       Abstract: Paraboea nanxiensis Lei Cai & Gui L. Zhangꎬ a new species of Gesneriaceae from karst area around the
       Sino ̄Vietnamese borderꎬ is described here. The new species is morphologically similar to P. nutans D. Fang & D. H. Qin

       in the shape and indumentum characters of leaf bladeꎬ color of flowerꎬ length of the inflorescence and glabrous pistilꎬ
       but it can be easily distinguished by the shape of the corollaꎬ the color of flower interiorꎬ the shape and indumentum of
       calyx lobesꎬ and capsule morphology. The detailed descriptionsꎬ color photographsꎬ distribution and ecologyꎬ as well as
       its morphological relationship with similar species are also provided. In recent yearsꎬ many new taxa or newly record spe ̄
       cies have been found in limestone areas along the Sino Vietnam borderꎬ it is necessary to strengthen the investigation of
       plant diversity for better understanding the high biodiversity in this area.
