The cosmopolitan Adelanthaceae (incl. Jamesoniellaceae) is a large clade of Jungermanniales that includes some 100 species. Adelanthaceae inhabit a wide range of habitats from the lowlands up into the páramo region of the high Andes. To date, generic concepts of Adelanthaceae are largely based on morphology. Preliminary molecular-phylogenetic analyses indicate that these concepts may be polyphyletic. Based on molecular data (cp trnLtrnF- Region, atpB-rbcL-spacer, rbcL, nrITS1-5.8S-ITS2) we will analyse subdivisions of Adelanthaceae and related clades, and generate monophyletic genus circumscriptions. The new data will also allow to evaluate species concepts in Adelanthaceae and to explore the historical biogeography of Adelanthaceae and related clades based on the fossil record, present-day distributions and molecular sequence variation.

世界性的Adelanthaceae（incl. Jamesoniellaceae）是Jungermanniales的一个大型分支，包括约100个物种。Adelanthaceae栖息在从低地到安第斯山脉的帕拉莫地区的广泛栖息地。迄今为止，Adelanthaceae的属概念主要基于形态学。初步的分子系统发育分析表明，这些概念可能是多系的。基于分子数据（cp trnLtrnF-区域，atpB-rbcL-间隔区，rbcL，nrITS 1 -5. 8 S-ITS 2），我们将分析Adelanthaceae和相关分支的亚分类，并产生单系属circumstellae。新数据还将允许评估Adelanthaceae中的物种概念，并根据化石记录，现今分布和分子序列变异探索Adelanthaceae和相关分支的历史地理学。
