Abstract

We report a previously unrecorded woody species, Stachyurus praecox Siebold & Zucc. (Stachyuraceae), in Korea. This species is considered to be endemic to Japan. Stachyurus praecox was collected for the first time in an evergreen forest on an uninhabited island of Bongsun-ri, Saengil-myeon, Wando-gun, Jeollanam-do in Korea. The inflorescence of the species was racemose and pendulous on the axils of the previous year's branches. Flowers bloomed from March to April. They were functionally dioecy but morphologically hermaphrodite. This woody species was named 'Wan-do-sul-kkot-na-mu' in Korean based on the shape of its inflorescence. Morphological characteristics and illustrations of this woody species have been provided with a distribution map and photographs of the natural habitat.

전남 완도군 섬지역에서 발견된 Stachyurus praecox Siebold & Zucc.를 우리나라 미기록 식물로 보고한다. 이 수종은 일본의 난·온대지역에 넓게 분포하고 있으며, 특산수종으로 알려져 왔다. 꽃은 총상화서에 달리며, 형태적으로는 양성화지만, 기능적으로는 자웅이주로 관찰되었다. 화관은 흰색 또는 연한 보라색 꽃잎과 꽃받침은 각각 4개이다. 국명은 최초 발견지 지역명과 꽃차례 모양이 장식용으로 달리는 여러 가닥의 실을 의미하는 뜻으로 쓰이는 "술"을 고려하여 "완도술꽃나무"로 신칭하였으며, 이에 대한 기재문과 도해, 사진을 제시하였다.
