Genera in family: ± 200 genera, 3000 species: ± worldwide; some cultivated as ornamental (e.g., Antirrhinum, Mimulus, Penstemon ) or medicinal (Digitalis )
Recent taxonomic note: Recently treated to include only Buddleja, Scrophularia, and Verbascum in CA; other genera moved to Orobanchaceae (Castilleja, Cordylanthus, Orthocarpus, Pedicularis, Triphysaria), Phrymaceae (Mimulus), and Plantaginaceae (= Veronicaceae sensu Olmstead et al.)
