    Erwin Gruber commented on an older version of Image of Polystichum aculeatum:

    Got to disagree this to be trusted as Polystichum aculeatum (L.) Roth (P. aculeatum (L.) Schott. is illeg. homonym, referring to same species since having same basionym). Do not know the current accepted name for this Polystichum sp. myself.

    Erwin Gruber commented on an older version of n56_w1150:

    This delineation of some Polystichum sp. or close related genus of Dryopteridaceae was titled "Polystichum aculeatum" as were many relatet species in former times. The fern from India is clearly not European P. aculeatum.

    Erwin Gruber commented on "Image of an unknown taxon":

    This image is not appropriate for any (re-) identification, thus might better be omittet. It might show Polystichum aculeatum, but as well e.g. any cultivar of P. setiferum.

    Erwin Gruber commented on "Pinnules - close-up":

    Having some experience with Polystichum sp. (botanist), i may redeterminate the images of this individual to: Polystichum setiferum (Forsk.) Woynar, Soft Shield Fern. I do not see any intermediacy between P. aculeatum and P. setiferum from those images, thus i doubt it to be the hybrid Polystichum x bicknellii.

    Erwin Gruber commented on "Image of an unknown taxon":

    This is clearly Polystichum munitum but not P. lonchitis, thus i disagree to trusted status.

    Erwin Gruber commented on "Image of an unknown taxon":

    This is not Polystichum lonchitis, Northern Holly Fern but P. munitum, (Western) Sword Fern, thus i disagree to trusted status.
