Discussion
Deutzia crenata and D. scabra are highly variable and have long been variously interpreted. A. J. Rehder (1920), assisted by H. O. Juel of Uppsala University, studied the three specimens at UPS that Thunberg had named D. scabra. He selected one as the type but said it was the same as the later-described D. crenata. J. Ohwi (1965) listed eight synonyms for D. scabra and interpreted D. crenata as consisting of three varieties, which included six synonyms (including “D. scabra Thunberg in part”). In view of the above, and the many cultivars that have been developed, D. crenata is treated here as a synonym of D. scabra.
