Phylogenetic informativeness, signal and noise of nuclear and plastid markers. Pie charts show the relative probabilities of correct (grey), incorrect (black) and polytomous (white) resolution of nuclear and plastid datasets across a range of individual nodes (N1-N7) within the phylogeny of H. sect. Cornidia and its close relatives. The probability of nuclear markers recovering incorrect resolutions is lower than their respective probability of recovering correct resolutions across all nodes. In contrast, plastid markers show higher probabilities of recovering incorrect than correct resolutions at the deepest nodes (N5 to N7; a). Per site PI across time of the individual nuclear and plastid regions (b). Red circles indicate BS <85 for internal nodes
