| 摘 要： | 利用光镜，扫描电镜对狗娃花属（Heteropappus)7种植物的花粉形态和结构进行了观察研究。发现该属植物花粉粒为近球形或长球形，3孔沟，具刺状纹饰，种间花粉差异主要表现在大小，形状和外壁纹饰细微变化等方面，该属花粉与紫菀属（Aster)和乳菀属（Ca-latella)的相似。表明它们有密切的亲缘关系。 |

| Abstract: | This study presents a detailed survey and discussion on the pollen morphology and structure of seven species of Heteropappus with light microscope (LM) and scanning electron microscope(SEM). Measurements of the polar axis and equitorial diameter, exine thickness, spine length, and spine number at each lobe are made. The principal differences in pollen among various species are in size, shape and subtle variations of the surface ornamentation. The pollen grains of Heteropappus are similar to those of Galatella, suggesting a close relationship between these two genera. These two genera can be viewed as the satellite genera of Aster. |
