竹林にナチシダが見られます。ナチシダは五角形に広がる大型の葉が特徴の暖地性のシダです。静岡県河津町の自生地は1953年にナチシダの自生北限地として国の天然記念物に指定されています。近年では神奈川県などより北の自生地も知られており、不二聖心も実際の北限に近い自生地といえるかもしれません。


I found a "Nachishida (ナチシダ)" in a bamboo forest. "Nachishida (ナチシダ)" is a fern that has unique pentagon-shaped leaves and grows in warm climate. Their habitat, Kawazu, Shizuoka was designated as a national nature treasure in 1953 because it is regarded as "the northern limit of natural growth". However, recent years, we can see the plants in further north areas such as Kanagawa prefecture. It might be said that our campus is "the real northern limit of their natural growth".
