A family of woody and herbaceous plants distributed in tropical to subtropical regions, comprising about 420 species. It includes Strychnos (source of strychnine) and Buddleja (butterfly bush, native to Japan). Under APG IV, Buddleja is sometimes transferred to Scrophulariaceae, but is retained in this family in the broad sense.
