|discussion=<p>Plants in Florida tend to be depauperate when compared to tropical populations; individual leaves are smaller and plants seldom form dense thickets. Dicranopteris flexuosa appears to be a natural element in the flora (J. R. Burkhalter 1985; R. Moyroud and C. E. Nauman 1989). Plants may not persist very long, however, as evidenced by Alabama and some Florida populations that are no longer extant.</p>
