Two Unrecorded species from Jeju Province are reported: Maesa japonica of Maesaceae which is unrecorded family and Cardamine tanakae of Brassicaceae. Monotypic family Maesaceae, is distinguished from Myrsinaceae and Primulaceae by having pedicels with a pair of bracteoles, flowers without staminodia, semi-inferior ovary and indehiscent fruits with many seeds. M. japonica is readily distinguishable from M. salicifolia in China and M. montana var. formosana in Taiwan and Japan by shapes of blades, corolla and bracteoles, the presence/absence of serrulation of leaf margins, ratio of length of corolla tube and corolla lobes, feature and color of fruit surface. C. tanakae is most similar to Korean endemic C. glechomifolia in morphology, however, the two taxa are readily distinguishable by the number of leaflets of cauline leaves, size of terminal leaflets, number of flowers per inflorescence, the presence of whitish hairs on ovary and fruits.
