Taxonomic Studies on the Genus Delphinium (Ranunculaceae) from China (V): Two New Synonyms of D. autumnale

Abstract:

Delphinium liangshanense W. T. Wang and D. leiostachyum W. T. Wang (Ranunculaceae) were described respectively from Yuexi and Muli in southwestern Sichuan, China. Both herbarium and field observations have shown that they represent no more than a taller form of D. autumnale Hand.-Mazz., a species previously recorded to occur in southwestern Sichuan (Muli, Yanyuan) and northwestern Yunnan (Ninglang). We therefore reduce them to the synonymy of D. autumnale.
