Construction of the phylogenetic tree

We constructed the meta-tree of plants from trees stored in Phylomatic (Webb & Donoghue 2005) and using the R package taxize (Chamberlain & Szöcs 2013). To resolve relationships not defined by Phylomatic for Muehlenbeckia and Phoradendron genera, and for the Myrsinaceae family, we used information from the webpage of the Missouri Botanical Garden (http://tropicos.org/). Phylogenetic relationships among Solanaceae (Solanum, Salpichroa, Vassobia, Dunalia, Eriolarynx and Iochroma) were resolved using trees from Levin, Watson & Bohs (2005), Bohs (2007), Weese & Bohs (2007), Olmstead et al. (2008) and Särkinen et al. (2013). Phylogenetic relationships among Celtidaceae, Myrtaceae and Rosaceae were resolved using tree from Song et al. (2001), Lucas et al (2007), and Potter et al. (2007), respectively.
