Abstract
Our study provides the first robust nuclear phylogenomic framework for Orchidaceae and an assessment of intragenomic nuclear discordance, plastid-nuclear tree incongruence, and phylogenetic informativeness across the family. Our results also demonstrate what has long been known but rarely thoroughly documented: nuclear and plastid phylogenetic trees can contain strongly supported discordances, and this incongruence must be reconciled prior to interpretation in evolutionary studies, such as taxonomy, biogeography, and character evolution.
