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. Two new combinations are proposed. Nomenclatural and distribution updates, published elsewhere, and corrigenda are provided as Suppl. material 1.

Endemic, Floristic data, Italy, Nomenclature

The text for the new records should be submitted electronically to Chiara Nepi (chiara.nepi@unifi.it). The corresponding specimen along with its scan or photograph 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).

Peruzzi (FI). – Species new for the flora of Calabria.

This Mediterranean species occurs all across the Italian peninsula, from the north-west to the south-east, but its range was, until now, known to end in Basilicata (Bartolucci et al. 2018), on the northern slopes of the Pollino Massif. The population of Vallone del Rago, consisting of hundreds of individuals scattered over an area of about 1 km, is found, on the contrary, on Pollino’s southern slopes.

Bromopsis stenophylla (Link) LazzerI (Poaceae)

+ LIG: Framura (La Spezia), western slope of M. di S. Agata (WGS84: 44.22375N; 9.57397E), thermophilous shrubs and meadows, 345 m, 12 May 2018, Barberis G., Cibei C. Dagnino D. Di Turi A., Longo D., Marchetti D., Mariotti M.G., Menozzi B.I., Peccenini S., Turcato C. (FI; GE No. 646); Savignone (Genova), eastern slope of M. Moro (WGS84: 44.57264N; 9.00778E), shrubs and meadows along the trail, 830 m, 27 July 2019, Dagnino D. (FI; GE No. 796); Savignone (Genova), south-western slope of M. Brughea, between Castello Nero and Castello Rosso (WGS84: 44.56772N; 8.99264E), xerophytic grasslands and garigues, 597 m, 3 August 2019, Barberis G., Briozzo I., Dagnino D., Leone M., Longo D. (FI; GE No. 753). – Species new for the flora of Liguria.

Bromopsis stenophylla was found in shrubby-herbaceous xerophytic and thermophilous plant communities, under sub-Mediterranean and sub-continental climates. This species occurs in two Special Areas of Conservation: “IT1343415 Guaitarola” (GE 646) and “IT1330213 Conglomerato di Vobbia”. The fragmented distribution in Italy and the recent findings (Lazzeri 2014) suggest that the distribution of this taxon is incompletely known, mainly because of confusions with closely related taxa.

Camphorosma monspeliaca L. subsp. monspeliaca (Chenopodiaceae)

+ LIG: Pietra Ligure (Savona), Rocca delle Fene, presso la vetta (WGS84: 44.154034N; 8.275008E), margine di lecceta, 185 m, S, 12 August 2017, G. Galasso (MSNM); ibidem, 16 August 2018, G. Galasso, det. G. Galasso, E. Banfi (FI, MSNM). – Subspecies confirmed for the flora of Liguria.

Camphorosma monspeliaca was mentioned for Liguria by Penzig (1897) and Gismondi (1949). However, in the past, Liguria included also the Nice area (now Provence, France), from which all the previous reports originated (Bertoloni 1833). Consequently, Bartolucci et al. (2018) believed that the indication for the current Liguria administrative region was a mistake. Instead, the species certainly occurs in this region, on clayey soils along the sloping coastal strip of the western part (e.g., Borghetto Santo Spirito, Pietra Ligure, Finale Ligure).

F. Conti, F. Lucchese, F. Bartolucci

Gelasia villosa (Scop.) Cass. subsp. villosa (Asteraceae)

– MOL. – Subspecies to be excluded from the flora of Molise.

This taxon was reported as occurring in Molise by Lucchese (1995), Fanelli et al. (2001), and Bartolucci et al. (2018). An accurate revision of specimens preserved in URT (Università di Roma Tre) collected by F. Lucchese, led us to attribute them to S. villosa Scop. subsp. columnae (Guss.) Nyman. The nomenclature follows Bartolucci et al. (2020).

Hypericum hirsutum L. (Hypericaceae)

+ CAL: Oriolo (Cosenza), in loc. Scifi lungo la SP154, a ESE della chiesa della Madonna della Neve (WGS84: 39.972495N; 16.442806E), margine di bosco mesofilo, 820 m s.l.m., 11 August 2019, F. Roma-Marzio, P. Liguori (FI). – Species confirmed for the flora of Calabria.

Hypericum hirsutum was reported in Calabria as doubtfully occurring (Bartolucci et al. 2018) based on several records in the so-called area of Alto Ionio Cosentino, published by Vita and D’Errico (1981) and Vita (1989). We confirm the presence of this species in one of these localities.

Leontodon hispidus L. subsp. hyoseroides (Welw. ex Rchb.) Murr (Asteraceae)

+ TOS: Seravezza (Lucca), Alpi Apuane, M. Pelato, sopra le Gobbie, lungo la via delle cave (WGS84: 44.062371N; 10.231210E), pendii rupestri su marmo, 1110 m, 28 June 2016, F. Conti, F. Bartolucci, D. Marchetti (FI, APP Nos. 62876, 62877); Seravezza (Lucca), Alpi Apuane, sopra le Gobbie, nel versante settentrionale del M. Altissimo (WGS84: 44.058955N; 10.23097E), su terra e detriti di marmo, 1130 m, 23 August 2006, D.

