Abstract: One species and one variety of Aconitum and Delphinium each, one species of Thalictrum, one subspecies of Adonis, and five species of Ranunculus are described as new. The new finding of Thalictrum rotundifolium from southern Xizang is reported, and after analysing the morphological characters of leaves, stamens, and carpels, this species is con-sidered to be more or less related to T. scabrifolium, a species endemic to Yunnan.
