Australian Herbarium, Biodiversity and Conservation Science, [10], In 1891, Otto Kuntze proposed to enforce the right of precedent of Banksia J.R.Forst & G.Forst, renaming Pimelea to Banksia, and proposing the name Sirmuellera Kuntze in place of Banksia L.f. Acorn Banksia in Western Australia, October 1998 The Acorn Banksia, Orange Frost (Banksia prionotes) bloom is 3 to 6 inches long and 1 1/2 to 2 inches wide. However Linnaeus incorrectly attributed the Forsters' specimens to the genus Passerina, and therefore considered the name Banksia available for use. Flowers aggregated in → Many species have differing juvenile and adult leaves (e.g., Banksia integrifolia has large serrated juvenile leaves). Woodturners throughout the world value Banksia pods for making ornamental objects. Common name.Banksias. Gynoecium monomerous; of one carpel; superior. South West Only just last year a new species of banksia was discovered an hour and half from Sydney. This can be most spectacular in B. prionotes (acorn banksia) and related species, as the white inflorescence in bud becomes a brilliant orange. Cotyledons 2(–8). → The fruiting inflorescence conelike. The association of P. citricola with diseased Banksia species in South Australia is reported for the first time. Flowers range in colour from red (B. coccinea) to orange/white (B. prionotes). Banksias. or other use of content on this site is unauthorised unless that use The 2,800 square metre Banksia Garden not only houses the entire State collection but also celebrates these sculptural plants in artworks by Philippa O'Brien.

Perianth of Banksia wood is reddish in color with an attractive grain but it is rarely used as it warps badly on drying. Sirmuellera KuntzeIsostylis (R.Br.) Anthers cohering, or connivent, or separate from one another; 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. Involucral bracts not conspicuous. Secondary thickening developing from a Publication There are fossil leaves between 59 and 56 million years old found in southern New South Wales. Furthermore, residents who live in areas near bushland may pressure local councils to burn areas near homes more frequently, to reduce fuel-load in the bush and thus reduce ferocity of future fires.

The terminal inflorescence unit racemose (or two flowered). Dryandra. B. attenuata and B. Involucral bracts often Some species are common and widespread and others are restricted to small isolated occurrences. According to the Australian National Botanic Gardensthere are 76 species of Banksia - with 60 unique to south Western Australia. Fl. & G.Forst by Thomas Sprague. Fruit 0–2 seeded. Entomophilous, or Common name. forming a multiple fruit. Coleman, This web-page only has 4 of these Banksias, but as you will quickly see they are very different from the Banksias found in the Sydney region- and are very special indeed. Follicles compact; septate (septum 6: 4–5. Seeds non-endospermic; compressed; winged. neither androphore nor gynophore. Because dieback thrives in moist soil conditions, it can be a severe problem for Banksias that are watered, such as in the cut flower industry and urban gardens. The genus Banksia now includes species previously classified as Dryandra. Most of the eastern Australian species survive in uplands, but only a few of the Western Australian species native to the Stirling Ranges – B. solandri, B. oreophila, B. brownii and B. montana – survive at high altitudes. 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. deciduous, or persistent. 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. stipules. sessile; bracteate; small to large (often very showy); regular, or somewhat dehiscent, or indehiscent; a follicle. Eastern Australia has far fewer species, but these include some of best known and most widely distributed species, including B. integrifolia (coast banksia) and B. spinulosa (hairpin banksia). Propagation - growing Banksia from seed, cuttings and grafting. ... Banksia baueri Unusual shrub 6'x 6' with large lemon-mauve flowers most of the year. Four species were present in this first collection: B. serrata (Saw Banksia), B. integrifolia (Coast Banksia), B. ericifolia (Heath-leaved Banksia) and B. robur (Swamp Banksia). Embryo straight. Magnoliophyta Banksias grow as trees or woody shrubs. The genus Banksia. Most occur in heathlands or low woodlands; of the eastern species, B. integrifolia and B. marginata occur in forests; many south-western species such as B. grandis, B. sphaerocarpa, B. sessilis, B. nobilis and B. dallanneyi grow as understorey plants in jarrah (Eucalyptus marginata), wandoo (E. wandoo) and karri (E. diversicolor) forests, with B. seminuda being one of the forest trees in suitable habitat. 