ナチシダ
ナチシダが見られます。常緑の大型のシダ植物で、葉は五角形に広がります。暖地性のシダで、静岡県河津町の自生地は1953年に自生北限地として国の天然記念物に指定されています。現在ではより北の自生地も知られており、キャンパス内でも徐々に個体数が増えているように思います。
"Nachisida (ナチシダ)" plants are found on campus. They are a large evergreen fern plant and spread their leaves in pentagon-shape. They prefer warm places. One of their habitats, Kawazu, Shizuoka, was designated as a national nature treasure in 1953 because it is regarded as "the northern limit of natural growth.” These days they are found further north and the number of them on campus seems to be gradually increasing.
