Abstract

Sisyrinchium micranthum Cav., a newly naturalized species, was found in Seogwipo, Jeju-do. This species is native to Central and South America and is reported as a widely invasive species around the world. Sisyrinchium micranthum is a sister species of S. rosulatum E. P. Bicknell (Deung-Sim-But-Kkot in Korean), reported as an invasive species earlier in Korea, and both species are members of the subgenus Echthronema. Sisyrinchium micranthum is distinguished from S. rosulatum by the urceolate shape of its flowers and by the large size of its fruits and seeds. Its local name is "Yeon-Deung-Sim-But-Kkot" based on the light blue corolla. We also found that Sisyrinchium angustifolium Mill., previously used for Deung-Sim-But-Kkot, was misapplied. It belongs to the subgenus Sisyrinchium and is morphologically very different from S. rosulatum. We corrected the scientific name of Deung-Sim-But-Kkot by changing it from S. angustifolium to S. rosulatum based on the type specimens, original descriptions, and recent studies.

제주도 서귀포시 일대에서 미기록 귀화식물 연등심붓꽃 (Sisyrinchium micranthum Cav.)이 발견되었다. 이 종은 중남미가 원산이며 여러 나라에서 침입종으로 보고된 바 있다. 연등심붓꽃은 국내에 먼저 보고된 귀화식물인 등심붓꽃의 자매종이며 두 종 모두 Echthronema 아속에 속한다. 연등심붓꽃은 화관의 밑부분이 긴 항아리 모양, 열매와 씨가 큰 점에 의해 등심붓꽃과 구별된다. 꽃이 연보라색이어서 국명을 연등심붓 꽃이라고 신칭하였다. 등심붓꽃의 이전 학명인 S. angustifolium Mill.은 Sisyrinchium 아속에 속하는 종이며 형태적으로 등심붓꽃 (S. rosulatum)과 매우 상이하다. 등심붓꽃의 학명을 기준표본, 원기재문, 최근의 논문들을 근거로 S. angustifolium Mill. 에서 S. rosulatum E. P. Bicknell 으로 변경한다.
