|discussion=<p>Marsilea macropoda is introduced in Alabama and Louisiana.</p><!--
--><p>Marsilea macropoda, with its tall, hairy leaves and branched sporocarp stalks, is a striking and distinctive species, worthy of cultivation. It is sympatric with M. vestita 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 M. macropoda with the shorter-stalked sporocarps bearing a superior tooth found in M. vestita.</p>
