Taxonomic identities of Utricularia japonica and U. tenuicaulis were examined. Utricularia japonica was differed from U. tenuicaulis by having a scape narrower than the stem, rather sparsely arranged leaves, and more or less oblong leaves. Utricularia japonica has been known to occur widely in Korea due to the misidentification of U. tenuicaulis, which is distributed widely in southern and middle Korea. However, only one population of U. japonica was found in Chunjin Lake, near Kosung-gun, Kwangwon-Do, in Korea.

Six taxa described by Miki were lectotypified using the specimens deposited in OSA; Myriophyllum oguraense, Najas oguraensis, Najas tenuicaulis, Ruppia truncatifolia, Utricularia minor var. multispinosa and U. tenuicaulis.

Specimens donated by the late Dr. Miki, deposited in the Osaka Museum of Natural History (OSA), were examined. Among about 3,6000 specimens, 104 specimens consisting 48 taxa were from Korea. These were collected by 14 collectors, including Dr. Miki and Hyung-Doo Chang. Taxonomic comments on Korean aquatic vascular plants collection were made, especially on Ranunculus kadzusensis, Potamogeton pectinatus, Zostera japonica, Ruppia truncatifolia, and the Utricularia species, including the three unrecorded species from Korea.

The Ramsar protected area in Ungok wetland, which has been designated since 2011, was described by syntaxonomy and synchorology. Phytocoenon was identified and named by a traditional method of the $Z{\ddot{u}}rich$-Montpellier School and Code of Phytosociological Nomenclature. Habitat-based vegetation classification has identified into twelve syntaxa consisting of 88 taxa in seven vegetation types: Juncus effusus var. decipiens-Salix koreensis community, Caricis-Salicetum subfragilis, Galium spurium var. echinospermon-Phragmites japonica community, Phragmitetum australis, Scirpetum fluviatilis, Leersia japonica-Typha angustifolia community, Juncus diastrophanthus-Juncus effusus var. decipiens community, Leersicetum japonicae, Nymphoido indicae-Trapetum japonicae (typicum, marsiletosum quadrifoliae subass. nova hoc loco, variante Euryale ferox), Nelumbo nucifera community, Utricularia tenuicaulis community, Potamogetonetum crispi. Actual vegetation map was made by using topographical map of scale 1 : 5,000. Habitat-based management on the Ungok wetland vegetation was required, in which there are composed of two major areas such as the back-swamp vegetation and the limnetic vegetation zone.
