摘要
讨论了睡莲目的地理分布，将现存睡莲目（３科９属）分布区归纳为以下分布类型：（一）热带分布类型（１）热带亚洲分布：Ｂａｒｃｌａｙａ，（２）热带美洲分布：Ｖｉｃｔｏｒｉａ，（３）热带澳洲分布：Ｏｎｄｉｎｅａ；（二）温带分布类型（４）温带亚洲分布：Ｅｕｒｙａｌｅ，（５）欧亚—北美连续分布：Ｎｕｐｈａｒ，（６）亚洲—澳洲—美洲—非洲间断分布：Ｂｒａｓｅｎｉａ；（三）热带、温带分布类型（７）亚澳—北美间断分布：Ｎｅｌｕｍｂｏ，（８）世界性分布：Ｎｙｍｐｈａｅａ，（９）美洲分布Ｃａｂｏｍｂａ。进一步论述种和特有种的分布，并对睡莲目的分布区中心、起源时间、散布途径和现存分布式样形成的原因进行了初步讨论。
This paper aims to discuss the geographical distribution of the Nymphaeales.It is divided into the following three parts:1.The distribution patterns of nine living genera(three families)in the Nymphaeales.The fossil distribution and the geological date of the geographical distribution of the Nymphaeales genera,the distribution patterns may be divided as follows:A.The tropical distribution pattern a.The genus of tropical Asia destribution: Barclaya b.The genus of tropical America distribution :Victoria c.The genus of tropical Australia distribution :Ondinea B.The temperate distribution pattern d.The genus of temperate Asia distribution: Euryale e.The genus of distribution from Eurasia to north America: Nuphar f.The genus of disjunct distribution between Asia, Australia,America and Africa:Brasenia C. The tropical and temperate distribution pattern g. The genus of disjunct distribution between Asia-Australia and America:Nelumbo h.The Cosmopolitan distribution :Nymphaea i.The genus whose distribution is confined to America:Cabomba 2. The distribution of species According to Takhtajan’s view point of phytochoria the numbers of species and endemic species in every region are counted 3. Discussions of the distribution patterns of Nymphaeales There are following problemes:A.The centre of floristic region B. The time of the origin C.The routes of dispersal D.The formation of the modern distribution pattern and reasons for this formation.
