Notes on the genus Orobanche in Italy: 3. Taxa described by A. Bertoloni
2011
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. mi…
Typification of the name Orobanche canescens C. Presl (Orobanchaceae) with taxonomic notes
2009
The taxonomic status of Orobanche canescens C. Presl (Orobanchaceae), a frequently mistaken species described from Sicily and quite common in the central Mediterranean, is discussed and its name typified. An epitype is also designated as the original material is seriously damaged.
A contribution to the characterization of Ruppia drepanensis (Ruppiaceae), a key species of threatened Mediterranean wetlands
2021
To elucidate the taxonomic status of Ruppia drepanensis Tineo ex Guss. (Alismatales, Ruppiaceae), we performed morphological analysis and DNA barcoding of historical materials (including the lectotype) and fresh samples (including those from a recently discovered population near the locus classicus in Sicily, Italy). We conclude that R. drepanensis is a separate species, closely related to R. spiralis L. ex Dumort., that occurs in temporary inland waters from the western to central sectors of the Mediterranean region. We also highlight the importance of vouchers and the need to link molecular investigations to field, ecological, and morphological investigations.
Nomenclatural notes on the Polycarpon tetraphyllum aggregate (Caryophyllaceae)
2015
Nomenclatural notes on the aggregate Polycarpon tetraphyllum (Caryophyllaceae) are discussed. The names Hagaea alsinifolia, H. polycarpoides, Poycarpon colomense, P. diphyllum, and P. floribundum are typified, respectively, on an iconography by Boccone (lectotype), and specimens preserved in PAL (neotype), JE (lectotype), MA (Herbarium Cavanilles, lectotype), and COI (Herbarium Willkomm, lectotype). For the nomenclatural purposes, the names P. bivonae (nom. nov. pro P. polycarpoides), P. herniarioides (holotype in K), P. peploides (nom. superfl. et nom. illeg. according to the Arts. 52.1 and 52.2 of the ICN), P. polycarpoides subsp. catalaunicum (holotype in BC), and P. rotundifolium (holot…
Typification of the names Anethum pusillum and Meum segetum (Apiaceae)
2022
Recent works (Jimenez-Mejias & Vargas 2015, Frankiewicz et al. 2021) have improved our knowledge about systematics and phylogeny of the Apiaceae: in detail, the Authors suggested the opportunity to merge several genera within Anethum Linnaeus (1753: 263), namely: Foeniculum Miller (1754: [513]), Ridolfia Moris (1841: 43), Pseudoridolfia Reduron, Mathez & S. R. Downie in Reduron et al. (2009: 496), and Schoenoselinum Jimenez-Mejias & Vargas (2015: 75). In this framework, we think that it is important to typify the names Anethum pusillum All. (Allioni 1773: 28) and Meum segetum Guss. (Gussone 1827: 346), both belonging to this “Anethum alliance” (as defined by Jimenez-Mejias &…
Types of names of Orobanche taxa described from North Africa
2013
In the framework of the revision of the genus Orobanche (including Phelipaea) in the Mediterranean area, the original material for 31 names of new taxa described from North Africa by Ball, Battandier, Forsska°l, Maire (partly with Emberger and Jahandiez), Persoon, Poiret and Pomel has been analysed. Typification is discussed, and where necessary types are designated. Accepted names and synonyms of the recognized taxa are given. Three species are illustrated, and one new combination (O. inexspectata) is proposed.
Lectotypification of the Linnaean name Dianthus virgineus (Caryophyllaceae) and its taxonomic consequences
2021
A lectotype is designated for the name Dianthus virgineus. The relationships between D. virgineus, D. caryophyllus var. caryophyllus, and D. caryophyllus var. inodorus are analyzed. Dianthus virgineus is the oldest available name that applies to a species complex that is often referred to as D. sylvestris or a broad circumscription of the cultivated ornamental D. caryophyllus. The taxonomic consequences are discussed, and the need for further studies is highlighted.
A Nomenclatural and Taxonomic Revision of the Senecio squalidus Group (Asteraceae)
2022
Senecio squalidus (Asteraceae) currently includes nine subspecies distributed in North and Central Europe and in the Mediterranean basin. Within this taxonomic aggregate, many species have been described, but research on their nomenclatural types is incomplete. A complete nomenclatural survey of 19 names belonging to this taxonomically critical group was carried out. Fourteen lectotypes are here designated. The nomenclatural analysis, complemented by field investigations in the type localities of the taxa described in the Central Mediterranean, allowed us to accept 10 species. Accordingly, we proposed here a new name and a new missing combination at a specific level: S. aknoulensis and S. c…
