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。
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.
