Floristic records of native taxa

Acanthus spinosus L. (Acanthaceae)

+ CAL: Cirò (Crotone), loc. Favare, 550 m a sud della centrale (WGS84: 39.37787N, 17.04018E), boscaglia mediterranea, argilloso, 280 m, 13 October 2019, G. De Fine (CLU). – Species new for the flora of Calabria.

N.G. Passalacqua, G. De Fine

Alchemilla exigua L. (Rosaceae)

+ LAZ: Settefrati (Frosinone), Santuario di Canneto (WGS84: 41.713970N, 13.902108E), pascolo in loc. Casale Bartolomucci, suolo calcareo, 1327 m, 22 July 2020, G. Tondi, F. Minutillo (FI, Herb. Tondi). – Species confirmed for the flora of Lazio.

This population represents the first record outside of Monti della Laga in the central Apennines (Di Pietro et al. 2015; Ballelli and Allegrezza 2016).

F. Minutillo, G. Tondi

Alchemilla fissa Günther & Schummel (Rosaceae)

+ LAZ: Accumoli (Rieti), Agro Nero (WGS84: 42.701884N, 13.323876E), sponde rocciose di ruscello, in radura nella faggeta di Pannicaro, presso Lago Secco, suolo marnoso-arenaceo, 1590 m, 30 May 1999, G. Tondi (FI). – Species new for the flora of Lazio.

F. Minutillo, G. Tondi

Alchemilla subglobosa C.G.Westerl. (Rosaceae)

+ MAR: Monte Cavallo (Macerata), Monte Cetrognola (Riserva Statale Montagna di Torricchio) (WGS84: 42.96099269N, 13.00418242E), sotto nuclei di faggio e pascoli pingui adiacenti, substrato calcareo, 1350 m, 4 June 1987, S. Ballelli (FI; Herb. Ballelli; Herb. Tondi). – Species new for the flora of Marche.

This species shows its centre of distribution in northern and central Europe up to the Alps (Kurrto 2009). In Italy it is very rare and known only for few sites of the south Tyrolean and Trentino Alps (Pignatti et al. 2018; F. Festi pers. comm.).

S. Ballelli, G. Tondi

Anemone apennina L. (Ranunculaceae)

PIE. – Species to be excluded from the flora of Piemonte.

This species was first reported for Piemonte by Bellone et al. (2014) in two different localities in the Ligurian Alps: Limone Piemonte (Cuneo) and Frabosa Sottana (Cuneo). Recently, Bellone (2020) attributed the record from Limone Piemonte to Anemone blanda Schott & Kotschy, an allochthonous taxon originating from the Balkan peninsula, used for ornamental purposes. The specimen from Frabosa Sottana in TO must also be referred (revision by A. Selvaggi, 31 March 2021) to A. blanda, in accord with the keys proposed by Ziman et al. (2011) and Verloove (2017).

Apium graveolens L. (Apiaceae)

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

Apium graveolens is a Mediterranean species, whose presence is well documented in Sardegna (e.g., Moris 1840–1843; Milia and Mossa 1977; De Martis et al. 1984; De Martis and Loi 1989). It is common in moist places, swamps and riverbanks (Arrigoni 2013). Different horticultural varieties of this species are also widely cultivated as a vegetable . We speculate that the evaluation of its status as a casual alien may be derived from the interpretation of rarely occurring sub-spontaneous plants (Bacchetta 2006; Bacchetta et al. 2009). At any rate, its status is to be re-evaluated as a native to Sardegna.

Aristolochia pallida Willd. (Aristolochiaceae)

+ PUG: Gravina in Puglia (Bari), “Bosco Difesa Grande”, nei pressi di Lago Splendore in bosco a Quercus cerris e Q. frainetto (WGS84: 40.765021N, 16.381718E), 462 m s.l.m., 25 April 2018, campione coltivato in Orto Botanico sino a 28 May 2021, leg. G. Pazienza, L. Forte, det. G. Pazienza, L. Forte, V. Cavallaro (FI; BI Nos 42445, 42448, 42449, 42450, 42451, 42452). – Species new for the flora of Puglia.

Aristolochia pallida is considered as erroneously recorded in Puglia by Bartolucci et al. (2018), where it was formerly reported by Pasquale and Licopoli (1873) for the Gargano promontory at Sannicandro and by Palanza (1900)Nell’erboso sassoso del Pulicchio alle Murge di Gravina”. The ecological conditions of this locality are similar to those reported for this species in Basilicata (Forte 2001; Pignatti et al. 2017).

