Yautia (English spelling)

Japanese: ヤウテア（英語表記）yautia

A perennial plant of the Araceae family cultivated in the tropics for its edible tubers and leaves. Native to the tropical regions of Central and South America and the West Indies, it is also called American taro. The leaves (blades) are arrowhead-shaped, acute triangles about 70 cm long, and long stalks (petioles) grow from the base, reaching a height of about 2 m. The stems do not grow long, but remain underground and swell to become tubers, with about 10 baby tubers growing around them. The baby tubers are 15 to 25 cm long. Because they resemble taro, they are sometimes called cocoyams without distinguishing between the two.

いもや葉を食用とするために，熱帯で栽培されるサトイモ科の多年草。中南米の熱帯地域，西インド諸島の原産で，アメリカサトイモともいう。葉(葉身)は矢じり形の鋭三角形で，長さ70cmほど，長い柄(葉柄)が根もとから伸び立って，草丈2mほどになる。茎は伸びず地中にあって肥大していもとなり，まわりに10個ほどの子いもをつける。子いもの長さは15～25cm。サトイモに似ているので両者を区別せずにココヤムcocoyamと呼ぶこともある。
