Figure 1.
Four general corolla types in Pedicularis section Cyathophora (Redrawn from Tsoong [14]).
(A) short tubular corolla with a beakless and toothless galea (P. cyathophylloides); (B) short tubular corolla with a toothed galea (P. rex subsp. rex); (C) short tubular corolla with a beaked galea (P. superba); and (D) long tubular corolla with a beaked galea (P. cyathophylla).
Figure 2.
Phylogenies of Pedicularis section Cyathophora inferred from Bayesian, maximum likelihood and maximum parsimony methods using nrITS (A) and the concatenated chloroplast (B) datasets.
Topology shows the majority rule consensus of the Bayesian inference tree, with thicker lines for the posterior support ≥ 0.95. Bootstrap values (≥50) of maximum likelihood/parsimony are indicated above branches. Sample code indicated in the parenthesis after species name and on the species photo is summarized in Table S1.
Figure 3.
Geographical information for studied samples of Pedicularis section Cyathophora.
Detailed collection of sample code is presented in Table S1. The black, green and light blue dash lines separates sample of P. rex subsp. rex, P. thamnophila and the unknown taxon in accordance with the nrITS phylogeny, respectively; and the blue, red and orange dash lines separates samples of P. cyathophylla, P. cyathophylloides and P. superba in accordance with the chloroplast phylogeny, respectively.
Figure 4.
Neighbor-net analysis of Pedicularis section Cyathophora using nrITS (A) and the concatenated chloroplast (B) datasets.
Bootstrap support values for clusters are indicated next to the respective cluster delimitation (dashed lines); monophyly of accepted taxa is annotated in gray, except P. cyathophylloides in the chloroplast network. Scale bar indicates changes.
