PREMISE OF THE STUDY: Two New World species of Bambusoideae, Arundinaria gigantea and Crytpochloa strictiflora, were investigated in a phylogenomic context. Complete plastome sequences have been previously determined and analyzed for nine bambusoid species that exclusively represent Old World lineages. The addition of New World species provides more complete information on relationships within Bambusoideae. • METHODS: Plastomes from A. gigantea and C. strictiflora were sequenced using Sanger methods. Phylogenomic and divergence estimate analyses were conducted on both species with 23 other Poaceae. • KEY RESULTS: Phylogenomic and divergence analyses suggested that A. gigantea diverged from within Arundinarieae between 1.94-3.92 mya and that C. strictiflora diverged as the sister to tropical woody species between 24.83 and 40.22 mya. These results are correlated with modern relative diversities in the two lineages. • CONCLUSIONS: The two New World bamboos show unique plastome features accumulated and maintained in biogeographic isolation from Old World taxa. The overall evidence for A. gigantea is consistent with recent dispersal, and that for C. strictiflora is consistent with vicariance.
