Comparative anatomical studies of some Teucrium sect. Teucrium species: Teucrium alyssifolium Stapf, Teucrium brevifolium Schreb. and Teucrium pestalozzae Boiss. (Lamiaceae)
MetadataShow full item record
Teucrium alyssifolium Stapf (endemic), Teucrium pestalozzae Boiss. (endemic) and Teucrium brevifolium Schreb. are three closely related taxa in Teucrium sect. Teucrium. The obtained data from the anatomical studies revealed that these three taxa represent the general anatomical characteristics of the Lamiaceae family. Leaves, anatomical features such as thick cuticle, abundant trichomes, rich palisade parenchyma layer in the mesophyll provide evidence that these three species are xeromorphic structures. Leaf and stem anatomy showed that the taxa have generally similar anatomical features. However, cuticle layers, epidermis cells size, indumentum density, mesophyll types, palisade parenchyma occupied in the mesophyll, presence of spherocrystals in leaves and parenchyma, collenchyma and sclerenchyma layers in stems show differences amongst the taxa. Anatomical characters of leaf and stem of these taxa are examined for the first time in this study.
