Taro (Colocasia antiquorum var. esculenta) - Taro (English spelling)

Japanese: サトイモ(里芋) - サトイモ（英語表記）Colocasia antiquorum var. esculenta

A perennial plant of the Araceae family, native to tropical Asia. It is an important crop cultivated widely from the tropics to temperate regions. Numerous leaves grow from a short, thick underground rhizome, with thick, porous, soft petioles that overlap at the base. The leaf blades are heart-shaped and oval, and secrete wax onto the surface to repel water. Around October, it occasionally produces spadixes wrapped in yellow-green spathes. As it grows, it produces many baby tubers on the sides of the parent tuber. The tubers contain starch and carbohydrates. There are many cultivated varieties, and the group known as taro in tropical Asia is also a variety of this species.

サトイモ科の多年草で，熱帯アジア原産。熱帯から温帯地方にかけて広く栽培される重要な作物。地下の太く短い根茎から多数の葉を出し，葉柄は太く多孔質で軟らかく，基部は互いに重なり合っている。葉身は心臓形をした卵形で表面にろう質を分泌して水をはじく。 10月頃，まれに黄緑色の仏炎包に包まれた肉穂花序をつける。生育するに従って親芋の側方に多数の子芋を生じる。芋はデンプンや炭水化物を含む。栽培品種は非常に多く，熱帯アジアでタロイモ taroと呼ばれている一群もこのサトイモの品種群である。
