In this study, we investigated the flora of Jeonggwangsan Mt. (Yongin, Korea) from May of 2015 to September of 2016. Through 14 independent field investigations, we identified a total of 367 taxa of vascular plants, including 89 families, 234 genera, 323 species, six subspecies, 34 varieties, and four formae. Eight taxa were endemic to Korea, while 27 were naturalized in Korea. Nineteen taxa were the floristic regional indicator plants in Korea: four in Rank VI, four in Rank III, two in Rank II, and nine in Rank I. A total of 59 taxa were designated as controlled Korean biological resources, requiring special permission for export to outside countries. Two taxa were listed on the Red List of Korea, including one Near Threatened (NT) taxon (Hololeion maximowiczii Kitam.) and one Least Concern (LC) taxon (Iris minutoaurea Makino).
