Proteaceae
The Proteaceae form a family of flowering plants predominantly distributed in the Southern Hemisphere. The family comprises 83 genera with about 1,660 known species. Together with the Platanaceae and Nelumbonaceae, they make up the order Proteales. Well-known genera include '' Protea'', '' Banksia'', '' Embothrium'', '' Grevillea'', '' Hakea'' and '' Macadamia''. Species such as the New South Wales waratah (''Telopea speciosissima''), king protea ('' Protea cynaroides''), and various species of ''Banksia'', ''soman'', and ''Leucadendron'' are popular cut flowers. The nuts of '' Macadamia integrifolia'' are widely grown commercially and consumed, as are those of Gevuina avellana on a smaller scale. Australia and South Africa have the greatest concentrations of diversity. Etymology The name Proteaceae was adapted by Robert Brown from the name Proteae coined in 1789 for the family by Antoine Laurent de Jussieu, based on the genus ''Protea'', which in 1767 Carl Linnaeus de ...

On The Proteaceae Of Jussieu
''On the natural order of plants called Proteaceae'', also published as "On the Proteaceae of Jussieu", was a paper written by Robert Brown on the taxonomy of the plant family Proteaceae. It was read to the Linnean Society of London in the first quarter of 1809, and published in March 1810. It is significant for its contribution to the systematics of Proteaceae, and to the floristics of Australia, and also for its application of palynology to systematics. Background Brown had been botanist during Matthew Flinders' circumnavigation of Australia, and since returning in England in 1805 he had been preparing descriptions of the specimens collected during the voyage. Brown's intention was to publish a flora of Australia, but this was still incomplete in September 1808 when Jonas Dryander asked Brown to write a monograph on the Proteaceae so that Dryander could use Brown's names in a new edition of '' Hortus Kewensis''. Brown immediately set to work researching the topic. In prep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banksia
''Banksia'' is a genus of around 170 species in the plant family Proteaceae. These Australian wildflowers and popular garden plants are easily recognised by their characteristic flower spikes, and fruiting "cones" and heads. ''Banksias'' range in size from prostrate woody shrubs to trees up to 30 metres (100 ft) tall. They are found in a wide variety of landscapes: sclerophyll forest, (occasionally) rainforest, shrubland, and some more arid landscapes, though not in Australia's deserts. Heavy producers of nectar, ''banksias'' are a vital part of the food chain in the Australian bush. They are an important food source for nectarivorous animals, including birds, bats, rats, possums, stingless bees and a host of invertebrates. Further, they are of economic importance to Australia's nursery and cut flower industries. However, these plants are threatened by a number of processes including land clearing, frequent burning and disease, and a number of species are rare and endangered ...

Telopea Speciosissima
''Telopea speciosissima'', commonly known as the New South Wales waratah or simply waratah, is a large shrub in the plant family Proteaceae. It is endemic to New South Wales in Australia and is the floral emblem of that state. No subspecies are recognised, but the closely related ''Telopea aspera'' was only recently classified as a separate species. ''T. speciosissima'' is a shrub to high and wide, with dark green leaves. Its several stems arise from a pronounced woody base known as a lignotuber. The species is well renowned for its striking large red springtime inflorescences (flowerheads), each including hundreds of individual flowers. These are visited by the eastern pygmy possum (''Cercartetus nanus''), birds such as honeyeaters (Meliphagidae), and various insects. The floral emblem for its home state of New South Wales, ''Telopea speciosissima'' has featured prominently in art, architecture, and advertising, particularly since Australian federation.

Embothrium
''Embothrium'' is a genus of two to eight species (depending on taxonomic interpretation) in the plant family Proteaceae, native to southern South America, in Chile and adjacent western Argentina; the genus occurs as far south as Tierra del Fuego. Common names include Chilean firebush in English, notro in Argentina, ciruelillo, fosforito or notro chileno in Chilean Spanish. They are large shrubs or trees growing to 10–20 m tall with a trunk up to 70 cm diameter. ''E. coccineum'' and perhaps others, is also highly prone to suckering and unmanaged plants often form dense groves of many suckering shoots. The leaves are evergreen, occasionally deciduous in cold areas, 5–12 cm long and 2–4 cm broad. The flowers are produced in dense bunches, brilliant red (rarely white or yellow), tubular, 2.5-4.5 cm long, split into four lobes near the apex which reflex to expose the stamens and style. Systematics One or possibly two extant species are recognised. Two f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protea
''Protea'' () is a genus of South African flowering plants, also called sugarbushes (Afrikaans: ''suikerbos''). Etymology The genus ''Protea'' was named in 1735 by Carl Linnaeus, possibly after the Greek god Proteus, who could change his form at will, possibly because they have such a wide variety of forms. Linnaeus's genus was formed by merging a number of genera previously published by Herman Boerhaave, although precisely which of Boerhaave's genera were included in Linnaeus's ''Protea'' varied with each of Linnaeus's publications. Taxonomy The family Proteaceae to which ''Protea'' species belong is an ancient one among angiosperms. Evidence from pollen fossils suggests Proteaceae ancestors grew in Gondwana, in the Upper Cretaceous, 75–80 million years ago. The Proteaceae are divided into two subfamilies: the Proteoideae, best represented in southern Africa, and the Grevilleoideae, concentrated in Australia and South America and the other smaller segments of Gondwana that ...

