대사초(Carex siderosticta Hance)의 외부형태, 분포 및 대사초 절 내에서의 분류학적 위치 = Morphological Features, Distributional Status of Carex siderosticta Hance in South Korea and Its Taxonomic Position Within Sect. Siderostictae

다국어 초록 (Multilingual Abstract)

The taxonomic relationship of 3 taxa in Carex sect. Siderostictae were revealed by morphological and molecular studies. The morphological characteristics of Korean Carex siderosticta Hance, which is a type species of sect.
Siderostictae, was first reviewed in comparison with previous records in order to identify the difference. Then the distribution map of this species was formulated through previous floral literatures and voucher specimens. Although the leaf shape which is represented by length/width ratio showed a great variation depending on habitat condition, the rhizome creeping patterns, the presence of hair on the surface leaf margin and perigynium were shown to be good diagnostic characters to define delimitation of species level. The results from molecular study supported C. ciliatomarginata Nakai should be ranked independently on species level.

국문 초록 (Abstract)

국내에 분포하는 대사초절에 속하는 3분류군의 외부형태형질을 분석하고 분자계통학적 연구를 수행하여 이들 간의 유연관계를 밝혔다. 대사초절 내의 기본종인 대사초의외부형태학 특징을 재검토하여 기존 문헌과의 차이를 파악하였으며, 식물상 문헌 및 표본을 통해 국내 분포도를 작성하였다. 문헌에 언급된 형질들 중에서 잎의 형태는 생육지조건에 따라 변이가 심하였지만, 지하경 생장 양상, 잎과과낭의 털의 존재 등은 종수준에서 구분하는데 좋은 형질이었다. 분자계통학적 연구에서 털대사초는 독립된 종으로처리되는 것을 지지하였다.
