Taxonomic Studies on the Genus Delphinium (Ranunculaceae) from China (IV): The Identity of D. quinqueflorum

Abstract:

Both herbarium and field observations have shown that Delphinium quinqueflorum W. T. wang (Ranunculaceae) described from Zhongdian, Yunnan, China, is no more than a smaller form of D. thibeticum Finet & Gagnep., a species very common in that area. We therefore reduce D. quinqueflorum to the synonymy of D. thibeticum.