Bromus chrysopogon Viv. (Poaceae)

+ ITALIA (BAS): Maratea (Potenza), litorale presso il porto (WGS84: ca. 39.989508N, 15.705615E), incolto litoraneo, ca. 10 m, no exp., 19 April 1990, leg. E. Banfi, det. E. Banfi 15 February 2021 (FI, MSNM sub B. scoparius No. 24034). – Species new for the flora of Italy (Basilicata).

+ CAL: Praia a Mare (Cosenza), spiaggia in faccia all’Isola di Dino (WGS84: ca. 39.873902N, 15.783107E), dune, ca. 2 m, no exp., 20 April 1990, leg. E. Banfi, det. G. Osti & C. Acedo June 2018 (FI, MSNM sub B. scoparius Nos. 24031, 24032, 24033, 24035). – Species new for the flora of Calabria.

Bromus chrysopogon is a southeastern-Mediterraean species described from Libya, absent in Morocco, Spain, France and the former-Yugoslavia (Clayton et al. 2006+; Valdés and Scholz 2009+), possibly native to Italy. Initially confused with B. scoparius L. with which it shares a compact ovoid to flabellate synflorescence, it stands out (Sherif and Siddiqi 1988) for the spikelets 20–25 mm long (vs. 8–20 mm), the lemmas 9.0–11.5 × 3.0–4.0 mm (vs. 7.0–8.0(–10.0) × 1.0–2.5 mm), the awn up to 15 mm (vs. 9(–12) mm), and the brownish-golden, never anthocyanic panicle.

E. Banfi, G. Galasso

Bromus lepidus Holmb. (Poaceae)

+ C LOM: Magenta (Milano), Parco del Ticino, riserva “La Fagiana” (WGS84: 45.433122N, 8.829445E ± 400 m), margine di sentiero, ca. 100 m, no exp., 20 May 1993, leg. G. Galasso, det. G. Osti & C. Acedo June 2018 (MSNM sub B. hordeaceus No. 33852). – Cryptogenic species new for the flora of Lombardia.

Bromus lepidus is easy to identify for major lemmas shorter than 6.5 mm with a wide hyaline margin folded to an acute angle, and palea shorter than the caryopsis (Tison and de Foucault 2014). It had been reported for Italy (Piemonte and Lombardia) by Pignatti (1982), but without confirmation, and later excluded by the same author (Pignatti et al. 2017). It is impossible to evaluate if the species is native or alien to Lombardia, although in Trentino-Alto Adige it is considered a casual alien (Bartolucci et al. 2018).

Carex buekii Wimm. (Cyperaceae)

+ TOS: Firenze (Firenze), Fiume Arno (WGS84: 43.765973N, 11.286693E), riva destra del fiume vicino all’Hotel “Ville sull’Arno”, 10 May 2021, L. Lastrucci (FI). – New species for the flora of Toscana.

Carex buekii was reported as occurring only in Piemonte and doubtfully in Friuli Venezia Giulia (Bartolucci et al. 2018), where it has delimitation problems with the closely related C. randalpina B.Walln. (Koopman et al. 2018). This record represents the southernmost finding for Italy and the absolute southwestern limit for the range of this species (Koopman et al. 2018). In the collection site the species grows temporarily submerged.

Carex strigosa Huds. (Cyperaceae)

+ ABR: Rocca S. Maria (Teramo), F.so Valle Castellana (WGS84: 42.701884N, 13.323876E), schiarita umida in faggeta mista, loc. La Piana, sotto Colle Romicito; suolo marnoso-arenaceo, 1550 m, 15 September 2017, G. Tondi, F. Minutillo (FI, Herb. Tondi). – Species new for the flora of Abruzzo.

Catapodium pauciflorum (Merino) Brullo, Giusso, Miniss. & Spamp. (Poaceae)

+ LIG: Bergeggi (Savona), “IT1323202 Isola Bergeggi - Punta Predani” presso Punta del Maiolo (WGS84: 44.2374N, 8.442402E), macchia mediterranea, substrato calcareo, 16 m, 15 May 2020, D. Dagnino, L. Minuto (GE No. 2408); Portovenere (La Spezia), “IT1345005 Portovenere - Riomaggiore - San Benedetto” Castello di Portovenere, (WGS84: 44.050324N, 9.832397E), gariga a Euphorbia dendroides (Habitat Natura 2000 cod.5330), 21 m, 8 May 2020, D. Dagnino, C. Turcato (GE No. 5055); Portovenere (La Spezia), “IT1345005 Portovenere - Riomaggiore - San Benedetto” Castello di Portovenere, (WGS84: 44.048553N, 9.833048E), tasca sabbiosa sulla scogliera calcarea, 2 m, 8 May 2020, D. Dagnino, C. Turcato (GE No. 5075). – Species confirmed for the flora of Liguria.

