부추속(부추과)의 두 신분류군: 돌부추, 둥근산부추 = Two new taxa of Allium (Alliaceae) from Korea: A. koreanum H.J. Choi et B.U. Oh and A. thunbergii var. teretifolium H.J. Choi et B.U. Oh

다국어 초록 (Multilingual Abstract)

Here we described and illustrated two new taxa of Allium (Alliaceae) from southern part of Korea. One new species, A. koreanum H.J. Choi et B.U. Oh was clearly distinguished from A. splendens of sect. Reticulato-bulbosa by larger and stellately spreading pale pink perianth, apparently exsert filaments, and conical stigma as well as chromosome number. Another new variety, A. thunbergii var. teretifolium H.J. Choi et B.U. Oh was also easily distinguished from its relatives, var. thunbergii and var. deltoides by terete and hollow leaf blade. Keys to the two species of Allium sect. Reticulato-bulbosa and the three varieties of A. thunbergii in Korea were provided.

국문 초록 (Abstract)

한국의 남부지방에서 발견된 부추속(부추과)의 새로운 두 분류군을 기재 및 도해하였다. 신종으로 처리된 돌부추(A. koreanum H.J. Choi et B.U. Oh)는 크기가 보다 크며, 별모양으로 완전히 벌어진 옅은 분홍색의 화피, 현저하게 돌출된 화사, 그리고 원추형의 주두 및 염색체수의 특징으로 동북아시아에 널리 분포하는 돌부추절(sect. Reticulato-bulbosa)의 가는산부추(A. splendens)와 명확히 구분되었다. 또한 신변종으로 처리된 둥근산부추(A. thunbergii var. teretifolium H.J. Choi et B.U. Oh)는 원통형의 속이 비어있는 엽신 등의 특징으로 근연인 산부추(var. thunbergii) 및 세모산부추(var. deltoides)와 쉽게 구별되었다. 한국산 돌부추절의 두 종과 산부추의 세 변종에 대한 검색표를 제시하였다.
