FIGURE 3 in Hundreds of nuclear and plastid loci yield novel insights into orchid relationships.

FIGURE 3. Summary of nuclear–plastid phylogenomic incongruence based on PACo analysis across different taxonomic levels between clades of Epidendroideae based on nuclear and plastid ML trees. Conflicting positions between orchid (A) genera, (B) subtribes, and (C) tribes. Association of terminals found to be incongruent and placed with robust support in nuclear and plastid trees are highlighted in bold and red. Pie diagrams at nodes represent quartet support values. Likelihood bootstrap support (LBS) percentages at nodes are 100 unless shown otherwise (LBS <85 are highlighted in red). Photos: Representatives of three strongly conflicting groups in the orchid family (Epidendreae: Pleurothallis perryi.; Catasetinae: Cycnoches guttulatum with its potential orchid bee pollinator (Euglossa aff. cybelia); Angraecinae: Angraecum rutenbergianum).
