Nomenclatural note. The only collection of Veronica , which made it to type material, is that of V. mexicana , a distinctive species from the Chihuahua region.It was shown to be related to Siberian and Himalayan species of V. subg. Stenocarpon (Albach 2006) . The species was published byWatson (1888) alongside several other new species based on Mexican plants collected by Pringle but without stating a specific herbarium. Watson was curator at the Gray Herbarium, of which Pringle was collector. Therefore, the specimen in GH is chosen as lectotype and all other specimens of that collection as isolectotypes, including the ones from the Drake and Cosson herbaria in Paris.
