|discussion=<p><i>Marsilea macropoda</i> is introduced in Alabama and Louisiana.</p><!--
--><p><i>Marsilea macropoda</i>, with its tall, hairy leaves and branched sporocarp stalks, is a striking and distinctive species, worthy of cultivation. It is sympatric with <i>M. vestita</i> over much of its range, and individuals that appear to be hybrids have been collected in Blanco, Brazos, and Kleberg counties in Texas. These plants combine the large hairy leaves of <i>M. macropoda</i> with the shorter-stalked sporocarps bearing a superior tooth found in <i>M. vestita</i>.</p>
