|discussion=<p>Species 10 (3 in the flora).</p><!--
--><p><i>Morus</i> nigra Linnaeus has been reported in floras by various authors (J. K. Small 1903, 1933; R. W. Long and O. Lakela 1971), apparently based on dark-fruited <i>M. alba</i>. It is native to Asia, commonly cultivated in Europe for its fruit, and locally naturalized in southern Europe. Occasionally cultivated in North America, it is not known to be naturalized. Because of the similarity to and confusion with <i>M. alba</i>, some American authors place it in synonymy with that species.</p>
