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.

Endemic taxa, Floristic data, Italy

The text for the new records should be submitted electronically to Lorenzo Lastrucci (lorenzo.lastrucci@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).

Aconitum anthora L. (Ranunculaceae)

+ TOS: Villa Collemandina (Lucca), Pania di Corfino (WGS84: 44.197804N, 10.383953E), lungo la cresta rocciosa sopra la località “La Bandita”, 1550 m s.l.m., 17 August 2020, E. Cheli (FI). − Species new for the flora of Toscana.

Ajuga genevensis L. (Lamiaceae)

− 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).

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) are extremely reduced. No herbarium specimens were found in FI, GE, GDOR, and TO.

+ MAR: Porto Recanati (Macerata), loc. Scossicci, stagni artificiali ad uso venatorio (“guazzi”) presso la foce del Fiume Musone (WGS84: 43.467787N, 13.632456E), c. 3 m, 13 October 2020, L. Gubellini, N. Hofmann, S. Tonelli (FI, PESA); dintorni di Fano, luoghi acquitrinosi nell’alveo del Metauro presso la foce, suolo prevalentemente argilloso, 18 September 1963, leg. et det. A.J.B. Brilli-Cattarini (PESA, under the name Scirpus maritimus L. β macrostachys W.). – Species confirmed for the flora of Marche.

According to Bartolucci et al. (2018) and Di Natale et al. (2020), B. glaucus was known so far for Marche only as historical record.

L. Gubellini, N. Hofmann, S. Tonelli

Bolboschoenus maritimus (L.) Palla (Cyperaceae)

+ UMB: Tuoro sul Trasimeno (Perugia), Punta Navaccia, tra i massi dell’argine del lago nei pressi del Campo del Sole (WGS84: 43.194102N, 12.079322E), ca. 255 m, 5 October 2020, N.Hofmann (FI; PESA). – Species confirmed for the flora of Umbria.

This species was recorded by 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.

Andreatta (VER No. SA525) – Species confirmed for the flora of Veneto.

Chenopodium pedunculare was only recently re-established (Iamonico and Mosyakin 2018), and has been poorly known from Veneto: its presence was witnessed by Bertoloni, who found it in Brondolo (Chioggia, Verona) and mentioned it at “Fossa Clodia ad viam della Madonna a Prof. Naccario”. Other than there, the author also described this species only in Sarzana (La Spezia; Bertoloni, 1837). Several specimens have been found in San Martino Buon Albergo (Verona), by the side of a country lane near a big barn, on nitrophilic soil.

Hyparrhenia sinaica (Delile) Llauradó ex G.López (Poaceae)

+ LAZ: Alvito (Frosinone), Fossa Maiura (WGS84: 41.715940N, 13.721343E), gariga sul versante esposto a sud di una grande dolina, 771 m, 26 May 2020, L. Cancellieri, L. Carotenuto (FI). – Species new for the flora of Lazio.

Hyparrhenia sinaica is a SW-Steno-Mediterranean species, reported in peninsular Italy for Toscana, Puglia, Calabria, and for Sicilia and Sardegna (Bartolucci et al. 2018); it was also recently reported also for Umbria (Bartolucci et al. 2019). A population of about 1 m² 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

Laburnum alpinum (Mill.) Bercht. & J.Presl (Fabaceae)

+ LAZ: Settefrati (Frosinone), Val Canneto tra Rifugio Acquanera e Casone Bartolomucci (WGS84: 41.713656N, 13.901975E ± 100 m), margine di faggeta, 1330 m, 4 September 2020, L. Cancellieri, G. Filibeck (UTV). – Species confirmed for the flora of Lazio.

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, 1949; Arrigoni 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).

Leucopoa spectabilis (Bertol.) H.Scholz & Foggi subsp. spectabilis (Poaceae)

+ TOS: Zeri (Massa-Carrara), tra Bergugliara e Patigno, lungo la SP 37 (WGS84: 44.34857N, 9.75561E), macereti lungo la strada, su serpentino, 655 m s.l.m. 28 August 2020, B. Foggi, A. Gabellini (FI). – Subspecies confirmed for the flora of Toscana.

