• The Cape Verde palm tree, Phoenix atlantica, holds a high eco- logical and cultural importance within Cape Verde archipelago ecosystem. However, recent studies have raised questions about its distinctiveness, due to its close relationship with and potential origin from its relative, the date palm (Phoenix dactylifera). In this study, employing an expanded sample set and a diverse array of molecular markers, we characterized P. atlantica in Cape Verde and thoroughly investigate its relationship with other Phoenix species. Our findings reveal genetic markers responsible for the differentiation of a P. atlantica genetic pool. Additionally, we uncover evidence of the recent divergence of P. atlantica from northern African date palm populations, suggesting a relatively recent colonization in Cape Verde. These results pose a significant advancement in elucidating the enigma the provenance of P. at- lantica and its connection to P. dactylifera, representing a crucial step forward for Cape Verde nature conservation. Furthermore, our study reveals distinct genetic patterns across various islands in the archipelago. Overall, our results contribute to the intricate historical trajectories and characterization of palm trees in Africa.
