Banksia Subser. Cratistylis
''Banksia'' subser. ''Cratistylis'' is a valid botanic name for a subseries of ''Banksia''. It was first published by Kevin Thiele in 1996 but discarded by Alex George in 1999. Cladistics The name came about after a cladistic analysis of ''Banksia'' by Thiele and Pauline Ladiges yielded a phylogeny somewhat at odds with the accepted taxonomic arrangement, the 1981 arrangement of George. Thiele and Ladiges' cladogram included a clade consisting of the members of ''B.'' ser. ''Banksia'' ''sensu'' George, together with the four members of George's ''B.'' ser. ''Crocinae''. This clade divided into two subclades: Taxonomy Thiele and Ladiges accepted this clade as the basis for their ''B.'' ser. ''Banksia'', discarding George's ''B.'' ser. ''Crocinae''. They divided the series into two subseries in accordance with their cladogram, with '' B. ornata'' (Desert Banksia), '' B. serrata'' (Saw Banksia) and '' B. aemula'' (Wallum Banksia) placed in ...

Banksia Menziesii
''Banksia menziesii'', commonly known as firewood banksia, is a species of flowering plant in the genus ''Banksia''. It is a gnarled tree up to tall, or a lower spreading shrub in the more northern parts of its range. The serrated leaves are dull green with new growth a paler grey green. The prominent autumn and winter inflorescences are often two-coloured red or pink and yellow, and their colour has given rise to more unusual common names such as port wine banksia and strawberry banksia. Yellow blooms are rarely seen. First described by the botanist Robert Brown in the early 19th century, no separate varieties of ''Banksia menziesii'' are recognised. It is found in Western Australia, from the Perth (32° S) region north to the Murchison River (27° S), and generally grows on sandy soils, in scrubland or low woodland. ''Banksia menziesii'' provides food for a wide array of invertebrate and vertebrate animals; birds and in particular honeyeaters are prominent visitors. A re ...

Banksia Serrata
''Banksia serrata'', commonly known as the saw banksia, the old man banksia, the saw-tooth banksia or the red honeysuckle and as wiriyagan by the Cadigal people, is a species of woody shrub or tree of the genus ''Banksia'', in the family Proteaceae. Native to the east coast of Australia, it is found from Queensland to Victoria with outlying populations on Tasmania and Flinders Island. Commonly growing as a gnarled tree up to 16 m (50 ft) in height, it can be much smaller in more exposed areas. This ''Banksia'' species has wrinkled grey bark, shiny dark green serrated leaves and large yellow or greyish-yellow flower spikes appearing over summer. The flower spikes, or inflorescences, turn grey as they age and pollinated flowers develop into large, grey, woody seed pods called follicles. ''B. serrata'' is one of the four original ''Banksia'' species collected by Sir Joseph Banks in 1770, and one of four species published in 1782 as part of Carolus Linnaeus the Younger's ...

Pollen-presenter
A pollen-presenter is an area on the tip of the style in flowers of plants of the family Proteaceae on which the anthers release their pollen prior to anthesis. To ensure pollination, the style grows during anthesis, sticking out the pollen-presenter prominently, and so ensuring that the pollen easily contacts the bodies of potential pollination vectors such as bees, birds and nectarivorous mammals. The systematic depositing of pollen on the tip of the style implies the plants have some strategy to avoid excessive self-pollination Self-pollination is a form of pollination in which pollen from the same plant arrives at the stigma of a flower (in flowering plants) or at the ovule (in gymnosperms). There are two types of self-pollination: in autogamy, pollen is transferred .... References * Plant anatomy + Proteaceae {{Botany-stub ...

Carpel
Gynoecium (; ) is most commonly used as a collective term for the parts of a flower that produce ovules and ultimately develop into the fruit and seeds. The gynoecium is the innermost whorl of a flower; it consists of (one or more) ''pistils'' and is typically surrounded by the pollen-producing reproductive organs, the stamens, collectively called the androecium. The gynoecium is often referred to as the "female" portion of the flower, although rather than directly producing female gametes (i.e. egg cells), the gynoecium produces megaspores, each of which develops into a female gametophyte which then produces egg cells. The term gynoecium is also used by botanists to refer to a cluster of archegonia and any associated modified leaves or stems present on a gametophyte shoot in mosses, liverworts, and hornworts. The corresponding terms for the male parts of those plants are clusters of antheridia within the androecium. Flowers that bear a gynoecium but no stamens are called ...

Greek Language
Greek ( el, label=Modern Greek, Ελληνικά, Elliniká, ; grc, Ἑλληνική, Hellēnikḗ) is an independent branch of the Indo-European family of languages, native to Greece, Cyprus, southern Italy (Calabria and Salento), southern Albania, and other regions of the Balkans, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic, and many other writing systems. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of lasting impo ...

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. ...

Banksia Prionotes
''Banksia prionotes'', commonly known as acorn banksia or orange banksia, is a species of shrub or tree of the genus ''Banksia'' in the family Proteaceae. It is native to the southwest of Western Australia and can reach up to in height. It can be much smaller in more exposed areas or in the north of its range. This species has serrated, dull green leaves and large, bright flower spikes, initially white before opening to a bright orange. Its common name arises from the partly opened inflorescence, which is shaped like an acorn. The tree is a popular garden plant and also of importance to the cut flower industry. ''Banksia prionotes'' was first described in 1840 by English botanist John Lindley, probably from material collected by James Drummond the previous year. There are no recognised varieties, although it has been known to hybridise with ''Banksia hookeriana''. Widely distributed in south-west Western Australia, ''B. prionotes'' is found from Shark Bay ( 25° S) in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Banksia Speciosa
''Banksia speciosa'', commonly known as the showy banksia, is a species of large shrub or small tree in the family Proteaceae. It is found on the south coast of Western Australia between Hopetoun (33°57′ S) and the Great Australian Bight (approximately 33° S 130° E), growing on white or grey sand in shrubland. Reaching up to in height, it is a single-stemmed plant that has thin leaves with prominent triangular "teeth" along each margin, which are long and wide. The prominent cream-yellow flower spikes known as inflorescences appear throughout the year. As they age they develop up to 20 follicles each that store seeds until opened by fire. Though widely occurring, the species is highly sensitive to dieback and large populations of plants have succumbed to the disease. Collected and described by Robert Brown in the early 19th century, ''B. speciosa'' is classified in the series ''Banksia'' within the genus. Its closest relative is '' B. baxteri''. ''B. sp ...
