“… 2 , 38 P. auricularius possessed morphological traits were featured as opposite leaves with blade ovate-oblong and having pilose on both sides; flowers are nearly subsessile (calyx campanulate is 1 mm long, corolla white or purplish, approximately 3 mm long). 13 , 39 It had stamens four that was approximately 3 mm long and lower pilose. According to the infrageneric taxonomy, P. auricularius appeared to belong to the subgenus.…”

“…The sections were observed using light microscopy to photograph, and the micro-morphology characteristics were recorded. 13,[29][30][31] Botanical characteristics of samples were described and compared to plant taxonomic documents and stored templates at the Institute of Ecology and Biological Resources, VAST, with the assistance of scientific botany specialists. Cutting, bleaching, and double staining methods were used in conjunction with the electron microscope and digital microscope to observe, photograph, and study the microscopic characteristics of P. auricularius.…”

Pogostemon Desf . includes a wide range of taxa found in subtropical and tropical areas. Few works, however, have studied microanatomical characteristics of Pogostemon species and as yet identified features of Pogostemon auricularius (L.) Hassk. Thus, in this paper, we examined the taxonomic implications of root, stem and leaf morphology for species P. auricularius 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 P. auricularius. 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 P. auricularius, we aimed to contribute to the taxonomic investigation into the genus Pogostemon and give relative morphological and microanatomical features compared with other taxa.
