摘　　要：对中国产榆科８属、２６种植物的果实和种子形态进行了研究，包括果核表面的电镜扫描。编制了种子、果实分属检索表，简要记载了榆科８属果核表面电镜扫描特征。以果实、种子形态特征为主，参阅花粉和种子油脂肪酸资料及腊叶标本，进行了３６个性状的聚类分析。参阅其他有关文献，支持把刺榆属Ｈｅｍｉｐｔｅｌｅａ及榉属Ｚｅｌｋｏｖａ划归榆亚科Ｕｌｍｏｉｄｅａｅ，把朴亚科由榆科中独立成朴科Ｃｅｌｔｉｄａｃｅａｅ的意见。The morphology study of fruits and seeds of 26 species,8 genera of Ulmaceae in China including fruit core surface scanning by using electron microscope,making index table for classification of these genera and describing the characteristics of the fruit core surface of the 8genus under scanning electron microscope .Based on the morphologic characteristics of fruits and seeds with referring to data of pollen and fatty acid in seed oil, and the plant specimens,the cluster analysis of 36 characters was carried out.According to the researches and related references,authors agreed with and supported the idea that the genera Hemiptelea and Zelkova should be reclassified into subfamily Ulmoideae, and the subfamily of Celtidoildeae should be separated from family Ulmaceae as an independent family Celtidaceae.
