Taxonomic Resources Authors: David C. Tank, Jonathan M. Eastman, Jeremy M. Beaulieu, William K. Cornwell, Peter F. Stevens, Amy E. Zanne Description: 15,363 seed plant genera mapped to higher level clades following classifications of Cantino et al. (2007) and the Angiosperm Phylogeny Group (APGIII, 2009). This table was used to create the topological constraints used in phylogeny reconstruction and to place calibrations used for time-scaling following (Eastman, Harmon, & Tank, 2013).
