The pentaploid Pteris × pseudosefuricola (2n = 145), a hybrid between P. cretica (apogamous 3x) and P. multifida (sexual 4x), was newly recorded from Shizuoka and Tochigi Prefectures, Japan. The pinnae are somewhat malformed with irregularly incised margins. The tips of veins in sterile pinnae often reach cartilaginous margins as in P. cretica, but sometimes end short of margins as in P. multifida.
