banksia marginata hedge

"Variation in, This page was last edited on 18 December 2020, at 16:54. I am growing Banksia sentinel too, and it seems fine. Its natural occurrence is throughout south-eastern Australia; from Eyre Peninsula, South Australia, through Victoria and eastern New South Wales north to Baradine and Guyra, and throughout Tasmania. The response to bushfire varies. Salkin proposed this was necessary so that seed released in a summer or autumn bushfire would lie dormant over the winter months before germinating in the spring. He had collected this form from Revesby in New South Wales as well as Cape Paterson, and had received reports of similar plants at Marlo and Bemm Rivers. Banksia was redefined as encompassing taxa lacking spoon-shaped cotyledons. integrifolia. [73] Propagation of plants can be by seed or cuttings; the latter is essential if trying to replicate plants of particular habit (such as dwarf specimens). In a morphological cladistic analysis published in 1994, Kevin Thiele placed it as the most basal member of a newly described subseries Integrifoliae, within the series Salicinae. [7] The cellular makeup of the leaves shows evidence of lignification, and the leaves themselves are somewhat stiff. It naturally forms a good rounded shape, and pruning after flowering will encourage and even more dense habit. The seed surface can be smooth or covered in tiny ridges, and often glistens. Banksia marginata resolves as the closest relative, or "sister", to B. saxicola, the two taxa part of a larger group containing B. paludosa and the three subspecies of B. [72], B. marginata is generally fairly easy to grow in a well-drained sunny or partly-shaded position in the garden. This attribute might have allowed them to survive cold periods in Tasmania during the Pleistocene. 1891年にはクンツェ (Kunze) が小リンネの名前をSirmuelleraにしようとしたが、受け入れられなかった。 Banksia marginata 'Silver Banksia' A classic woody native Australian shrub, Banksias are great for a low maintenance garden and create interest with their recognizable flower cones. ericifoliaから、45cmの長さの葉のブル・バンクシア (B. grandis) のように非常に大きな葉を持つものまで様々である。 It makes sense to seek out plants that are adapted to dry summer conditions. Bentham observed that the characteristics Brown used to define B. australis, B. depressa, B. patula, and B. insularis were unable to distinguish separate forms as more specimens came to light, and hence declared them synonyms of B. marginata. Agave ovatifolia and Delosperma Rainfall in the Pacific Northwest takes an annual break during our summers when days are longest and hottest and evaporation far exceeds anything that falls from the sky. [47], In Tasmania, Banksia marginata occupies a wide range of habitats, in mixed forest (where it grows as a small tree), button grass moorlands, flood plains of the Loddon, Franklin and Huon Rivers, as well as coastal regions. [22] Brown's other collections which were reduced to synonymy with B. marginata were Banksia depressa R.Br., a prostrate shrub from Margate Rivulet in southeastern Tasmania, Banksia insularis R.Br., from Flinders and King Island, and Banksia patula R.Br., a shrub from the vicinity of Port Lincoln, South Australia. The galls are either round to a diameter of 3.3 cm (1.3 in), or cigar-shaped to 15 cm (5.9 in). This Australian native tree has a dense growth habit with long green leaves bearing silver undersides. Their effect on the plant is unclear. [55] Much more pathological is the banksia longicorn beetle (Paroplites australis) which bores holes in the base of banksia plants which then weaken and fall or blow over with wind and die. Banksia marginata varies widely in habit, ranging from a 20-centimetre (7.9 in) shrub to a 12-metre (40 ft) tree. Banksia insularis R.Br. [17] The species marginata was first collected by Luis Née in 1793, from somewhere between Sydney and Parramatta. In 1800, the Spanish botanist Antonio José Cavanilles gave the species the binomial name it still bears today. [9] Alternate common names include honeysuckle and dwarf honeysuckle. [1], By the time Carl Meissner published his 1856 arrangement of the genus, there were 58 described Banksia species. Calling it the Wilsons Promontory topodeme, he noted that it colonised sand dunes, had leaves similar to but narrower than integrifolia, and had persisting flowers on old spikes but not as persistent as marginata. astroluxが現在査読中で、間もなく種のレベルに昇格されるであろう。, バンクシア属は2つの亜属に分けられる。イソスティリス亜属 (Banksia subg. The flower spikes fade to brown and then grey and develop woody follicles bearing the winged seeds. There is anecdotal evidence of plants reaching 150 years old in this region. Banksia gunnii Meisn. [26], The current taxonomic arrangement of the genus Banksia is based on botanist Alex George's 1999 monograph for the Flora of Australia book series. In many populations, only a few follicles develop. [12] In Victoria, it is predominantly coastal or near-coastal east of Traralgon, but in New South Wales it is absent from coastal areas in the Sydney region. 葉は枝に不規則ならせん状に並ぶのが普通だが、いくつかの種では輪生に集まる。, バンクシアはその特徴的な穂状花序と、花の後にできる木質の果実によって容易に認識できる。花序は柔毛質の覆いのある木質の軸でできている。通常は直立しているが、いくつかの種では垂下している。これは、軸に対して直角に着いた、密に配列した花によって覆われる。単一の花序で1000以上の花が含まれる。, バンクシアの花は通常は黄色の色調を持つが、橙色、赤や桃色の花もある。花の色は花被または花柱によって決まる。花柱は花被よりかなり長く、初期には花被の上部で引っかかる。数日かけて上部から、または下部(の花)から離れていく。花柱と花被の色が異なっている場合、花序の上と下で花の色が異なって見える効果をもたらす。, 時間が経つと、花は乾燥していき褐色の色調が強くなる。いくつかの種では古い花は脱落し、柔毛質の軸が現れる。他の種では数年にわたって花は宿存し、毛の生えた花序の姿が残る。古い花序は球果(厳密にはソテツと球果類のみにある)とよばれる。, 花序が巨大で花の数が多いにもかかわらず、果実をつけるものは少数で、全く果実をつけない花序もある。バンクシアの果実は「球果」に並んだ木質の袋果である。果実は水平に並んだ弁状の構造が種子を堅くつつんでいる。袋果は縫合から裂けて種子を放出するが、いくつかの種では弁も裂開する。果実は種子が熟したときに裂開するものもあるが、多くの種では山火事によって刺激を受けたときにのみ裂ける。袋果はふつうは小さな種子を二つ含んでおり、くさび形の紙質の翼をもっていて落下するときに回転するようになっている。, 1種を除きバンクシアはオーストラリアに固有である。 また、小型のボートの竜骨を作るのに使われてきた。 As flowering cycles are not interrupted by regular pruning, an abundance of flowers and birds can also be enjoyed. ex Spreng. [25], In 1870, George Bentham published a thorough revision of Banksia in his landmark publication Flora Australiensis. バンクシアは種子で簡単に繁殖でき、多くの種は挿木で殖やせる。 [35] Salkin observed an intermediate form which occurred in coastal areas where Banksia marginata and B. integrifolia are found together.
