FIGURE 1 in On the monophyly of subfamily Tectarioideae (Polypodiaceae) and the phylogenetic placement of some associated fern genera
FIGURE 1. Phylogenetic relationships of species associated with Tectaria based on plastid DNA markers (atpA, rbcL and trnL-F IGS). A. Bayesian inference (BI) phylogram showing branch lengths; B. Fifty percent majority-rule consensus tree resulting from parsimonious analyses. Maximum parsimony (MP) bootstrap percentages are shown above the corresponding branches and posterior probabilities (PP) are given below the branches. Square brackets indicate nodes that do not appear in the BI phylogram. Dashes indicate MP bootstrap values of less than 50%. Arrows indicate accessions of genera previously segregated from Tectaria, from top to bottom Hemigramma (2 samples), Podopeltis, Quercifilix, Ctenitopsis, Dictyoxiphium and Fadyenia, and Psammiosorus formerly segregated from Arthropteris.

Pictorial comparison of Pyrrosia sarthalensis with allied taxa P. flocculosa, (a) natural habit of P. sarthalensis on the trunk of Rhododendron arboreum, (b) close view fertile lamina with sori, (c) natural habit of P. flocculosa, (d) close view fertile lamina with sori (Photos: Bikarma Singh).
