The Staphyleaceae family counts three genera and all have some economic importance. Species of Staphylea L. and Euscaphis Sieb. & Zucc. are cultivated as ornamental trees or shrubs while Turpinia Vent. is grown for timber. However, in western Europe only Staphylea is of relevance.
Molecular phylogenetic data suggest that traditional generic groupings (based on fruit morphology) are polyphyletic and a re-evaluation of the delimitation of the genera is necessary (Simmons 2002). However, this requires confirmation.
