Cladistic relationship of the true fruit trees(Citreae, Rutaceae) is studied by character compatibility analysis. The cladogram based on primary clique of 7 morphological characters is presented. According to the cladogram, Citrus L. and Clymenia Swingl.

• 本文用相容性分析方法(Compatability snalysis)分析了真正柑桔果树群(芸香科Rutaceae-柑桔亚科Aurantioideae-柑桔族(Citreae)-柑桔亚族(Citrinae)植物内各属间的分支学关系。给出了建立在7个相容性性状组成的最大族所决定的分支图。性状极性的确定使用了外群法。结果表明；柑桔属(Citrus L.；)
