This study reports on the morphological characteristics and distribution for conservation and practical use in the Korean Peninsula of Chrysosplenium flaviflorum through a comparison with relative species. The morphological characters that were newly investigated in this study included subhypogaeus stolons and glabrous on the surface of leaves. The former has not been described by any taxonomist who had previously treated this species with the exclusion of Hara. Despite this, the latter is a very important key to using the identification of varieties of Ser. Pilosa though there were no descriptions which included Ohwi. C. flaviflorum Ohwi which was endemic and known to be distributed only in the northern area of the Korean Peninsula, was also observed in the Gapyeong-gun, Gyeonggi-do, Cheorwon-gun, Gangwon-do, and Yeongdonggun, Chungcheongbuk-do middle area since the latest collection report in 1943. There is a requirement for further study to be conducted on the distribution and management by designation for the Special Plant Species by the Korean Ministry of Environment.

This study was carried out to illuminate the floras of vascular plants of Mt. Eungbongsan in Yeongwol-gun. This study was conducted from April to October, 2011. Based on the voucher specimens, vascular plants in this area consisted of 89 families, 288 genera, 405 species, 3 subspecies, 43 varieties, and 7 forms, totally 458 taxa. 16 species were endemic to Korea such as Cirsium setidens, Saussurea macrolepis, Salvia chanroenica, Anemone koraiensis, Clematis brachyura, Clematis trichotoma, Populus tomentiglandulosa, Salix dependens, Salix koriyanagi, Chrysosplenium flaviflorum, Philadelphus schrenckii, Lysimachia coreana, Lonicera subsessilis, Weigela subsessilis, Paulownia coreana, and Corydalis maculata. Ten taxa were rare plants as designated by Korea Forest Service such as Anemone koraiensis, Eranthis stellata, Aristolochia contorta, Rodgersia podophylla, Lysimachia coreana, Syringa wolfii, Lloydia triflora, Streptopus ovalis, Salvia chanroenica, and Carpinus tshonoskii. Plants specially designated by the Ministry of Environment in phytogeographic categories totaled 87 taxa including 39 taxa of grade I, 14 taxa of grade II, 19 taxa of grade III, 14 taxa of grade IV and 1 taxon grade V. Naturalized plants consisted of 8 families with 28 taxa that made up 6.1% of the total vascular plants in this area. Naturalized plants have not strongly influenced the Mt. Eungbongsan vegetation.
