凤仙花科地区形态多样的家庭与约。1,000个代表，主要分布在旧大陆热带和亚热带。为了了解其成员之间的关系，我们获得了86种凤仙花科植物和5个外类群的叶绿体atpB-rbcL序列。系统发育重建简约和贝叶斯方法提供了一个很好的解决，凤仙花属和Hydrocera之间的姐妹群关系的亲缘关系得到证实。Impatiens的总体拓扑结构得到了有力的支持，并且具有地理结构。凤仙花属植物可能起源于中国南方，并从那里殖民到邻近地区，后来分散到北美，非洲，印度，东南亚半岛和喜马拉雅地区。
Balsaminaceae area morphologically diverse family with ca. 1,000 representatives that are mainly distributed in the Old World tropics and subtropics. To understand the relationships of its members, we obtained chloroplast atpB-rbcL sequences from 86 species of Balsaminaceae and five outgroups. Phylogenetic reconstructions using parsimony and Bayesian approaches provide a well-resolved phylogeny in which the sister group relationship between Impatiens and Hydrocera is confirmed. The overall topology of Impatiens is strongly supported and is geographically structured. Impatiens likely originated in South China from which it colonized the adjacent regions and afterwards dispersed into North America, Africa, India, the Southeast Asian peninsula, and the Himalayan region.
