摘要
本文用谱系分支法分析睡莲科的属间关系。３５个衍征中，分析了３１个特征的进化趋势。根据分析将睡莲科提升为睡莲目，分为３个科：莲科、水盾草科、睡莲科。
In this paper,a cladistic analysis was applied to reveal the phylogenetic relationships among the Nymphaeaceae.Thirty one out of thirty five characters in gross morphology,anatomy and palynology were analyzed for their evolutionary polarities.A conclussion obtained from the present analysis was that following three families should be recognized in the Nymphaeales(Nelumbonaceae,Cabombaceae and Nymphaeaceae).
