| Research Abstract |
We performed phylogenetic analyses of chloroplast and nuclear DNA sequences, with results that hybridation events were involved in diversification of Osmunda, e.g., O. japonica x American O. regalis, O. intermedia (F1, F2, backcrosses)=O. japonica x O. lancea, O. hybrida (4x)=O. japonica x Indian O. regalis, O. mildei (2x)=O. japonica x O. vachellii. Fossil analysis implied that an ancestor to O. regalis, which does not occur in eastern Asia, was distributed in the past in eastern Asia.
