Parasenecio dissectus Y.S. Chen, sp. nova (Asteraceae) from Hubei province (China) is described and illustrated. It is similar to P. sinicus, but differs from it by its much larger leaves usually with more lobes, smaller capitula, five phyllaries and florets, longer florets, shorter achenes and white pappus. Parasenecio levingii (C.B. Clarke) Y.S. Chen, comb. nova is proposed based on Senecio levingii from west Himalayan region.
