The presnt work was commenced for the purpose of getting more accurate information in this field. As a result of the investion, fourteen families, twenty-eight genera and thirty-eight species were recorded for these islets. Among these thirty-two species occurred in Zamami (abbreviated Z in the list) and twenty-three in Yakabi (Y). The list of ferns on the islets has been based mainly on the author's collection (K. S.) in the Herbarium of the University of the Ryukyus. The following species are new additions to the flora of the Kerama Islands, Okinawa. Marsilea crenata Presl (Z) Ophioglossum petiolatum Hook. (Y) Lindsaea heterophylla Dry. (Z) Lindsaea tenera var. commixta (Tagawa) K. Iwatsuki (Z, ?Y) Nephrolepis hirsutula (Forst.)
