|}} ''Persoonia linearis'', commonly known as the narrow-leaved geebung, is a shrub native to New South Wales and Victoria in eastern Australia. It reaches , or occasionally , in height and has thick, dark grey papery bark. The leaves are, as the species name suggests, more or less linear in shape, and are up to long, and wide. The small yellow flowers appear in summer and autumn (December to May), followed by small green fleshy fruit known as drupes. Within the genus ''Persoonia'', it is a member of the ''Lanceolata'' group of 58 closely related species. ''P. linearis'' interbreeds with several other species where they grow together. Found in dry sclerophyll forest on sandstone-based nutrient-deficient soils, ''P. linearis'' is adapted to a fire-prone environment; the plants resprout epicormic buds from beneath their thick bark after bushfires. The fruit are consumed by vertebrates such as kangaroo, possums and currawongs. As with other members of the genus, ''P. linearis'' is rare in cultivation as it is very hard to propagate, either by seed or cuttings. It adapts readily to cultivation, preferring acidic soils with good drainage and at least a partly sunny aspect. ==Taxonomy== English botanist and artist Henry Charles Andrews described ''Persoonia linearis'' in 1799, in the second volume of his ''Botanists Repository, Comprising Colour'd Engravings of New and Rare Plants''. He had been given a plant in flower by J. Robertson of Stockwell, who had grown it from seed in 1794. The species name is the Latin ''linearis'' "linear", referring to the shape of the leaves. Meanwhile, German botanist Karl Friedrich von Gaertner had coined the name ''Pentadactylon angustifolium'' in 1807 from a specimen in the collection of Joseph Banks to describe what turned out to be the same species. The genus name derived from the Greek ''penta-'' "five" and ''dactyl'' "fingers", and refers to the five-lobed cotyledons. The horticulturist Joseph Knight described this species as the narrow-leaved persoonia (''Persoonia angustifolia'') in his controversial 1809 work ''On the cultivation of the plants belonging to the natural order of Proteeae'', but the binomial name is illegitimate as it postdated Andrews' description and name. Carl Meissner described a population from the Tambo River in Victoria as a separate variety, ''Persoonia linearis'' var. ''latior'' in 1856, but no varieties or subspecies are recognised.〔 German botanist Otto Kuntze proposed the binomial name ''Linkia linearis'' in 1891, from Cavanilles' original description of the genus ''Linkia'' but the name was eventually rejected in favour of ''Persoonia''. In 1919, French botanist Michel Gandoger described three species all since reallocated to ''P. linearis''; ''P. phyllostachys'' from material collected at Mount Wilson sent to him by the herbarium at the Royal Botanic Gardens in Sydney, and ''P. walteri'' and ''P. breviuscula'' from Melbourne-based plant collector Charles Walter, whose records have been questioned. The short-leaved material of ''P. breviuscula'' was noted to have been collected in Queensland but this is now thought to have been incorrectly recorded.〔 Gandoger described 212 taxa of Australian plants, almost all of which turned out to be species already described.〔 In 1870, George Bentham published the first infrageneric arrangement of ''Persoonia'' in Volume 5 of his landmark ''Flora Australiensis''. He divided the genus into three sections, placing ''P. linearis'' in ''P.'' sect. ''Amblyanthera'', and recognising ''Pentadactylon angustifolium'' as the same species, after examining the specimen in the Banksian Herbarium. He described a variety ''sericea'' from the Shoalhaven River region and also noted the discrepancy in Robert Brown's description of the species. Brown had noted the bark to be smooth, in contrast to Ferdinand von Mueller and others who recorded the bark as layered.〔 The genus was reviewed by Peter Weston for the ''Flora of Australia'' treatment in 1995, and ''P. linearis'' was placed in the ''Lanceolata'' group,〔 a group of 54 closely related species with similar flowers but very different foliage. These species will often interbreed with each other where two members of the group occur, and hybrids with ''P. chamaepeuce'', ''P. conjuncta'', ''P. curvifolia'', ''P. lanceolata'', ''P. media'', five subspecies of ''P. mollis'', ''P. myrtilloides'' subsp. ''cunninghamii'', ''P. oleoides'', ''P. pinifolia'' and ''P. sericea'' have been recorded.〔 Robert Brown initially described the hybrid with ''P. levis'' as a species "''Persoonia lucida''", which is now known as ''Persoonia × lucida'', and has been recorded from the southeast forests of the New South Wales south coast. Bentham wrote in 1870 that the name ''geebung'', derived from the Dharug language word ''geebung'' or ''jibbong'', which had been used by the indigenous people for the fruits of this species.〔 It goes by the common names of narrow-leaved geebung or narrow-leaf geebung.〔 ''Naam-burra'' is an aboriginal name from the Illawarra region. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Persoonia linearis」の詳細全文を読む スポンサード リンク
