APPENDIX 1:
PTERIODOPHYTES (FERNS AND FERN ALLIES) OF THE
MIXEDWOOD PLAINS ECOZONE
This lists the species and hybrid pteridophytes known from at least one verified herbarium voucher from the ecozone. Nomenclature and family order follows that in the Flora of North America (Flora of North America Editorial Committee 1993). Genera are listed alphabetically. Synonyms used in literature appropriate to this area (Britton 1984; 1985; Cody and Britton 1989) are noted in parentheses. Rare species are noted in bold face , with their Nature Conservancy Global (G) rank noted (Oldham 1996), followed by 'RC' to indicate Rare in Canada (Argus and Pryer 1990) and the Endangered, Threatened, Vulnerable or Rare COSEWIC status designation, where appropriate.
