Japanese name: チヂミザサ（縮笹） Scientific name:Oplismenus undulatifolius
[Overview]
A perennial 10–30 cm tall, found in places such as woodland.
The culm (stem) is slender, and the base creeps along the ground for a long distance and branches.
The leaves are alternate simple leaves, broadly lanceolate, 3–7 cm long and 1–1.5 cm wide, and wavy.
Both sides of the leaves are hairy.
The leaf base forms a sheath that clasps the stem, and the margin of the sheath is hairy.
The inflorescence is 6–12 cm long and erect; it has 6–10 branches that do not elongate but remain short and densely bear spikelets.
The spikelets are about 0.3 cm long, consist of 2 florets, and are sparsely hairy.
The first glume has a long awn.
When the fruit ripens, the awns of the glumes secrete a sticky fluid, and the fruits are dispersed by sticking to animals and other things.
[Notes]
The Japanese name comes from the leaves resembling those of sasa (dwarf bamboo) and having crinkled margins.
