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