''Pherosphaera fitzgeraldii'', commonly known as the Blue Mountains Pine or Dwarf Mountain Pine〔Thomas, P. 2013. (''Pherosphaera fitzgeraldii''. ) The IUCN Red List of Threatened Species. Version 2015.2. Downloaded on 03 September 2015.〕 is a species of conifer in the family Podocarpaceae. It is found only in New South Wales, Australia. The entire natural habitat is in the Blue Mountains, from Katoomba to Wentworth Falls, growing almost exclusively in the splash zones of waterfalls, and on the southern aspect of sandstone nearby. It was first described by Ferdinand von Mueller in his 1881 work ''Fragmenta Phytographiae Australiae'' as ''Dacrydium fitzgeraldii'', naming it after its collector, one R. Fitzgerald. It was renamed ''Microstrobos fitzgeraldii'' by Lawrie Johnson and Garden in 1951, and ''Pherosphaera fitzgeraldii'' by Joseph Dalton Hooker in 1882. ''Pherosphaera fitzgeraldii'' grows as a small shrub to 1 m (3 ft) high. The branchlets droop and bear tiny narrow leaves 2 or 3 mm in length.〔 Only 7 populations, containing a total of 455 individual plants are known. This conifer may be threatened by habitat loss, due to increased urbanization on the plateau. In the past hundred years, stream water quality has deteriorated, due to urban sprawl in the Blue Mountains. However, the population of ''Pherosphaera fitzgeraldii'' seems to have been stable over the last fifty years. ==Sources== 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「Pherosphaera fitzgeraldii」の詳細全文を読む スポンサード リンク
