Abstract: | Ferula paeoniifolia X. G. Ma & C. Y. Liao sp. nov., from Sichuan Province, Southwest China, is described and illustrated. The new species is most similar to F. kingdon‐wardii Wolff in morphology, but differs significantly in its ternate‐2‐pinnate compound leaves with much broader leaflets. The key morphological characteristics and nuclear ribosomal internal transcribed spacer (ITS) region were also compared between F. paeoniifolia and its relatives. |
