Premise: Reconciling the use of taxonomy to partition morphological variation and describe genetic divergence within and among closely related species is a persistent challenge in phylogenetics. We reconstructed phylogenetic relationships among Cedrela odorata (Meliaceae) and five closely allied species to test the genetic basis for the current model of species delimitation in this economically valuable and threatened genus. Methods: We prepared a nuclear species tree with the program SNPhylo and 16,000 single-nucleotide polymorphisms from 168 Cedrela specimens. Based on clades present and ancestral patterns ADMIXTURE, we designed nine species delimitation models and compared each model to current taxonomy with Bayes factor delimitation. Timing of major lineage divergences was estimated with the program SNAPP.Results: The resulting analysis revealed that modern C. odorata evolved from two genetically distinct ancestral sources. All species delimitation models tested better fit the data than the model representing current taxonomic delimitation. Models with the greatest marginal likelihoods separated Mesoamerican C. odorata and South American C. odorata into two species and lumped C. angustifolia and C. montana as a single species. We estimated that Cedrela diversified in South America within the last 19 million years following one or more dispersal events from Mesoamerican lineages. Conclusions: Our analyses show that the present taxonomic understanding within the genus obscures divergent lineages in C. odorata due in part to morphological differentiation and taxonomic distinctions that are not predictably associated with genetic divergence. A more accurate application of taxonomy to C. odorata and related species may aid in its conservation, management, and restoration efforts.

This paper reviews the biogeography and ecology of the family Meliaceae and maps many of the clades. Recently published molecular phylogenies are used as a framework to interpret distributional and ecological data. The sections on distribution concentrate on allopatry, on areas of overlap among clades, and on centres of diversity. The sections on ecology focus on populations of the family that are not in typical, dry-ground, lowland rain forest, for example, in and around mangrove forest, in peat swamp and other kinds of freshwater swamp forest, on limestone, and in open vegetation such as savanna woodland. Information on the altitudinal range of the genera is presented, and brief notes on architecture are also given. The paper considers the relationship between the distribution and ecology of the taxa, and the interpretation of the fossil record of the family, along with its significance for biogeographic studies. Finally, the paper discusses whether the evolution of Meliaceae can be attributed to 'radiations' from restricted centres of origin into new morphological, geographical and ecological space, or whether it is better explained by phases of vicariance in widespread ancestors, alternating with phases of range expansion.

Two new species of Aglaia from Indonesia are described, Aglaia monocaula restricted to West Papua, and Aglaia nyaruensis occurring on Borneo (Kalimantan, Brunei, Sabah and Sarawak). A phylogenetic analysis using nuclear ITS and ETS, and plastid rps15-ycf1 sequence data indicates that the two new species of Aglaia are also genetically distinct. Aglaia monocaula belongs to sectionAmoora, while A. nyaruensis is included in section Aglaia. A dichotomous key, drawings and three-locus DNA barcodes are provided as aids for the identification of the two new species of Aglaia. In addition, the geographic range of Aglaia mackiana (section Amoora) is expanded from a single previously known site in Papua New Guinea to West Papua, Indonesia.