Several old records of C. pauciflorum for Liguria are known from Brullo et al. (2003), Ottone Penzig’s handwritten notes found on a copy of De Notaris (1844) stored in the library of the University of Genova, and the GDOR herbarium (Barberis et al. 2019).

Cistus albidus L. (Cistaceae)

+ TOS: Monte Argentario (Grosseto), fra Punta Avoltore e Punta di Torre Ciana, (WGS84: 42.370900N, 11.167933E), nella gariga bassa a erica multiflora e rosmarino, su breccia calcarea, 88 m, 27 December 2019 (sterile), F. Selvi 4035 (FI); ibidem, 23 May 2020 (fruit), F. Selvi e I. Bettarini 4036 (FI); ibidem, 6 April 2021 (flower), F. Selvi e I. Bettarini 4044 (FI). – Species new for the flora of Toscana.

The native presence in Toscana was recently excluded (Bartolucci et al. 2016). In this new locality, C. albidus forms a very small population in a low garrigue with Erica multiflora L. and Salvia rosmarinus Spenn., on a warm, dry slope facing to the south, on rocky-gravelly calcareous soil. This is the typical habitat of this species. It is not known as a cultivated ornamental in the area, supporting its native status in this locality. Searches in the surrounding area, however, were not successful. The population is in urgent need of protection, as plants are close to a dirt road and subject to a high risk of being collected or extirpated.

Cladanthus mixtus (L.) Chevall. (Asteraceae)

+ LIG: Vado Ligure (Savona), sulla sponda destra del Quiliano (WGS84: 44.280714N, 8.444769E), 0 m, 07 April 2021, M. Callegari, B. Ciocia (GE) . – Species confirmed for the flora of Liguria.

Some historical herbarium specimens conserved in GDOR (Barberis et al. 2019) document the presence of the species in three localities: Voltri, Lagaccio, and Sarzana. Bibliographic data (Bertoloni 1853–1854; Ariello 1957) report the historical presence of this species in five other localities in the surroundings of La Spezia: Punta Mesco, Monterosso al Mare, Riomaggiore, Corniglia, and Canale Turì. The population consists of about ten individuals and some seedlings.

Convallaria majalis L. (Asparagaceae)

+ UMB: Costacciaro (Perugia), Monte Cucco, in Loc. Pignola (WGS84 43.366110N, 12.732120E), bosco misto su versante acclive con esposizione W, substrato carbonatico, c. 1050 m s.l.m., 30 May 2021, A. Di Filippo, A. Scoppola (UTV No. 38780). – Species confirmed for the flora of Umbria.

The species is reported as “doubtfully occurring” for Umbria (Bartolucci et al. 2018), although its presence was already reported for Monte Cucco in the sites Fosso di Musolea and Campo la Croce (Salerno and Puletti 1994, 1996), close to the site recorded here. This population is made up of clusters of a few dozen individuals, which 200–300 m upstream cover larger areas in the understory of a beech forest.

A. Di Filippo, A. Scoppola

Crucianella angustifolia L. (Rubiaceae)

+ VDA: Quart (Aosta), tra l’oratorio Beato Emerico, Duclos e Porsod (WGS84: 45.757630N, 7.406327E), praterie xerotermiche, 950–1180 m s.l.m., 7 June 2021, M. Lonati, A. Mainetti, S. Ravetto Enri (FI). – Species confirmed for the flora of Valle d’Aosta.

This species was recorded by Braun-Blanquet (1961) based on specimens in MPU collected in the localities of Veynes/Sorreley (Saint-Christophe) in 1956. It has not been recently recorded for Valle d’Aosta, where it is actually considered as cryptogenic (Bovio 2014; Bartolucci et al. 2018). Dozens of individuals were sparsely distributed over an area of about 10 hectares. Due to the species’ abundance and distribution across the semi-natural xero-thermic grasslands of Quart, we believe it most appropriate to consider this species as native.

M. Lonati, A. Mainetti, S. Ravetto Enri

Fedia graciliflora Fisch. & C.A.Mey. (Caprifoliaceae)

+ LAZ: Roma (Roma), Parco Petroselli (Talenti) (WGS84: 41.938009N, 12.557930E), pratello ai margini di un uliveto, lungo la rete di confine, suolo tufaceo, 37 m, 19 April 2019, G. Tondi, G. Pellegrino (FI, Herb. Tondi). – Species new for the flora of Lazio.

