--><p><i>Astrolepis cochisensis</i> is reported to be toxic to sheep (F. P. Mathews 1945). Three cytotypes that occupy different ranges and/or habitats have been identified and are treated here as subspecies. These include a sexual diploid (<i></i>subsp.<i> chihuahuensis</i>) found on calcareous substrates in the Chihuahuan Desert; an apogamous triploid (<i></i>subsp.<i> cochisensis</i>), which inhabits primarily calcareous substrates in the Sonoran, Mojavean, and western Chihuahuan deserts; and an apogamous tetraploid (<i></i>subsp.<i> arizonica</i>), which occupies primarily noncalcareous substrates in southern Arizona. Isozyme analyses suggest that <i></i>subsp.<i> cochisensis</i> is an autotriploid derivative of the diploid <i></i>subsp.<i> chihuahuensis</i> (D. M. Benham 1989). Both the isozymes and substrate preferences of <i></i>subsp.<i> arizonica</i> indicate, however, that it is not a simple autotetraploid and that other taxa remain to be discovered within the <i>Astrolepis cochisensis</i> complex.</p>
