基于rbcL序列的系统发育树支持目前的分类，即Matonia科及其属Matonia和Phanerosorus均被视为单系类群。Phanerosorus是岩生植物，有下垂的羽状叶子，而Matonia喜欢暴露的山顶，有带柄的叶子。野生木和野生木幼株的形态检查显示，叶片有相当大的异质性，从单叶到一或两叉，再到三分叶，具果穗。虽然成熟植株的叶片在Matonia和Phanerosorus之间差异很大，但M. pectinata的幼叶与Phanerosorus major的幼叶相似，并且在较小程度上与老叶相似。这些数据以及现有的化石和形态学证据可能表明，Phanerosorus的羽状叶可能是通过幼体发育，来自于像化石Matoniaceae和现存Matonia的有柄叶。
Phylogenetic trees based on rbcL sequences support the current classification that the Matoni- aceae and its genera Matonia and Phanerosorus each are treated as monophyletic groups. Phanerosorus is litho- phytic and has pendulous, pinnate leaves, while Matonia prefers exposed mountain tops and has pedate leaves. A morphological examination of wild juvenile plants of Matonia pectinata and M.foxworthyi shows con- siderable leaf heteroblasty from simple to once or twice forked and to tripartite with pectinate pinnae. Although the leaves of mature plants differ greatly between Matonia and Phanerosorus, the juvenile leaves of M. pectinata are similar to the juvenile leaves, and to a lesser extent the old leaves, of Phanerosorus major. These data along with available fossil and morphological evidence may suggest that the pinnate leaves of Phanerosorus are derived, perhaps via paedomorphosis, from pedate leaves like those of fossil Matoniaceae and extant Matonia.
