Plantaginaceae, the plantain family, is a family of flowering plants in the order Lamiales. The type genus is Plantago L..
In older classifications it used to be the only family of the order Plantaginales, but numerous phylogenetic studies, summarized by the Angiosperm Phylogeny Group, have demonstrated that this taxon should be included within Lamiales.
The plantain family as traditionally circumscribed consisted of only three genera, Bougueria, Littorella, and Plantago. However phylogenetic research has indicated that Plantaginaceae s.s. (s.s. = sensu stricto, in the strict sense) were nested within Scrophulariaceae (but forming a group that did not include the type genus of that family, Scrophularia). Although Veronicaceae (1782) is the oldest family name for this group, Plantaginaceae (1789) is a conserved name under the International Code of Botanical Nomenclature (ICBN) and thus has priority over any earlier family name for a family including Plantago. Furthermore, the ICBN does not consider family names published before 1789 to be names eligible for conservation, thus ruling out Veronicaceae. The name Antirrhinaceae has been proposed for conservation over Plantaginaceae. In the meantime, the Angiosperm Phylogeny Group has accepted the name Plantaginaceae. However, Olmstead (2003) has chosen to use the name Veronicaceae, a later synonym.
Plantaginaceae s.l. (s.l. = sensu lato, in the broad sense) are a diverse, cosmopolitan family, occurring mostly in temperate zones. The group consists of herbs, shrubs and also a few aquatic plants with roots (such as the genus Callitriche). Being so diverse, the circumscription of this family is difficult to establish.
