    Abstract

    During field work, a population of Chimonobambusa from limestone areas of southwest Guizhou, was discovered, appearing to be distinct from our previously identified collection. Based on morphological data, the new species is similar to C. szechuanensis (Rendle) Keng f. and C. convoluta Q. H. Dai & X. L. Tao, but differs by having a thinner culm with only 0.7–0.9 cm in diameter, shorter culm leaf blade, glabrous culm leaf and foliage leaf sheaths, absent culm leaf oral setae, wider leaf blade and more secondary veins. Thus, the new species, formally named as Chimonobambusa basisolida C.Y. Deng, Y.Y. Zhang & N.H. Xia, is described and illustrated herein. Based on its morphological characteristics, this new species is assigned to C. sect. Oreocalamus.
