|discussion=<p>D. F. M. Brown (1964) believed that <i>Woodsia oregana </i>subsp.<i> cathcartiana</i> was confined to a single locality on the Minnesota-Wisconsin border. Recent chromosome counts, however, indicate that the tetraploid cytotype of <i>Woodsia oregana</i> is actually more widespread than the diploid <i></i>subsp.<i> oregana</i> (M. D. Windham 1993). The inclusion of western U.S. collections within the definition of this taxon is supported by isozyme data that indicate some plants from Arizona and New Mexico are identical to those collected at the type locality of <i></i>subsp.<i> cathcartiana</i>. In addition to crossing with <i></i>subsp.<i> oregana</i> (see comments above), <i>W. oregana </i>subsp.<i> cathcartiana</i> hybridizes with <i>W. neomexicana</i> to produce sterile tetraploids of intermediate morphology. It also crosses with <i>W. obtusa </i>subsp.<i> obtusa</i>, resulting in the sterile tetraploid W. × kansana Brooks. F. S. Wagner (1987) has shown that <i>W. oregana </i>subsp.<i> cathcartiana</i>, not <i>W. scopulina</i>, hybridizes with <i>W. ilvensis</i> to form the sterile triploid W. × abbeae. Some morphologic evidence suggests that W. × maxonii may be a hybrid between <i></i>subsp.<i> cathcartiana</i> and <i>W. scopulina </i>subsp.<i> laurentiana</i>; this hypothesis requires further testing. The difficulties involved with separating <i></i>subsp.<i> cathcartiana</i> from certain plants of <i>W. plummerae</i> are discussed under that species.</p>
