トダシバ
校舎裏の道端にトダシバが咲いています。日当たりのよい草原などによく見られるイネ科の多年草です。和名は現在の埼玉県戸田市の荒川周辺に広がっていた戸田ヶ原に多く生えていたことに由来します。
"Toda-Shiba" plants are in bloom along the roadside behind the school building. They are perennial plants in the Poaceae family that are commonly found in sunny grasslands. Their Japanese name comes from "Toda-gahara", an area along the Arakawa River in present-day Toda city, Saitama prefecture, where these plants once grew abundantly.
