A new distribution record of Serissa serissoides (Rubiaceae) in Korea

We report a new distribution of Serissa serissoides (DC.) Druce on the Korean Peninsula. This species was initially reported in Jiangxi Province, China, and is distributed in Anhui, Fujian, Guangdong, Guangxi, Hubei, Jiangsu, Jiangxi, Zhejiang, and Taiwan. Recently, we found it in Jeollanam Province, South Korea. Serissa serissoides is readily distinguished from the only other species in the genus, S. japonica, by its inflorescence, flower, and fruit morphology. We provide a morphological description, photographs, and a key to related taxa. We give this species a new Korean name, Shin-an-baek-jeong-hwa, derived from the name of the area where it was found.
