Network linking rDNA Brachystegia sequences (Neighbor-Net approach – p-distance). The four main clades identified in the different Maximum Likelihood (ML) phylogenetic inferences are delineated with thick coloured lines. The BS support values for these clades are given according to the different ML analyses (ML-N, ML-A, ML-I; one and two partitions; ML-I for ITS1, ITS2, 18S, and 25S). In Miombo Group A, the specimens of B. bakeriana, B. floribunda, and B. spiciformis are clustered together (delineated with the dotted orange line).
