''Potentilla gracilis'', known as slender cinquefoil or graceful cinquefoil,〔Mackinnon/Pojar/Coupe. Plants of Northern British Columbia. BC Ministry of Forests and Lone Pine Publishing, 1992. ISBN 1-55105-015-3〕 is a species of cinquefoil. Named varieties are: * ''Potentilla gracilis'' var. ''elmeri'' (Rydb.) Jeps. – combleaf cinquefoil * ''Potentilla gracilis'' var. ''flabelliformis'' (Lehm.) Nutt. This perennial herb is variable in morphology, growing erect stems up to a meter tall from a branching caudex and rhizome unit. The leaves are palmate and compound,〔 each divided into five to seven wide lance-shaped leaflets with toothed edges. The leaflets are hairy, with many more hairs on the undersides, making them lighter in color than the top surfaces. The basal leaves are borne on very long petioles. Leaves higher on the stem are smaller and reduced. The inflorescence is a cyme of several flowers, each with usually five yellow petals. ==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「Potentilla gracilis」の詳細全文を読む スポンサード リンク
