Abstract:A new species of Lirianthe (Magnoliaceae) from Guangxi, China, L. jingxiensis Y. H. Tong & N. H. Xia, is described and illustrated here. This species is morphologically most similar to L. albosericea (Chun & C. H. Tsoong) N. H. Xia & C. Y. Wu, but differs in having a much shorter height, young branches, petioles and leaf blades with yellowish-brown sericeous trichomes, wider petiole, wider leaf blades with an obovate or obovate-elliptic shape and an obtuse or shortly acuminate apex, larger tepals and more carpels covered with yellowish-brown sericeous trichomes.
