Abstract

Saussurea grandicapitulata, a new species of Saussurea, was repodrted in the Taebaek Mountains. It has peculiar morphological characters, easily distinguisable from other Saussurea in Korea and Japan; robust plant size, pale green leaf beneath, purplish brown-cobwebby hairs on petioles of radical and lower cauline leaves, few heads with not so long pedicel, big globose involucres with brown-cobwebby hairs, and often recurved long phyllaries. S. grandicapitula is an endemic species to Korea which was differentiated in consequence of adaptation to heavy snowy environment of the Taebaek Mountains.

태백산맥에서 발견된 Saussurea속의 신식물을 태백취(S. grandicapitula)로 기재하였다. 우리나라 특산인 본 종은 크기가 70-100cm에 달하는 장대한 식물로, 잎 뒷면이 창백한 녹색이며, 적갈색의 얽힌 털이 엽병에 나고, 수개의 두화가 짧은 화경에 달리며, 구형의 커다란 총포에는 갈색의 얽힌 털이 밀생하고, 포편은 뒤로 젖혀지기도 하는 특징을 가져서, 한반도 북부나 일본의 다른 종들과는 명확히 구별된다. 이는 태백산맥의 눈 많은 환경에 적응 진화한 종으로 생각된다.
