Phylogenetic analysis of rbc L and atp B gene sequences from Biebersteinia Stephan (represented by B. orphanidis Boiss.) and from selected taxa of the rosids I and II clades does not support traditional grouping of this genus in Geraniaceae s. s. nor in Geraniales, but indicates strong support for a position nested within Sapindales (as recently delimitated). The rbc L and atp B phylogenies obtained were congruent but differently resolved and do not link Biebersteinia to any other clade within Sapindales. Biebersteinia is on a long branch on its own which, given the particular combination of apomorphic morphological characters, justifies familial status.
