本文採集31種，分屬於16科之蜜源植物之花粉，先以濃硫酸及無水醋酸處理，再經固定、脫水 、臨界點乾燥及金屬離子覆膜後，以掃描式電子顯微鏡觀察其表面之微細描造。本文對蜂蜜花粉形態提供更詳細的描述，並對蜂蜜種類之鑑定提供更精確之資料。

The morphology of pollen from those plants contributing as nectar sources were observed with scanning electron microscopy (SEM). The pollen samples were subjected to acetolysis, fixation, dehydration, critical point drying and subsequently coating with gold. The ultrastructure of pollen of thirty-one species belonging to sixteen families were described. The results can provide with more information about the honey pollen and criteria for identification of honey species precisely.
