The new species is similar to A. lubae Aver. et Tillich in the perianth shape, but differs by the creeping rhizome, externally yellowish white perianths with internall yellow lobes, and the flat, glabrous stigma.The new species is also similar to A. nankunshanensis Yan Liu & C. R. Lin in the ovate-triangular, internally yellow perianth lobes, but differs by its urceolate perianth with an internally purplish red tube, and stamens inserted in the middle of the perianth tube, and mushroom-shaped pistil.
