Phylogenetic results using nucleotide data. A) Cladogram based on ML analysis (-ln = 473022.24372) of 49 gene sequences from all 43 plastomes sampled (Table 1). Mapped non-homoplastic indels are shown in yellow circles. Numbers in grey circles are indels identified with a more restrictive taxon sampling that were difficult to score across all charophycean green algae and land plants. B) Phylogram based on ML analysis (-ln = 442145.83514) of gene sequences, excluding the two Selaginella species. C) Phylogram based on ML analysis (-ln = 436696.62372) of gene sequences, excluding the three gnetophyte taxa (Ephedra equisetina, Gnetum parvifolium and Welwitschia mirabilis). ML phylogenetic results (-ln = 405904.24872) that excluded Selaginella spp. and gnetophytes were similar in topology to b (not shown). Numbers above the branches are ML bootstrap proportions and numbers below are Bayesian posterior probabilities in this order: all taxa included/Selaginella spp. excluded/gnetophytes excluded/Selaginella spp. and gnetophytes excluded. The asterisk (*) in c indicates the ML bootstrap proportion for Marchantia polymorpha sister to the remaining land plants found in bootstrap analyses that included all taxa, though the best ML tree recovered a sister relationship of M. polymorpha with the mosses Physcomitrella patens and Syntrichia ruralis. Boxes and dashed lines indicate the relative position of monilophytes (light grey) and lycophytes (dark grey).
