Fig. 1 in Taxonomic revision of Australian Erythrophleum (Fabaceae: Caesalpinioideae) including description of two new species

Fig. 1. Maximum-likelihood tree of aligned ribosomal sequences of Erythrophleum, rooted with Pachyelasma tessmannii. Nodal support values are bootstrap support values (RAxML) followed by posterior probabilities (MrBayes). Indel positions in ITS1 are indicated by grey bars, and numbered as in the text (see Results). Three clades (E. arenarium, E. chlorostachys and E. pubescens) match species designations from morphology, as described in the taxonomy section. Within the sampled Erythrophleum taxa, the three Australian species form a clade, and there is weak support for a sister relationship between E. arenarium and E. chlorostachys. The intraspecific variation within E. pubescens lacks support, and is not considered taxonomically informative. Sample names indicate species, state, location, collector and number, and GenBank or ENA accession number.
