Abstract

Two new species of Peucedanum (Apiaceae), P. miroense and P. tongkangense, from Gangwon Province, South Korea, are described. Both species are most similar to P. elegans and P. hakuunense because of their linear ultimate leaf segments. Peucedanum miroense was found on crevices of rocks in mountain summits and can be distinguished by its pubescent ovary, purple anthers, oblong schizocarp, and 1 or (2) vittae per vallecula and 4 on the commissural face. Peucedanum tongkangense was found in open areas on rocky cliffs along the Donggang River and can be distinguished by its glabrous ovary, whitish-yellow anthers, narrowly ellipsoid schizocarp, and 3 vittae per vallecula and 4 on the commissural face. Distinguishing characteristics, full descriptions, illustrations, photographs, taxonomic notes on geographical distribution, ecology, and phenology of the two species are presented. An identification key for all Korean species of Peucedanum is also provided. In addition, the mericarp surface of two new species and their close relatives are compared using micromorphological analysis.
