“…The prolonged isolation and high geological diversity created a wide range of habitats rich in endemic species, particularly on its mountain massifs, where the insularity is strengthened by the altitude and diversity of terrains (MÉDAIL & QUÉZEL, 1997). The Sardinian flora consists of 2408 taxa including 2295 species (CONTI & al., 2005) 168 of which are exclusive endemics (BACCHETTA & al., 2012b).…”

“…Species selection was made following the policy species listed in Habitat Directive and the priority list of the exclusive taxa of Sardinia (Bacchetta et al 2012b), according to the "regional responsibility" criterion. In addition, considering the most threatened priority habitats (sensu Habitat Directive) at the regional level, three structural trees of these habitats were selected.…”

“…Consequently, "priority lists" should be created in order to identify the target species for conservation measures, as the conservation of biodiversity occurs via the implementation of policy with only limited resources (Balmford et al 2005). In this sense, several authors establishing regionallevel priorities identified the "regional responsibility" as the first-order priority at the local level (Gauthier et al 2010;Bacchetta et al 2012aBacchetta et al , 2012bSchatz et al 2014). In this context, conservation efforts in species-rich areas, such as Sardinia, must be oriented towards the policy species and, at the same time, they must consider the criterion of regional responsibility.…”

The in situ conservation activities carried out in the last 10 years on endemic and threatened Sardinian vascular flora were analysed. Monitored species were selected following the policy species (listed in the Habitat Directive) and following the regional responsibility criterion. A monitoring scheme, with three levels of intensity, was applied and economic costs of the monitoring activities were analysed. In the 10-year long field work, 49 taxa corresponding to 50% of policy species and to 22.5% of the Sardinian endemics were monitored. The Sulcitano-Iglesiente sector showed the highest number of monitored taxa (20), whereas the Gennargenteo sector showed the highest number of populations monitored (32). A variation of the relative importance of the three levels of monitoring has been detected and most of the protocols showed a high level of intensity and complexity (90%). Plant-monitoring programmes have been considerably intensified over time with an increase in the total costs; the most important cost was the staff. The economic resources increased significantly over time, both in personnel and travelling costs. Consequently, in order to ensure sufficient support to in situ conservation activities in Sardinia, increased public funding will be necessary.

“…36.1(c)) because it was merely cited as a synonym in Fiori (1904). But subsequently, it was widely used by Italian botanists to define this nothotaxon at the species level (Beguinot & Vaccari 1927, Arrigoni 1972, Bacchetta et al 2012. In this note we start from the Levier's name (handwritten on the label of the type material), we give a diagnosis and indicate the holotype to validate the name C. forsythiana.…”

“…388 that was distributed in the Flora Italica Exsiccata (Fiori et al 1906), but that sample reported is C. filiformis, without any mention of the hybrid taxon. However, the name is actually in use, because it was accepted (though not validly published) in a recent list of Sardinian endemic plants (Bacchetta et al 2012). This taxon has a scientific interest because it is one of the few examples of incipient homoploid hybrid speciation between two narrow endemic species: the parental species are exclusive of Sardinia, C. horrida growing only in the north-western part of the island and C. filiformis in the central-eastern part, and overlapping only at the Tavolara island (Pisanu et al 2011, Mameli et al, in press).…”

Two individuals morphologically intermediate between Centaurea horrida Badarò (1824: 367) and C. filiformis Viviani (1825: 6) were collected by Charles Immanuel Forsyth Major on 26 May 1885 at Tavolara Islet, Italy (FI!): these samples were published by Fiori (1904) and later reported in Arrigoni (1972) as two different hybrids: “C. superfiliformis × horrida Levier” and “C. superhorrida × filiformis Levier”. As annotated on the label by Emile Levier, the material deposited in FI shows that the morphology of the two hybrids is very different and only the one named by Fiori as “C. superfiliformis × horrida Levier” was labelled as C. forsythiana Levier (Fig. 1). This sample is morphologically similar to the individuals of a hybrid population we discovered in the same site in the Tavolara Islet (Timone), on limestone, as reported by Fiori (1904). The hybrid named “C. superhorrida × filiformis Levier” by Fiori (1904) was collected by Forsyth Major in a different site (Bocchetta) on granite, and has never been recollected afterwards. For the matter of this note, this is not a problem since, according to Article H.4.1 of the International Code of Nomenclature (McNeill et al. 2012), all the hybrid variants originated from the same parental species, as far as considered nothotaxa (Art. H.3.1), should bear the same name.