Marchetti (APP No. 50323). – Species confirmed for the flora of Toscana.

We confirm the presence of this taxon in the Alpi Apuane, where it was recorded in the past by Fiori (1927). We also observed it in other localities, such as Foce di Pianza, above Carrara (Massa-Carrara); summit ridge of Mt. Pelato, in the group of Mt. Altissimo (Massa-Carrara, Lucca); close to le Gobbie, up to the Passo del Vestito, in the group of Mt. Altissimo (Lucca). As stated by Zidorn (2012), both glabrous and hairy plants sometimes co-occur in some populations.

Pinus halepensis Mill. subsp. halepensis (Pinaceae)

+ SAR. – Status change from naturalized to native for the flora of Sardegna.

The first mention of Pinus halepensis in Sardegna dates back to the explorer Agostino Tagliafico, in 1736 (Arrigoni 1967). Later, Moris (1827) reported the presence of this species, followed by Angius (1851). More recently, Arrigoni (1967) reviewed several historical records supporting the hypothesis of a natural presence of this species in Sardegna. Many other authors considered this taxon native to Sardegna (Arrigoni 2006; Bacchetta 2006; Camarda and Valsecchi 2008), also supported by Pleistocenic fossil pine pollen records (Del Rio and Pittau 1974; Buosi et al. 2016), and by archaeobotanical studies on several Neolithic to Bronze Age (6000–1200 BCE) settlements (Pittau et al. 2012; De Rita and Melis 2013; Buosi et al. 2015; Melis et al. 2017; Pittau et al. 2018). Given this evidence, we support the status change from introduced to native species in Sardegna.

This taxon was recorded for “Bosco Isola” (Lesina, Foggia) by Forte et al. (2002), but then as doubtfully occurring by Bartolucci et al. (2018). The presence of a specimen in the BI Herbarium [Lesina (Foggia), 5 May 1999, leg. F. Pantaleo, det. F. Pantaleo, L. Forte (BI No. 31492)], along with this new finding near Altamura, confirm the presence of this taxon in Puglia.

Polygonum bellardii All. (Polygonaceae)

+ LIG: Serra Riccò (Genova), tra Crocetta d’Orero e Costa Fontana (WGS84: 44.518017N; 8.983647E), scarpata erbosa a bordo strada, 470 m, 13 October 2019, G. Barberis, D. Dagnino, D. Longo, S. Peccenini (GE No. 1480). – Species confirmed for the flora of Liguria.

In Liguria, this species was no longer recorded, despite several historical reports (Bertoloni 1839–41; De Notaris 1844; Raffaelli 1979). The lack of recent records is probably because of confusion with similar common species belonging to the P. aviculare L. group.

Potamogeton nodosus Poir. (Potamogetonaceae)

+ LIG: Sarzana (La Spezia), “IT 1345101 Piana del Magra”, Bozi di Saudino (WGS84: 44.09816N; 9.96347E), lago eutrofico artificiale, 4 m, 1 April 2019, I. Briozzo, D. Dagnino, C. Turcato (GE No. 972). – Species confirmed for the flora of Liguria.

In Liguria, this species was no longer recorded, despite a historical report, i.e., Ottone Penzig’s handwritten notes found on a copy of De Notaris (1844) stored in the library of the University of Genoa. We found P. nodosus inside an artificial lake (Habitat of Community Interest code 3150 “Natural euthrophic lakes with Magnopotamion or Hydrocharition-type vegetation”) within a Special Area of Conservation (IT 1345101 Piana del Magra).

Rosa nititula belongs to the R. canina L. group (Klastersky 1968). In the past, several authors considered this rose as a variety of R. canina and in the recent checklist of the vascular flora native to Italy it is considered as a taxonomically doubtful taxon (Bartolucci et al. 2008).

In Liguria, this species was no longer recorded, despite a historical report, i.e., Ottone Penzig’s handwritten notes found on a copy of De Notaris (1844) stored in the library of the University of Genoa. Ruppia maritima was found in the estuary of the Magra river (Habitat of Community Interest code 1130 “Estuaries”), inside the Special Area of Conservation “IT1343502 Parco della Magra – Vara”. An old specimen (dated 1856) in GDOR Herbarium attests the long-term occurrence of this species in La Spezia area.

When transferred to Tripolium Nees, Aster tripolium L. [1753] is unavailable because the use of the Linnaean epithet in Tripolium would result in a tautonym (Art. 23.4 of the ICN; Turland et al. 2018), but the epithet tripolium becomes again available in the genus Galatella Cass. Unfortunately, Galasso et al. in Bartolucci et al. (2017) forgot to consider this point, so that the combinations are corrected here.
