FIGURE 1. Simplified maximum likelihood phylogeny of the Asia-Pacific clade of grammitid ferns (Polypodiaceae) based on six plastid markers (atpB, rbcL, rps4, rps4-trnS, trnG-R, trnL & trnL-F). Values of maximum likelihood bootstrap support, Bayesian inference posterior probability, and maximum parsimony jackknife support are along/above the branches (Zhou et al. 2023). The genera in blue are newly described here.
