Table 5.
Topology tests among constrained and unconstrained tree topologies for mitochondrial and plastid gene set analyses, respectively. The constraint specifies monophyly of a clade containing Gastrodieae, Nervilieae and Wullschlaegelieae, following the recent nuclear gene coalescent analysis of Pérez-Escobar et al. (2024).
