The results show that the first stem is Aconitum carmichaelii, the herbaceous is erect. Cone root roots, with tubers and tubers. The seedling leaves are heart-shaped, almost round, like mugwort. The leaves are divided into 3 irregular lobes, the edges of the lobes are serrated. The primary shell has a large number of cork-like capi, consisting of 2-3 rows of cells close to the inner shell, wood and bile diverging radially and there are 3 different types of bundles, intestinal soft tissue. The gas layer concentrates heavily on the underside of leaves, petioles have a straight epidermis, thin walls. Thick tissue grows concentrated in the corner. Soft tissue growth contains chloroplasts. Conductive bundles, interspersed and hard surrounding tissue. The rpoC1 gene isolated from the first cell has a size of 543 nucleotides, the rpoB2 gene has a size of 471 nucleotides.
