|discussion=<p><i>Boykinia aconitifolia</i> from Alabama and Georgia with turbinate capsules and rounded-ovate leaf marginal teeth have been separated as B. turbinata from plants with the more usual urceolate capsules and leaf margins with ovate or triangular teeth. These characters, however, are not closely correlated and it seems better to recognize a single variable species. It is sometimes grown in gardens.</p><!--
--><p>Rafinesque applied the name Therofon napelloides to this species, citing Nuttall’s <i>Boykinia aconitifolia</i> as a synonym. The former is therefore illegitimate.</p>
