Notes on the genus Orobanche in Italy: 3. Taxa described by A. Bertoloni GIANNIANTONIO DOMINA & PIETRO MAZZOLA Dipartimento di Biologia ambientale e Biodiversita ` , Universita ` degli Studi di Palermo, via Archirafi, 38 90123 Palermo, Italia Abstract Original material of the 12 taxa described as new by Bertoloni has been examined, and typification of their names is discussed. Lectotypes are designated for 11 of Bertoloni’s names, one (O. densiflora Bertol.) had been lectotypified before. Orobanche bicolor Bertol. (non C. A. Mey.) belongs to O. cernua L., O. cruenta Bertol. to O. gracilis Sm., O. stricta Moris ex Bertol. to O. schultzii Mutel, O. thyrsoidea Moris ex Bertol to O. rigens Loisel., O. crithmi Bertol. to O. minor Sm., O. vitalbae Bertol. to O. artemisiae-campestris Gaudin, O. fragrantissima Bertol. to O. lutea Baumg., O. laurina Bertol. to O. hederae Duby, O. yuccae Savi f. ex Bertol. to O. hederae Duby (not to O. minor Sm.), O. centaurina Bertol. to O. litorea Guss. (not to O. artemisiae-campestris Gaudin). O. australis Moris ex Bertol., included by Beck in O. canescens C. Presl, is a good species restricted to Sardinia. O. densiflora Bertol. must not, as is customary, be ascribed to Reuter who republished it later. Keywords: Orobanchaceae, broomrape, nomenclature, typification, taxonomy Introduction The genus Orobanche L. (including Phelipanche Mutel), in Italy, comprises about 30 different species and subspecies (Charter & Webb 1972; Pignatti 1982; Greuter et al. 1989). A fast screening of national and local Italian Floras yielded three times as many accepted names, in Orobanche, than taxa. Having revised the typification of names proposed by Presl, Lojacono, Tineo and Gussone in earlier papers (Domina et al. 2005; Domina & Mazzola 2007, 2009; Domina & Stepanek 2009), we are here considering the 12 species described as new by Bertoloni (1810, 1846). Antonio Bertoloni (1775–1869), when preparing his Flora d’Italia, was assisted by a large number of botanists who sent him dried plant specimens. The Orobanche treatment is no exception: only 3 of the 12 new species in the Flora (Bertoloni 1846) and in the Rariorum Italiae Plantarum (Bertoloni 1810) were described from material collected by Bertolo- ni himself: Orobanche centaurina, Orobanche cruenta and Orobanche fragrantissima. The nine others are based on specimens collected by Salzmann (Orobanche densiflora, from Tanger) or received from Vaucher (Orobanche crithmi, from Liguria), Gussone (Orobanche bicolor, from the Aeolian islands), Moris (Orobanche australis, Orobanche stricta and Orobanche thyrsoidea, all from Sardinia), Savi (Orobanche vitalbae and Orobanche yuccae, from Tuscany), and Bonaparte (Orobanche laurina, from Rome). Beck (1890) and later authors (Pignatti 1982; Greuter et al. 1989; Charter & Webb 1972, etc.) relegated all of Bertoloni’s new names to synonymy. However, the monographic treatments of Beck (1890, 1930), with respect to species described by Bertoloni, are based almost entirely on the study of non-original material; no critical subsequent reas- sessment of their taxonomic disposition has been attempted. Materials and method Bertoloni’s original material is found in his Hortus Siccus Florae Italicae, kept in the Herbarium of the University of Bologna (BOLO).
