The flowering plant family Sabiaceae comprises three genera and about 150 species of trees and shrubs that are distributed throughout the Neotropics and Southeast Asia. This group has not been subject to modern evolutionary research, and thus questions remain about the relationships among its members, as well as about the placement of the family among flowering plants. The main goal of this study is to generate a phylogenetic framework across taxonomic levels that will answer these questions and also allow the study of other aspects of the biology of the group, such as biogeography and the evolution of reproductive characters. To achieve this, modern methods, such as the comparison of gene sequences and phylogenetic dating using fossil information, will be used.This study will generate data that will improve our understanding of a recalcitrant part of the angiosperm tree of life. Furthermore, this study will test biogeographic hypotheses that have been proposed for other groups of plants with similar disjunct distributions, and fossil-based dating will provide geological timeframes in which the divergence and evolution of the family took place.

开花植物清风藤科包括三个属和约150种树木和灌木，分布在整个新热带地区和东南亚。这一组没有受到现代进化研究的影响，因此关于其成员之间的关系以及该家族在开花植物中的位置仍然存在问题。本研究的主要目标是产生一个系统发育框架，跨越分类学水平，将回答这些问题，也允许研究的其他方面的生物学的组，如植物地理学和生殖特征的进化。为了实现这一目标，将使用现代方法，如基因序列的比较和利用化石信息的系统发育年代测定。这项研究将产生数据，将提高我们对被子植物生命树中的一个被子植物部分的理解。此外，这项研究将测试已经提出的其他植物群具有类似的间断分布的地理假设，和化石为基础的约会将提供地质时间框架中的分歧和演变的家庭发生。
