It is a member of the genus Phoenix that constitutes a monophyletic group within the Coryphoideae subfamily, in the palm family. The genus Phoenix is composed of around 14 species whose native distribution is across the South of Europe, throughout Africa, the Arabian Peninsula and South Asia. Species boundaries and relationships are poorly understood owing to the morphological similarities between the species and their ability to hybridise. In this chapter, we review the past and present distribution of Phoenix species and aspects of their reproductive biology and genome dynamics. We then summarise the current state of knowledge of the taxonomy and phylogeny of Phoenix and we outline the main challenges that have so far limited our understanding of the genus' systematics and evolution. We conclude with a roadmap to address these challenges by combining the extraordinary resource of specimens stored in herbarium collections and the power of high throughput DNA sequencing technologies. specialized 076BOTA01 Al-Khayri J.M. ed. edt IRD Jain S.M. ed. edt IRD Johnson D.V. ed. edt IRD 29-54 Cham Springer 2021 https://www.documentation.ird.fr/hor/fdi:010088363 10.1007/978-3-030-73746-7_2 978-3-030-73748-1 [F B010088363] https://www.documentation.ird.fr/hor/fdi:010088363 https://www.documentation.ird.fr/intranet/publi/2023-07/010088363.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2023-07-10 2025-02-24 fdi:010088363 fre
