한국산 광의의 고랭이속(사초과)의 분류학적 연구 I. 매자기속, 큰고랭이속, 올챙이골속, 고랭이속, 애기황새풀속의 형태적 특성 = Taxonomic study of Korean Scirpus L. s.l. (Cyperaceae) I. Morphology of Bolboschoenus (Asch.) Palla, Schoenoplectus (Rchb.) Palla, Schoenoplectiella Lye, Scirpus L., and Trichophorum Pers.

다국어 초록 (Multilingual Abstract)

Scirpus L. s.l. of Cyperaceae has been regarded as a monophyletic group, but the taxa of Scirpus s.l. were rearranged into the five independent genera in recent molecular phylogenetic research: Bolboschoenus (Asch.) Palla, Schoenoplectus (Rchb.) Palla, Schoenoplectiella Lye, Scirpus L., and Trichophorum Pers. In this study, we examined the morphological characteristics and presented the delineation of the five genera of Scirpus s.l.,including 21 taxa from South Korea. As a result of our investigation and analysis of domestic collections and those from abroad, the each taxon could be identified using key characteristics of the rhizome features; a cross-section of culm; the degree of development and the width of leaves; the shapes of the membranous region of leaf sheath; and the shapes and size of inflorescence, bract, floral scale, and achene. These major characteristics are illustrated and artificial keys are suggested in this study. In addition, we suggest a new combination for an unrecorded taxon of Schoenoplectiella that was discovered in Gangwon-do, Goseong-gun and give it the Korean name, as ‘Na-do-song-i-go-raeng-i’.

국문 초록 (Abstract)

사초과에 속하는 광의의 고랭이속(Scirpus L. s.l.)은 단계통으로 취급되어 왔으나 최근의 분자 계통학적인 검토 결과에 의하여 서로 독립된 다섯 개의 속(매자기속, 큰고랭이속, 올챙이골속, 고랭이속, 애기황새풀속)으로 재배치되었다. 본 연구에서는 광의의 고랭이속으로 취급된 우리나라의 다섯 개 속과 이에 딸려있는 21분류군을 대상으로 각 분류군의 형태적인 식별형질을 조사하고 각 분류군들의 한계를 제시하였다. 국내외에서 채집된 표본을 조사 분석한 결과 각 분류군들은 지하경의 형태, 줄기의 단면, 잎의 발달 정도와 너비, 엽초 막질부위의 형태, 화서, 포, 인편 및 수과의 형태와 크기로 식별이 가능하였다. 이에 대한 주요 형질을 도해하였고, 이를 바탕으로 각 분류군에 대한 검색표를 제시하였다. 또한 강원도 고성군에서 발견된 올챙이골속의 미기록 분류군에 대하여는 신조합명을 부여하고 ‘나도송이고랭이’로 국명 신칭하였다.
