초록
Prunus glandulosa Thunb. [=Cerasus glandulosa (Thunb.) Sokolov] (Rosaceae) is native to the warmtemperate region of China (Anhui, Fujian, Guangdong, Guangxi, Guizhou, Hebei, Henan, Jiangsu, Shaanxi, Shandong, Sichuan, Yunnan, and Zhejiang Provinces). It is naturalized in the United States (i.e. Alabama, Michigan and North Carolina) and Canada (Ontario). This species, previously only recorded as introduced or cultivated plants on the Korean Peninsula, was confirmed to be naturally distributed in the southwestern coast islands (i.e. Geomun-do, Chuja-do and an uninhabited island in Shinan-gun of Jeollanam-do). Prunus glandulosa Thunb. is distinguished from a related taxon P. japonica var. nakaii (H. Lév.) Rehder by pedicel 8-12 (-16) mm long, linear stipules, glabrous style, and pink petals. The morphological characters and illustration of P. glandulosa Thunb. are provided with line drawings and photographs from the natural habitat. In addition, it is likely that a new habitat will be found by plant biodiversity investigations through the southwestern coast islands. Further research is needed to determine its population size, distribution, and threats, as well as identify appropriate locations for conservation collection of germplasm.
