The description of the ontogenesis of type A millefolium is based on the forms of the ontogenetic condition. The plant was registered in immature (im), virgin (v), young generative (g1), middle age (g2), old generative (g3), subsenil (ss) and senil (s) periods. The obtained results were analyzed by comparison criterion c2. According to the results of the calculations show that the highest rate of A. millefolium is in the generative stages of development (225-243 pieces).
