Abstract

A new natural hybrid fern, Dryopteris×subdiffracta (Dryopteridaceae), is reported from Guangxi, China. Molecular phylogenetic analysis based on DNA sequences from the low-copy nuclear marker and plastid genome revealed respectively that and are parents of the new hybrid, with as the maternal parent. Cytometric analysis of the nuclear DNA content indicated that might be a diploid hybrid. Morphologically, shares a high degree of similarity with from Taiwan, especially in zigzag-shaped rachis and deflexed pinna stalks. However, is distinguishable in the degree of lamina division and shapes of lamina and pinnulets. A comprehensive taxonomic description accompanied by line drawings are provided.
