Nomenclatural note. Thuillier (1790) published the name V. ocymifolia based on Vaillant et al. (1727: 202) “16. Veronica minor annua, ocymi caryophyllati folio, subtus rubro, flore caeruleo”. No specimen labelled V. ocymifolia by Vaillant, nor a specimen of V. praecox , to which the plants presumably belong of Vaillant, was found in the herbarium in Paris. However, authentic material from Thuillier labeled V. ocymifolia is available in Paris and Munich. These plants correspond to V. praecox . The character distinguishing these from typical V. praecox is the reddish leaves. However, reddish leaves are common in many species of Veronica and not sufficient to name a new species. They are designated as neotypes here since it is not clear whether these specimens were collected before 1790.
