|discussion=<p>Once considered a single species across its range in North America and eastern Asia, <i>Adiantum pedatum</i> is considered to be a complex of at least three vicariant species (<i>A. pedatum</i> and <i>A. aleuticum</i> occur in North America) and a derivative allopolyploid species (C. A. Paris 1991). <i>Adiantum pedatum</i> in the strict sense is restricted to deciduous woodlands in eastern North America.</p>
