Phylogenetic relationships of Waltheria generated by Bayesian inference based on concatenated nuclear (ITS) and plastid (matK and ndhF) regions. The bar with horizontal lines represents W. sect. Stegowaltheria, and with vertical lines, W. sect. Waltheria sensu Schumann (1886). Numbers above the branches are PP values. The new species, W. marielleae, is highlighted in bold.
