Systematic analysis of the Osmundaceae was carried out mostly on molecular systematic and floristic analysis.Molecular systematic analysis of Osmundaceae was made using rbcL as an indicator. As a result, monophyly of this family was re-evaluated. Genetic classification was revised based on such a molecular analysis, though the results were more or less similar to those drawn from comparative anatomy of both the fossil and extant materials. This result was orally resented at the Flora Malesiana symposia at Sydney and in press in Telopea. Oamunsatrum cinnamomea is elucidated to be a distinct species, and generic status for Osmundastrum is evidently indicated. Osmunda claytoniana should be separated from Osmundastrum, and needs to be a new subgenus of Osmunda, which is under description as subgenus Oniosmunda.For monographic studies, manuscript of the Osmundaceae for Species Plantarum, or Flora of the World, is nearly completed, and those for Flora Malesiana and for Flora of China (English edition) is under good progress.

目前对薇菜科植物的系统学研究主要集中在分子系统学和区系分析上，并以rbcL为指标对薇菜科植物进行了分子系统学分析。因此，重新评估了该科的单系性。基于这样的分子分析，遗传分类被修改，尽管结果或多或少与从化石和现存材料的比较解剖学中得出的结果相似。这一结果在悉尼举行的植物群Malesiana研讨会上得到口头报告，并在泰洛皮亚出版。结果表明，肉桂紫丁香（Oamunsatrum cinnamomea）是一个独立的种，明确了紫丁香属的属地位。在专题研究方面，《世界植物植物群志》中的薇菜科手稿已基本完成，《马来植物群志》和《中国植物群植物群志》（英文版）的手稿正在编写中。