'Banksia woodlands: A restoration guide for the Swan Coastal Plain' is co-edited by Western Australian scientists Jason Stevens, Deanna Rokich, Vernon Newton, Russell Barrett, and Kingsley Dixon and is published by UWA Press. [39], In 1989, the Banksia Environmental Foundation was created to support and recognise people and organizations that make a positive contribution to the environment. The closest relatives of Banksia are two genera of rainforest trees in North Queensland (Musgravea and Austromuellera). Floral receptacle developing a gynophore, or with Provides authoritative information on the flora of Western Australia. They may need extra water during dry spells until established, which can take up to two years. Managing the Swan River During the Development of Elizabeth Quay Leighton Broad, WA. The Possum Banksia or woolly Banksia is a dense shrub with spikes of orange brown flowers in late winter and spring. Ovary sessile. Dec 10, 2020 - Banksia flowers are Inflorescent: that is, the flower head is made up of hundreds, if not thousands, of tiny flowers. It is related toB.littoralisbut that species has a tree habit, longer serrate leaves and a floral whorl that is hairier inside. Hypogynous disk Banksias range in size from prostrate woody shrubs to trees up to 30 metres tall. [28][29] Other vulnerable species include B. cuneata, and B. verticillata. Spach. Leaves are usually arranged along the branches in irregular spirals, but in some species they are crowded together in whorls. They are also sliced up and sold as drink coasters; these are generally marketed as souvenirs for international tourists. Heterophyllous, or not heterophyllous. Australian Flora. Geography, cytology, number of species. 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. [31], With the exception of the nursery industry, Banksia have limited commercial use. In many species, the resulting structure is a massive woody structure commonly called a cone. A single flower spike generally contains hundreds or even thousands of flowers; the most recorded is around 6000 on inflorescences of B. grandis. or xerophytic. Dieback is notoriously difficult to treat, although there has been some success with phosphite and phosphorous acid, which are currently used to inoculate wild B. brownii populations. Over the years the Mount Barker Banksia Farm has been utilised for all different kinds of scientific studies. Gynoecia of adjoining flowers combining to form a multiple fruit, or not maximize P‐use efficiency through high photosynthetic P‐use efficiency, long leaf lifespan (P residence time), effective P re‐mobilization from senescing leaves, and maximizing seed P concentration. It begins as a creamy white and cream inflorescence. The vast majority of Banksia are found in sandy or gravelly soils, though some populations of B. marginata (silver banksia) and B. spinulosa do occur on soil that is heavier and more clay-like. Banksias were named after Sir Joseph Banks (1743-1820 ), who, in 1770, was the first European to collect specimens of these plants. If fertilised, only slow-release, low-phosphorus fertilizer should be used, as the proteoid roots may be damaged by high nutrient levels in the soil. monticola notable for reaching the biggest banksias and it is the most frost tolerant in this genus, B. seminuda, B. littoralis, B. serrata; species that can grow as small trees or big shrubs: B. grandis, B. prionotes, B. marginata, B. coccinea, B. speciosa and B. menziesii. The Australian Banksia page contains descriptions and photos of over 70 species and cultivars of spectacular Banksias, including Western Australia species. Placentation ornithophilous, or pollinated by unusual means (by small marsupials). Ovules funicled, or sessile; horizontal; Hairs present, or absent. Scientific Description H.R. Inflorescences Most species do not grow well near the coast, notable exceptions being the southern Western Australian species B. speciosa, B. praemorsa and B. repens. Banksia Species, Dainty Banksia, Teasel Banksia (Banksia pulchella) by Kell Jul 30, 2018 5:58 PM Photo courtesy of and copyright of Armella Maria Pratt from Hervey Bay, Queensland The oldest of these are fossil pollen between 65 and 59 million years old. irregular; when irregular, zygomorphic. Inflorescences [20] Many of these animals play a role in pollination of Banksia. woody). [18], Evolutionary scientists Marcell Cardillo and Renae Pratt have proposed a southwest Australian origin for banksias despite their closest relatives being north Queensland rainforest species.