  abstract = {{I}n this review article, we provide an overview of the status of research on {O}ld {W}orld {E}benaceae with an emphasis on the large genus {D}iospyros. {T}he well-supported phylogenetic tree obtained from nucleotide sequences of multiple regions of plastid genome gave clear insights into the subfamilial classification of {E}benaceae. {I}t supported inclusion of previously recognized genera such as {C}argillia, {G}unisanthus, {M}aba, {M}acreightia and {T}etraclis in {D}iospyros. {E}ndemic {D}iospyros spp. of {N}ew {C}aledonia have multiple origins. {O}ne of these clades has c. 21 species that are morphologically distinct and occupy different ecological niches, but they exhibit low genetic variation, leading to a lack of phylogenetic resolution. {A}nalyses of whole plastid genome sequences did not greatly increase resolution or support for results of our previous plastid analyses. {G}eographical clustering of the individuals against a background of lower sequence divergence of the whole plastid genome could be due to transfer of plastid genomes during hybridization and introgression following secondary contact. {H}owever, > 8400 filtered single nucleotide polymorphisms ({SNP}s) from restriction site associated {DNA} sequencing ({RAD}seq) confirmed species circumscriptions for this clade and produced well-supported phylogenetic relationships, pointing to an early regional clustering among populations and species. {T}his supported allopatric speciation with respect to macrohabitat (i.e. climatic conditions) having had a role in the initial differentiation in the group. {A} later, more rapid radiation involved divergence with respect to microhabitat (e.g. soil preference). {A}lthough chromosome counts indicate that {D}iospyros spp. are consistently diploids with 2n = 30, extensive variation in genome size has been observed, which is due to an increase of repeat elements, including {LTR}/gypsy. {I}n {E}benaceae, pollen is heterogeneous, and palynological synapomorphies are traced at different taxonomic levels. {S}everal new {D}iospyros spp. have recently been identified and documented from {I}ndia, {T}hailand, {C}hina, {A}frica and {N}ew {C}aledonia. {T}axonomic revisions have been completed for the {A}ustralian species, and synonyms are reported for some {N}ew {C}aledonian {D}iospyros spp.},
