  1. New York State Department of Environmental Conservation (DEC) Regulation §193.3, Protected Native Plants, (d) Exploitably vulnerable.
  2. USDA-NRCS-PLANTS includes New York in the range of Pleopeltis polypodioides, but the reference for this (House, H.D. 1924. Annotated list of the ferns and flowering plants of New York State. New York State Museum Bulletin No. 254) mentions only that the "gray polypody, or tree fern (Polypodium polypodioides) (L.) Watt, has been found on driftwoud on the Staten Island shore, although its natural range is from Virginia southward."
