Sparrowgrass - Sparrowgrass

Japanese: スズメノヒエ - すずめのひえ
Sparrowgrass - Sparrowgrass

A perennial grass of the family Poaceae (APG classification: Poaceae). It is covered with white pubescent hairs. The culm is clumpy and 40-90 cm tall. From August to October, it produces a raceme of 3-5 florets. The spikelets are on one side of the florets, are broadly elliptical, about 2.5 mm long, and contain two florets. The first glume is degenerate, while the second glume is hemispherically swollen. It grows in grasslands and is distributed from Honshu to Okinawa, Ogasawara, the Korean peninsula, and mainland China. It is named after the fact that it resembles barnyard millet, which is also a member of the Poaceae family, but its spikelets are smaller. It is distinguished as a different species, barnyard millet, when the leaves are hairless and the spikelets are densely attached to the florets.

Japanese:

イネ科(APG分類:イネ科)の多年草。全体が白い開出毛に覆われる。稈(かん)は株立ちし、高さ40~90センチメートル。8~10月、小花穂3~5本からなる総状花序をつける。小穂は小花穂の片側につき、広楕円(こうだえん)形で長さ約2.5ミリメートル、小花が2個ある。第1包穎(ほうえい)は退化し、第2包穎は半球状に膨らむ。草地に生え、本州から沖縄、小笠原(おがさわら)、および朝鮮半島、中国大陸に分布する。名は、同じくイネ科のヒエに似るが、小穂がそれより小さいことによる。葉に毛がなく、小穂が小花穂上に密につくものを、別種スズメノコビエとして区別する。
