This species and the following three are clearly closely related. Tang (Acta Bot. Yunnan. 2: 439. 1980) likened S. salicifolia to S. pterosperma Maximowicz (Trudy Imp. S.-Peterburgsk. Bot. Sada 11: 67. 1889). We have not seen type material of S. pterosperma, but it is likely that that name applies to either S. hupehensis or S. salicifolia .
