Estimated tree using data from Fernandez et al., (2013)

Our estimated tree generated using data from Fernandez et al., (2013). The tree is based on the ITS DNA region (accession numbers from the supplementary material of Fernández-Mazuecos et al., (2013)) for 29 species of herbaceous plants in the genus Linaria and one outgroup, Antirrhinum graniticum. The tree was estimated using BEAST v2.1.3 (Bouckaert et al., 2014) on the constrained topology from Fernández-Mazuecos et al., (2013). We used a GTR + Γ model of nucleotide evolution, separate partitions for each gene, a relaxed log-normal clock, and birth-death priors.
