● Woods. S Hunan (Jianghua).

Sinosenecio qii is imperfectly known. It was described from a single locality in S Hunan. The type material includes only one fruiting plant without any florets. The species may be somewhat related to S. globiger, but it differs by the absence of stem leaves. More material is needed to confirm this character and to increase the list of differences between the species and its putative relatives.
