21FDD01411EA56D6B55BE2AC8AA05AEB.taxon	distribution	Distribution and ecology. Peucedanum miroense is restricted to only two populations on the summits of Swinŭm-san and Duta-san at Miro-myeon, Samcheok-si, Gangwon Province, South Korea. The two populations are connected to each other. The plants occur in rocky areas at the top of the mountains at an elevation of 540 - 680 m (Fig. 5). One population, at the type locality on Swinŭm-san, was growing with Allium thunbergii G. Don (Amaryllidaceae), Dendranthema boreale (Makino) Y. Ling ex Kitam. (Asteraceae), Fraxinus sieboldiana Blume (Oleaceae), Lespedeza bicolor Turcz., L. maximowiczii C. K. Schneid. (Fabaceae), Peucedanum terebinthaceum (Fischer ex Trevir.) Turcz. (Apiaceae), Pinus densiflora Siebold & Zucc. (Pinaceae), Quercus mongolica Fisch. ex Turcz (Fagaceae), Rhododendron mucronulatum Turcz. (Ericaceae), Sedum polytrichoides Hemsl. (Crassulaceae), and Spodiopogon sibiricus Trin. (Poaceae). The other population of P. miroense on Duta-san was growing with Aconogonon microcarpum (Kitag.) H. Hara (Polygonaceae), Chrysanthemum zawadskii Herbich (Asteraceae), and Geranium koreanum Kom. (Geraniaceae). Each population of P. miroense comprised approximately 120 individuals.	en	Kim, Kyeonghee, Suh, Hwa-Jung, Song, Jun-Ho (2022): Two new endemic species, Peucedanum miroense and P. tongkangense (Apiaceae), from Korea.
