Typification of the name Edraianthus siculus (Campanulaceae), endemic species from S-Italy

Edraianthus (Candolle 1830: 130) Candolle (1839: 149) (Campanulaceae Juss.) is a genus of 10–14 species with a centre of distribution in the Balkans, while disjunctions occur in the central and southern Apennines (peninsular Italy), Sicily, and the southern Carpathians (Stefanović et al. 2008). Four species complexes were recognized by Stefanović et al. (2008) and Surina et al. (2009), i.e. “E. tenuifoliuscomplex”, “E. pumilio-complex”, “E. serpyllifolius-complex”, and “E. graminifolius-complex”. The same authors (Stefanović et al. l.c., and Surina et al. l.c.) highlighted the existence of multiple lineages within the current delimitation of Edraianthus graminifolius (Linnaeus 1753: 268) Candolle (1839: 448) s.l. Campanula graminifolia L. [basionym of Edraianthus. graminifolius subsp. graminifolius], the only Linnaean name currently included within Edraianthus, was recently typified by Ferrer-Gallego (2019) who proposed a lectotype (a Barrelier’s image) and an epitype deposited at BEOU (“Campo Imperatore-La Fornaca, Lakušić & Conti s.n., BEOU9637!”). The other subspecies currently accepted, i.e. Campanula graminifolia subsp. siculus (Strobl 1883: 551) Candolle (1839: 448), has not yet been typified and it is here investigated as part of the project Italian Loci Classici Census (see e.g., Peruzzi et al. 2019), and of a line of research developed in the last decade by the Herbarium Flaminio (HFLA, Sapienza University of Rome) that is focused on the amphiadriatic floristic component of the Apennine-Balkan montane dry grasslands (e.g., Di Pietro et al. 2013, 2017, Iamonico et al. 2017).
