|discussion=<p>Species ca. 450 (34 in the flora).</p><!--
--><p><i>Veronica</i> includes many horticultural and weedy plants. Introduction and subsequent naturalization of species is often a possibility. The classification by D. C. Albach et al. (2004b) recognized 13 subgenera within <i>Veronica</i>; this was reduced to 12 by P. J. Garnock-Jones et al. (2007). Of these 12, ten are represented in the flora area. Species in this treatment are ordered by their placement in these subgenera as follows: subg. Pseudolysimachium (W. D. J. Koch) Buchenau (species 1 and 2, type <i>V. spicata</i>), subg. <i>Veronica</i> Linnaeus (species 3–10, type <i>V. officinalis</i>), subg. Beccabunga (Hill) M. M. Martínez Ortega, Albach & M. A. Fischer (species 11–17, type <i>V. beccabunga</i>), subg. Pellidosperma (E. B. J. Lehman) M. M. Martínez Ortega, Albach & M. A. Fischer (species 18, type V. praecox Allioni), subg. Cochlidiosperma (Reichenbach) M. M. Martínez Ortega, Albach & M. A. Fischer (species 19–22, type <i>V. hederifolia</i>), subg. Chamaedrys (W. D. J. Koch) M. M. Martínez Ortega, Albach & M. A. Fischer (species 23–26, type <i>V. chamaedrys</i>), subg. Stenocarpon (Borissova) M. M. Martínez Ortega, Albach & M. A. Fischer (species 27, type <i>V. ciliata</i> Fischer), subg. Pocilla (Dumortier) M. M. Martínez Ortega, Albach & M. A. Fischer (species 28–33, type <i>V. agrestis</i>), and subg. Pentasepalae (Bentham) M. M. Martínez Ortega, Albach & M. A. Fischer (species 34, type <i>V. teucrium</i>).</p><!--
--><p>One of the subgenera, subg. <i>Synthyris</i> (Bentham) M. M. Martínez Ortega, Albach & M. A. Fischer, includes species treated here as the genus <i>Synthyris</i>. Other taxa included in <i>Veronica</i> but sometimes recognized at the generic rank are Pseudolysimachion (W. D. J. Koch) Opiz (D. C. Albach 2008) and Hebe Commerson ex Jussieu (P. J. Garnock-Jones et al. 2007).</p><!--
--><p>Subgenus Pseudoveronica J. B. Armstrong includes <i>Veronica</i> franciscana Eastwood [= Hebe franciscana (Eastwood) Souster] and V. speciosa R. Cunningham ex A. Cunningham [= <i>H. speciosa</i> (R. Cunningham ex A. Cunningham) Andersen], which have been introduced to California as ornamentals that might escape.</p><!--
--><p>Characters known to vary in <i>Veronica</i> are the indument (to densely white tomentose in V. incana Linnaeus), leaf shape, and flower color. Among many of the creeping species of the genus (for example, <i>V. agrestis</i>, <i>V. filiformis</i>, <i>V. hederifolia</i>, <i>V. persica</i>), most leaflike organs on the stems are bracts. The genus also includes a number of ornamentally grown plants, most of them more or less closely related to <i>V. teucrium</i>. They differ mainly in habit and leaf shape and should key out close to <i>V. chamaedrys</i>, <i>V. officinalis</i>, or <i>V. teucrium</i>, but none of them have been reported to persist outside their native range.</p>
