• Two new combinations are proposed in Syringa L. (Oleaceae) based on examination of specimens, population sampling, and character analysis: S. tomentella Bureau & Franchet subsp. yunnanensis (Franchet) Jin Y. Chen & D. Y. Hong, and S. tomentella subsp. sweginzowii (Koehne & Lingelsheim) Jin Y. Chen & D. Y. Hong. Syringa wilsonii C. K. Schneider is treated as a synonym of S. tomentella subsp. sweginzowii. The lectotype of S. sweginzowii Koehne & Lingelsheim is designated.
