| 摘要: |
| 基于近年来的研究成果,对五味子科的分类地位和系统关系、五味子属和南五味子属之间的关系及其分类系统等问题进行了讨论。五味子科和八角科不仅亲缘关系较近,而且是现存被子植物中最早分化出来的类群,把它们同置于八角目是合理的。五味子科的两个属——五味子属和南五味子属,可能源于同一祖先并沿两条不同演化路线平行演化。目前,关于南五味子属的分类系统的意见比较一致,但对五味子属分类系统的分歧却很大 |

| Abstract: |
| Based on the references concerned to Schisandraceae,several taxonomical problems,such as systematical position of Schisandraceae,relationship between Schisandra and Kadsura,and their system were discussed. The results showed that Schisandraceae and Illiciaceae not only closely correlated systematically,but also be one of the earliest differentiated taxa in the extant angiosperm,it was reasonable to place the tow families in Illiciales. Schisandra and Kadsura,the two genus of Schisandraceae,maybe originated from common ancestor,and evolved parallelly in different ways. Compared to the genus Kadsura,of which the system has come to an agreement,it shows a great difference in system of Schisandra taxonomically. |
