Abstract

A comparative micromorphology of petal and sepal of 15 species of Lycopus was undertaken to assess their usefulness in species identification and to evaluate their significance in the taxonomy using scanning electron microscope and stereo microscope. Five types of trichome are found within the genus: unicellular cylindrical trichome, unicellular trichome with papillae, simple multicellular trichome, capitate glandular trichome, and peltate glandular trichome. The types, distribution, and density of the trichomes show considerable variation among the taxa. The distributional pattern of the unicellular cylindrical trichomes on inner side of corolla is differed among the investigated taxa, and can be classified into four patterns. The apex shape of sepal and the incised position of calyx are also various and be recognizedas four patterns. The shape of cell composing in both outer and inner sides of petal and sepal are shown variously. Finally, the taxonomic significance of micromorphology of the petal and sepal in identification and elucidation of the genus Lycopus, especially among the species is also briefly discussed.

Lycopus속 15종의 화판(petal)과 악편(sepal)의 미세형태를 주사전자현미경과 실체현미경으로 관찰하여 그 분류학적 유용성을 검토하였다. Lycopus속 분류군들의 화관과 악에 분포하는 모용과 선모는 단세포 원주모(unicellular cylindrical trichome), 표면에 돌기가 있는 단세포 모용(unicellular trichome with papillae), 다세포 모용(simple multicellular trichome), 두상선모(capitate glandular trichome) 및 방패형 선모(peltate glandular trichome) 등 5 종류로 나타났으며, 모용의 종류, 분포, 밀도가 분류군마다 다르게 나타났다. 화관 안쪽면에 단세포 원주모(unicellular cylindrical trichome)의 분포 정도가 각 분류군마다 다르게 나타나, 그 분포 부위에 따라 4가지 유형으로 나눌 수 있었다. 악(calyx)은 악편이 갈라지는 정도와 악편 정단(apex)의 모양으로 4가지 형태로 구분할 수 있었다. 화판과 악편의 안쪽 빛 바깥면을 구성하는 세포의 형태는 그 위치와 분류군에 따라 다양하게 나타났다. 끝으로 관찰된 Lycopus속의 화판 및 악편 미세형태를 검토한 결과 종간 식별에 유용하였다.
