Banksia Burdettii
''Banksia burdettii'', commonly known as Burdett's banksia, is a species of shrub or tree of the genus ''Banksia'' in the family Proteaceae. It occurs on sandplain country north of Gingin, Western Australia. Growing to 4 m (13 ft) in height, it has long serrated leaves and large, bright flower spikes, initially white before opening to a bright orange, that appear mainly in late summer (February and March). Edmund Gilbert Baker described ''B. burdettii'' in 1934, naming it after its collector, W. Burdett. Description ''Banksia burdettii'' grows as an evergreen shrub to a height of . The new growth is hairy, though longer stems are smooth. The sturdy, serrated grey green leaves are long and wide with a narrow oblong or wedge-shape and a truncate tip. The toothed margins are slightly downcurved. Burdett's banksia has cm high flower spikes, known as inflorescences, that prominently displayed on the ends of stems, appearing between the months of January and May, peaking ...

Perianth
The perianth (perigonium, perigon or perigone in monocots) is the non-reproductive part of the flower, and structure that forms an envelope surrounding the sexual organs, consisting of the calyx (sepals) and the corolla (petals) or tepals when called a perigone. The term ''perianth'' is derived from Greek περί (, "around") and άνθος (, "flower"), while ''perigonium'' is derived from περί () and γόνος (, "seed, sex organs"). In the mosses and liverworts (Marchantiophyta), the perianth is the sterile tubelike tissue that surrounds the female reproductive structure (or developing sporophyte). Flowering plants In flowering plants, the perianth may be described as being either dichlamydeous/heterochlamydeous in which the calyx and corolla are clearly separate, or homochlamydeous, in which they are indistinguishable (and the sepals and petals are collectively referred to as tepals). When the perianth is in two whorls, it is described as biseriate. While the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Austin Mast
Austin R. Mast is a research botanist. Born in 1972, he obtained a Ph.D. from the University of Wisconsin–Madison in 2000. He is currently a professor within the Department of Biological Science at Florida State University (FSU), and has been director of FSU's Robert K. Godfrey Herbarium since August 2003. One of his main areas of research is the phylogenetics of Grevilleoideae, a subfamily of Proteaceae. In 2005 he showed the genus ''Banksia'' to be paraphyletic with respect to ''Dryandra'', Collaborating with Australian botanist Kevin Thiele, he subsequently transferred all ''Dryandra'' taxa to ''Banksia'', publishing over 120 taxonomic names in the process. The change has been adopted by the Western Australian Herbarium, although has met with some controversy. He has previously worked on the Deep South Plant Specimen Imaging Project, which created a repository of annotated high-resolution digital images of plant specimens within the East Gulf Coastal Plain The Gulf Coastal ...

Banksia Victoriae
''Banksia victoriae'', commonly known as Woolly Orange Banksia, is a species of large shrub or small tree in the plant genus ''Banksia''. It occurs in Western Australia between Northampton, Western Australia and Kalbarri, with the occasional plant further north as far as Zuytdorp Nature Reserve. Description ''B. victoriae'' generally grows as a tall shrub, but older plants sometimes attain a tree habit, growing as high as seven metres. It has smooth grey back and densely hairy stems. Leaves are long and wide, with deep triangular lobes and woolly surfaces. Flowers occur in typical ''Banksia'' "flower spikes", inflorescences made up of hundreds of pairs of flowers densely packed in a spiral about a woody axis. ''B. victoriae'''s inflorescence is orange, long. After flowering, up to 30 follicles develop in the flower spike. These are usually concealed by withered flower parts, which persist on the spike for a long time. Taxonomy Discovery and naming The first ...

Banksia Hookeriana
''Banksia hookeriana'', commonly known as Hooker's banksia, is a species of shrub of the genus ''Banksia'' in the family Proteaceae. It is native to the southwest of Western Australia and can reach up to high and wide. This species has long narrow serrated leaves and large, bright flower spikes, initially white before opening to a bright orange that appear over the cooler months. The flowers are pollinated by honeyeaters. The ageing flower spikes develop woody seed pods known as follicles. ''B. hookeriana'' is serotinous — large numbers of seeds are stored in the plant canopy for years until the plants are burnt by bushfire. Description ''Banksia hookeriana'' grows as an bushy shrub to around in diameter, and high. pp. 118–19. It has smooth bark. New growth appears in spring and summer. Anywhere up to several hairy -long branchlets arise from just below nodes on larger branches. The leaves themselves are scattered along the branchlets but more crowded toward the tips. The ...

George's Taxonomic Arrangement Of Banksia
Alex George's taxonomic arrangement of ''Banksia'' was the first modern-day arrangement for that genus. First published in 1981 in the classic monograph '' The genus Banksia L.f. (Proteaceae)'', it superseded the arrangement of George Bentham, which had stood for over a hundred years. It was overturned in 1996 by Kevin Thiele and Pauline Ladiges, but restored by George in 1999. A recent publication by Austin Mast and Kevin Thiele suggests that it will soon be overturned again. Background ''Banksia'' is a genus of around 80 species in the plant family Proteaceae. An iconic Australian wildflower and popular garden plant, they are easily recognised by their characteristic flower spikes and fruiting "cones". They grow in forms varying from prostrate woody shrubs to trees up to 35 metres tall, and occur in all but the most arid areas of Australia. As heavy producers of nectar, they are important sources of food for nectariferous animals such as honeyeaters and honey possum, and they ...

Banksia Subser
''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. ...

Thiele And Ladiges' Taxonomic Arrangement Of Banksia
Kevin Thiele and Pauline Ladiges taxonomic arrangement of ''Banksia'', published in 1996, was a novel taxonomic arrangement that was intended to align the taxonomy of ''Banksia'' more closely with the phylogeny that they had inferred from their cladistic analysis of the genus. It replaced Alex George's 1981 arrangement, but most aspects were not accepted by George, and it was soon replaced by a 1999 revision of George's arrangement. However some herbaria have continued to follow Thiele and Ladiges on some points. Background ''Banksia'' is a genus of around 80 species in the plant family Proteaceae. An iconic Australian wildflower and popular garden plant, they are easily recognised by their characteristic flower spikes and fruiting "cones". They grow in forms varying from prostrate woody shrubs to trees up to 35 metres tall, and occur in all but the most arid areas of Australia.

Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach ...

Cladistics
Cladistics (; ) is an approach to biological classification in which organisms are categorized in groups (" clades") based on hypotheses of most recent common ancestry. The evidence for hypothesized relationships is typically shared derived characteristics ( synapomorphies'')'' that are not present in more distant groups and ancestors. However, from an empirical perspective, common ancestors are inferences based on a cladistic hypothesis of relationships of taxa whose character states can be observed. Theoretically, a last common ancestor and all its descendants constitute a (minimal) clade. Importantly, all descendants stay in their overarching ancestral clade. For example, if the terms ''worms'' or ''fishes'' were used within a ''strict'' cladistic framework, these terms would include humans. Many of these terms are normally used paraphyletically, outside of cladistics, e.g. as a 'grade', which are fruitless to precisely delineate, especially when including extinct species. R ...
