Scorzonera sinensis is delimited from S. austriaca largely by its undulate leaves, which it shares, however, with S. crispa M. Bieberstein (S. austriaca subsp. crispa (M. Bieberstein) Lipschitz & Krascheninnikov) from Crimea and Kazakhstan. According to Lipschitz (Fragm. Monogr. Scorzonera 1: 121. 1935; Fl. URSS 29: 68-69. 1964), it differs from the latter by basally more shortly attenuate, green rosette leaves and undivided stems with more numerous bracts. See also note under S. austriaca.
