''Chuquiraga'' is a genus of flowering plants in the aster family.〔(Jussieu, Antoine Laurent de. 1789. Genera Plantarum 178 ) in Latin〕〔 (''Chuquiraga'' Juss. ) ''Arboles y arbustos de los Andes del Ecuador''. eFloras.〕 The genus is distributed in the Andes from Colombia to Chile, with most species occurring in Patagonia.〔 These are evergreen shrubs. They have many shapes and sizes of leaves, and two general types of flowers apparently adapted for pollination by hummingbirds and insects.〔Ezcurra, C. (2002). (Phylogeny, morphology, and biogeography of ''Chuquiraga'', an Andean-Patagonian genus of Asteraceae-Barnadesioideae. ) ''The Botanical Review'' 68(1), 153-70.〕 Some species occur at elevations over 4000 meters in the Andes, while others can be found at sea level.〔Ezcurra, C., et al. (1997). (Phylogeny of ''Chuquiraga'' sect. ''Acanthophyllae'' (Asteraceae-Barnadesioideae), and the evolution of its leaf morphology in relation to climate. ) ''Systematic Botany'' 22(1), 151-63.〕 Many are of ecological importance because they are dominant plant species in very dry habitat types, and local animals depend on them.〔Hoeneisen, M., et al. (2000). (Constituents of ''Chuquiraga atacamensis'' and ''C. ulicina''. ) ''Boletín de la Sociedad Chilena de Química'' 45(1), 49-52.〕 Hummingbirds of the genus ''Oreotrochilus'', the hillstars, rely heavily on these plants, and some species have never been observed on any other plant taxa.〔Bleiweiss, R. (1982). (The northern limit of the hummingbird genus ''Oreotrochilus'' in South America. ) ''The Auk'' 99(2), 376-78.〕 Some species have been used as fuel, as traditional medicines, and as ornamental plants.〔 ;Species〔 ==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「Chuquiraga」の詳細全文を読む スポンサード リンク
