Banksia Ser. Cyrtostylis
''Banksia'' ser. ''Cyrtostylis'' is a taxonomic series within the plant genus ''Banksia''. First published at sectional rank by George Bentham in 1870, it was demoted to a series by Alex George in 1981. The name has had three circumscriptions. According to Bentham Bentham published ''B.'' sect. ''Cyrtostylis'' in ''Flora Australiensis'', as part of his taxonomic arrangement of ''Banksia'', defining it as those taxa with This definition essentially defined ''Cyrtostylis'' as a section for those species that did not possess the characters of the other sections; thus it was highly heterogeneous. George Bentham's placement and circumscription of ''B.'' sect. ''Cyrtostylis'' may be summarised as follows: :''Banksia'' :: ''B.'' sect. ''Oncostylis'' (13 species, 2 varieties) ::''B.'' sect. ''Cyrtostylis'' :::'' B. attenuata'' :::'' B. media'' :::'' B. Solandri'' :::'' B. Goodii'' :::'' B. petiolaris'' :::'' B. repens'' :::''B. prostrata'' ...

Banksia Media
''Banksia media'', the southern plains banksia or golden stalk banksia, is a species of flowering plant in the family Proteaceae. An evergreen shrub, it occurs on the south coast of Western Australia between Albany and Israelite Bay, where it is a common plant. A many-branched bush with wedge-shaped serrated leaves and large golden-yellow flower spikes, known as inflorescences, it grows up to 10 metres (30 ft) high. These plants are killed by bushfire, and regenerate from seed. The flowers attract nectar- and insect-feeding birds, particularly honeyeaters, and a variety of insects. In cultivation, ''Banksia media'' grows well in a sunny location on well-drained soil in areas with dry summers. It is more resilient than most Western Australian banksias when cultivated in areas with humid summers. Description ''Banksia media'' grows as a many-stemmed shrub generally to around 4 m (13 ft) high, though specimens up to 10 m (30 ft) high and 6 m (20&nbs ...

Banksia Petiolaris
''Banksia petiolaris'' is a rare species of flowering plant in the family Proteaceae native to Western Australia, where it is found in sandy soils in the south coastal regions from Munglinup east to Israelite Bay. It was first described by Victorian state botanist Ferdinand von Mueller in 1864, and no subspecies are recognised. ''B. petiolaris'' is one of several closely related species that will all grow as prostrate shrubs, with horizontal stems and thick, leathery upright leaves. Those of this species can be viable for up to 13 years—the longest-lived of any flowering plant recorded. It bears yellow cylindrical flower spikes, known as inflorescences, up to high in spring. As the spikes age, they turn grey and develop up to 20 woody seed pods, known as follicles, each. Insects such as bees, wasps and even ants can pollinate the flowers. ''B. petiolaris'' is nonlignotuberous, meaning it regenerates by seed after bushfire. ''B. petiolaris'' adapts readily to ...

Banksia Ser
''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. ...

Follicle (fruit)
In botany, a follicle is a dry unilocular fruit formed from one carpel, containing two or more seeds. It is usually defined as dehiscing by a suture in order to release seeds, for example in ''Consolida'' (some of the larkspurs), peony and milkweed (''Asclepias''). Some difficult cases exist however, so that the term indehiscent follicle is sometimes used, for example with the genus ''Filipendula'', which has indehiscent fruits that could be considered intermediate between a (dehiscent) follicle and an (indehiscent) achene. An aggregate fruit that consists of follicles may be called a follicetum. Examples include hellebore, aconite, ''Delphinium'', ''Aquilegia'' or the family Crassulaceae, where several follicles occur in a whorl on a shortened receptacle, or ''Magnolia'', which has many follicles arranged in a spiral on an elongated receptacle. The follicles of some species dehisce by the ventral suture (as in ''Banksia''), or by the dorsal suture (as in ''Magnolia'').Kapil, R. ...

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 ...

The Genus Banksia L
''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of pronoun ''thee'') when followed by a ...

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 ...
