Abstract

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.

제주도에서 한국 미기록과인 빌레나무과 (Maesaceae)의 빌레나무 (Maesa japonica)와 십자화과의 꼬마냉이 (Cardamine tanakae)가 채집되었다. 빌레나무과는 Maesa, 1 속으로 구성된 과로서 소화경에 한 쌍의 소포엽이 있으며, 가웅예가 없고, 준자방하위이며, 다수의 종자를 갖는 폐과인 점 등으로 자금우과와 앵초과 식물과 구별된다. 빌레나무는 엽신, 화관 및 소포엽의 형태, 엽연부의 거치의 유무, 화통과 화관열편의 길이의 비율, 과실 표면의 특성 및 색깔에 의해 각각 중국, 대만 및 일본에 분포하는 M. salicifolia와 M. montana var. formosana와 뚜렷하게 구별되었다. 꼬마냉이는 경생엽의 소엽 수 및 정소엽의 크기, 한 화서에 붙는 꽃의 수, 자방 및 열매의 백색 연모의 유무의 특징에 의해 국내 고유종인 벌깨냉이 (C. glechomifolia)와 명백히 구분되었다.
