  <dc:description>&lt;p&gt;&lt;span&gt;A surge in the collection of exotic&amp;nbsp;&lt;/span&gt;&lt;i&gt;Marsilea&lt;/i&gt;&lt;span&gt;,&amp;nbsp;&lt;/span&gt;&lt;i&gt;M. mutica&lt;/i&gt;&lt;span&gt;,&amp;nbsp;&lt;/span&gt;&lt;i&gt;M. minuta&lt;/i&gt;&lt;span&gt;&amp;nbsp;and&amp;nbsp;&lt;/span&gt;&lt;i&gt;M. hirsuta&lt;/i&gt;&lt;span&gt;&amp;nbsp;in the southeastern United States has prompted the need for updated identification aids. This study provides an annotated key to all water-clover ferns occurring in the region. It describes and illustrates recently documented exotic species and a previously misidentified western introduction. It details the rediscovery of&amp;nbsp;&lt;/span&gt;&lt;i&gt;M. ancylopoda&lt;/i&gt;&lt;span&gt;, presumed extinct, and confirms its identification as the western species&amp;nbsp;&lt;/span&gt;&lt;i&gt;M. oligospora&lt;/i&gt;&lt;span&gt;. Finally it clarifies the status and distribution of two additional western North American species introduced to the southeast,&amp;nbsp;&lt;/span&gt;&lt;i&gt;M. vestita&lt;/i&gt;&lt;span&gt;&amp;nbsp;and&amp;nbsp;&lt;/span&gt;&lt;i&gt;M. macropoda&lt;/i&gt;&lt;span&gt;.&lt;/span&gt;&lt;/p&gt;</dc:description>
