Kawarasugana - Kawarasugana

Japanese: カワラスガナ - かわらすがな
Kawarasugana - Kawarasugana

A perennial plant of the Cyperaceae family (APG classification: Cyperaceae). It grows to a height of about 30 cm, and produces inflorescences at the end of the stem from summer to autumn. The inflorescence is spherical with numerous spikelets densely packed together. The spikelets are about 1 cm long, and have reddish brown scales. Because the way the fruits grow is different, it is sometimes separated from the Cyperus genus as part of the Kawarasugana genus. It commonly grows in fields and wetlands throughout Japan, and is distributed as far as East Asia, Australia, and Africa. Its Japanese name is said to mean a grass that grows on riverbanks and resembles sedge.

Japanese:

カヤツリグサ科(APG分類:カヤツリグサ科)の多年草。高さは30センチメートルほどになり、夏から秋にかけて茎の先に花序をつける。花序は多数の小穂が密生して球形になる。小穂は長さ1センチメートルほどで、鱗片(りんぺん)は赤褐色になる。果実のつき方が異なるので、カワラスガナ属としてカヤツリグサ属から分けられることもある。日本各地の田畑や湿地に普通に生え、東アジア、オーストラリア、アフリカまで分布する。和名は、河原に生え、スゲに似た草の意味といわれる。
