''Grevillea arenaria'' is a shrub which is endemic to the east of New South Wales in Australia. It has an erect to spreading habit and grows to between 1 and 3 metres in height. Its leaves are 1.5 to 7 cm long and 3 to 15 mm in width. The flowers, which occur in groups of 2 to 10, are pink, red or orange, with green or yellow at the base and green styles. These occur year round, with a major flourish in spring. The species was first formally described by botanist Robert Brown in ''Transactions of the Linnean Society of London'' in 1810. There are currently two recognised subspecies: * ''G. arenaria'' R.Br. subsp. ''arenaria'' * ''G. arenaria'' subsp. ''canescens'' (R.Br.) Olde & Marriott A former subspecies, known as ''G. arenaria'' subsp. montana (R.Br.) McGill., is currently treated as a species in its own right - ''G. montana'' R.Br. It occurs on sandy soils in open forests in the Great Dividing Range, its southernmost extent in line with Narooma and its northernmost extent in line with Sydney. ==References== * * 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「Grevillea arenaria」の詳細全文を読む スポンサード リンク
