Orobanche beauverdii Uhlich & Rätzel (≡ O. gallica Beauverd , nom. illeg. [non O. gallica Gren. ]).

+ Sr: Serbia: [Nišava], Suva Planina bei Nisch [Niš], Nordseite des “Grob” [Devojakci], 28 Jul 1887, Bornmüller (B 10 1201990, as Orobanche laserpitii-sileris Reut. , conf. Beck), rev. Rätzel & Uhlich 7 Feb 2022. – This is the first verified record outside the Alps. We recently gave this taxon (which had been “forgotten” for almost 80 years) a legitimate name ( Uhlich & Rätzel 2021). In that publication, we already listed the herbarium specimen cited above as possibly belonging to O. beauverdii , on the basis of external morphological characters. We confirm our provisional determination by measuring features of the inner corolla: insertion of the stamens 2–3 mm from the base of the corolla (vs 5–7 mm in O. laserpitii-sileris ); hairs on the stamens dense and long up to beneath the anthers, up to 1.4 mm long (weaker and up to a maximum of 0.7 mm long in O. laserpitii-sileris ).
