The results of the study of morphological and biochemical attributes of Spiraea betulifolia and S. beauverdianа and their eco-geographical variability were given. Taxa diagnostic features were identified: the characteristics and degree of pedicle and leaflet pubescence, leaflet rostrum position, the composition of phenolic compounds. On this basis, the independence of these two species was proposed.
