Nomenclatural note. Veronica xalapensis was described from Mexico “prope Xalapa” as an erect, pubescent plant with oblong leaves with crenulate margin and solitary flowers, axillary, on short peduncle. Paris houses a specimen labelled “ Veronica xalapensis ” without further notes (P00670566), whereas the specimen labelled “ Veronica xalapensis ” in Berlin (B-W 00249-050) is numbered “ 2227 ”, “ V. chillensis ” crossed out and a reference to Kunth (1823). The reference to the page in Kunth suggests a later addition of the label. The specimen in Berlin is not considered type material of V. xalapensis since the number “ 2227 ” refers to the notebook of Bonpland and Humboldt (Bonpland & Humboldt 1799 -1804) and a collection from Ecuador. Thus, the Paris specimen is considered the only original material.
