[Classified as historically present in Nfld. (Bouchard et al., 1991), Equisetum hyemale subsp. affine was relocated at the mouth of Fischells Brook, swNfld., by the NFRPP in 2000. Previously, it was known from only one 1910 specimen, collected at Middle Birchy Pond, wNfld. However, the identity of the 1910 specimen is in doubt, as Hauke (1963) believes the specimen should be referred to the hybrid Equisetum Xtrachyodon (listed here as E. Xmackaii). The species complex Equisetum hyemale is circumboreal in distribution. The specific epithet should be spelled 'hyemale' rather than 'hiemale;' likewise, 'prealtum' should be used rather than 'praealtum.']

[Athyrium alpestre var. americanum, classified as rare in Nfld., is found in late snowbeds and quartzite slopes in the Long Range Mts. (Bouchard et al., 1991). There is much confusion about the proper citation of this species. The type of Athyrium alpestre (Flora North America, Vol. 2:256 (1993), is reported to be a specimen of Athyrium felix-femina (L.) Roth ex Mertens, making it a nom. illeg. Kartesz & Gandhi (1995) state that the next available legitimate name is Athyrium distentifolium Tausch ex Opiz. Other authors remain unconvinced by this argument and, as the current authors do, follow Kato's treatment in FNA (1993) until the nomenclature question is explored further. The authority for Athyrium alpestre was listed in FNA (1993) as (Hoppe) Clairville, published in 1917, but Rylands ex T. Moore published this name in 1857, making Clairville's name superfluous.]