[19]. Banksia is a genus of over 200 species in the Protea family (Proteaceae). Inflorescence and flower features. South Australia, Northern Territory, Queensland, New South Wales, Victoria, However this is not without potential problems as it alters the soil composition by adding phosphorus. Within the Australian horticultural community there is an active subculture of Banksia enthusiasts who seek out interesting flower variants, breed and propagate cultivars, exchange materials and undertake research into cultivation problems and challenges. Of the 76 species recorded nationally 62 are endemic to Western Australia, making this genus a justifiable source of local pride. Banksia L.f. → Browse taxa…. [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. [35][36][37] The Noongar people of southwest Western Australia also used infusions of the flower spikes for to relieve coughs and sore throats. We offer flexible appointments, with our online services allowing advanced booking and on the day appointments alongside a range of alternative appointments to suit your busy lifestyle. Banksia - Background Introduction. In some species the follicles open as soon as the seed is mature, but in most species most follicles open only after stimulated to do so by bushfire. These include Banksia hookeriana, B. coccinea, B. baxteri, B. prionotes, B. menziesii, B. speciosa, B. burdettii, B. attenuata and B. grandis. Cook landed on Australian soil for the first time on 29 April 1770, at a place that he later named Botany Bay in recognition of "the great quantity of plants Mr Banks and Dr Solander found in this place". Furthermore, they are of economic importance to Australia's nursery and cut flower industries. By the time Joseph Gaertner corrected Banks' error in 1788, Banksia L.f. was widely known and accepted, so Gaertner renamed Banksia J.R.Forst, & G.Forst to Pimelea, a name previously chosen for the genus by Banks and Solander. Its name comes from its bright pink flower spikes that Banksia species are present throughout the region of suitable rainfall, with greatest speciation in cooler, wetter areas. A number of Banksia species are considered rare or endangered. The Banksia species studied were: B. attenuata R.Br. Seed wings not Fruit and seed features. the next growing season, or persistent; non-fleshy. sailed around the world with Captain Cook 1768–71; collected the largest private Department of Biodiversity, Conservation and Attractions. [1] Banksia species that grow as shrubs are usually erect, but there are several species that are prostrate, with branches that grow on or below the soil. The greatest species richness occurs in association with uplands, especially the Stirling Range. Etymology. Leaves without Linnaeus placed the genus in class Tetrandra, order Monogynia of his father's classification,[7] and named it in honour of Banks. Southwest Western Australia is the main centre of biodiversity; over 90% of all Banksia species occur only there, from Exmouth in the north, south and east to beyond Esperance on the south coast. In recent years the genus Dryandra has … Fertile flowers hermaphrodite. Plants An extinct species, B. novae-zelandiae, was found in New Zealand. There are 173 Banksia species, and all but one occur naturally only in Australia. present; extrastaminal; of separate members (translucent scales). pseudanthial, or not pseudanthial. Luckily, Kevin had already been growing it for years without realising that it was a separate species, so the couple’s arboretum remains complete. Carpel fully closed, or yellow-green, Sep to Dec or Jan. White or grey sand, laterite. Australia extending to Papua New Guinea, Irian Jaya and the Aru Islands. Fruit falling from the plant before About half of Banksia species are killed by bushfire, but these regenerate quickly from seed, as fire also stimulates the opening of seed-bearing follicles and the germination of seed in the ground. Banksia species (Proteaceae) occur on some of the most phosphorus (P)‐impoverished soils in the world. Banksia attenuata, B. menziesii(the dominant Banksiaspecies for Floristic Community Types 21c and 23a), B. ilicifolia and several understorey species at either end of the ranking scale are labelled as illustrations of placement of taxa within the ranking system. non-arillate; orthotropous, or anatropous, or amphitropous, or hemianatropous. Western Australia, Banksia species are generally confined by climate to the south-western corner of the region, with the limits for drought tolerance in the genus corresponding to 250mm anatomy. There is some contention over which species actually provided the inspiration for the "Banksia men": the drawings most resemble the old cones of B. aemula or B. serrata, but B. attenuata (slender banksia) has also been cited, as this was the species that Gibbs saw as a child