''Prosartes'', the fairybells, is a North American genus of flowering plants in the lily family.〔 For several decades plants of this genus were considered part of the otherwise Asian genus ''Disporum''. Studies of morphology and cytology, as well as genetic analysis, show these North American plants to be different from the Asian species, and in 1995 the two groups began to be recognized as distinct genera.〔(Flora of North America: ''Prosartes'' )〕 ''Prosartes'' included five species until 2010, when a sixth, ''Prosartes parvifolia'', long considered a variant of ''Prosartes hookeri'', or perhaps a hybrid, was acknowledged as a distinct species.〔Mesler, M., et al. (2010). A resurrection for Siskiyou Bells, ''Prosartes parvifolia'' (Liliaceae), a rare Siskiyou Mountains endemic. ''Madroño'' 57:2 129-35.〕 These plants are rhizomatous herbs with bell-like pendent (hanging) flowers.〔 ;Species〔〔(Biota of North America Program 2014 county distribution maps )〕 *''Prosartes hookeri'' - drops of gold - California and Pacific Northwest, plus isolated populations in Black Hills and in the Upper Peninsula of Michigan *''Prosartes lanuginosa'' - yellow mandarin or fairybells - Appalachians, Ozarks, Ontario *''Prosartes maculata'' - spotted mandarin - southern Appalachians *''Prosartes parvifolia'' - Siskiyou bells - southwestern Oregon, northwestern California *''Prosartes smithii'' - largeflower fairybells - West Coast from Vancouver Island to San Francisco Bay *''Prosartes trachycarpa'' - roughfruit fairybells - western United States, central + western Canada ==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「Prosartes」の詳細全文を読む スポンサード リンク
