Technical Abstract: The Cocoseae is one of 13 tribes of Arecaceae subfamily Arecoideae, and contains a number of palms with significant economic importance, including the monotypic and pantropical Cocos nucifera, the coconut, and African oil palm (Elaeis guineensis). Using seven single copy WRKY transcription factor genes, we previously inferred a well resolved phylogeny and chronology of the subtribe Attaleinae. In that study, we resolved a monophyletic relict African clade as sister to the American genera, including Cocos. We determined that Lytocaryum is best treated as part of Syagrus, resolved Syagrus sensu lato as sister to Cocos, and presented a novel clade uniting Parajubaea with Butia and Jubaea that is also supported by leaf anatomical data. Branch nodes were congruent with major paleogeographic events. We now extend our sequence analysis across the rest of the tribe, including representatives of Attaleinae, with Roystonea and Reinhardtia as outgroups. Three subtribes, Attaleinae, Bactridinae and Elaeidinae are consistantly resolved with strong support. The monotypic Amazonian Barcella is sister to a monophyletic Elaeis. Acrocomia, Aiphanes, Astrocaryum, and Bactris form well-supported clades. Intergeneric relationships in Bactridinae are less robust and differ from a previous analysis. Several methods of species tree inference are compared, including gene tree parsimony with iGTP, *BEAST, BEST and BUCKy.
