  1. ^: Site counts do not include alignment columns containing no data, and may differ from counts reported in the original literature. k min : theoretical minimum number of loci that would need to be sampled to guarantee that a data set of a given sampling density and taxon count would be decisive for a random, unrooted tree, assuming random distribution of taxon samples. ζ: gene (locus) sampling depth “sufficiency”: kmin normalized to the number of genes (loci) sampled and transformed for scale. ζ < 0 indicates insufficient sampling depth, ζ > = 0 sufficient sampling depth. * denotes a subsample of the Zanne et al. [42] vascular plant “megamatrix”. **: tree enumeration or consensus tree construction terminated prior to program completion
