Chamaesium jiulongense X. L. Guo & X. J. He, a new species of Apiaceae from Mt Haite in Jiulong County, Sichuan Province, China, is described. The new species differs from other Chamaesium species by its ultimate segments of the leaves which are 1–3‐lobed, rarely entire, with a narrow, minutely incised, pale brown margin, as well as by the presence of leaf‐like bracts, bracteoles longer than flowers, pubescent styles and oblong fruit with obsolete calyx. Morphological and micromorphological characters of the new species are provided and illustrated.
