The flora in the region of Mt. Sobaeksan National Park ($N36^{\circ}50^{\prime}-37^{\circ}50^{\prime}$, $E128^{\circ}20^{\prime}-128^{\circ}43^{\prime}$) was surveyed from April of 2005 to October of 2011. The vascular plants from 27 field surveys were revealed to total 869 taxa, comprising 112 families, 429 genera, 756 species, four subspecies, 91 varieties and 18 forms. Sixty-eight taxa were the first records from this region. This field study discovered significant plants in various categories. Korean endemic plants numbered 25 taxa, and 18 taxa designated by the Korean Forest Service as rare plants were investigated in this region. The taxa in category II of rare and endangered plants and higher than the third degree among the floristic regional indicator plants designated by the Korean Ministry of the Environment were three taxa and 75 taxa, respectively. From a geographical perspective, limited distribution of Saxifraga octopetala, Corydalis grandicalyx, Aegopodium alpestre, and Polygonatum acuminatifolium at a latitude higher than that of Sobaeksan National Park suggest that Sobaeksan National Park might be the limit line of the distribution of the taxa. Stewartia koreana demonstrate a reversed pattern from the taxa above, occurring at a latitude lower than that of Sobaeksan National Park. In addition, naturalized plants of 53 taxa were recorded.
