replacement name
The name of this species was published as Polypodium sylvaticum (Colenso 1845). The original spelling of the specific epithet must be retained (Art. 60.1), even though “sylvaticum” and “silvaticum” are both correct in Latin. The specific epithet “sylvaticum” was used by earlier New Zealand authors, but was changed without explanation to “silvaticum” by Engler & Prantl (1899) when making the new combination in Polystichum, and then followed by Allan (1961) and subsequent authors. The correct spelling of the name is Polystichum sylvaticum.The name Polypodium sylvaticum, as described by Colenso (1845), is illegitimate (Art. 6.4), being a later homonym of P. sylvaticum Schkuhr (1809). Diels (1899) intended to create a new combination in Polystichum by writing “P. silvaticum (Colenso als Polypodium) Diels”. However, Diels’ name is a new name (Art. 6.12a, 6.14), validated by Colenso’s description of Polypodium sylvaticum. Diels was obligated to adopt Colenso’s epithet with the original spelling (Art. 60.1, 60.2), unless he explicitly changed the spelling and stated that he was making a correction; but there is no evidence of such intent. The correct name and spelling for this species is Polystichum sylvaticum Diels in Engler & Prantl, Nat. Pflanzenfam. 1(4): 192, 1899 (‘silvaticum’), not P. silvaticum (Colenso) Diels. (In making this determination we are very grateful for extensive and valuable discussion with John McNeill, Royal Botanic Gardens, Edinburgh).
