NEWCrop's online transcription of the 1930 USDA publication March 11, 1998. Accessed June 19, 2007.〕 The term "Pennyroyal" (or ''Pennyrile'', from a dialectal pronunciation) is also used to describe a geographic province of western Kentucky, the Pennyroyal Plateau, where ''H. pulegioides'' grew in profusion sufficient to lend its name to the whole area. ==Etymology== The name ''pulegioides'' is derived from the Latin ''pulegium'' and ''oides'', and means “like pennyroyal,” in reference to European pennyroyal (''Mentha pelugium'').〔Griffith, Chuck. (''Dictionary of Botanical Epithets'' ). Accessed June 19, 2007.〕 The name pelugium was given to European pennyroyal by Pliny the Elder in the first century CE, for its use in repelling ''pulex'' or ''pulices'' (Latin for fleas) by spreading it on floors.〔 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「Hedeoma pulegioides」の詳細全文を読む スポンサード リンク
