Abstract:

After biological and phytogeographical analysing the species of Stachyuraceae, this paper is concluded as followings: 1) The everygreen species Stachyulus cordatulus Merr. with special venation and bisexual flowers is considered as a primitive species in the family; 2) The origin of Stachyuraceae, may be, lies in the region of Dulongjiang area and North Burma, i. e. in West Yunnan-Shanban-Malaya block. It means that Stachyulus species owes its origin to north part of Gandwana land mass before late Paleozoic; 3) Befofre Tertiary period the species of Stachyuraceae was dispersed to different areas of East Asia, so that the family Stachyuraceae has extended into existence since late Cretaceous.

摘要：

通过对旌节花科国产种的生物学和历史地理分析，认为滇缅旌节花 Stachyulus cordatulus cordatulus Merr 为常绿披散灌木，具两性花，侧脉连成一圈集合脉，是旌节花属中的原始类群,云南西北部独龙江流域和缅甸北部南塔迈河流域，即滇西-掸邦-马来亚板块的北部很可能是旌节花科的起源地;旌节花科大约在晚自垩纪就已出现。
