Polystrichum spp.

I recently found this fern on the Nature Reserve I work on in Lincolnshire. I have identified it as Hard Shield Fern (Polystichum aculeatum) which appears to be localised within the county and indeed would be a first for the Reserve. However, being fairly new to pteridophytes I stand to be corrected and would appreciate a second opinion.
Many thanks.

  1. It certainly has the characteristics of P. aculeatum – pinnae tapering in width reaching almost down to ground level, pinnules with acute angles and thick ‘stalks’. Usually grows on lime-rich soils.
    That apart, I am mildly puzzled by the apparent absence of any previous years’ fronds around the base of the fern.
