Abstract

Figure S1: Akaike Information Criterion and Bayesian Information Criterion assessing the fitting of Gaussian mixture models to the Ks distribution of both Equisetum hyemale and Equisetum diffusum.; Figure S2: Frequency of duplications among gene families. 5,009 gene trees (including 1000 bootstrap replicates) were reconciled against the species tree. Red corresponds to a high frequency of duplication with low frequency shown in blue. Terminal branches were not visualised.; Figure S3: Inferred age of the whole genome duplication (WGD) event in Equisetum from 14 gene families containing 4 paralogs from 2 putative WGDs. The 95% HPD is shown for each speciation node in blue, with the duplication events in red.; Figure S4: Bayesian analysis of phenotypic and molecular data with the ages of the fossils as tip calibrations and a uniform calibration between 451-385 Ma applied to the root. Blue bars represent the 95% Highest Posterior Density (HPD) interval for each node. Posterior probabilities less than 1.0 are shown next to each node.; Table S1: Taxa sampled for the total evidence and morphospace analyses. Where available, 1C-values are provided as used in the ancestral reconstruction of genome size.
