Following Li and Chen (FRPS 41: 148. 1995), one of us (Huang) retains Lespedeza stottsae (Gentes Herb. 1: 32. 1920), described from Jigong Shan, Henan, and L. dielsiana (Repert. Spec. Nov. Regni Veg. 10: 404. 1912), described from Sichuan, here in synonymy due to the lack of authentic specimens. Two of us (Ohashi and Nemoto) agree that these entities are conspecific with L. floribunda.
