Phylogenetic representation of the 170 currently recognized species ofViburnum. Branches in bold represent the 90 species and evolutionary relationships recovered in Clement and Donoghue [15]. Thin branches are those species added to the study of Viburnum in this paper, and dashed branches are Viburnum species that have yet to be sampled. These species are placed at the base of the named clade to which they are expected to belong based on previous taxonomic and morphological studies. Species names in green are those that are currently used in the horticultural industry, and species marked by an asterisk were sampled in Fazekas et al. [4] and in CBOL Plant Working Group [5]. Informal clade names (following [15]), and the number species sampled in this study followed by the total number of species assigned to the clade, are provided. Abbreviations are as follow: CO-Coriacea, LA-Lantana, LE-Lentago, LO-Lobata, LU-Lutescentia, MO-Mollodontotinus, OP-Opulus, OR-Oreinodontotinus, PS-Pseudotinus, PT-Punctata, SA-Sambucina, SO-Solenotinus, SU-Succodontotinus, TI-Tinus, UR-Urceolatum.
