Species diversity in the Osmundaceae and its phylogenetic analysis

对水仙科植物的系统分析主要从分子系统和区系分析两方面进行。以rbcL为指示剂，对石菖蒲科植物进行了分子系统分析。因此，这个家族的单性被重新评估。基于这样的分子分析，基因分类被修改，尽管结果或多或少与化石和现存材料的比较解剖结果相似。这一结果在悉尼的马列西亚植物座谈会上和泰罗佩亚的报刊上都受到口头谴责。结果表明，肉桂是一种独特的种，肉桂属的地位明显。claytoniana应该从Osmunda中分离出来，并且需要作为Osmunda的一个新的亚属，目前描述为Oniosmunda亚属。在专著研究方面，《世界植物志》中的水仙科植物志已基本完成，《马来植物志》和《中国植物志》（英文版）的研究进展顺利。

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.
