The purpose of this paper is to highlight the morphological peculiarities of glandular and non-glandular trichomes from leaves of subsp. using light, confocal, and scanning electron microscopy. Histochemistry techniques were used to analyze the localization of different chemical compounds in secretory trichomes. Two types of non-glandular trichomes were identified: unicellular and branched. They were found more frequently on the lower epidermis of leaves in different stages of ontogenetic development. Glandular trichomes were categorized as capitate (C1 and C2) with different stalk lengths and one-four secretory cells and dendroids (D) with one-four secretory cells. The histochemical analyses revealed distinct secretory products in terms of composition and distribution among the three types of glandular trichomes. The dendroid category of glandular trichomes is rarely found in plants and is not characteristic of the Lamiaceae species. They were described and characterized from a micromorphological and histochemical point of view for the first time in .
本文的目的是利用光学显微镜、共聚焦显微镜和扫描电子显微镜，突出亚种叶片腺毛和非腺毛的形态学特征。采用组织化学技术分析分泌毛中不同化合物的定位。鉴定出两种类型的非腺毛：单细胞毛和分枝毛。它们在个体发育不同阶段的叶片下表皮更为常见。腺毛分为头状（C1和C2），具有不同的柄长和1 - 4个分泌细胞，以及树状（D），具有1 - 4个分泌细胞。组织化学分析揭示了三种类型腺毛在组成和分布方面不同的分泌产物。腺毛的树状类型在植物中很少见，不是唇形科物种的特征。首次从微观形态学和组织化学角度对它们进行了描述和特征分析。
