摘要
整理研究了甘肃省所产六道木属植物，确认分布有ＡｂｅｌｉａｐａｒｖｉｆｏｌｉａＨｅｍ－ｓｌ．，Ａ．ｅｎｇｌｅｒｉａｎａ（Ｇｒａｅｂｎ．）Ｒｅｈｄ．，Ａ．ｄｉｅｌｓｉ（Ｇｒａｅｂｎ．）Ｒｅｈｄ．等３种，集中于甘肃东南部山地林区，采用形态地理学方法初步探讨了二花六道木亚组Ｓｕｂｓｅｃｔ．ＢｉｆｌｏｒａｅＲｅｈｄ种间关系及演化式样，认为聚伞花序的简化是这一种群组合主要的分化途径。
This paper has sorted out 3 species of Abelia R. Br. ( Capri-foliaceae ) in Gansu Province. These species include A. parvifolia Hemsl., A.engleriana (Graebn.) Rehd. , and A. dielsii (Graebn) Rehd.They are concentratively distributed in the mountain area in the Southeast of Gansu.Theinterspecies relationships and evolutionary pattern of the Subsect. Biflorae Rehd. were discussed morphogeologically. The simplization of cyme wasconsidered as the essential path of differentiation of species.
