RAxML bootstrap tree based on nuclear ribosomal (ITS) and plastid (matK, rbcL, trnL-F) DNA sequence data resolving Keraunea within the Ehretiaceae. Node labels indicate nodes with bootstrap support values above 50. Inset phylogram (bottom left) indicates branch lengths. Outgroup taxa from representatives of other Boraginales families are in light grey. Illustrations are (top to bottom): Keraunea, Halgania, Ehretia, Bourreria, Rochefortia and Tiquilia.
