Abstract

As a recent infrageneric classification of Juncus (Juncaceae), Kirschner suggested two subgenera which are distinguished by the type of inflorescence and the absence/presence of bracteole along with 10 sections which are distinguished by the characters of the leaves, the position of the inflorescence, and types of stamens and seeds. However, an intensive morphological investigation on Korean Juncus has yet to be performed. We surveyed the morphological characters of 14 taxa distributed throughout the Korean peninsula, including one North Korean taxon. The quantitative and qualitative characters of rhizomes, leaves, inflorescences, flowers, fruits, and seeds were investigated on each taxon using about 950 specimens of Korean Juncus on loan from major Korean herbaria. As a result, we provide diagnostic characters with illustrations and a key to Korean Juncus.

전 세계 Juncus (골풀속)의 속내 분류체계는 최근 Kirschner에 의해 2아속 10절로 정리된 바 있으며, 두 아속은 소포의 유무와 화서에 의해 구분되며, 각각의 절은 잎의 특징, 화서의 위치, 수술, 종자의 형질 등에 따라 구분된다. 현재까지 한국산 Juncus 분류군들을 구분하는 형질들에 대한 종합적 검토는 미흡한 상태이다. 그러므로 본 연구는 지금까지 한반도에 자생한다고 보고된 분류군들 중 채집 및 표본조사가 가능한 14개의 Juncus 분류군들에 대하여 국내 11개 표본관으로부터 약 950점의 표본을 대여하여 조사하였고, 이들에 대한 지하경, 잎, 화서, 꽃, 과실, 종자 등의 외부형태학적 형질들에 대한 형질상태의 유형을 파악하여 도해하고, 분류군들 간의 구분성을 검토하였다. 이를 바탕으로 주요 식별 형질들을 이용한 검색표를 제시하였다.