The first record for Toscana can be found in Caruel (1866) in the Monte Pisano area, where the subspecies has never been found again (Del Prete et al. 1990; Pierini et al. 2009; Pierini and Peruzzi 2014). A large population was found in an area between Bergugliara and Patigno in a serpentine outcrop.

Phelipanche nana (Reut.) Soják (Orobanchaceae)

+ MAR: Cagli (Pesaro e Urbino) (WGS84: 43.541627N, 12.652022E), vegetazione di recupero di coltivi abbandonati 280 m, 16 May2020, leg. G. Mei, det. G. Mei, A. Stinca, G. Domina (FI, Herb. Mei). – Species new for the flora of Marche.

This species, whose range is restricted to the Mediterranean area (Domina et al. 2011), is an annual parasite of the root systems mainly of Urtica dioica L., Oxalis pes-caprae L., Asteraceae and Fabaceae, both spontaneous and cultivated (Domina 2018).

G. Mei, A. Stinca, G. Domina

Phlomis fruticosa L. (Lamiaceae)

+ SAR: Status change from doubtful alien to native for the flora of Sardegna.

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 (1827, 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.

Ganz). − Species new for the flora of Italy (Valle d’Aosta).

Pilosella paragogiformis was published as Hieracium paragogiforme by Käser (1903), who cited a handwritten description sent to him by Zahn. Our collection from 2013 was first identified as P. arida (Freyn) Soják, however the second collection from 2020 shows that the broad white margins of the phyllaries do not fit with this species.

Ranunculus rionii Lagger is a species distributed in Europe, North Africa, and central-western Asia (Wiegleb et al. 2017). In Italy, it is considered very rare (Pignatti et al. 2017), and is, so far, known with certainty only for Trentino-Alto Adige (Bartolucci et al. 2018), Lombardia, and Toscana (Bartolucci et al. 2019).

Salix repens L. subsp. repens (Salicaceae)

– ITALIA (LOM, VEN). Species to be excluded from the flora of Italy (Lombardia, Veneto).

Many old records of S. repens for Lombardia and Veneto are unreliable, lacking habitats suitable for this species. No herbarium specimens attest to its presence in these administrative regions. Furthermore, the recent report (Frattini 1997) for Lombardia (Piana del Gaver, Tonale) is not confirmed. Most records of S. repens are to be referred to Salix rosmarinifolia L. or S. helvetica Vill., so that the species is to be excluded from Italy.

In Toscana, Senecio doronicum subsp. doronicum has been reported by several authors along the northern Apennines (Raffaelli and Rizzotto 1991; Tomaselli et al. 2019; Marchetti 2020). According to Calvo et al. (2015), S. doronicum subsp. doronicum shows scattered arachnoid trichomes above the leaves and involucre weakly arachnoid to floccose. Our specimens, on the contrary, are glabrescent on both leaves and involucres, in agreement with the morphological features typical of S. doronicum subsp. orientalis. In Italy, S. doronicum subsp. orientalis occurs in many regions of the peninsula and on the eastern Alps (Bartolucci et al. 2018). In some localities, S. doronicum subsp. orientalis overlaps with S. doronicum subsp. doronicum, e.g., as in Monte Baldo (Veneto, Italy) (Calvo et al. 2015).

Stellaria ruderalis M.Lepší, P.Lepší, Z.Kaplan & P.Koutecký (Caryophyllaceae)

+ LOM: Milano (Milano), Monte Stella (WGS84: 45.490153N, 9.134815E ± 300 m), margine erboso, 130–180 m, 6 May 2020, leg. M. Martignoni, det. G. Galasso (FI, MSNM Nos 50831, 50832, 50833). – Species new for the flora of Lombardia.

This recently described species has been already reported for Italy (Lepší et al. 2019). The presence in Italy of this species is presumably much greater than currently documented, given its high morphological similarity with Stellaria media (L.) Vill.

Ulmus laevis Pall. (Ulmaceae)

+ C CAL: Corigliano-Rossano (Cosenza), Foce del Fiume Crati (WGS84: 39.717472N, 16.524165E), bosco planiziale igrofilo, 5 m, 22 August 2019, A. Brusco, R. Marchianò, G. Piovesan (FI). – Cryptogenic species new for the flora of Calabria.

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.