F. Minutillo, G. Tondi

Helianthemum salicifolium (L.) Mill. (Cistaceae)

+ LIG: Diano San Pietro (Imperia), “IT1315602 Pizzo di Evigno” M. Lago (WGS84: 43.96365N, 8.06141E), prateria arida su substrato calcareo (Habitat Natura 2000 cod.6210*), facies densamente arbustata, 625 m, 25 May 2020, D. Dagnino, M. Mariotti (GE No. 2989). – Species confirmed for the flora of Liguria.

Some old records (De Notaris 1844; Bertoloni 1842–1844) and herbarium specimens housed in GDOR (Barberis et al. 2019) document the presence of this species in localities in the province of Savona (Albenga, Ceriale) and near Genova. According to Ottone Penzig’s handwritten notes found on a copy of De Notaris (1844), stored in the library of the University of Genova, this species was also present at Capo Berta, an area close to the site of the current discovery.

Hieracium pilosum Schleich. ex Froel. subsp. villosifolium (Nägeli & Peter) Greuter (Asteraceae)

+ EMR: Corniglio (Parma), tra il Lago Santo e La Sella del Marmagna (WGS84: 44.395387N, 10.000874E), prateria subalpina, 1700 m, 25 July 2020, leg. L. Pinzani, det. G. Gottschlich (FI). – Subspecies new for the flora of Emilia-Romagna.

Juncus ranarius Songeon & E.P. Perrier (Juncaceae)

+ VEN: Sopra Ruaz - Livinallongo (Belluno) (WSG84 46.496466N, 11.919887E), margine strada statale, 1400 m s.l.m., 4 August 2008, S. e C. Argenti (FI barcode FI064007, Herb. Argenti No. 16801). – New species for the flora of Veneto.

The distribution of Juncus ranarius in Italy was recently updated (Lastrucci et al. 2022), highlighting a certain ecological amplitude for this species. This record confirms the ability of J. ranarius to originate populations even in non-halophilic habitats.

L. Lastrucci, C. Argenti

Lamium galeobdolon (L.) L. subsp. galeobdolon (Lamiaceae)

+ LAZ: Acquafondata (Frosinone) (WGS84: 41.514925N, 13.961504E), bosco di Ostrya carpinifolia, substrato calcareo, 990 m, 14 May 2016, F. Minutillo (FI, Herb.Minutillo, Herb. Tondi). – Subspecies new for the flora of Lazio.

F. Minutillo, G. Tondi

Lolium arundinaceum (Schreb.) Darbysh. subsp. corsicum (Hack.) J.-M.Tison (Poaceae)

+ SAR: Perdu Locci, Pula (Sud Sardegna), prati umidi (WGS84: 38.995073N, 9.012160E), 1 m, 18 June 2021, M. Fois, G. Bacchetta (FI, CAG); Sa Giaga, Tula (Sassari), sponde sabbiose lacustri (WGS84: 40.762810N, 9.010656E), 164–165 m s.l.m., 16 June 2013, G. Calvia (Herb. Calvia). – Subspecies new for the flora of Sardegna.

Lolium arundinaceum subsp. corsicum is a perennial herb endemic to Corsica and Toscana (Bartolucci et al. 2018). This subspecies was doubtfully recorded for Sardegna, based on the synonymy with Festuca arundinacea var. insularis Gennari proposed by Banfi et al. (2017). We confirm its presence in several sub-halophilous wet meadows near the coast and inland plains of southern Sardegna, as well as in sandy and wet places of northern Sardegna.

Pilosella fusca (Vill.) Arv.-Touv. (Asteraceae)

+ LOM: Sondalo (Sondrio), sentiero in Valle di Rezzalo, presso la chiesa di San Bernardo (WGS84: 46.35728N, 10.41861E), prateria alpina aperta di fondovalle, ca. 1850 m, 10 July 2005, leg. S. Perego, det. G. Gottschlich 2021 (MSNM No. 44104 sub Hieracium aurantiacum). – Species confirmed for the flora of Lombardia.

La Selva - Lago di Cardito (WGS84: 41.607930N, 13.989928E), boscaglia igrofila, suolo alluvionale a matrice calcarea, 1030 m, 22 June 2013, G. Tondi, F. Minutillo (FI, Herb. Tondi). – Species new for the flora of Lazio.

This species, previously overlooked, is quite common in wet habitats across a wide elevational range in SE-Lazio (Val Comino, Meta and Mainarde districts).
