Abstract:A new species of the genus Pleioblastus guilongshanensis M. M. Lin, from Fujian province, China, is described. The new species is related to P. yixingensis S.L.Chen & S.Y.Chen. However, it is distinguished by its longer internode (15~30 cm), young guilongshanensis covered with soft pubescences, the section with white powder under it; the upper pole-sheath without burnt margin; the sheath with spreading bristle.
