The caudex of ''D. mexicana'' is divided into regular polygonal plates that become protuberant with age, and separated by deep fissures. The vigorous annual vines which may reach 30 feet (9 m) long before dying back in winter, that grow up from the caudex, bear heart-shaped leaves.〔Dortort, Fred(2011). Succulent Plants of the World. Timber Press Inc. pp 220. ISBN 978-0-88192-995-9〕 ''Dioscorea mexicana'' ranges from the state of San Luis Potosí in northeastern Mexico south to Panama.〔Téllez V., O. & B. G. Schubert. 1994. 251.

Later the Mexican barbasco trade focused instead on ''Dioscorea composita'' instead, as this variety has a higher diosgenin content.〔(americanheritage.com )〕 ==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「Dioscorea mexicana」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.
