Table 3.
Summary of support values at critical nodes for trees derived from the six phylogenetic analyses (Suppl. material 1: Figs S1–S6). Levels of ML Bootstrap (BS) – and Bayesian Inference (BPP) – support are listed for each of the combined plastid and nuclear, plastid only and ITS analyses, for genera and clades discussed in the text. Rows in bold represent genera. Single accessions are where only one sequence was available for a taxon and comments are included in the table highlighting those conflicting arrangements of taxa between the plastid and ITS analyses. BS and BPP support of 85%/0.95 and higher are considered strong, 65–85%/0.9–0.95 as moderate, and below 65%/0.9 as weak.
