苔藓藻目包含了热带生态系统中一些物种最丰富、生态优势最强的藻类。然而，该目29个属和数百个种之间的进化关系仍然没有得到很好的解决。由于许多分类群缺乏已知的生殖特征，进化假说根据形态特征的相似性将属归类。为了应用标准的分支分析来加深我们对这一组的理解，这项研究首次全面汇编了苔藓科属的形态、生殖和亚细胞特征。计算机辅助的分支分析最终确定了提供系统发育信息和不提供信息的特征。尽管这项研究中生成的树的拓扑结构预计会随着向该矩阵添加更多数据而发生变化，但许多传统分组和基于分子数据的最近分组都得到了支持。
The Bryopsidales contains some of the most species rich and ecologically dominant algae in tropical ecosystems. However, the evolutionary relationships among the 29 genera and several hundred species of this order remain poorly resolved. Because of a lack of known reproductive characters for many taxa, evolutionary hypotheses grouped genera by similarities in morphological characters. To apply standard cladistical analyses to further our understanding of this group, this study presents the first comprehensive compilation of reported morphological, reproductive, and subcellular characteristics for genera in the Bryopsidales. Computer‐assisted cladistical analyses ultimately identified phylogenetically informative and uninformative characters. Although the topology of the trees generated in this study is expected to change as additional data are added to this matrix, many traditional groupings and recent groupings based on molecular data were supported.
