Fig. 4 50 in Molecular phylogeny of the endemic fern genera Cyrtomidictyum and Cyrtogonellum (Dryopteridaceae) from East Asia
Fig. 4 50% majority rule consensus tree from Bayesian analyses of the three-gene (rbcL, rps4-trnS, and trnL-trnF) data set. Numbered solid circles indicate nodes receiving good support in both Bayesian (PP ≥ 0.90) and Maximum Likelihood (BS ≥ 70) analyses; open circles indicate nodes not receiving good support from either mea- sure; see also Figure 3. Single letters in dark and light grey squares on branches refer to synapomorphic indels in the rps4-trnS and trnL-trnF alignments, respectively. "P" denotes polystichoid ferns; major groups also indicated at right
Fig. 3 in Molecular phylogeny of the endemic fern genera Cyrtomidictyum and Cyrtogonellum (Dryopteridaceae) from East Asia
Fig. 3 Support values for major clades. Each row corresponds to a clade receiving either Bayesian posterior probability (PP)≥ 0.50 or Maximum Likelihood bootstrap support (BS)≥ 50% from single- or multiple-gene data sets. Clades 01–14 were resolved in the three-gene combined analysis and correspond to the numbered nodes in Figure 4. The remaining clades were supported in different single-gene data sets; their composition is indicated in terms of nodes resolved in the combined
Fig. 1 in A new Dominican amber fossil of the derived fern genus Pleopeltis confirms generic stasis in the epiphytic fern diversity of the West Indies
Fig. 1 Holotype of Pleopeltis dominicensis in Miocene Dominican amber (AMNH-DR-ASHS-1). a Pinnatifid leaf fragment including the petiole and several recurved pinnae. The surface of the pinnae is densely covered by overlapping scales. Arrowheads indicate ovate areas

Fig. 2 Consensus chronogram obtained by BEAST analyses of a previously published plastid DNA dataset (Otto et al. 2009). Sister clades of Pleopeltis were collapsed. Time scale shown in million years to present (Ma). Posterior probabilities p ≥ 0.95 were given above branches, whereas confidence age estimate intervals were shown as
