General Description
Notes on delimitation
  • Plantaginaceae is a highly heteromorphic group, including both genera and species with naked flowers and flowers with a double perianth, which is unusual in the Lamiales.
  • Previous studies (summarized by Olmstead et al., 2001 and Tank et al., 2006) revealed the need for recircumscribing this family in a broader sense to include previously recognized families such as Hippuridaceae, Callitrichaceae and a significant part of Scrophulariaceae.
  • The evolutionary relationships (and even their limits) among the families  of Lamiales are still poorly known.  Ongoing phylogenetic studies suggest that some additional changes are expected, including the acceptance of Gratiolaceae as proposed by Rahmanzadeh (2005) and consequently a separate family for the members of Angelonieae.
Number of genera
  • Plantaginaceae have a cosmopolitan distribution and include about 100 genera and 2,000 species.  Of these, 45 genera and 370-400 species are native in the Neotropics.
Status
  • Many genera of the Plantaginaceae are used as ornamentals worldwide, including coral-plant (Russelia), beardtongue (Penstemon), hebe (Hebe) and snapdragon (Antirrhinum L.).
  • Some species of Plantaginaceae have a pantropical distribution, including some weeds, such as Scoparia dulcis L. and Bacopa monnieri (L.) Wettst. 
  • Many species native to the northern Hemisphere are weeds in the Neotropics.  These include species of Linaria, Plantago and Veronica.
  • Nearly half of the genera occurring in the Neotropics are endemic.
General notes
  • The distributional limit of Collinsia Nutt. and Holmgrenanthe Elisens. is adjacent to the Neotropics in southern USA
  • Additionally, Melosperma Benth. and Monttea C. Gay. are endemic to the Central and South Andes in Chile and Argentina, but not present in the Neotropics.

Key differences from similar families
  • The high level of infrafamiliar morphological variation and the many characters shared with other families such as Verbenaceae, Bignoniaceae, Acanthaceae and Scrophulariaceae s.s. make it hard to summarize the morphological differences between Plantaginaceae and other families of the Lamiales.
  • The characters listed above are constant in Plantaginaceae, but they are also present in almost all Lamiales families.

Notable genera and distinguishing features
  • Anamaria V.C. Souza is an endemic, monoespecific genus from the caatinga in semi-arid Brazil.  Despite occurring in a semi-arid region, Anamariaheterophylla (A.M. Giulietti & V.C. Souza) it is an aquatic plant with vegetative branches with floating leaves.  There is no reason to accept the synonimization of Anamaria under Stemodia, as proposed by some authors.  First of all, there is no phylogeny that shows Stemodia to be monophyletic, and any synonymization therefore ought to wait for the results of a study that samples all Stemodia and Anamaria species.  Secondly, there are many morphological characters that distinguish the two genera even though they share a connective splitting the anther thecae (a rare character also shared with Mecardonia).
  • Ildefonsia Gardner is a monoespecific genus, known only from remnant forests in the city of Rio de Janeiro.  Some authors previously synonymised this genus under Bacopa, but since Ildefonsia does not share the main characters of Bacopa, especially calyx and anthers characters, it should be kept separate.
  • Nuttallanthus D.A. Sutton is a recently described genus, which includes some New World species previously placed in Linaria.  One of the species (Nuttallanthussubandinus (Diels) D.A. Sutton ) is native in the Andes and the other two (N. canadensis (L.) D.A.Sutton and N. texanus (Scheele) D.A. Sutton) probably only naturalized in the Neotropics.
  • Philcoxia P. Taylor & V.C. Souza is a recently described genus, which includes three also recently described species, from the Brazilian highlands.  The aerial vegetative parts of these species include only the leaf lamina, which is only a few millimetre in diameter and looks similar to a sand grain.  For this reason the plants are virtually impossible to find in their natural habitat unless they are flowering.  Recent studies additionally showed that Philcoxiaminensis is carnivorous, trapping and digesting nematodes from the soil (Pereira et al., 2012).
  • Veronica L. is present mainly in the northern Hemisphere, with some species naturalized worldwide.  Despite being the most speciose genus in Plantaginaceae, there is only one native species in the Neotropics (V. mexicana S. Watson).
