    摘要:

    描述了产自广西木兰科一新种：靖西长喙木兰（Lirianthe jingxiensis Y.H.Tong&N.H.Xia）。本种形态上与绢毛木兰[L.albosericea（Chun&C.H.Tsoong） N.H.Xia&C.Y.Wu]接近，但区别在于该种植株较矮，幼枝、叶柄和幼叶被黄棕色绢毛，叶柄较宽，叶片较宽，倒卵形或倒卵状椭圆形，先端钝或短渐尖，花被片较大，心皮数目较多，被黄棕色绢毛。

    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.
