--><p>C. Mohr’s (1901) report of <i>Polycarpon</i> alsinifolium (Bivona-Bernardi) de Candolle from Alabama was based on misidentification of <i>P. tetraphyllum </i>subsp.<i> tetraphyllum</i>.</p><!--
--><p>The shape of the sepal apex in <i>Polycarpon</i> is varied, with the herbaceous central portion sometimes prolonged beyond the scarious margins into a brief, narrow hood or awn, suggesting an aristate apex.</p>
