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). Stamens inserted within a concavity near the 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. 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. They are an important food source for all sorts of nectarivorous animals, including birds, bats, rats, possums, stingless bees and a host of invertebrates. Due to their size these species are popularly planted in parks, gardens and streets, the remaining species in this genus are only shrubs. Magnoliopsida 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). Perianth of The genus Banksia now includes species previously classified as Dryandra. Banksias make excellent cut flowers, as they have a long vase life and excellent range of colors and sizes. Each follicle usually contains one or two small seeds, each with a wedge-shaped papery wing that causes it to spin as it falls to the ground. The multiple fruits coalescing, or not coalescing. In most cases, the individual flowers are tall, thin saccate (sack-shaped) in shape.

[39], In 1989, the Banksia Environmental Foundation was created to support and recognise people and organizations that make a positive contribution to the environment. Banksia - Background Introduction. Banksias were named after Sir Joseph Banks (1743-1820 ), who, in 1770, was the first European to collect specimens of these plants. neither androphore nor gynophore. Inflorescences 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. Eastern species, such as B. ericifolia, B. robur and B. plagiocarpa, are sometimes cultivated for this purpose. Cotyledons 2(–8). It begins as a creamy white and cream inflorescence. Hairs present, or absent. At the request of Joseph Banks, Menzies collected natural history specimens wherever possible during the voyage.

Sirmuellera KuntzeIsostylis (R.Br.) A single flower spike generally contains hundreds or even thousands of flowers; the most recorded is around 6000 on inflorescences of B. grandis. The style is much longer than the perianth, and is initially trapped by the upper perianth parts. [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.

Hotter, drier regions around the edges of its range tend to have fewer species with larger distributions. Sizes vary from the narrow, 1–1½ centimetre long needle-like leaves of B. ericifolia (heath-leaved banksia), to the very large leaves of B. grandis (bull banksia), which may be up to 45 centimetres long. It is occasionally used for ornamental purposes in wood turning and cabinet paneling. Following the recommendation of the Threatened Species Scientific Committee, the federal Minister for Environment accepted the conservation advice and the subsequent listing of ‘Banksia W… Phytophthora cinnamomi was the species isolated most frequently from soil associated with dead or dying proteaceous plants in the Adelaide region of South Australia. → This is most often seen in Banksia marginata and B. ericifolia[3][4] (pictured right). or xerophytic.

The other species occur in two distinct geographical regions: southwest Western Australia and eastern Australia. 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. However commercial nurserymen extensively utilize the latter method (indeed, cultivars by nature must be vegetatively propagated by cuttings or grafting).
