Discussion

Stem indument of Veronica peregrina has been used to distinguish var. xalapensis with a glandular-hairy stem (F. W. Pennell 1935), a variety that seems to be confined to drier places than the type variety. Variety laurentiana is also differentiated from var. peregrina in having a glandular-hairy stem, fleshier leaves, shorter stamens, smaller corollas, and slightly differently shaped capsules (Frère Marie-Victorin and J. Rousseau 1940).

Veronica ×tournefortii Villars [V. officinalis var. tournefortii (Villars) Dumortier] refers to the hybrid between V. officinalis and V. allionii Villars in Europe and is not applicable to any North American plant.

Species ca. 450 (34 in the flora).

Veronica 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 Veronica; 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 V. spicata), subg. Veronica Linnaeus (species 3–10, type V. officinalis), subg. Beccabunga (Hill) M. M. Martínez Ortega, Albach & M. A. Fischer (species 11–17, type V. beccabunga), 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 V. hederifolia), subg. Chamaedrys (W. D. J. Koch) M. M. Martínez Ortega, Albach & M. A. Fischer (species 23–26, type V. chamaedrys), subg. Stenocarpon (Borissova) M. M. Martínez Ortega, Albach & M. A. Fischer (species 27, type V. ciliata Fischer), subg. Pocilla (Dumortier) M. M. Martínez Ortega, Albach & M. A. Fischer (species 28–33, type V. agrestis), and subg. Pentasepalae (Bentham) M. M. Martínez Ortega, Albach & M. A. Fischer (species 34, type V. teucrium).

One of the subgenera, subg. Synthyris (Bentham) M. M. Martínez Ortega, Albach & M. A. Fischer, includes species treated here as the genus Synthyris. Other taxa included in Veronica 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).

Subgenus Pseudoveronica J. B. Armstrong includes Veronica franciscana Eastwood [= Hebe franciscana (Eastwood) Souster] and V. speciosa R. Cunningham ex A. Cunningham [= H. speciosa (R. Cunningham ex A. Cunningham) Andersen], which have been introduced to California as ornamentals that might escape.

Characters known to vary in Veronica 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, V. agrestis, V. filiformis, V. hederifolia, V. persica), 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 V. teucrium. They differ mainly in habit and leaf shape and should key out close to V. chamaedrys, V. officinalis, or V. teucrium, but none of them have been reported to persist outside their native range.
