摘要：花楸（Sorbus calcicola W.）B。Liao et W.本文描述了采自中国广西的狭分布新种Guo。与形态学上相近的种S. pallescens，S. cuspidata和S. thibetica也讨论了。利用nrITS基因沿着进行系统发育分析，结合叶背面无毛或脉腋被绒毛、侧脉5-6对、伞房花序3-7朵等形态特征，证实该种为一个独立的新种。
Abstract.Sorbus calcicola W. B. Liao et W. Guo, a new narrow-range species from Guangxi Province in China, is described and illustrated here. Its relationships with morphologically close species S. pallescens, S. cuspidata and S. thibetica are also discussed. Phylogenetic analyses with nrITS gene along with a number of morphological features including leaves abaxially glabrous or tomentose in vein axils, lateral veins 5–6 pairs and corymbs inflorescence with only 3–7 flowers confirmed that it is a distinct new species.
