Two wild populations of (Mill.) located at Elba Island (Tuscan Archipelago, Central Italy) were morphologically and phytochemically analyzed to taxonomically identify (population A) and subsp. (population B). Micromorphological and histochemical analyses were performed on the using Scanning Electron Microscope (SEM) and Light Microscope (LM). Morphometric analyses on vegetative and reproductive traits were also conducted. Finally, a chemotaxonomic analysis was carried out on the terpene profile of flowers, leaves and bark tissues using gas chromatography (GC-MS). Results suggested that morphological discriminant traits were mainly in leaves and cypselae glandular tissues. Phytochemical analysis indicated that a high relative content of α-pinene and β-caryophyllene were the main markers for population A, while a high relative content of neryl-acetate, α-curcumene, isoitalicene and italicene, especially in the terpene profile of bark tissue, were the main compounds for discriminating population B. The analysis suggested that the wild population A could be mainly ascribed to , whilst population B is defined by .
对位于厄尔巴岛（意大利中部托斯卡纳群岛）的两种野生（Mill.）种群进行了形态学和植物化学分析，以从分类学上鉴定（种群A）和亚种（种群B）。使用扫描电子显微镜（SEM）和光学显微镜（LM）对进行了微观形态学和组织化学分析。还对营养和生殖性状进行了形态计量分析。最后，使用气相色谱法（GC-MS）对花、叶和树皮组织的萜类成分进行了化学分类分析。结果表明，形态判别特征主要存在于叶片和瘦果腺组织中。植物化学分析表明，α-蒎烯和β-石竹烯的高相对含量是种群A的主要标志物，而乙酸橙花酯、α-姜黄烯、异意大利烯和意大利烯的高相对含量，尤其是在树皮组织的萜类成分中，是区分种群B的主要化合物。分析表明，野生种群A主要可归为，而种群B则由定义。
