The Gochnatioideae are a subfamily of the aster family, Asteraceae. It contains the single tribe Gochnatieae.〔Panero, J. L. and V. A. Funk. (2008). (The value of sampling anomalous taxa in phylogenetic studies: major clades of the Asteraceae revealed. ) ''Molecular Phylogenetics and Evolution'' 47(2), 757-82.〕 There are six genera,〔Tellería, M. C., et al. (2013).

(2007). (Classification, diversity, and distribution of Chilean Asteraceae: implications for biogeography and conservation. ) ''Diversity and Distributions'' 13(6), 818-28.〕 with a total of about 80〔 to 90〔 species. They are native to the Americas from the southern United States to Argentina, including the Caribbean, and Cuba in particular.〔Funk, V. A., et al. (Classification of Compositae. ) In: Funk, V. A., et al (eds.) ''Systematics, Evolution, and Biogeography of Compositae''. Vienna: IAPT. 2009. Pp. 171-89.〕 These are trees, shrubs, subshrubs, and perennial herbs. They have alternately arranged leaves and some have basal rosettes. The inflorescence is a solitary flower head or a few or many. Some only have disc florets, and some also have ray florets. The heads are small, with just a few florets, or large, with hundreds. They are usually white to orange, but some species have pink or purple florets. The disc florets are tubular with deep lobes at the tips.〔 Genera include:〔 *''Anastraphia'' *''Cnicothamnus'' *''Cyclolepis'' *''Gochnatia'' *''Pentaphorus'' *''Richterago'' ==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「Gochnatioideae」の詳細全文を読む スポンサード リンク
