noun
alpine bistort; Bistorta vivipara
A perennial herbaceous plant found in alpine regions. The name literally means 'bulbil tiger's tail', referring to the small bulbils (むかご) that form on the flower spike.
高山でムカゴトラノオを見つけた。
I found an alpine bistort in the high mountains.
The name combines むかご (bulbil) and 虎の尾 (tiger's tail), describing the plant's appearance. The exact historical derivation is uncertain.
