A perennial plant of the Lamiaceae family (APG classification: Lamiaceae) that grows on roadsides in mountains and fields. The stem is square, 30-80 cm tall, and branches at the top. The leaves are opposite and petiolar, and vary from simple to trifoliate, bipinnate. From July to October, long inflorescences are produced at the ends of the branches, and several pale purple flowers are produced in multiple tiers that open from the bottom. The calyx is tubular, divided into two lips, and has a ring-like hair on the inside. The corolla is a tube about 10 mm long, divided into two lips at the end. The two stamens protrude beyond the tip of the corolla and bend downward after pollination. There is a ring-like hair near the base of the inner surface of the flower tube. Distributed from Honshu to Okinawa Prefecture, Korea, Taiwan, and China. Closely related species include Natsunotamurasou and Harunotamurasou.
