Amanyu - Amanyu

Japanese: アマニュウ - あまにゅう
Amanyu - Amanyu

A large perennial herb of the Umbelliferae family (APG classification: Umbelliferae), which can reach a height of 2 meters. It grows in mountain grasslands. The leaves are compound, 1-2 times trifoliate, thin and hairless. The leaflets are large and broadly ovate, further divided into three, with sawtooth. The base of the petiole swells into a sheath. The flowers are white in number and appear in large compound umbels up to 20 cm in diameter in August. There are thin small bracts at the base of the pedicel. The fruit is elliptical, about 7 mm in diameter, with narrow wings on both sides. It is distributed in Hokkaido, Honshu (northern from the Chubu region and Mt. Daisen in Tottori Prefecture), and Shikoku (Mt. Ishizuchi). The stems are sweet and edible. Its name is "ama-nyu", and "nyu" is an Ainu word. The angelica tree is similar to this species, but differs in that it has hairy leaves and does not have bracts at the base of the stalk.
