Nomenclatural note. The second name based on a description of Vaillant is V. squamosa var. vaillantii Rchb. This name was published by Reichenbach (1833 [1830-2]) and mostly associated with V. barrelieri . The specimens encountered in Reichenbach’s exsiccata (e.g., no. 2189 Veronica vaillantii , coll. Fleischmann from “Krain, vom Jeshza nächst Laibach”) certainly belong to V. barrelieri . However, this species does not occur in the area of Paris from where it was described by Vaillant. The description by Reichenbach and Vaillant fits also with V. spicata un- der whose synonymy it should be classified. Rouy (1909) provided the combination V. spicata var. vaillantii for his Flore de France, which caused some confusion whether V. barrelieri occurs in France, but this is not the case. Since Reichenbach probably did not see the herbarium of Vaillant, it is best to lectotypify the name with the illustration in Vaillant et al. (1727) and epitypify it with the specimen from the Vaillant herbarium from Bois de Boulogne to fix the synonymy of the name correctly.
