摘　　要：在忍冬属Lonicera L.植物研究过程中,发现华东地区的倒卵叶忍冬L. hemsleyana (Kuntze) Rehder和《浙江植物志》记载的蕊被忍冬L. gynochlamydea Hemsl.,分别与华中地区的华西忍冬L. webbiana Wall. ex DC.和蕊被忍冬在枝、叶等营养体器官形态上高度相似,但双花的相邻2萼筒(连同子房)的融合程度相差甚远,且与地理分布相吻合。从植物地理学角度研究论证上述2组近缘类群系植物由西向东迁移过程中独立演化形成的2对地理替代种,并据此对其分类地位进行了修订:(1)将倒卵叶忍冬组合为华西忍冬的亚种,即:L. webbiana Wall. ex DC.subsp.hemsleyana(Kuntze)Z.H.Chen,G.Y.LietW.Y.Xie;(2)描述了蕊被忍冬一新亚种:大盘山忍冬L.gynochlamydea Hemsl. subsp. dapanshanensis Z. H. Chen, G. Y. Li et J. S. Wang。华西忍冬和倒卵叶忍冬、蕊被忍冬和大盘山忍冬,它们是亲缘关系密切的类群,是植物系统发育生物学研究的理想材料。It was found that Lonicera hemsleyana in East China and recorded specimen L. gynochlamydea in Zhejiang province were highly similar to L. webbiana and L. gynochlamydea in Central China in terms of vegetative organs, such as branches and leaves, but the extent of fusion of neighboring two calyx tubes(along with ovaries) of the paired flowers were very different, which was phytogeographically consistent with their geographical distributions. These two groups of taxa were two pairs of geographical substitutes, which forming through the migration from west to east. Their taxonomic was revised as follows: L. hemsleyana was actually a subspecies of L. webbiana, L. webbiana subsp. hemsleyana. A new subspecies of L. gynochlamydeawas described, L. gynochlamydea subsp. dapanshanensis.