Macadamia
''Macadamia'' is a genus of four species of trees in the flowering plant family Proteaceae. They are indigenous to Australia, native to northeastern New South Wales and central and southeastern Queensland specifically. Two species of the genus are commercially important for their fruit, the macadamia nut (or simply macadamia). Global production in 2015 was . Other names include Queensland nut, bush nut, maroochi nut, bauple nut and Hawaii nut. In Australian Aboriginal languages, the fruit is known by names such as ''bauple'', ''gyndl'' or ''jindilli'' (north of Great Dividing Range) and ''boombera'' (south of the Great Range). It was an important source of bushfood for the Aboriginal peoples who are the original inhabitants of the area. The nut was first commercially produced on a wide scale in Hawaii, where Australian seeds were introduced in the 1880s, and for some time, they were the world's largest producer. South Africa has been the world's largest producer of the mac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gevuina Avellana
''Gevuina avellana'' (Chilean hazelnut ( in Spanish), or ''Gevuina hazelnut''), is an evergreen tree, up to 20 meters (65 feet) tall. It is the only species currently classified in the genus ''Gevuina''. It is native to southern Chile and adjacent valleys in Argentina. It is found from sea level to 700 meters (2300 feet) above sea level. Its distribution extends from 35° to 44° south latitude. The composite leaves are bright green and toothed, and the tree is in flower between July and November. The flowers are very small and beige to whitish, are bisexual and group two by two in long racemes. The fruit is a dark red nut when young and turns black. The peel is woody. It can grow up straight or branched from the soil, making up either a tree or a shrub. The name ''Gevuina'' comes from , the Mapuche Indigenous name for the Chilean hazel. The origin of the Spanish name, ''avellano'' come from the fact the Spanish settlers found the nuts similar to the hazelnuts they knew from ...

Proteales
Proteales is an order of flowering plants consisting of three (or four) families. The Proteales have been recognized by almost all taxonomists. The representatives of the Proteales are very different from each other. The order contains plants that do not look alike at all. What they have in common is seeds with little or no endosperm. The ovules are often atropic. Families In the classification system of Dahlgren the Proteales were in the superorder Proteiflorae (also called Proteanae). The APG II system of 2003 also recognizes this order, and places it in the clade eudicots with this circumscription: * order Proteales :* family Nelumbonaceae :* family Proteaceae family Platanaceae">Platanaceae.html" ;"title=" family Platanaceae"> family Platanaceae with "+ ..." = optionally separate family (that may be split off from the preceding family). The APG III system of 2009 followed this same approach, but favored the narrower circumscription of the three families, firmly rec ...

Protea Cynaroides
''Protea cynaroides'', also called the king protea, is a flowering plant. It is a distinctive member of ''Protea'', having the largest flower head in the genus. The species is also known as giant protea, honeypot or king sugar bush. It is widely distributed in the southwestern and southern parts of South Africa in the fynbos region. The king protea is the national flower of South Africa. It also is the flagship of thProtea Atlas Project run by the South African National Botanical Institute. The king protea has several colour forms and horticulturists have recognized 81 garden varieties, some of which have injudiciously been planted in its natural range. In some varieties the pink of the flower and red borders of leaves are replaced by a creamy yellow. This unusual flower has a long vase life in flower arrangements, and makes for an excellent dried flower. ''Protea cynaroides'' is adapted to survive wildfires by its thick underground stem, which contains many dormant buds; these ...

Hakea
''Hakea'' ( ) is a genus of about 150 species of plants in the Family ''Proteaceae'', endemic to Australia. They are shrubs or small trees with leaves that are sometimes flat, otherwise circular in cross section in which case they are sometimes divided. The flowers are usually arranged in groups in leaf axils and resemble those of other genera, especially ''Grevillea''. Hakeas have woody fruit which distinguishes them from grevilleas which have non-woody fruit which release the seeds as they mature. Hakeas are found in every state of Australia with the highest species diversity being found in the south west of Western Australia. Description Plants in the genus ''Hakea'' are shrubs or small trees. Some species have flat leaves, whilst others have leaves which are needle-like, in which case they are sometimes divided and sometimes have a groove on the lower surface. The flowers are arranged in groups in leaf axils and are surrounded by bracts when in bud. The flowers have both male ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stirlingia
''Stirlingia'', commonly known as blueboy, is a genus of 7 species in the family Proteaceae, all of which are endemic to Western Australia. Description ''Stirlingia'' grows as a shrub or herb arising from a perennial tap root or woody root stock; the herbaceous nature of some species is unique to ''Stirlingia'' among the Proteaceae. They grow to heights ranging from 10 centimetres to 1.5 metres. Leaves are soft and leathery, and bifurcated along their length. They occur mostly on lower parts of the stems. Flowers occur in inflorescences that are either heads or very short spikes. Taxonomy The genus was first published by Robert Brown in 1810, under the name ''Simsia''. Brown initially published two species, ''Simsia anethifolia'' and ''Simsia tenuifolia'', adding a third, ''Simsia latifolia'' in 1830. It was later discovered that Brown's generic name was illegal, as the name '' Simsia'' had already been published in 1807 by Christian Hendrik Persoon. Therefore, in 1838 Stephan ...

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 ...
