Abstract

Saussurea albifolia, a new species, is reported from the Baekdudaegan Mountains. It has distinctive morphological characteristics that distinguish it from other congeneric species of Saussurea in Korea; radical leaves persist or withered till flowering, white tomentose leaf beneath, campanulate involucre with browncobwebby hairs, and dark purplish phyllaries with acuminate tips. Saussurea albifolia is a new, endemic species, narrowly restricted to the Korean Peninsula as a consequence of adaptation to alpine or subalpine environments of the Baekdudaegan Area. Among the Korean species of Saussurea, S. gracilis Maxim., S. insularis Kitam., and S. seoulensis Nakai are morphologically similar to S. albifolia by having leaves with white hairs beneath and persistent radical leaves during blooming period. It has been well understood that Saussurea is one of the highly diversified and adaptable groups in Asteraceae and also that the currently recognized species in Korea likely significant underestimates its diversity on the Korean Peninsula.
