They are a perennial plant that ordinarily grows at the woodland paths and the roadside in the countryside (Perennial plant takes several years to grow). The thin stalk gets split over and over again to expand creeping on the ground, and the top upstands. The leaf is thin and long elliptically-shaped, about 3 to 7 cm long, about 1 to 1.5 cm wide with the sharp top and also the root portion attaching like holding the stalk. The reason for their name is that the shape of the leaf looks like bamboo grass and that the leaves get wrinkled at the edge as if they crispate. This is why they are named ‘Oplismenus undulatifoliu’ (Chizimizasa). They grow Scape (Kakei: the stem with only flowers and no leaves) about 10 to 15 cm from the top of the stem, and then develop 6 to 10 of short branches with some white dense spikelet (Shosui: a part of plant) in cluster. Spikelet is thin egged-shaped about 3 mm long, has an acerate protruding object called ‘awn’ (Nogi), which is typical among the group of Gramineae. When the matured seeds are easy to get off from spikelet (Shosui), and they excrete a sticky liquid from awn (Nogi), so that they can be attached to animals and human being on the clothes to be carried.
