Asplenium gulingense was reduced to a synonym of Akiangsuense in the English version of Flora of China. However, the status of both entities has not been investigated rigorously. Phylogenetic analysis of plastid and nuclear sequence data and inference of ploidy level were used to investigate the relationships between these taxa and their putative polyploid origin. Both Akiangsuense and Agulingense were considered to be likely autotetraploid members of the Anormale complex and because of their morphological and phylogenetic similarities, we accept that Agulingense should be treated as a synonym of Akiangsuense in the English version of Flora of China.

Key words: Asplenium kiangsuense, Asplenium gulingense, Chloroplast DNA, pgiC, Systematic position, Polyploid origin
