A study on the types and distribution of trichomes, pollen morphology, chemical composition of essential oil (analyzed by GC-FID and GC/MS), and the content of macroelements (Na, K, Ca, and Mg) and trace elements (B, Fe, Cu, Mn, Zn, Al, Pb, Cr, Cd, Ni, Hg, and As) analyzed by ICP-AES (=inductively coupled plasma atomic emission spectroscopy) was conducted on Micromeria croatica (Pers.) Schott. Non-glandular trichomes, peltate trichomes (typical hairs of Lamiaceae), small capitate trichomes (composed of one basal epidermal cell and one head cell), and larger capitate trichomes (composed of one basal epidermal cell, two to three stalk cells, and one head cell with subcuticular space) were observed on leaves, stems, the calyx, and corolla. Pollen of M. croatica had six apertures (hexacolpate) which were set in the equatorial pollen belt (zonocolpate) and showed medium reticulate ornamentation (hetrobrochate type). The essential oil contained from 27 to 39 constituents, the most representative of which were caryophyllene oxide and E-caryophyllene. Among the investigated macroelements, the content of K was highest (8730-10080 mg/kg). The content of trace elements ranged from 0.12 mg/kg (Cr) to 78.00 mg/kg (Fe), while the content of Cd, Ni, Hg, and As were lower than the limit of quantification.
对克罗地亚小米草（Micromeria croatica (Pers.) Schott）进行了毛状体类型和分布、花粉形态、精油化学成分（GC-FID 和 GC/MS 分析）以及宏量元素（Na、K、Ca 和 Mg）和微量元素（B、Fe、Cu、Mn、Zn、Al、Pb、Cr、Cd、Ni、Hg 和 As）含量（ICP-AES 分析）的研究。在叶片、茎、花萼和花冠上观察到非腺毛状体、盘状毛状体（唇形科的典型毛状体）、小头状毛状体（由一个基表皮细胞和一个头细胞组成）和较大的头状毛状体（由一个基表皮细胞、两个到三个柄细胞和一个带有下皮空间的头细胞组成）。M. croatica 的花粉有六个孔（六孔），分布在赤道花粉带（ zonocolpate ），具有中等网状纹饰（ hetrobrochate 型）。精油含有 27 到 39 种成分，其中最具代表性的是石竹烯氧化物和 E-石竹烯。在所研究的宏量元素中，K 的含量最高（8730-10080mg/kg）。微量元素的含量范围从 0.12mg/kg（Cr）到 78.00mg/kg（Fe），而 Cd、Ni、Hg 和 As 的含量低于定量限。
