A new species, Epilobium ulleungensis J. M. Chung (Onagraceae Juss), from Ulleungdo Island (South Korea) was described and illustrated. Among four taxa native to Ulleungdo Island (E. amurense Hausskn. subsp. cephalostigma (Hausskn.) C. J. Chen, Hock & P. H. Raven, E. hirsutum L., E. pyrricholophum Franch. Sav., and E. ulleungensis), E. ulleungensis has a unique tetragonal stigma, which is considered to be an intermediate form between clavate (E. pyrricholophum) or capitate (E. amurense subsp. cephalostigma) and 4-lobed stigmas (E. hirsutum). More importantly, this new species is clearly distinguished from the other three taxa distributed on Ulleungdo Island by its height (over 200 cm), decumbent stem, leaf shape, short, dense pubescent covering on the whole plant, large flower size, and a dark pink or red purple flower. According to the stigma shape and other characters, it was estimated that E. ulleungensis is a hybrid between E. hirsutum and E. pyrricholophum or E. amurense subsp. cephalostigma). The specific epithet "ulleungensis" was chosen because the new species was restricted to Ulleungdo Island.

Forty natural plants collected in Jeju, Jeonnam-Goheung, and Gyeongbuk-Ulleung were extracted using a pressurized liquid. Extraction yields of total soluble solids and total phenolics (TP), and integral antioxidative capacity (IAC) were measured, and antimicrobial activity was tested against Streptococcus parauberis, Streptococcus iniae, Edwardsiella tarda, and Vibrio ordalii. Jipsinnamul showed the highest content of TP (174.4 mg GAE/g), followed by Mulchamnamu (116.9), Seoeonamu (113.3), and Buknamu (108.2). Percent TP/TSS was high in Jipsinnamul (72.6%), Seoeonamu (47.3%), Mulchamnamu (46.4%), Jageumu (40.2%), and Baneulkkot (40.1%), respectively. Magamok, Nadosongipul, Buknamu, Mulchamnamu, and Seoeonamu showed 5.81, 3.96, 3.63, 3.63, and 3.34 mmol ascorbic acid equivalents/g of IAC of water-soluble substances, and Seoeonamu, Magamok, Seipijilpul, Mulchamnamu, Baneulkkot, and Seomgirincho showed 8.51, 6.57, 5.68, 3.85, 3.83, and 3.69 mmol Trolox equivalents/g of IAC of lipid-soluble substances, respectively. Only nine species such as Baneulkkot, Dokhwal, Jipsinnamul, Mulchamnamu, Nadosongipul, Seipijilpul, Seoeonamu, Seomgirincho, and Sumbadi of 40 selected plants showed the antimicrobial activity against four bacteria tested. Jipsinnamul showed the strong antimicrobial activity against S. iniae, while Dokhwal, Nadosongipul, and Sumbadi against S. parauberis and S. iniae, and Mulchamnamu, Seoeonamu, and Seipijilpul against V. ordalii.
