Morpho-Anatomical Study And Botanical Identification of (L.) Hassk. (Lamiaceae).

Desf includes a wide range of taxa found in subtropical and tropical areas. Few works, however, have studied microanatomical characteristics of species and as yet identified features of (L.) Hassk. Thus, in this paper, we examined the taxonomic implications of root, stem and leaf morphology for species collected from Quang Tri Province. Light microscopy was mainly used in our study. Qualitative characters like stem quadrangular, hirsute; leaves opposite, ovate, margin serrulate; calyx campanulate; corolla small with separate equal lobes have been found in Epidermal anatomy on the aerial parts of the species like epidermal cell shape, anticlinal walls, trichomes types, stomata types and calcium oxalate crystals types were examined as well. Quantitative characters like the length and width of leaf blade and inflorescence; the size of oil droplet, stomata and calcium oxalate crystals measured provided taxonomic significance. Based on identifying morphological characteristics of , we aimed to contribute to the taxonomic investigation into the genus and give relative morphological and microanatomical features compared with other taxa.
