Abstract: Hybridization, polyploidization, and reticulate evolution are major mechanisms that shape the currentfern diversity. Based on molecular phylogenetic analyses of chloroplast DNA (psbA-trnH, trnG-trnR) andlow-copy nuclear DNA (gapCp) sequences and flow cytometric analysis, we attempt to clarify the originof putative Nephrolepis hybrids and cultivars. Our results confirm the presence of several hybrids, amongwhich Nephrolepis ‘bostoniensis’ and Nephrolepis x hippocrepicis. Two widespread species, Nephrolepisbiserrata and Nephrolepis cordifolia are revealed as the central species in the formation of these hybrids,with Nephrolepis brownii probably occasionally contributing as well. The C-values range indicates thatall analysed Nephrolepis taxa are diploid except for Nephrolepis hirsutula, which is probably a tetraploid.All hybrids and cultivars are found to be diploid or homoploid hybrids. Additionally, our results suggestthat Nephrolepis davallioides might also be a hybrid, possibly of multiple origins.
