Research Abstract

Many Ligularia species in the Hengduan Mountains were found to harbor intra-specific diversity. Some morphologically similar Ligularia species were indistinguishable with respect to the chemical composition and the ITS sequences. The chemical compositions of Cremanthodium and Parasenecio were found to be similar to those in Ligularia. Hybridization was inferred to be an important factor in the evolution of Ligularia. Iris delavayi was found to harbor intra-specific chemical diversity, while Eupatorium heterophyllum was not.
