摘 要 ：对旌节花科及其相关类群五桠果科、猕猴桃科、水东哥科、金莲木科、省沽油科和山茶科等7科19属37种花粉进行了光镜(LM)和扫描电镜(SEM)的观察和比较。其中有些种类是第一次观察和报道。研究表明，上述各科花粉多为近球形至球形少数近扁球形或近长球形。极面观三裂圆形或近三裂圆形。直径20-30(-35)μm,但厚皮香亚科和省沽油科银鹊树属Tapiscia的花粉特别小，仅12.5-20μm。3孔沟罕有3沟或4孔沟。外萌发孔(沟)相对地较长而宽，内孔多娄较发达花粉外壁纹饰变化大从模糊而粗糙的细突韦到皱波状纹饰，细孔状纹饰蜂巢状-穴状纹饰穴-网状纹饰网状纹饰和颗粒状纹饰等。

Abstract:The pollen grains of 37 species belonging to 16 genera of 7 families, i.e.,Stachyuraceae,Dilleniaceae,Actinidiaceae,Saurauiaceae,Ochnaceae,Staphyleaceae and Theaceae were examined by light and scanning eectron microscopes,Sone species were examined by scanning electron microscope or reported for the first time.The result showed that most pollen grains are 3-lobed circular or sub-3-lobed circular in outline in polar view,the shape varies from suboblate to subprolate but most are subspheroidal to spheroidal.
