セカンドオークヒルに、ミミナグサに混じってケミミナグサが咲いています。『神奈川県植物誌2018電子版』によると、ミミナグサよりもがく片が大きく、苞葉の縁が白膜質になるものをオオミミナグサといい、さらに腺毛をもつものをケミミナグサと呼ぶそうです。写真の個体は上記の特徴を満たすことから、ケミミナグサと判断しました。


"Ke-Mimi-Na-Gusa (ケミミナグサ)" plants are in bloom with "Mimi-Na-Gusa (ミミナグサ)" plants in the Second Oak Hill. According to "Flora of Kanagawa 2018 online version", the ones that have sepals larger than those of "Mimi-Na-Gusa (ミミナグサ)" and have white membrane-like margins on the bract leaves are called "Oo-Mimi-Na-Gusa (オオミミナグサ)". In addition, the ones that have glandular hair are called "Ke-Mimi-Na-Gusa (ケミミナグサ)". The one in the photo has the features mentioned above, so I identified it as the "Ke-Mimi-Na-Gusa (ケミミナグサ)".
