Banksia Elderiana
''Banksia elderiana'', commonly known as the swordfish banksia, is a species of shrub in the plant genus ''Banksia''. It is a tangled, bushy shrub with stiff, serrated leaves and spikes of yellow flowers. It occurs in two disjunct areas in the Goldfields-Esperance region of Western Australia. One population extends over a large area from west of Kalgoorlie south to Ravensthorpe, with another population in the Great Victoria Desert north of the Queen Victoria Spring. Description ''Banksia elderiana'' grows as a tangled and bushy shrub to in height, with new growth covered densely with brown fur. The stiff linear narrow leaves are very long and curled, measuring long and wide. The leaf margins are serrated, with many teeth measuring each. Flowering typically occurs between January and March, but may continue into winter. The all-yellow inflorescences hang down from branchlets and measure in length. The inflorescences turn grey as they age, and the old flowers remain as up to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yellowdine, Western Australia
Yellowdine is a town located east of Perth, Western Australia on the Great Eastern Highway. The townsite is in the Goldfields-Esperance region, situated in the Shire of Yilgarn. History The town was initially planned in 1895 as a siding (rail), railway siding along the Coolgardie to Southern Cross railway line that was opened in 1896. Once gold was discovered at Mount Palmer, Western Australia, Mount Palmer close to Yellowdine in 1934 the government began to develop the siding as a town-site that was later gazetted in 1935. The rest house at the railway station was partially destroyed by fire in 1947. The name of the town is believed to be Aboriginal in origin, a misspelling of Yelladine, although its meaning is unknown.

Banksia Lemanniana
''Banksia lemanniana'', the yellow lantern banksia or Lemann's banksia, is a species of flowering plant in the family Proteaceae, native to Western Australia. It generally grows as an open woody shrub or small tree to high, with stiff serrated leaves and unusual hanging inflorescences. Flowering occurs over summer, the greenish buds developing into oval flower spikes before turning grey and developing the characteristic large woody follicles. It occurs within and just east of the Fitzgerald River National Park on the southern coast of the state. ''B. lemanniana'' is killed by bushfire and regenerates from seed. Described by Swiss botanist Carl Meissner in 1856, ''Banksia lemanniana'' was named in honour of English botanist Charles Morgan Lemann. It is one of three or four related species all with pendent inflorescences, which is an unusual feature of banksias. No subspecies are recognised. ''Banksia lemanniana'' is classified as Not Threatened under the Wildlife Conserva ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banksia Attenuata
''Banksia attenuata'', commonly known as the candlestick banksia, slender banksia, or biara to the Noongar people, is a species of plant in the family Proteaceae. Commonly a tree, it reaches high, but it is often a shrub in drier areas high. It has long, narrow, serrated leaves and bright yellow inflorescences, or flower spikes, held above the foliage, which appear in spring and summer. The flower spikes age to grey and swell with the development of the woody follicle (fruit), follicles. The candlestick banksia is found across much of the Southwest Australia, southwest of Western Australia, from north of Kalbarri National Park down to Cape Leeuwin and across to Fitzgerald River National Park. English botanist John Lindley had named material collected by Australian botanist James Drummond (botanist), James Drummond ''Banksia cylindrostachya'' in 1840, but this proved to be the same as the species named ''Banksia attenuata'' by Scottish botanist Robert Brown (botanist, born 1773) ...

Banksia Baueri
''Banksia baueri'', commonly known as the woolly banksia, is a species of shrub that is endemic to the southwest of Western Australia. It has serrated leaves and a distinctively large and hairy looking inflorescence with cream, yellow or brown flowers, and hairy fruit. Description ''Banksia baueri'' grows as a many-branched spreading shrub reaching high, and wide but does not form a lignotuber. Its bark is thin and grey with long fissures, while new growth is covered in fine pale brown fur. New growth occurs in summer. The leaves are usually narrow egg-shaped with the narrower end towards the base, long and wide with serrated edges, tapering to a petiole long. The inflorescence develops over 5–6 months, and can reach in diameter, high and is borne on a short side branch. The flowers are cream, yellow or brown and hairy, the perianth long and the pistil long with a glabrous style. The fruit is a hairy, elliptical follicle long. Taxonomy Robert Brown described '' ...

Banksia Elegans
''Banksia elegans'', commonly known as the elegant banksia, is a species of woody shrub that is Endemism, endemic to a relatively small area of Western Australia. Reaching high, it is a suckering shrub that rarely reproduces by seed. The round to oval yellow flower spikes appear in spring and summer. Swiss botanist Carl Meissner described ''Banksia elegans'' in 1856. It is most closely related to the three species in the Banksia subg. Isostylis, subgenus ''Isostylis''. Description ''Banksia elegans'' grows as a many-stemmed spreading shrub to high. It commonly sends up suckers from either the roots or trunk. The trunk is up to in diameter and covered with grey tessellated bark. The new stems are covered with fine hair and become smooth with maturity. New growth mainly occurs in summer. The long thin pale blue-green leaves are long and wide. Their margins are prominently serrated in a saw-tooth pattern with triangular teeth and v-shaped sinuses. The yellow flower spikes, or i ...

Banksia Subg
''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. As heavy producers of nectar (plant), nectar, they are important sources of food for nectariferous a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polyphyletic
A polyphyletic group is an assemblage of organisms or other evolving elements that is of mixed evolutionary origin. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. ource for pronunciation./ref> It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthetic plants, and edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major revisions of the classification schemes. Researchers concerned more with ecology than with systema ...

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 ...
