|discussion=<p><i>Styrax grandifolius</i> is partly sympatric with <i>S. americanus</i>, and molecular data indicate that it is a close relative (P. W. Fritsch 2001). The two species are separated ecologically, with <i>S. americanus</i> occupying lower, moister sites (G. J. Gonsoulin 1974). Hybridization between the two is not apparent.</p><!--
--><p>Some authors have recognized plants with more densely pubescent new shoots, leaves, and inflorescences and shorter pedicels as a distinct taxon, at either the specific or infraspecific level (J. K. Small 1933; A. J. Rehder 1940; G. J. Gonsoulin 1974). The most densely pubescent plants occur in the southernmost portion of the range of the species; intermediates between the two extremes are abundant. The character differences that separate the taxa are here considered taxonomically inconsequential.</p>
