110 genera, ± 2000 species: worldwide, especially temperate. [Angiosperm Phylogeny Group 1998 Ann Missouri Bot Gard 85:531–553; Olmstead et al. 2001 Molec Phylogen Evol 16:96–112] Veronicaceae sensu Olmstead et al. Recently treated to include Callitrichaceae, Hippuridaceae, and most non-parasitic California genera of Scrophulariaceae (except Buddleja, Limosella, Mimulus, Myoporum, Scrophularia, Verbascum). California Maurandya moved to Holmgrenanthe and Maurandella. Limnophila ×ludoviciana Thieret an occasional agricultural weed in rice fields. Hebe ×franciscana (Eastw.) Souster, Hebe speciosa (R. Cunn.) Andersen only cultivated. —Scientific Editors: Robert Patterson, Bruce G. Baldwin.
