  abstract = {{B}ackground : {R}adiation in some plant groups has occurred on islands and due to the characteristic rapid pace of phenotypic evolution, standard molecular markers often provide insufficient variation for phylogenetic reconstruction. {T}o resolve relationships within a clade of 21 closely related {N}ew {C}aledonian {D}iospyros species and evaluate species boundaries we analysed genome-wide {DNA} variation via amplified fragment length polymorphisms ({AFLP}). {R}esults : {A} neighbour-joining ({NJ}) dendrogram based on {D}ice distances shows all species except {D}. minimifolia,{D}. parviflora and {D}. vieillardii to form unique clusters of genetically similar accessions. {H}owever, there was little variation between these species clusters, resulting in unresolved species relationships and a star-like general {NJ} topology. {C}orrespondingly, analyses of molecular variance showed more variation within species than between them. {A} {B}ayesian analysis with {BEAST} produced a similar result. {A}nother {B}ayesian method, this time a clustering method, {STRUCTURE}, demonstrated the presence of two groups, highly congruent with those observed in a principal coordinate analysis ({PCO}). {M}olecular divergence between the two groups is low and does not correspond to any hypothesised taxonomic, ecological or geographical patterns. {C}onclusions : {W}e hypothesise that such a pattern could have been produced by rapid and complex evolution involving a widespread progenitor for which an initial split into two groups was followed by subsequent fragmentation into many diverging populations, which was followed by range expansion of then divergent entities. {O}verall, this process resulted in an opportunistic pattern of phenotypic diversification. {T}he time since divergence was probably insufficient for some species to become genetically well-differentiated, resulting in progenitor/derivative relationships being exhibited in a few cases. {I}n other cases, our analyses may have revealed evidence for the existence of cryptic species, for which more study of morphology and ecology are now required.},
