In this paper, we report a newly recorded species, Orostachys japonica (Maxim.) A. Berger (Crassulaceae) from the Matsu Islands. It is also an unrecorded genus of Matsu. This species is distributed in Russia, China, South Korea, and Japan. It has been recorded in Anhui, Heilongjiang, Jiangsu, Shandong, and Zhejiang provinces in China. Although the Matsu Islands are closely adjacent to China, it has not been recorded there. In this report, we provide descriptions, line drawings, and colored photographs captured from the natural habitat for helping with identification.
