Abstract

Floral structures of 11 korean lauraceous species belonging to six genera have been studied. Machilus is a primitive genus having relatively large bisexual flower, six tepals and staminodes in fourth whorl of stamen. The flowers of Nelitsea are highly reduced state as unisexual flower, six stames arranged to three whorls ans no staminode in the flower, so regared as more advanced group. Intrafamilial classification systems of Nakai (1939) and Pax (1891) are more reasonable but still have some discrepancies with results. The origin of tepals of this group has been a long controversial problem; whether the differentiation of tepals occur. Teratological study of Lindera erythrocarpa, inner tepals of this group must be originated from the staminode and outer tepals from leafy tepals. Although morphological differentiation does not sitll occur, inner and outer whorls of tepals are originated through different way.
