The suprafamilial phylogenetic structure of Malpighiales, one of the largest orders of flowering plants, has been continuously improved over the past decade and the relationships of some subgroups are radically different from pre-molecular classifications. Endress et al.Β provide a first attempt at a floral structural characterization of the currently resolved suprafamilial clades based on comparative studies and use of primary literature. They find that most new suprafamilial clades are well supported by floral structural features, and inner morphological structures of the gynoecium and ovules appear to be especially suitable for characterizing suprafamilial clades within Malpighiales.
