''Hakea'' (pincushion tree) is a genus of 149 species of shrubs and small trees in the Proteaceae, native to Australia. They are found throughout the country, with the highest species diversity being found in the south west of Western Australia. They can reach 1–6 m in height, and have spirally arranged leaves 2–20 cm long, simple or compound, sometimes (e.g. ''H. suaveolens'') with the leaflets thin cylindrical and rush-like. The flowers are produced in dense flowerheads of variable shape, globose to cylindrical, 3–10 cm long, with numerous small red, yellow, pink, purple, pale blue or white flowers. Hakeas are named after Baron Christian Ludwig von Hake, the 18th century German patron of botany, following Heinrich Schrader's description of ''Hakea teretifolia'' in 1797.〔Von Hake ( *1745-1818 *) was a Hanoverian official, among others serving as President of the ''Royal British and Electoral Brunswick-Lunenburgian Privy Council for the Duchies of Bremen and Verden'' in the years of 1800–1810.〕 It is now beginning to become accepted that ''Grevillea'' is paraphyletic with respect to ''Hakea''. It is likely, therefore, that ''Hakea'' may soon be transferred into ''Grevillea''. ==Classification== Hakeas are closely related to the genus ''Grevillea'' and ''Finschia'', both members of the subfamily Grevilleoideae within the family Proteaceae. Many species have similar inflorescences, but hakeas can be distinguished by their woody seed pods. 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「Hakea」の詳細全文を読む スポンサード リンク
