Figure 4

Unrooted neighbour-joining tree of the studied Warburgia salutaris based on Nei’s Da genetic distance. Numbers associated with branches indicate bootstrap values (BS) based on 1000 replications. Only BS above 30 are shown. Colours of branches indicate the two genetic groups identified by STRUCTURE. Colour of circles near each label indicate the three main geographic areas as depicted in Fig. 1. Asterisks as in Fig. 2.
