Abstract: Veronica gentianoides is an attractive species native to the Caucasus, north-eastern Anatolia and the Crimea. It has been cultivated in European botanical gardens and as an ornamental plant since the late 18th century. In the Annotated Catalogue of the Moravian Flora published by Miroslav Smejkal in 1980, this species was reported to be a putative casual which had once been recorded near the town of Telč in the Bohemian-Moravian Highlands. This record has nevertheless generally been ignored, and the species is not mentioned in recent accounts of the Czech flora, including both editions of the Catalogue of alien plants of the Czech Republic. However, herbarium specimens collected at the outskirts of Telč in 1939–1946 and deposited in three different herbaria demonstrate that the cited record is correct. In addition, V. gentianoides was found, most likely as an escape from cultivation, in the town of Vrchlabí in north-eastern Bohemia in 1993. Based on these records, this species has to be regarded a rare casual neophyte in the Czech flora.

Key words: Plantaginaceae, Scrophulariaceae, alien species, casual neophyte, garden escape, Czech Republic, Central Europe
