An annual plant of the family Poaceae (APG classification: Poaceae). It is entirely glabrous, with clustered, erect culms, 15-50 cm tall. In May-June, it produces cylindrical inflorescences at the end of the culm, with dense spikelets. The spikelets are flat on both sides, have one floret, and the glumes are larger than the glumes. The glumes are the same shape, bend inwards, and the upper end of the back protrudes. The Japanese name means "foxtail millet" because the shape of the spike resembles foxtail millet. It grows in the plains of Honshu, Shikoku, and Kyushu, and is widely distributed in China, Siberia, Europe, and the Mediterranean coast. The alpine plant Miyamaawagaeri P. alpinum L. and the pasture grass timothy (Ooawagaeri) are also in the same genus.
