Paraboea nanxiensis (Gesneriaceae), a new species from southeastern Yunnan Province, China

摘要: Paraboea nanxiensis Lei Cai & Gui L. Zhang, a new species of Gesneriaceae from karst area around the Sino-Vietnamese border, is described here. The new species is morphologi-cally similar to P. nutans D. Fang & D. H. Qin in the shape and indumentum characters of leaf blade, color of flower, length of the inflorescence and glabrous pistil, but it can be easily distin-guished by the shape of the corolla, the color of flower interior, the shape and indumentum of ca-lyx lobes, and capsule morphology. The detailed descriptions, color photographs, distribution and ecology, as well as its morphological relationship with similar species are also provided. In recent years, many new taxa or new record species have been found in limestone areas along the Sino Vietnam border, it is necessary to strengthen the investigation of plant diversity for better under-standing the high biodiversity in this area.
