Naginata Koju - Naginata Koju

Japanese: ナギナタコウジュ - なぎなたこうじゅ
Naginata Koju - Naginata Koju

An annual plant of the Lamiaceae family (APG classification: Lamiaceae). The stem is square, 30-60 cm tall, sparsely hairy and branched. The leaves are opposite, narrowly ovate, with short stalks, and have a unique fragrance when crushed. From September to November, slender inflorescences form at the ends of the upper branches, and small, pale pink-purple flowers grow densely in one direction. The name comes from the resemblance of the inflorescence to that of a naginata (long sword). It grows on roadsides and grasslands in mountainous areas, and is widely distributed from the temperate zone of Asia to the Himalayas and the former Soviet Union. The closely related Myrtillus fasciatus has broad leaves and thick inflorescences, and is distributed in Honshu, Shikoku, and Kyushu south of Miyagi Prefecture.

Japanese:

シソ科(APG分類:シソ科)の一年草。茎は四角形で高さ30~60センチメートル、まばらに軟毛があって分枝する。葉は対生し、狭卵形で短い柄があり、もむと独特の香気がある。9~11月、上部の枝先に細長い花穂をつくり、小さな淡紅紫色花を一方向に密につける。名は、この花序の形が薙刀(なぎなた)の形に似ていることに由来する。山地の道端や草地に生え、アジアの温帯からヒマラヤ、旧ソ連地域に広く分布する。近縁のフトボナギナタコウジュは葉は広くて花序も太く、宮城県以南の本州、四国、九州に分布する。
