Bayesian 50% strict consensus trees of 44 nrDNA ITS sequences (A) and 45 combined cpDNA rpl16 and rps16 intron sequences (B) from Acronema clade and outgroups. Values on the branches indicate its support (Bayesian posterior probability/ bootstrap value). Those nodes not occurring in the ML strict consensus tree are indicated by pound symbols (#). Short line denotes values < 50%. The tree is rooted with Scandiceae. The names of the clades are identified by Zhou et al. (2008, 2009) and Downie et al. (2010).
