--><p><i>Astrolepis sinuata</i> comprises two cytotypes that tend to occupy different ranges and are treated here as subspecies. Sexual diploid populations (<i></i></i>subsp.<i><i> mexicana</i>) are widely distributed in Mexico, but in the flora they are apparently confined to the Davis and Chisos mountains of Texas and to southeast New Mexico. The range of the apogamous triploid (<i></i></i>subsp.<i><i> sinuata</i>) extends from Argentina to the southwestern United States, with a disjunct population in Georgia. Isozyme studies suggest that <i></i></i>subsp.<i><i> sinuata</i> was derived from the diploid <i></i></i>subsp.<i><i> mexicana</i> through autopolyploidy (D. M. Benham 1989).</p>
