It is native to much of North America, including the southern half of Canada and most of the United States. It is aquatic or semi-aquatic, growing in water or in or near muddy areas in many habitat types. It is a perennial herb that produces stems up to about 70 centimeters long that float in water or spread along wet ground, sometimes rooting where they come in contact with moist substrate. Leaves are variable in morphology; as in many types of aquatic plants, leaves that develop submerged in water look different from those that develop in air. This phenomenon, heterophylly, has been studied extensively in this species, and leaf morphology has been shown to be influenced by many environmental factors, including temperature〔Johnson, M. P. (1967). (Temperature dependent leaf morphogenesis in ''Ranunculus flabellaris''. ) ''Nature'' 214, 1354-55. doi = 10.1038/2141354a0〕 and the concentration of abscisic acid.〔Young, J. P., et al. (1990). (Heterophylly in ''Ranunculus flabellaris'': the effect of abscisic acid on leaf ultrastructure. ) ''Ann. Bot'' 65, 603-15.〕 A number of other factors affect leaf shape in heterophyllous plants.〔Young, J. P., et al. (1995). (A morphometric analysis of heterophyllous leaf development in ''Ranunculus flabellaris''. ) ''International Journal of Plant Sciences'' 156(5), 590-602.〕 In this species, leaves that develop in the open air have somewhat rounded blades that are divided into a number of short, blunt, wide lobes. Leaves that develop underwater have narrow, even threadlike lobes. The inflorescence is made up of one or more flowers with five to fourteen, but generally no more than eight, shiny yellow petals. The petals, each up to 1.3 centimeters in length are arranged around a central nectary with many stamens and pistils. The fruit is an achene borne in a dense cluster. ==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「Ranunculus flabellaris」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
