| 摘 要： | 通过对重寄生属植物及其寄主的地理分布状况的讨论,对重寄生属植物可能的起源时间、地点与迁 移进行了分析。重寄生属植物主要寄生在桑寄生科(Loranthaceae)植物上,重寄生属植物的分布区与其寄主 的基本一致,均主要分布在东南亚和中国南部的热带与亚热带地区;重寄生属植物可能起源于第三纪之前某 一时期的华南热带地区,随后向周边地区扩散。在第三纪,重寄生属植物的祖先偶然寄生在桑寄生科某些寄 生植物祖先上,经过几千万年的协同进化,形成了今天比较稳定的寄生与寄主关系。

| Abstract: | Based on the geographical distribution of the species of Phacellaria and their host plants in the world,the possible time,site and migration of origin of Phacellaria were speculated. The host plants of Phacellaria mainly belong to Loranthaceae. Plants of Phacellaria and their hosts were mainly distributed in tropical and subtropical area. Plants of Phacellaria maybe originated in tropical area in the south of China before Tertiary. Their ancestors were parasitic on ancestors of some plants of Loranthaceae by chance during Tertiary. It took them millions of years to form a sturdy relationship between parasites and hosts. |
