Flowers Infrequent bushfires at expected intervals pose no threat, and are in fact beneficial for regeneration of banksia populations. Floral receptacle developing a gynophore, or with Inflorescences After Sir Joseph Banks (1743–1820), prominent patron Some species, principally B. coccinea (scarlet banksia), B. baxteri, B. hookeriana (Hooker's banksia), B. sceptrum (sceptre banksia), and B. prionotes (acorn banksia), and less commonly B. speciosa (showy banksia), B. menziesii (Menzies' banksia), B. burdettii and B. ashbyi are grown on farms in Western and Southern Australia, as well as Israel and Hawaii, and the flower heads harvested for the cut flower trade. Specimens of Banksia were first collected by Sir Joseph Banks and Dr Daniel Solander, naturalists on the Endeavour during Lieutenant (later Captain) James Cook's first voyage to the Pacific Ocean. Proteaceae Juss. connective), or unappendaged. These include miniature forms under 50 cm high of B. spinulosa and B. media, as well as prostrate species such as B. petiolaris and B. blechnifolia . The greatest concentration of species is found in Western Australia. The leaves of Banksia vary greatly between species. Inflorescences Nearly every known wild population of B. brownii shows some signs of dieback infection, which could possibly wipe it out within years. Despite the large number of flowers per inflorescence, only a few of them ever develop fruit, and in some species a flower spike will set no fruit at all. [13], Alex George arranged the genus into two subgenera—subgenus Isostylis (containing B. ilicifolia, B. oligantha and B. cuneata) and subgenus Banksia (containing all other species except those he considered dryandras)—in his 1981 monograph and 1999 treatment for the Flora of Australia series. Flowers 4 merous; cyclic; 1. Various studies have shown mammals and birds to be important pollinators. Plants hermaphrodite. Heterophyllous, or not heterophyllous.

Only a few species, such as B. rosserae and B. elderiana (swordfish banksia), occur in arid areas. The main forum for exchange of information within this group is ASGAP's Banksia Study Group. South Australia, Northern Territory, Queensland, New South Wales, Victoria, [32] The nectar is also sought by beekeepers, not for the quality of the dark-coloured honey, which is often poor, but because the trees provide an abundant and reliable source of nectar at times when other sources provide little.[33]. of the natural sciences; for over 40 years president of the Royal Society; [40], Genus of flowering plants in the family Proteaceae, Field guides and other technical resources, sfn error: no target: CITEREFGeorge1999 (, sfn error: no target: CITEREFWrigleyFagg1991 (, sfn error: no target: CITEREFCollinsCollins2008 (, "Contrasted patterns of hyperdiversification in Mediterranean hotspots", "Evolution of a Hotspot Genus: Geographic Variation in Speciation and Extinction Rates in, Department of Environment and Conservation (Western Australia), "Phytophthora in forests and natural ecosystems", Department of the Environment and Heritage, Thiele and Ladiges' taxonomic arrangement of, https://en.wikipedia.org/w/index.php?title=Banksia&oldid=996453566, Wikipedia articles needing page number citations from August 2016, Short description is different from Wikidata, Wikipedia articles needing factual verification from September 2017, Creative Commons Attribution-ShareAlike License.

However this is not without potential problems as it alters the soil composition by adding phosphorus. Wow stuff about the Banksia Garden • Eighty banksia species displayed – the largest collection on the eastern side of Australia • Extreme horticulture - cutting edge know-how used for growing difficult WA species • 28 species are grown on grafted eastern-states rootstock • special growing media and mounding to provide sharp drainage • heatbank walls for below-zero winter temperatures ornithophilous, or pollinated by unusual means (by small marsupials). "Really Big Banksias". Trees of the largest species, B. integrifolia (coast banksia) and B. seminuda (river banksia), often grow over 15 metres tall, some even grow to standing 30 metres tall. The unusual flower spikes grow to 30cm long by 20cm wide. Mesophytic, adnate; all equal, or markedly unequal; free of one another; 1 -whorled. B. seminuda is exceptional for its preference for rich loams along watercourses. Branched hairs absent. dehiscent, or indehiscent; a follicle. The Banksia Garden celebrates its namesake by showcasing a wide selection of the over-170 species spread across the coasts and hinterland of most of mainland Australia and Tasmania. Spach. the next growing season, or persistent; non-fleshy. There are over 75 species of Banksia, all but one occurring naturally within Australia. The pistil 1 celled. However, establishing so many different WA species presented special challenges since many are no-toriously difficult to grow away from The remaining species usually survive bushfire, either by resprouting from a woody base known as a lignotuber or, more rarely, epicormic buds protected by thick bark. [31], With the exception of the nursery industry, Banksia have limited commercial use.
