A perennial plant of the Cyperaceae family (APG classification: Cyperaceae). It grows to 0.5-1 meter tall and has leaves about 1 cm wide. It flowers in May-June, and the stigma of the female flower falls off after flowering. The sacs are dark green-brown and curl when ripe. It grows in marshes such as ponds and riverbanks, and grows in colonies on long rhizomes. The leaves that grow in summer are harvested and widely used to make umbrellas, raincoats, and ropes, and are therefore called kasage or minosuge. It is found throughout Japan, and is distributed in the Kuril Islands, Sakhalin, Korea, and China. A variant of kinki kasage, whose stigma does not fall off after flowering, is distributed in the Kinki and Chugoku regions. [Eiichiro Kinoshita July 19, 2019] It grows in wetlands such as ponds and riverbanks, and grows in colonies with long rhizomes. The long leaves are used to weave hats and raincoats.

カヤツリグサ科(APG分類:カヤツリグサ科)の多年草。高さは0.5~1メートルで、葉の幅は1センチメートル程度。花期は5~6月で、雌花の柱頭は花期後に脱落する。果胞は暗緑褐色で、熟すと反り返る。池や川岸などの湿地に生え、長い根茎を伸ばして群生する。夏に成長した葉を刈り取り、笠(かさ)や蓑(みの)、縄をつくるのに広く使われ、カサスゲやミノスゲという名がついた。日本各地にみられ、千島、樺太(からふと)(サハリン)、朝鮮、中国に分布する。近畿、中国地方には、花期後も柱頭が脱落しない変種キンキカサスゲが分布する。 [木下栄一郎 2019年7月19日] 池沼や川岸などの湿地に生え、長い根茎を伸ばして群生する。長く伸びた葉は、笠や蓑などを編むのに用いられた。別名ミノスゲ©Shogakukan 撮影/広瀬雅敏"> カサスゲ ©梅林正芳"> スゲのおもな種類(1)〔標本画〕 出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
