Abstract: The alien plant Hedypnois rhagadioloides (L.) F. W. Schmidt was found at Busan New Port. The genus Hedypnois Mill, to which this species belongs, is a new record in the flora of the Republic of Korea; it is related to the genera Hypochaeris L. and Picris L. Hedypnois but can be distinctly distinguished from these two genera by its pappus, which consists of scale-like bristles. Additionally, during fruiting, plants of this genus exhibit an inflated and ridged peduncle, and its inner phyllaries become hardened, curved, and envelop the outer cypselae. The cypselae have shallow longitudinal ridges and scales on their surface. This study provides photographs of H. rhagadioloides along with descriptions of the genus and species, as well as identification keys based on morphological research.
