摘    要:本文所谓狭义的忍冬科,包含4族、12属即忍冬族(忍冬属、鬼吹箫属),北极花族(毛核属,糯米条属、六道木属、北极花属、双盾木属、猬实属、七子花属),锦带花族(德维花属、锦带花属)和莛子?族(莛子?属)。基于它们的分布、化石资料和以木本为主的特性,忍冬科可认为是一个古老的科,可能起源于晚白垩纪或早第三纪。又基于以下事实:在东亚糯米条属、莛子?属和锦带花属中,可见到一系列的系统发育列;东亚特有的七子花属,是联系忍冬族和北极花族的一个中间纽带;东亚不但有较高比例的古特有属,还有一些新特有属;由此,我们认为东亚是该科的多样化中心。在化石和细胞学资料不充分的情况下,我们仅根据三个主要特征,如属的系统位置是否孤立,与近缘属的分布区是否间断及属内的分化类型的多寡和种间的区别是否明显,试图将6个东亚特有属归为三类:七子花属、双盾木属和猬实属作为古特有属,锦带花属作为活化了的古特有属,六道木属和鬼吹箫属作为新特有属。

关 键 词:忍冬科  植物地理  东亚植物区系

Abstract:; The Caprifoliaceae s. str. as here defined consists of 4 tribes and 12 genera; Caprifolieae (Lonicera, Leycesteria ) , Linnaeeae (Symphoricarpos, Abelia, Zabelia, Lin-naea, Dipelta, Kolkwitzia, Heptacodium ) , Diervilleae (Diervilla, Weigela ) , Triosteae (Triosteum). Based on chorology, fossil records and dominant woody habit, the family may be considered as a fairly old one and probably originated in the Late Cretaceous or the Early Tertiary. In the light of facts, such as a number of phylogenetic series of Abelia, Triosteum and Weigela occurring in east Asia, Heptacodium, endemic to East Asia, as a link between the tribe Caprif olieae and the tribe Linnaeeae, and existence in East Asia of a high percentage of both palaeoendemic genera and some neoendemics, East Asia seems to be the center of diversity of the family. Six Eastern Asiatic endemic genera might be grouped under three categories, Heptacodium, Dipelta and Kolkwitzia as palaeoendemics, Weigela as active epibiotics, and Zabelia and Leycesteria as neoendemics. The above inferences are made only on the basis of three main attributes, systematic position of genera isolated or not, their geographical distribution continuous or discontinuous with the closest relatives and the degree of diversification of forms or distinction between species within a genus, without consideration of insufficient fossil records and cytological data.
Keywords:Caprifoliaceae  Phytogeography  Eastern Asiatic flora
