Concluding remarks

The critical check of the original sources for the names, often highlighted the need to change the traditional
authorship and place of publication attributed to some scientific names (for instance the names originating from the
work of R. Huter, P. Porta and G. Rigo), respect to what generally accepted (e.g. Euro+Med 2006 onwards, IPNI
2012 onwards, The Plant List 2013 onwards). We also evidenced and corrected validity problems for seven taxa
(Asperula cynanchica var. lactea var. nov., Asperula lactea comb. nov., Biscutella laevigata subsp. raffaelliana
subsp. nov., Ferulago nodosa subsp. geniculata comb. & stat. nov., Limonium tineoi comb. nov., L. usticanum sp.
nov., Noccaea torreana comb. nov.).
Concerning the regions involved in the taxa descriptions, based on the localities cited in the protologue,
Sicily, Sardinia, Abruzzo, Tuscany, Calabria and Puglia host the highest number of localities (352, 205, 109, 109,
105, and 67, respectively). This perfectly parallels the high number of Italian endemics occurring there (Peruzzi et
al. 2014): Sicily, Sardinia, Abruzzo, Tuscany, Calabria and Puglia are also the regions with the highest number of
Italian and regional narrow endemics (Fig. 1). Campania, Lazio and Basilicata show a high number of Italian
endemics, but are underrepresented concerning both loci classici and regional narrow endemics. The regions
hosting the lowest number of localities were instead Umbria, Valle d’Aosta and Molise (7, 5, and 5 taxa,
respectively). Noteworthy, for 74 taxa were originally cited localities from Corsica (France), for 1 taxon from
Malta, for 13 taxa (erroneous) foreign localities outside Italy, Corsica and Malta; finally, for 49 taxa no locus
classicus was cited in the protologue.

As far nomenclatural types are concerned, 640 taxa have a holotype, being correctly described after 1 January
1958 (Art. 40.1 of ICN). The basionyms described before this data resulted 791. Of them, for 347 a lecto- or neo-
typification is available in literature, while for 449 a nomenclatural type is still lacking. Intensive work in the next
