The study was conducted to highlight a detailed account of morphology of pollen chosen species of Lamiaceae through scanning electron microscopy, and the anatomical characteristics of leaf epidermis of seven species using simple light microscopy. In results, Anisomeles indica and Otostegia aucheri belong to subfamily Lamioideae because it has tricolpate pollen while the rest eight species belong to subfamily Nepetoideae (hexacolpate pollen). The exine sculpturing of pollen of studied species was found to be reticulate. In the family Lamiaceae, four kinds of stomata were found anomocytic, anisocytic, diacytic, and actinocytic, respectively. The cell wall patterns of epidermal cells were irregular or polygonal with straight or undulate walls. It was noted that the variety of the epidermal trichomes seems of taxonomically important for the identification of species of Lamiaceae. Both nonglandular and glandular trichomes were analyzed. The nonglandular trichomes were characterized with long, thin, and pointed apical unicellular cells. The nonglandular trichomes were A‐shaped in Thymus linearis. In Perovskia abrotanoides, stellate glandular trichomes were observed whereas in A. indica and Mentha royleana both glandular and nonglandular trichomes were found. In A. indica, the nonglandular trichomes were sessile and peltate in M. royleana. For the first time in this study, pollen and foliar micromorphological features of selected species of this area are carried out. These taxonomic characters were found to be important in discrimination of species from each other. In future, the detailed study with comprehensive morphology coupled with other important characters is required for delimitation of taxa at various levels.

使用光学显微镜和扫描电子显微镜对喜马拉雅西部德奥西高原高寒地区某些选定的菊科物种进行的花粉和叶微形态学比较研究。

进行这项研究的目的是通过扫描电子显微镜来突出详细说明唇形科花粉选择物种的形态,并使用简单的光学显微镜对七种植物的叶表皮的解剖特征进行详细描述。结果,印度无茴香耳骨耳麦属于Lamioideae亚科,因为它具有三col科花粉,其余八种属于Nepetoideae(六col科花粉)亚科。发现被研究物种的花粉的外壁雕刻是网状的。在唇形科中,分别发现了四种气孔,分别是单核的,异种的,双酰基的和放线的。表皮细胞的细胞壁模式是不规则的或多边形的,具有直的或起伏的壁。注意到表皮毛状体的变化对于识别唇形科的种类在分类学上似乎很重要。分析了非腺毛和腺毛。非腺毛状体的特征是长,细,尖的单细胞。线状胸腺中的非腺毛状体为A形。在观察到Perovskia abrotanoides,星状腺毛状体,而在印度A草薄荷叶中发现了腺毛和非腺状毛状体。在印度A(A. indica)中,蔷薇(M. royleana)的非腺毛状体是无柄的和球形的。在这项研究中的第一次,该地区的选定物种的花粉和叶微形态特征进行了。发现这些分类学特征在区分物种之间很重要。将来,需要对形态学进行综合研究并结合其他重要特征,以便在各个层次上对分类单元进行划界。
