Pourr. ex Lam. is an annual plant species occurring mainly in dry grasslands. The centre of its distribution range is situated in the Mediterranean region, while in Central Europe it has been known only from a few isolated sites in Slovakia and Hungary. In 2016 we discovered this species in open dry grassland of the class on the upper edge of a basaltic andesite quarry near the village of Siltse, Irshavskyi District, Zakarpatska Region, as a new species for the Ukrainian flora. The site is situated in the transitional region between the Pannonian Basin and the Eastern Carpathians. The new locality represents the northernmost recent occurrence of this species.
