Horaninovia minor Schrenk (in Fischer & C. A. Meyer, Enum. Pl. Nov. 1: 11. 1841) has been reported from Xinjiang (Tacheng) by Grubov (Rast. Tsentral. Azii 2: 100. 1966), based on a specimen collected in 1840 by Schrenk “near Chuguchak” and preserved at LE. No specimen has been seen by the present authors. It differs from H. ulicina in having leaves and bracts arcuate curved, perianth wingless, and anthers with a linear appendage.
