''Circaea lutetiana'', known as enchanter's-nightshade, is a plant in the evening primrose family, Onagraceae. The genus name comes from the enchantress Circe of Greek mythology and the generic designation is derived from Lutetia, the Latin name for Paris. Paris at one time was known as the "Witch City". Despite its name it is not especially toxic, but contains a lot of the astringent tannin.〔(Alchemy Works ) Accessed April 2014〕 ==Description== ''Circaea lutetiana'' is a perennial herbaceous plant with opposite, simple leaves, on slender, green stems. The flowers are white, borne in summer. It grows 20 cm to 60 cm, rarely up to 75 centimeters high.〔(Natural England. ) Accessed July 2011〕 The leaves are rounded or slightly notched at the base, they narrow gradually to the pointed tip and are not strongly toothed, but have (sinuate ) edges. The leaf stalks are equally hairy all round.〔(English Country Garden ) Accessed July 2011〕 The flower has 2 notched petals, 2 stamens and a 2-lobed stigma. The open flowers are well spaced along the stalk and there are no bracts at base of individual flower stalks. The fruit consists of 2 equal cells, and usually sets seed. The flower stalks become angled downwards before fruiting.〔(Plant Identification UK ) Accessed July 2011〕 The fruit is a small bur 3.5-5mm〔 which aids the plant's dispersal via zoochory. In winter the aerial parts die off leaving an underground rhizome. 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「Circaea lutetiana」の詳細全文を読む スポンサード リンク
