Neighbour-net splits graph illustrating the signal in a morphological matrix with non-trivial signal including representatives of extant and extinct seed plants (matrix used by Friis et al. 2007, being derived from the matrix of Hilton & Bateman 2006). Numbers within brackets, used to highlight accepted and tentative groups, refer to non-parametric bootstrap support (using distance [NJ-BS] parsimony [P-BS], and maximum likelihood [ML-BS] optimality criteria) and posterior probabilities (PP; estimated using Bayesian inference) of corresponding branches in potential phylogenetic trees, i.e. indicate support of alternative, potential clades. Abbreviations: CCG = Coniferales-Cordaitales-Ginkgo clade; V. = Voltziales; BEG = Bennettitales-Erdtmanithecales-Gnetales clade. This picture is linked to my comment to the referenced working paper of Coiro et al. (submitted to Systematic Biology, submitted version published on ResearchGate
