Abstract

A morphological and molecular survey was conducted to determine the taxonomic status of Saussurea maximowiczii var. triceps on Jejudo Island. Although it tends to be smaller than S. maximowiczii with regard to typical quantitative characters of vegetative organs, including the plant height and leaf size, these two taxa cannot be distinguished from each other based on major reproductive characters, including the involucre and florets. Molecular data support the contention that S. triceps and S. maximowiczii are monophyletic taxa. Saussurea maximowiczii var. triceps is found to be an ecological phenotype of S. maximowiczii that has adapted particularly to the windy highlands of Hallasan Mountain on Jejudo Island.

한라분취(Saussurea maximowiczii var. triceps)의 분류학적 실체에 대해 형태 및 분자적 접근을 했다. 줄기 길이, 잎의 크기와 같은 영양기관의 정량형질에서 한라분취가 버들분취(S. maximowiczii Herd.)보다 작은 경향이 있으나, 이는 연속적 변이이다. 소화, 총포를 비롯한 생식기관 성질에서 한라분취와 버들분취는 구별할 수 없었다. 버들분취와 한라분취의 염기서열을 확인한 결과 이들은 단계통을 이루었다. 한라분취는 강풍에 면한 한라산 고산지대에 적응한 버들분취의 생태표현형으로 추정된다.
