Abstract

Taxonomic treatment and the identification key for 6 species and 4 varieties from the genus Asarum (Aristolochiaceae) in Korea were presented on the basis of the morphological analyses. Recently the taxonomy of the genus Asarum in Korea is controversial in the definition of species and the establishment of variation range. Our morphological studies supported that the species A. patens, A. misandrum and A. versicolor should be recognized as independent species by the unique morphological characters such as calyx lobes, stylar protuberance and leaf variegation. Second, A. sieboldii var. cornutum, A. koreanum, A. maculatum and A. sonunsanense, regarded as species or variety by different scholars, showed a close relationship with A. sieboldii by the similar calyx characters. Thus, new combinations, such as A. sieboldii for. cornutum, A. sieboldii for. koreanum, A. sieboldii for. maculatum and A. sieboldii for. sonunsanense, are proposed. And A. heterotropoides var. seoulense and A. heterotropoides var. mandshuricum also had a close relationship, thus, new combinations, A. mandshuricum for. seoulense, A. mandshuricum for. mandshuricum, are proposed. Furthermore, it is appropriate that A. heterotropoides var. heterotropoides, only distributed in Japan, is revised into A. heterotropoides as independent species by the unique character from the 2 varieties above. Consequently, the genus Asarum in Korea is classified into 3 species and 7 forma.

한국산 족도리풀속(Asarum L.) 6종 4변종에 대한 외부 형태학적 연구를 수행하여 새로운 종 검색표를 작성하고, 분류학적 처리를 하였다. 금오족도리풀(A. patens), 각시족도리풀(A. misandrum), 무늬족도리풀(A. versicolor)은 꽃받침 열편의 형태, 화주돌기의 형태와 색, 잎의 모용과 무늬 등에서 다른 종들과 뚜렷이 구분되어 독립된 종임을 지지해 주었다. 여러 학자에 의해 종 또는 변종으로 기재되었던 뿔족도리풀(A. sieboldii var. cornutum), 자주족도리풀(A. koreanum), 개족도리풀(A. maculatum), 선운족도리풀(A. sonunsanense)은 꽃받침 열편이 자색이고 굴곡되는 등 족도리풀(A. sieboldii)과 매우 유사하여 A. sieboldii for. cornutum, A. sieboldii for. koreanum, A. sieboldii for. maculatum, A. sieboldii for. sonunsanense로 처리하였다. 또한 꽃받침 열편이 뒤로 젖혀지고 잎 이면에 털이 있어 형태적으로 매우 유사한 서울족도리풀(A. heterotropoides var. seoulense)과 만주족도리풀(A. heterotropoides var. mandshuricum)은 A. mandshuricum for. seoulense와 A. mandshuricum for. mandshuricum으로 학명을 정리하였으며, 일본에만 분포하는 A. heterotropoides var. heterotropoides는 독특한 꽃받침 열편의 형태 등을 가져 독립된 종인 A. heterotropoides로 취급하였다. 따라서 한국산 족도리풀속은 3종 7품종으로 재정리하였다.
