Notes

This species has been much misinter- preted; the first author after Brackenridge to characterize it clearly was Maxon (1924) but he did not see the characteristic minute glands. The fern so named by Hooker () is Chingia longissima (Brack.) Holttum. Diels and Christensen confused P. costata with P. pennigera (Forst. f.) Holttum of New Zealand and S.E. Australia; some specimens from Samoa were named Dryopteris transversaria and D. christopherseni by Christensen.
