| 摘要: |
| 采用光学显微镜和扫描电镜相结合，对山东丹参、丹参、南丹参发育良好成熟的花粉粒进行比较观察。结果表明：花粉粒形态、大小和外壁网状雕纹特征均具有较显著区别，首次为山东丹参新种积累孢粉学资料、确立其在植物分类学上的地位以及研究其种质，提供花粉形态的重要依据；丹参和南丹参花粉粒形态特征及外壁网状雕纹与前人报道相一致，为揭示山东丹参与丹参、南丹参之间的亲缘关系及种间分类鉴定提供了孢粉学依据；也为山东丹参药用植物新资源的开发提供科学依据。 |

| Abstract: |
| Well developed mature pollen grains of Salvia shandongensis，S.miltiorrhiza and S.bowleyana are examined by using light microscope and scanning electron microscope. The results indicated that there were clear distinctions among the shape，size and exine sculpture of S.miltiorrhiza plants’ pollen. This study not only first provided the important pollen morphological basis for accumulating the palynology information for S.shandongensis new species，establishing its position in plant taxonomy and researching its species quality； pollen grains morphological features and exine sculpture of S.miltiorrhiza and S.bowleyana were consistent with previous reports and provided the palynology information for revealing their genetic relationships of S.shandongensis，S.miltiorrhiza and S. bowleyana and distinguishing their species taxonomy，but also provided scientific basis for the development of new medicinal plant resources of S.shandongensis. |
