''Persoonia terminalis'', also known as the Torrington geebung, is a rare shrub belonging to the family Proteaceae native to northern New South Wales and southern Queensland in eastern Australia.〔 Initially reported as a subspecies of ''Persoonia nutans'' in 1981, it was described as a species by Lawrie Johnson and Peter Weston in 1991. Two subspecies are recognised; both are found on acidic, well-drained soils in sclerophyll forests, with one a component of granite outcrops. Although similar in appearance, they differ in leaf length and curvature. Both have a restricted range, with subspecies ''terminalis'' being found in an area of under . ''Persoonia terminalis'' grows to , with an upright or spreading habit, with narrow short leaves to in length. The yellow flowers mainly appear in December and January (Australia's temperate zone summer),〔 and are followed thereafter by purple-striped green drupes (stone fruit). The fruit of all persoonias are eaten (and seeds dispersed) by undomesticated extant vertebrates. ==Taxonomy== ''Persoonia terminalis'' was first treated by Lawrie Johnson of the Royal Botanic Gardens, Sydney in the 1981 edition of ''Flora of New South Wales'' as a distinctive subspecies of ''Persoonia nutans'', a broadly defined species that included many forms later classified as separate species. Queensland botanists Trevor Donald Stanley and Estelle M. Ross classed it as a subspecies of ''Persoonia oxycoccoides'' in their 1986 work ''Flora of South-eastern Queensland'', though considered it more likely to be a species in its own right. Upon re-examining these species, Johnson and colleague Peter Weston concluded that there were several distinct species and ''Persoonia terminalis'' was described as such in 1991. The type specimen was collected south of the Torrington pub on the Emmaville–Torrington road by Weston and Peter Richards, and is now housed in the National Herbarium of New South Wales, which is part of the Royal Botanic Gardens and Domain Trust Sydney and Office of Environment and Heritage. The Herbarium houses over 1.2 million other specimens.〔 The genus ''Persoonia'' was named after a South African botanist, Christiaan Hendrik Persoon (1761–1836, author abbreviation: Pers.) in 1798.〔 The specific name ''terminalis'' refers to the inflorescences (clusters of flowers) that, in this species, are at the ends of the branches.〔 It has been given the common name of Torrington geebung.〔 Within the genus, it is classified in the ''Lanceolata'' group, a group of 58 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. ''P.terminalis'' has been reported to interbreed with ''P.cornifolia'' and ''P.sericea''. Two subspecies are recognised: ''P.terminalis'' subspecies ''recurva'' has shorter, more recurved leaves reaching a maximum of in length, while ''P.terminalis'' subspecies ''terminalis'' has longer, straighter leaves measuring a maximum of long.〔 The former grows from Warialda in northern New South Wales north into Queensland and is rated as 3R on the ROTAP list, while the latter subspecies grows only in the vicinity of Torrington and is rated 2R on ROTAP.〔 Both subspecies have been found commonly near the Severn River Nature Preserve. 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 terminalis」の詳細全文を読む スポンサード リンク
