|discussion=<p><i>Azolla mexicana</i> is generally less cold tolerant and has a narrower environmental range than <i>A. caroliniana</i>. Both species are closely related and are similar vegetatively in culture. In the western United States, <i>A. mexicana</i> is often fertile. Distribution in the Great Plains area is tentative and needs further study. In the eastern United States, <i>A. mexicana</i> may have been occasionally introduced.</p>
