|discussion=<p>Only one species of <i>Peltandra</i>, <i>P. virginica</i>, (with two subspecies), was recognized by W. H. Blackwell and K. P. Blackwell (1974), a treatment followed by some botanists. They synonymized P. luteospadix with <i>P. sagittifolia</i>, based primarily on their contention that no <i>Peltandra</i> species have red fruits, and called that taxon <i>P. virginica</i> subsp. luteospadix (Fernald) Blackwell & Blackwell. All of the specimens cited in their treatment of the genus are <i>P. virginica</i>.</p><!--
--><p>The two species of <i>Peltandra</i> can be distinguished not only on reproductive charactersistics, but also on features of leaf venation. Fossil leaves congeneric with modern <i>Peltandra</i> are known from very late Paleocene through early Eocene deposits of North America. <i>Peltandra</i> is one of two genera of Araceae endemic to the flora area (the other is <i>Orontium</i>).</p><!--
--><p>Species 2 (2 in the flora).</p>
