Orobanche rapum-genistae Thuill. La Flore des environs de Paris , ed. 2.: 317 ( Thuillier 1799 ). LECTOTYPE . — France . “Environs de Paris ”, s.d., J. L. Thuillier s.n. (lecto-, designated here, G [ G00396694 ]photo!) ( Fig. 4 ) . NOTE Beck-Mannagetta (1930) reports: “vidi spec. orig. in Herb. Petrop.” The study of the herbarium samples preserved in LE resulted in only one specimen from Paris [LE01148356] photo! coming from the herbarium of Ledebour which has no direct connection with Thuillier and therefore cannot be considered original material. A specimen was found in P[P04384660]photo! with a label bearing the name of the species and the indication “Herb. Thuillier” but without place of collection and date. Another specimen has been found in G[G00396694]photo! that the imprinted label authenticates as coming from the Thuillier herbarium. It was so labeled when included in the Delessert collection). This label demonstrates that it is one of the originals used for the Flora of Thuillier. On fact Thuillier’s collections were purchased in 1827 by the banker Benjamin Delessert and transferred to Geneva ( Lasègue 1845 ). In addition, the specimen in G is more abundant, better preserved and more complete. Therefore , we chose the specimen G[G00396694] as the lectotype of O. rapumgenistae Thuill. It includes two complete individuals and the basal portion of another one. The lectotype designated here matches the protologue and corresponds to the current application of the name. GENERAL DISTRIBUTION. — This species occurs from North West Europe to West and Central Mediterranean area including North Africa ( POWO 2022 -onward). Its presence in Tunisia has not been reported by Pottier-Alapétite (1981) and it is considered doubtful in Le Floc’h et al. (2010) and in APD (2022) . We here confirm its occurrence. DISTRIBUTION IN TUNISIA . — Aîn Draham ( Jendouba ), area of ‘Coll des Ruines’ (NW Tunisia ). HOSTS IN TUNISIA . — Observed on Cytisus villosus Pourr. HABITAT. — Within oak forests, on acidic soil of stony slopes. FLOWERING PERIOD. — May to early August. SPECIMEN SEEN. — Tunisia .
