Orobanche alsatica Kirschl. is for the first time reported from Crimea with fairly identified specimen-based records; it is an 11th species of the genus confirmed for the peninsula (or a 14th, taking into account one unconfirmed and two very doubtful taxa). It was collected in two localities of the Crimean Foothills. Crimean plants show the flower size somewhat intermediate to a closely related O. bartlingii Griseb.: the corolla length is mostly 17–20 mm, while the stamens are inserted in 3–4 mm above the corolla base. However, we attribute these plants to O. alsatica based on a glandularly pubescent style, as well as the host Peucedanum alsaticum L., typical exactly of this species. In Crimea, the species is confined to plant communities of the class Festuco-Brometea Br.-Bl. et Tx. ex Soó 1947, sometimes transitional to Trifolio-Geranietea sanguinei T. Müller 1962. Orobanche alsatica was recently synonymized with O. buekii A. Dietr., a little-known name published a year earlier and hitherto considered a synonym of O. lutea Baumg.; however, we consider the name O. alsatica requiring proposal to be conserved to avoid disadvantageous nomenclatural changes entailed by the strict application of the principle of priority (Art. 14.1 of ICN).
