Teucrium sect. Chamaedrys

The reticulate-alveaolate surface ornamentation was discovered. The taxa of this section do not have eglandular trichomes on the nutlets. The leaves of the studied species in this section are characterized by the homogeneity of the trichome types. All leaves have B and G type hairs. In addition, A 2 type glandular hairs have observed on the leaves of T. chamaedrys Linnaeus (1753: 565) subsp. chamaedrys and T. leucophyllum Montb. & Aucher ex Bentham (1836: 55) ( Figs. 1 , 2 , 4 , 5 and Table 2).
