Abstract
Saussurea namhaedoana, a new endemic species narrowly restricted to Namhaedo Island of Korea, is reported in this study. It can be distinguished from other congeneric species of Saussurea in Korea by having persistent radical leaves until flowering, hastate or sagittate leaves with mucronate toothed to undulate-lobulate margins, grayish cobwebby hairs on abaxial leaf surfaces when young, and tubular involucre with grayish cobwebby hairs. Morphologically, S. namhaedoana is closely related to other species in Korea, such as S. gracilis Maxim., S. insularis Kitam., S. seoulensis Nakai and S. albifolia M. J. Nam and H. T. Im, sharing grayish or white hairs on the abaxial leaf surfaces. It, however, can be distinguished from its close relatives by having a distinct leaf shape, i.e., sagittate or hastate leaves. The phylogenetic relationship relative to congeners in East Asia is yet to be determined.
