| 摘 要： | 本文首次用扫描电镜观察小花脓疮草的花粉形态。该种花粉粒赤道面观为近长球形；极面观为近圆形或三裂圆形。大小为（２０．８３～３０．７５μｍ ）２４．３７μｍ ×１９．７７μｍ （１６．７５ ～２３．３２ μｍ ），极轴／赤道轴为１．２３，具三沟，沟几乎长达两极，沟膜上具颗粒。花粉外壁纹饰为穿孔—网状。从花粉形态上看，该种与脓疮草属其他种（即脓疮草Ｐａｎｚｅｒｉｎａ ｌａｎａｔａ）的花粉特征相差不大，在大小、萌发孔以及纹饰上区别不明显

| Abstract: | The pollen morphology of Panzerina parviflora has been observed by scanning electron microscope for the first time . Pollen grains are subprolate , 24.37 μm×19.77μm averagely ,pole axis/equator axis is 1.23,tricolpate with the granulation on colpate-membrane.The ornamentation of exine is perforate -reticulate. From the above study , It is indicated finally that The pollen morphology between Panzerina parviflora and the others in Panzerina is relatively similar ,and there is a little difference in the size ,aperture and ornamentation of the pollen. |