in Western Australia. These are gradually released over a period of days, either from top to bottom or from bottom to top. B. menziesii R.Br., B. ilicifolia R.Br. Leaf Banksia species are primarily propagated by seed in the home garden as cuttings can be difficult to strike. tetracyclic, or tricyclic. Dieback attacks the roots of plants, destroying the structure of the root tissues, "rotting" the root, and preventing the plant from absorbing water and nutrients. Heavy producers of nectar, banksias are a vital part of the food chain in the Australian bush. The colour of the flowers is determined by the colour of the perianth parts and often the style. Various studies have shown mammals and birds to be important pollinators. (Proteaceae) species were incubated at seven levels of moisture potential (0 to −1.5 MPa) and three constant temperatures (10°C, 15°C and 20°C). incompletely closed; stylate; apically stigmatic; 2 ovuled. This is a common characteristic of many flowers in the Proteaceae family, to which the Banksia belongs. The Indigenous people of south-western Australia would suck on the flower spikes to obtain the nectar, they also soaked the flower spikes in water to make a sweet drink. Matchstick Banksia EPBC Status: Endangered SPRAT Species Profile: Banksia cuneata — Matchstick Banksia Found in: South-west Western Australia Main threats: Phytophthora dieback, habitat fragmentation, invasive weeds, changed fire regimes About This spectacular banksia species grows in the wheatbelt region near Perth. [16] The oldest fossil cones are between 47.8 and 41.2 million years old, found in Western Australia. These include: Perhaps the best known cultural reference to Banksia is the "big bad Banksia men" of May Gibbs' children's book Snugglepot and Cuddlepie. Family Proteaceae. virtually director of the royal gardens at Kew. [37] Banksia trees are a reliable source of insect larvae which are extracted as food. [11][verification needed] In 1940, Banksia L.f. was formally conserved against Banksia J.R.Forst. Another threat to Banksia is the water mould Phytophthora cinnamomi, commonly known as "dieback". During September and October 1791, while the expedition were anchored at King George Sound, he collected numerous plant specimens, including the first specimens of Dryandra (now Banksia) sessilis (Parrotbush) and D. (now Banksia) pellaeifolia. Stamens inserted within a concavity near the and B. littoralis R.Br.These species were selected for their differ-ing dependence upon groundwater. Banksias make excellent cut flowers, as they have a long vase life and excellent range of colors and sizes. encircling body (wings terminal, membranous). Banksias are popular garden plants in Australia because of their large, showy flower heads, and because the large amounts of nectar they produce attracts birds and small mammals. Habit and leaf form.Trees, or shrubs; evergreen. We hypothesized that Banksia spp. However commercial nurserymen extensively utilize the latter method (indeed, cultivars by nature must be vegetatively propagated by cuttings or grafting). Infrequent bushfires at expected intervals pose no threat, and are in fact beneficial for regeneration of banksia populations. Banksia marginata 8100708.1 191c ANBG 50686.2 1950 Banksia spinulosa 681149.1 128 ANBG 52609.1 1952 Eastern species and some Western Australian (WA) species have been successfully grown in the ANBG over many years. The floral asymmetry when present, Nearly every known wild population of B. brownii shows some signs of dieback infection, which could possibly wipe it out within years. Each follicle consists of two horizontal valves that tightly enclose the seeds. Plant deaths in such large proportions can have a profound influence on the makeup of plant communities. In Western Australia, banksias of the first group are known as 'seeders' and the second group as 'sprouters'.[24]. These include B. brownii (feather-leaved banksia), B. cuneata (matchstick banksia), B. goodii (Good's banksia), B. oligantha (Wagin banksia), B. tricuspis (pine banksia), and B. verticillata (granite banksia). The name Banksia had in fact already been published in 1775 as Banksia J.R.Forst & G.Forst, referring to some New Zealand species that the Forsters had collected during Cook's second voyage. Trees, or shrubs; evergreen. Mesophytic, Banksias possibly require more maintenance than other Australian natives, though are fairly hardy if the right conditions are provided (sunny aspect and well drained sandy soil). Not endemic to Australia. Plants hermaphrodite. The leaves of Banksia vary greatly between species. Australian Capital Territory, and Tasmania. For example, in southwestern Australia Banksia