarctica. Usually dark-colored (frequently brown or black) and often metallic, halictids are found in various sizes, colors and patterns. Several species are all or partly green and a few are red, purple, or blue. A number of them have yellow markings, especially the males, which commonly have yellow faces, a pattern widespread among the various families of bees. The family is one of many with short tongues and is best distinguished by the arcuate (strongly curved) basal vein found on the wing. Females in this family tend to be larger than the males. They are commonly referred to as "sweat bees" (especially the smaller species), as they are often attracted to perspiration. Ecology Most halictids nest in the ground, often in ha ...

Amegilla Pulchra
''Amegilla'' is a large genus of bees in the tribe Anthophorini. Several species have blue metallic bands on the abdomen, and are referred to as "blue-banded bees" and "digger bees". One of their names in english, "digger bees" is given to them because they dig up a hole in dry ground and make it their nest. The genus occurs all around the world but very few live above 45° North. Amegilla are associated with arid and subarid biomes, matorrals, steppes, sub-deserts and deserts. All of Amegilla are solitary species. They are also very fast, agid flyers, and because of this, some taxa are close to imposible to catch. Selected species * '' Amegilla bombiformis'' ( Smith, 1854) * ''Amegilla calens'' ( Lepeletier, 1841) * '' Amegilla canifrons'' (Smith, 1854) * '' Amegilla confusa'' (Smith, 1854) * ''Amegilla dawsoni'' (Rayment, 1951) * ''Amegilla quadrifasciata'' (Villers, 1789) * ''Amegilla violacea'' ( Lepeletier, 1841) * '' Amegilla mucorea'' ( Klug, 1845) * ''Amegilla fallax'' ...
