Hiya distans, a new name for the fern previously called Hypolepis distans
It turns out that Hypolepis distans is not closely related to the other species of Hypolepis. This blog post sets out the case for instead calling it Hiya distans.
I'd appreciate feedback on whether people think we should adopt this change on iNaturalist. I recommend we do wait until/if it is picked up by the New Zealand Plant Names Database
