Notulae to the Italian native vascular flora: 11

In this contribution, new data concerning the distribution of native vascular flora in Italy are presented. It includes new records, confirmations, exclusions, and status changes to the Italian administrative regions. A new combination in the genus Pilosella is proposed. Nomenclatural and distribution updates, published elsewhere, and corrigenda are provided as Suppl. material 1.

have to be sent to FI Herbarium: Sezione di Botanica "Filippo Parlatore" del Museo di Storia Naturale, Via G. La Pira 4, 50121 Firenze (Italy). Those texts concerning nomenclatural novelties (typifications only for accepted names), status changes, exclusions, and confirmations should be submitted electronically to: Fabrizio Bartolucci (fabrizio. bartolucci@gmail.com). Each text should be within 1,000 characters (spaces included). − CAM. − Species to be excluded from the flora of Campania. According to Bartolucci et al. (2018), this species has not been recently found in Campania and Abruzzo. For both these administrative regions, Tenore (1831) indicated Ajuga reptans L. var. montana Ten., and, on this basis, Casali (1901) reported A. genevensis for Montevergine (Pignatti et al. 2018). However, Tenore's combination is a synonym of A. reptans (Grande 1923).

Floristic records

Arabis caerulea All. (Brassicaceae)
-LIG. -Species to be excluded from the flora of Liguria. This species was reported for Liguria by Penzig (1897), but at the time the administrative region included part of the Maritime Alps, which are currently located in France or in Piemonte. Furthermore, in Liguria the suitable habitats for this species (wet gravels above 1,900 m a.s.l.; Pignatti et al. 2017) Bartolucci et al. (2018) as doubtfully occurring in Umbria, and has been recently reported for this administrative region by Di Natale et al. (2020) based on old herbarium specimens. L. Gubellini, N. Hofmann

Bupleurum stellatum L. (Apiaceae)
-LIG. -Species to be excluded from the flora of Liguria. This species was reported for Liguria by Penzig (1897) and Gismondi (1950) and, based on these records, also by Bartolucci et al. (2018) and Pignatti et al. (2018). Burnat (1906) provided only a few localities for the Maritime Alps, which currently fall in France. The habitat of this species (rocks and siliceous stony ground) is very rare in the Ligurian Alps. We were unable to trace any herbarium specimens in FI, GE, GDOR, and TO.
L This species was recently re-evaluated based on morphological and ecological features (Cano et al. 2017). Glebionis discolor was recently reported also for Puglia (Manni 2020 According to Bovio (2014) and Bartolucci et al. (2018), this subspecies was known, only historically, for Valle d'Aosta. Vaccari (1904Vaccari ( -1911   ; it was also recently reported also for Umbria . A population of about 1 m 2 was found on the steep, south-facing slope of the Maiura doline on a loose and coarse substrate, apparently poor in organic matter. L. Cancellieri, L. Carotenuto This species was reported as doubtful for Lazio by Bartolucci et al. (2018) and as an "almost certainly wrong record" by Anzalone et al. (2010); however, Conti (1995), following Grande (1924), referred to this taxon in an old record by Tenore and Gussone (1842) (sub Cytisus laburnum) from Val Canneto, where we have rediscovered it.

Laurus nobilis L. (Lauraceae)
+ SAR: Status change from naturalized alien to native for the flora of Sardegna. Laurus nobilis is reported by Bartolucci et al. (2018) as casual or naturalized alien in five Italian administrative regions, including Sardegna, whereas in all other regions it is considered as a native species. However, several previous works (Desole 1947(Desole , 1949Arrigoni 2006;Filibeck 2006) highlighted the native status of this species in Sardegna. Indeed, Mediterranean Italy is probably an area of glacial refugia for this frost-sensitive species (Alessi et al. 2019 and references therein). In Sardegna, old individuals grow in gorges and along streams (Filibeck 2006;Bacchetta et al. 2007).
E Phlomis fruticosa is a northern Mediterranean calcicolous species typical of cliffs and garrigues, whose original areal extent is difficult to establish (Pignatti et al. 2018). In Sardegna, this taxon was first reported by Moris (1827Moris ( , 1859. Later it was reported as native by Pignatti (1982) and Corrias and Diana-Corrias (1983). It was then reported as doubtful casual alien by Arrigoni (2013), Bartolucci et al. (2018) and as native of doubtful occurrence by Pignatti et al. (2018). The population found in Taccu (WSG84: 39.513194N, 09.325653E) near S. Nicolò Gerrei (Sud Sardegna) confirms its presence in Sardegna, and certainly it has to be considered native, due to its presence in natural, inaccessible, and rocky contexts.
G This species is cultivated in Italy as an ornamental tree (Mittempergher et al. 1993), and it has been regarded as non-native for the whole country (Banfi and Galasso 2010). However, genetic data (Pepori et al. 2013) suggest a native status for some populations in NW Italy. Bartolucci et al. (2018) consider the species as cryptogenic in Piemonte; it was not recorded for Calabria. We found two large individuals in an area of well-preserved riparian vegetation. We think that U. laevis in Calabria should provisionally have the status of cryptogenic.
