Phylogeny of the cytoplasmic inherited chloroplast genome reconstructed using sequences of two marker regions. The shown phylogeny is the mean consensus phylogram of the Bayesian inference of phylogeny carried out with partitioning coding versus non-coding regions. Stars indicate the Bayesian inference P-values ≥ 0.95. G1 to G5 correspond to the haplotype groups of the Lepisorus clathratus complex recognized in Wang et al. [22], whereas numbers indicate the collection number of the specimens of this complex and the Nyingchi Platygyria (grey circles). Circles indicate the type of sporangia: black and grey filled circles indicate specimens with indehiscent sporangia (= Platygyria), whereas open circles indicate specimens with dehiscent sporangia. Species names have been removed in the Lemmaphyllum and Lepidomicrosorium complex because their taxonomy is currently unresolved. Identical to nearly identical topologies (not shown) were recovered in maximum parsimony and maximum likelihood analyses of the same dataset.
