Taxonomie : D'après Evrard & Van Hove (2004): "Most authors have also confused A. microphylla with A. cristata. The first descriptions and illustrations of Martius (1827) and of Mettenius (1847) are indeed probably based on the specimen of Pöppig, collected in Cuba, which belongs to A. cristata, and not on the Chamisso type. The subsequent authors have maintained this confusion."
