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.
Desf 包括广泛分布于亚热带和热带地区的物种。然而，很少有研究关注 Desf 物种的微观解剖学特征，也没有对 Desf （L.）Hassk. 的特征进行鉴定。因此，在本文中，我们研究了来自广治省的 Desf 物种的根、茎和叶形态的分类学意义。我们的研究主要使用了光学显微镜。定性特征如茎四棱形，多毛；叶对生，卵形，边缘具锯齿；花萼钟形；花冠小，裂片相等，这些特征在研究物种的地上部分时被发现。我们还检查了表皮细胞形状、垂周壁、毛状体类型、气孔类型和草酸钙晶体类型等表皮解剖学特征。叶片和花序的长度和宽度、油滴、气孔和草酸钙晶体的大小等定量特征的测量提供了分类学意义。通过识别 Desf 物种的形态特征，我们旨在为该属的分类学研究做出贡献，并与其他分类群进行相对的形态和微观解剖学特征比较。
