|discussion=<p>Recent isozyme analyses (D. M. Benham 1989) indicate that <i>Astrolepis windhamii</i> is an apogamous allotriploid that contains three different genomes, one each from <i>A. sinuata</i>, <i>A. cochisensis</i>, and an unnamed Mexican taxon related to <i>A. crassifolia</i>. Because of this genomic constitution, <i>Astrolepis windhamii</i> tends to bridge the morphologic gap between <i>A. sinuata</i> and <i>A. integerrima</i>, which is itself a hybrid between <i>A. cochisensis</i> and the unnamed Mexican species. Although the features that separate these taxa are subtle, the pinna lobing and scale characteristics of <i>A. windhamii</i> mentioned in the key adequately distinguish them in most cases.</p>
