Apparently all specimens of Parrya beketovii in the major Chinese herbaria were erroneously identified as other species. The occurrence of this species in China is here confirmed based on several collections, including Cheo Taiyien 650721 (IBSC, KUN, NAS, PE), Cheo Taiyien 651268 (KUN, PE), and Moysenko 35 (LE).
