Isodon inflexus, a perennial of 0.4-1m in height, occurs at the forest edges in fields and mountains. Leaves are opposite; the margins are coarsely serrated, in the shape of a broad oval, each 3-6cm in length, the base abruptly becoming narrow to follow the wing portion of the petioles. Blue-purple flowers, 7-9mm in size, bloom in slender spikes - upper lips cleft in four, lower lips make the shape of a boat. Bloom time: September-October.
