Abstract
Two unrecorded naturalized species, Lolium rigidum Gaudin (Poaceae) and Oenothera rosea L'H$\acute{e}$r. ex Aiton (Onagraceae) were newly reported in Korea. L. rigidum, 'Daeng-Dol-Bo-Ri', was found at roadside of Yesong beach, Yesong-ri, Bogil-myeon, and roadside of Myeongsasimni beach, Sin-ri, Sinji-myeon, in Wando-gun, Jeollanam-do. It was distinguished from L. mutiflorum Lam by spikelet 10-20 mm long, florets 2-10(-13), and obtuse lemma, awn absent or up to 3-8(-10) mm. O. rosea, 'Ae-Ki-Bun-Hong-Nat-Dal-Mat-I-Kkot', was found in side of Wondong wetland, Yongdang-ri, Wondong-myeon, Yangsan-si, Gyeongsangnam-do. This taxon was distinguishable from other Oenothera in Korea by following combination of characters, stem erect to ascending, petal 5-12 mm long, pink to bright purple. Descriptions and illustrations of the two taxa and their photographs in the habitat are provided along with a key to the species of Lolium and Oenothera from Korea.
