“…To accurately identify C. minus and provide morphological descriptions and a taxonomic key, we observed herbarium specimens by referring to related studies in the literature (Fernandes, 1971(Fernandes, , 1972Davis, 1978aDavis, , 1978bKuprianova, 1997;Rodríguez et al, 1997;Yildirim et al, 2010;Güemes et al, 2016;Zare et al, 2018;Kim et al, 2021;Rink, 2023;POWO, 2024). The external morphological characteristics of this species were observed using live and dried specimens collected from Dangjinsi.…”

“…Previously, Plantaginaceae only included the genus Plantago L. (Huisinga and Ayers, 1999). However, recent molecular phylogenetic studies have resulted in the inclusion of several genera from the Scrophulariaceae, such as Antirrhinum L., Digitalis L., and Linaria Mill., as well as the genera of Haloragaceae and Callitrichaceae in the Plantaginaceae (Albach et al, 2005;The Angiosperm Phylogeny Group, 2009;Güemes et al, 2016;Yousefi et al, 2016;Kim et al, 2021); thus, Plantaginaceae currently contains 94 genera of 12 tribes, with approximately 1900 taxa (Albach et al, 2005;Xu and Chang, 2017).…”

“…There has been no report of Chaenorhinum plants in the Republic of Korea, while there are five related genera in the same tribe, Antirrhinum, Cymbalaria Hill, Kickxia Dumort., Linaria, and Nuttallanthus D.A. Sutton (Kim et al, 2021;Korea National Arboretum 2024a, 2024b.…”

Chaenorhinum minus (L.) Lange of the family Plantaginaceae was discovered in Dangjin-si, Chungcheongnam-do, Republic of Korea. This species is an invasive alien plant that originated in Europe and North Africa and that was introduced into North America and East Asia. The genus Chaenorhinum (DC.) Rchb., to which this species belongs, is most similar to Nuttallanthus D. A. Sutton among related genera of the tribe Antirrhineae distributed in the Republic of Korea. While the two genera share common morphological features in the leaf and flower, Chaenorhinum is distinguished from Nuttallanthus by glandular hairs on the plant; monomorphic, fertile, and erect stems; 9.6–14.1 mm long pedicels; corolla as short as 5.6–7.9 mm; white corolla lower lips; and widely ovoid or oblong seeds. This study presents morphological descriptions and a genus key for the tribe Antirrhineae of the Republic of Korea for the identification of C. minus together with distribution information, voucher specimens, and photographs of this species.

Naturalized populations of two alien plants were newly found, and we describe their morphological characteristics and habitats with photographs. One is a member of Juncaceae, Juncus torreyi Coville, and was newly found at a pool of a beach in Gangwon-do. This rush is native to North America and belongs to the sect. Ozophyllum (subgen. Juncus) according to certain morphological characteristics, such as its racemose inflorescence, the absence of floral bracteole, and unitubular leaves with perfect septa. J. torreyi is easily distinguishable from Korean rushes by its long rhizomes with swollen nodes and globular head with 25–100 flowers. Its introduction into Japan and Europe was reported, but the ecological risk associated with its over-dispersal is not known. The other alien plant is a submerged plant, Egeria densa Planch. (Hydrocharitaceae), which was found in streams in Gyeongsangbuk-do and ditches in the Busan-si area, both of which being in the watershed of the Nakdong River. Egeria densa is similar to Hydrilla verticillata (L.f.) Royle, which is native to Korea. However, it is distinguished from H. verticillata by its larger flowers and lack of overwintering organs. This alien plant is native to South America and was introduced for aquarium gardening and naturalized around the world. Egeria densa is treated as a malignant weed due to its asexual reproduction and rapid growth. Size changes and the number of populations of E. densa must be investigated.
