● One species: China.

This genus is not only in aspect but also in the head arrangement closely related to Ligularia; however, it differs by its petioles winged, expanded and subamplexicaul, but not vaginate at base; capitula discoid, in terminal racemes; and florets 4, all tubular. The genus is also related to Parasenecio but differs by its anthers obtuse, not caudate at base; stem leaf base with relict petioles; and basal leaves persistent by anthesis.
