Oxytropis anertii f. albiflora (Z. J. Zong & X. R. He) X. Y. Zhu & H. Ohashi; O. anertii var. albiflora Z. J. Zong & X. R. He.
Herbs, 6-8(-10) cm tall, acaulescent, from a well-developed multiheaded caudex, tufted. Branches with a thatch of marcescent leaves, with long trichomes when young. Stipules narrowly triangular, 5-13 × 2-5 mm, connate for more than basal half. Leaves 3.5-8 cm or 16-27 cm, 17-35-foliolate; leaflet blades ovate, 5-10 × 1-3 mm, subglabrous.
