He placed B. integrifolia in series Salicinae, and further divided it into three varieties: B. i. var. [32], B. integrifolia flowers have an unusually short life span for Banksia species, producing nectar for only about four to twelve days after anthesis. oblongifolia by Karel Domin in 1930, but this was overturned by George in 1981,[6] and B. oblongifolia remains a current species name. Salicinae. This would be the first infraspecific taxon of B. integrifolia to achieve widespread acceptance. Until recently, B. integrifolia's taxonomic placement within the genus was largely settled, with the species placed in Banksia subg. Every specimen collected during the Endeavour voyage was sketched by Banks' botanical illustrator Sydney Parkinson. [46], B. integrifolia produces a dark amber-coloured honey of middling quality and therefore low commercial value.

Curtis's Botanical Magazine; 2770. compar remains a current taxon to date. He argued that there was insufficient evidence for the division, and that "B. dentata is clearly allied to B. integrifolia, not to the very distinctive B. B. integrifolia subsp. [6] This was promoted to subspecific rank by Thiele in 1994,[16] and in 1996 George promoted it to specific rank as Banksia aquilonia. monticola. It flowers well in cultivation and flowers attract many birds. Kuntze transferred all Banksia taxa to the new name Sirmuellera; thus B. integrifolia became Sirmuellera integrifolia (L.f.) Kuntze. These concerns aside, B. integrifolia does not appear to be under threat. Leaves are stiff, dark green and serrated as is the parent, the Old Man Banksia. The leaves are dark green with a white underside, and occur in whorls of three to five. [7], B. integrifolia is a highly variable species. B. integrifolia subsp. The species is divided into three subspecies: B. i. subsp. Each follicle contains one or sometimes two seeds, separated by a thin wooden separator. [9] Another purported hybrid with B. marginata, thought to be from Cape Paterson on Victoria's south coast, was first described by Alf Salkin and is commercially available in small quantities. Coast banksia is an attractive shrub or tree with upright, cylindrical heads of pale yellow flowers, suitable for coastal planting in frost-free, temperate areas. These enhance solubilisation of nutrients, thus allowing nutrient uptake in low-nutrient soils such as the phosphorus-deficient native soils of Australia. The latter is a vigorous ground-hugging plant that can spread to 4 or 5 metres across yet remains only 50 centimetres high. Thus the species with entire leaf margins was given the specific name integrifolia, from the Latin integer, meaning "entire", and folium, meaning "leaf". [11], The flower spikes are not as prominent as in some other Banksia species, as they arise from two- to three-year-old nodes nested within the foliage. [8] In this arrangement, B. integrifolia is placed in Banksia subg. [6], In 1800, Antonio José Cavanilles published a number of new Banksia species based on specimens collected at Port Jackson, New South Wales in 1797 by Luis Née, botanist to the Alejandro Malaspina expedition. [6] In 1810, Robert Brown relegated the name to synonymy with B. integrifolia,[7] and it remained so until 1981 when Alex George refined it to a synonym of the autonym B. i. var. [14] Kuntze's challenge failed, as did a similar challenge by James Britten in 1905. This distinctive native tree is found on the east coast of Australia. Its hardiness has prompted research into its suitability for use as a rootstock in the cut flower trade, but has also caused concerns about its potential to become a weed outside of its natural habitat. integrifolia. Salicinae, although no hybrid names have been formally published to date. [2], The genus Banksia was eventually described by Carolus Linnaeus the Younger in his April 1782 publication Supplementum Plantarum. It is a popular choice for parks and streetscapes, and has been used for bush revegetation and stabilisation of dunes. Banksia because of its straight styles; and Banksia ser. Banksia integrifolia subsp. [45] It is a useful firewood.

Kevin Thiele additionally placed it in a subseries Integrifoliae,[16] but this was not supported by George. [35], Unlike most Banksia species, B. integrifolia does not require bushfire to trigger the release of its seed. The style ends are initially trapped inside the upper perianth parts, but break free at anthesis. Rare pink form sometimes available B. integrifolia subsp. It is often found on cliffs or hillsides and on the coast right down to the shoreline. Banksia because of its straight styles; and Banksia ser. Spathulatae for the species having spoon-shaped cotyledons. Coast Banksia. In this montane habitat, it occurs in association with Eucalyptus species such as E. viminalis (manna gum) and E. pauciflora (snow gum), and also rainforest species such as Nothofagus moorei (Antarctic beech) and Orites excelsa (prickly ash). Best grown in full sun and moderately frost-hardy. Coastal Banksia also have larger leaves and flowers and leaves are whorled around the stem (several coming out from the same point on the stem) instead of alternate like on the Silver Banksia. Great street tree and landscape specimen. Scientific Name: Banksia L.f. (Proteaceae) integrifolia L.f. Related Plants. It produces silvery grey flower spikes and cones. It is considered highly decorative, but it warps badly on drying,[30] has poor load-bearing qualities, and is susceptible to termite attack;[42] it is therefore unsuitable for most construction purposes. Leaf margins are serrated with lobes between 1 mm and 3 mm deep. integrifolia. Banksia integrifolia. The Latin integer (entire) and folium (a leaf), refer to the margins of the adult leaf. In some forms, the leaf edges are wavy. integrifolia - Coast Banksia This hardy Banksia grows very well in coastal areas and can tolerate salt spray. Banksia integrifolia – Coast Banksia This variable, adaptable and beautiful banksia will grow slowly to eventually attain tree size, and suits many different positions from coastal gardens where it will handle salt laden winds with ease, to inland cooler areas where it is frost and drought tolerant. Banksia, because its inflorescences take the form of Banksia's characteristic flower spikes; Banksia sect. More research is needed before the technique will be ready for commercial use. It is highly variable in form, but is most often encountered as a tree up to 25 metres (82 ft) in height. Coast banksia is an attractive shrub or tree with upright, cylindrical heads of pale yellow flowers, suitable for coastal planting in frost-free, temperate areas. Seeds do not require any treatment, and take 5 to 6 weeks to germinate. It 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 original description of the genus. [10][30], Between Sydney and Brisbane, B. integrifolia is found up to 200 kilometres (125 mi) inland, with B. integrifolia subsp. [12] However, the second of these varieties was based upon a specimen of B. integrifolia with juvenile leaves, and the last was B. robur.
