  abstract = {{B}ackground and {A}ims {T}he geographical origin and evolutionary mechanisms underpinning the rich and distinctive {N}ew {C}aledonian flora remain poorly understood. {T}his is attributable to the complex geological past of the island and to the scarcity of well-resolved species-level phylogenies. {H}ere, we infer phylogenetic relationships and divergence times of {N}ew {C}aledonian palms, which comprise 40 species. {W}e use this framework to elucidate the biogeography of {N}ew {C}aledonian palm lineages and to explore how extant species might have formed.{M}ethods {A} phylogenetic tree including 37 {N}ew {C}aledonian palm species and 77 relatives from tribe {A}receae was inferred from 151 nuclear genes obtained by targeted sequencing. {F}ossil-calibrated divergence times were estimated and ancestral ranges inferred. {A}ncestral and extant ecological preferences in terms of elevation, precipitation and substrate were compared between {N}ew {C}aledonian sister species to explore their possible roles as drivers of speciation.{K}ey {R}esults {N}ew {C}aledonian palms form four well-supported clades, inside which relationships are well resolved. {O}ur results support the current classification but suggest that {V}eillonia and {C}ampecarpus should be resurrected and fail to clarify whether {R}hopalostylidinae is sister to or nested in {B}asseliniinae. {N}ew {C}aledonian palm lineages are derived from {N}ew {G}uinean and {A}ustralian ancestors, which reached the island through at least three independent dispersal events between the {E}ocene and {M}iocene. {P}alms then dispersed out of {N}ew {C}aledonia at least five times, mainly towards {P}acific islands. {G}eographical and ecological transitions associated with speciation events differed across time and genera. {S}ubstrate transitions were more frequently associated with older events than with younger ones.{C}onclusions {N}eighbouring areas and a mosaic of local habitats shaped the palm flora of {N}ew {C}aledonia, and the island played a significant role in generating palm diversity across the {P}acific region. {T}his new spatio-temporal framework will enable population-level ecological and genetic studies to unpick the mechanisms underpinning {N}ew {C}aledonian palm endemism.},
