Hansenia trifoliolata Q.P.Jiang & X.J.He (Apiaceae), is described as new from Shaanxi Province, northwest China. The mericarp features of H. trifoliolata resemble H. himalayensis and H. phaea and molecular phylogenetic analyses (combining ITS and plastid genomes data) suggest that H. trifoliolata is closely related to the group formed by H. oviformis and H. forbesii. The new species H. trifoliolata has unique 3-foliolate leaves and differ from other Hansenia species in its leaves, umbel numbers and size. A comprehensive description of H. trifoliolata is provided, including habitat environment and detailed morphological traits.