often occurs as an understorey to forests of jarrah (Eucalyptus marginata), another species highly vulnerable to dieback. [17] Although Banksia is now only native to Australia and New Guinea, there are fossils from New Zealand, between 21 and 25 million years old. In June the ship was careened at Endeavour River, where specimens of B. dentata (Tropical Banksia) were collected. A number of field guides and other semi-technical books on the genus have been published. The unusual flower spikes grow to 30cm long by 20cm wide. Androecium 4. [26], Vulnerable plants typically die within a few years of infection. Unfortunately there are often discrepancies in agreed frequency between these groups and conservation groups. ‘tepals’; 4; 1 -whorled; free (limb much shorter than the claw); cream, or Banksia grow in non-arid regions all over Australia, but most species grow only in Western Australia. All Western Australian species are vulnerable, although most eastern species are fairly resistant. Leaf blade margins entire, or crenate, or dentate; flat, or revolute. Banksia flowers are usually a shade of yellow, but orange, red, pink and even violet flowers also occur. This is most often seen in Banksia marginata and B. ericifolia[3][4] (pictured right). The exception is B. dentata (tropical banksia), which occurs throughout northern Australia, and on islands to the north including New Guinea and the Aru Islands. Northern Botanical Province, non-sheathing; aromatic, or without marked odour; edgewise to the stem, or with involving the perianth and involving the androecium. Eremaean Botanical Province, and South-West Botanical Province. Some evidence suggests that phosphorous acid may inhibit proteoid root formation.[30]. Coleman, Thursday 8 September 2016. The leaves of most species have serrated edges, but a few, such as B. integrifolia, do not. There are around 170 species. When the styles and perianth parts are different colours, the visual effect is of a colour change sweeping along the spike. The other species occur in two distinct geographical regions: southwest Western Australia and eastern Australia. More than 12 species of Western Australian banksias are suited to cutflower production. Infestation kills both the jarrah overstorey and the original Banksia understorey, and over time these may be replaced by a more open woodland consisting of an overstorey of the resistant Marri (Corymbia calophylla), and an understorey of the somewhat resistant Banksia sessilis (parrot bush).[27]. It is occasionally used for ornamental purposes in wood turning and cabinet paneling. 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 Banksia plants are naturally adapted to the presence of regular bushfires in the Australian landscape. 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 . Studies of the south-western species have found the distribution of Banksia species to be primarily constrained by rainfall. Banksia woodland on the northern Swan Coastal Plain, approximately 35 km north of Perth, Western Australia (31°45′S, 115°57′E). The flowers are arranged in flower spikes or capitate flower heads. Magnoliopsida Unisexual flowers absent. Department of Biodiversity, Conservation and Attractions. [9] Robert Brown gave a lecture, naming the new genus Dryandra in 1809, however Joseph Knight published the name Josephia before Brown published his paper with the description of Dryandra. The multiple fruits coalescing, or not coalescing. “The garden really reflects banksia from all across the country, including species from Kakadu in the Northern Territory,” Mr Taylor said. All respond well to some form of pruning. Reproductive type, pollination. Banksia verticillata is distinguished from other Banksiaspecies by its smooth-edged, whorled leaves that are green above and conspicuously matted with white hairs below. Austin Mast and Kevin Thiele published the official merging of Dryandra within Banksia in 2007, recalibrating the genus into subgenus Banksia and subgenus Spathulatae.[14]. [34] The large "cones" or seed pods of B. grandis are used for woodturning projects. terminal; dense spikes with woody axes, usually globular to cylindric; with Cultivation - growing banksias successfully in a range of climates.

The greatest concentration of species is found in Western Australia. FloraBase is produced by the staff of the Western Seeds of four Western Australia Banksia R.Br. Here they occur from the Eyre Peninsula in South Australia right around the east coast up to Cape York in Queensland. Upon Menzies' return to England, he turned his specimens over to Banks; as with most other specimens in Banks' library, they remained undescribed for many years. The pistil 1 celled.
