--><p>Variety texanum is tetraploid; <i></i>var.<i> drummondii</i> is both diploid and tetraploid. The tetraploid race of <i></i>var.<i> drummondii</i> is most likely autopolyploid; origin of <i></i>var.<i> texanum</i> has not been determined. The two taxa intergrade and do not appear to warrant species status.</p>
