|discussion=<p><i>Nephrolepis exaltata</i> is occasionally found farther north in the flora, but only as an escape from cultivation. <i>Nephrolepis exaltata</i> is usually confused with <i>N. cordifolia</i> when sterile; the latter species can be distinguished by its distinctly bicolored, adaxial rachis scales. These bicolored scales will distinguish <i>N. cordifolia</i> from all of the other species, even in the absence of other key features.</p>
