Green foxtail - Enokorogusa

Japanese: エノコログサ - えのころぐさ
Green foxtail - Enokorogusa

An annual weed of the grass family (APG classification: Poaceae). Also called cat hawkweed. The culms are sparse and 20-70 cm tall. The edges of the leaf sheaths are hairy. From August to October, the plant produces cylindrical inflorescences 2-5 cm long at the top, pale green or purple, with hairs on the central axis. The spikelets are about 2 mm long. The fourth glume has unclear horizontal wrinkles, tiny dots, and is surrounded by the second glume. It is commonly found in wastelands and fields throughout Japan, and is widely distributed in Asia. It is considered to be the original species of foxtail millet. It was named after the inflorescence, which resembles the tail of a small dog. The variety Hamaenocoro that grows on the coast and has short inflorescences is called Hamaenocoro. A similar species is the autumn foxtail, which has spikelets 3 mm long and an exposed fourth lemma. The golden foxtail has hairless leaf sheaths, horizontal wrinkles in the fourth lemma, and slightly larger spikelets, about 3 mm long.

Japanese:

イネ科(APG分類:イネ科)の一年生雑草。一名ネコジャラシ。稈(かん)はまばらに株立ちして高さ20~70センチメートル。葉鞘(ようしょう)の縁(へり)に軟毛がある。8~10月、頂部に長さ2~5センチメートルの円柱形の花序を出し、淡緑色または紫色で中軸に毛がある。小穂は長さ約2ミリメートル。第4穎(えい)は横しわが不明瞭(ふめいりょう)で、微小な点をもち、第2包穎に包まれる。日本全土の荒れ地や畑に普通に生え、アジアに広く分布する。アワの原種とみなされている。名は、花穂が狗(えのこ)(小犬)の尾に似ているためつけられた。海岸に生えて花穂が短いものを変種ハマエノコロという。似た種類に、小穂が3ミリメートルあって第4穎が露出するアキノエノコログサがある。またキンエノコロには葉鞘の縁に毛がなく、第4穎に横しわをもち、小穂は多少大きく、長さ約3ミリメートルである。
