Polystichum lonchitis (L.) Roth en Asplenium viride Huds. nieuw voor Nederland

In 1978 and 1979 Polystichum lonchitis (L.) Roth and Asplenium viride Huds. were found for the first time in the Netherlands. Both were growing on ditch-sides in the forest ‘Kuinderbos’ at 3-3,5 m below sealevel on calcareous sand. The former occurred in a plantation of Fraxinus excelsior, the latter in a plantation of Picea sitchensis. The nearest localities are in West-Germany, but it is possible that both were transported by western winds from Great Britain.
