The accepted botanical name of this fern is Thelypteris opulenta as indicated on the Plants of the World Online website. However, in the Singapore Flora checklist and the iNaturalist website, the accepted botanical name is Amphineuron opulentum. The reason is explained in my post in September 2024.
