Taxonomie : D'après Evrard & Van Hove (2004): "Most authors have confused A. caroliniana with A. cristata. The origin of this confusion is probably attributable to Mettenius (1847), whose description and illustrations of A. caroliniana are based on a specimen from Mexico, more than likely the type of A. mexicana, and not on the type of Michaux. This paper has been considered as the reference by the subsequent authors, including Mettenius (1867)."
