Taxonomical and Phytochemical Characterisation of 10 Stachys Taxa Recorded in the Balkan Peninsula Flora: A Review

The genus Stachys is one of the largest genera of the Lamiaceae, and it comprises about 300 species. Some species are highly polymorphic, with a number of infraspecific taxa. The aim of the present review is to summarise the available knowledge on 10 taxa belonging to the Balkan Peninsula flora (S. alpina L., S. germanica L., S. menthifolia Vis., S. obliqua Waldst. Et Kit., S. officinalis (L.) Trevis., S. palustris L., S. recta L. subsp. recta, S. recta L. subsp. subcrenata (Vis.) Briq., S. salviifolia Ten., and S. sylvatica L.) in order to enable insight into the identified biologically active substances and their possible application in intrageneric differentiation
