    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.

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