Nomenclatural note. Veronica pseudoarvensis is stated by Tineo (1846) to differ from typical V. arvensis in larger, intensive blue corolla (equalling the calyx, not smaller and pale blue to white) and pedicel elongated to the length of the calyx (not subsessile). Both characters can be seen in V. arvensis occasionally, and especially the second character can be easily seen in the specimens of Tineo. The specimens resemble in these respects V. sartoriana from Greece, which additionally differs from V. arvensis in glandular indumentum and a strongly emarginate capsule. The indumentum has not been reported by Tineo (1846) and cannot be seen in scanned specimens, but the capsules are, in fact, deeply emarginate. Thus, there seems to be some kind of continuous variation between both species, which needs to be investigated in further detail. Since the types are expected to be in PAL, we chose the specimen in PAL with correct place and time as lectotype and the specimen from FI as isolectotype. The latter specimen bears no direct indication of the date, other than given to the herbarium in 1849. Its status is, therefore, debatable. The specimen in P corresponds in all characters to those two specimens, bears the same handwriting and is also from Palermo but has no indication of the collection date, and the label is identical to other specimens in PAL. It belongs to the herbarium of Adrien de Jussieu.
