This paper presents the results of studies of exocrine secretory tissues in two representatives of the Lamiaceae family, Stachys sylvatica and Clinopodium vulgare, which are promising for use in traditional medicine. Using light and fluorescence microscopy, data were obtained the morphology, size, and density of glandular trichomes of the leaves, stems, and sepals. It was established that, on the epidermis of the studied species, there are five types of exocrine structures, which differ in the number of stalk and head cells. It was revealed that each plant species has its own set of excretory formations; so, short capitate trichomes with a four-celled head are found only in Stachys sylvatica, peltate trichomes and short trichomes with a single-celled head are found only in Clinopodium vulgare, and long glandular trichomes with six-celled heads are found in the epidermis of the sepals in both species. For the first time, data were obtained on the diversity of glandular trichomes in the epidermis of the stem of Stachys sylvatica and morphological types of the glandular structures in the epidermis of various organs of Clinopodium vulgare were described. Information is given on the morphometric differences between different types of capitate trichomes. The density of the capitate trichomes is higher than that of the peltate trichomes and varies depending on the organ on which they develop. It was found that small capitate trichomes in the epidermis of the Stachys sylvatica sepals, as well as in the epidermis of a stem and abaxial side of the leaves in Clinopodium vulgare, have had a higher density than do other types of the glandular structures.
