Abstract

Morphological and molecular data from the nuclear ribosomal ITS regions were examined to reevaluate the taxonomic position of the Korean endemic species, Stewartia koreana Nakai ex Rehder (Theaceae). Comparing to its morphologically closely related S. pseudocamellia Maxim, S. koreana has diagnostic characters including a larger leaf blade (10 cm length and 5.5 cm wide) and a longer pedicel (2.5 cm length). In addition, S. koreana formed a different clade from S. pseudocamellia in the ITS trees. The morphological and ITS sequence data supported S. koreana as a Korean endemic species distinct from the closely related species, S. pseudocamellia.

한국 특산종인 노각나무(Stewartia koreana Nakai ex Rehder)의 분류학적 위치를 재검토하기 위해, 노각나무와 근연 분류군의 외부형태와 ITS 염기서열을 조사하였다. 노각나무는 일본에 분포하는 S. pseudocamellia와 외부 형태적으로 매우 유사하였으나, 노각나무는 잎이 대형이고 소화경의 길이가 2.5 cm 이상인 점에서 S. pseudocamellia와 구별되었다. ITS 염기서열을 분석한 결과 노각나무는 S. pseudocamellia와 별개의 분계조를 형성하였다. 따라서 외부형태 및 ITS 염기서열 결과는 노각나무가 S. pseudocamellia와 다른 별개의 한국 특산종임을 지지해 주었다.
