In this contribution, new data concerning the distribution of native vascular flora in Italy are presented. It includes new records, confirmations, and exclusions to the Italian administrative regions. 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).

Ajuga chamaepitys (L.) Schreb. subsp. chamaepitys (Lamiaceae)

+ CAL: Oriolo (Cosenza), nei pressi della Cappella di San Francesco (WGS84: 40.059187°N, 16.430091°E), boscaglia mesofila con dominanza di Quercus pubescens e margini, 625 m, 22 May 2021, F. Roma-Marzio 1414 (PI No. 054235). – Subspecies confirmed for the flora of Calabria.

This subspecies was recorded by Lorenzetti and Iamonico (2009) based on three old specimens collected in Castrovillari and Laino Borgo and kept in RO, but it was no longer found in Calabria before this report.

Blackstonia acuminata (W.D.J.Koch & Ziz) Domin subsp. acuminata (Gentianaceae)

+PIE: Salbertrand (Torino), Regione Illes Neuves (WGS84: 45.074691°N, 6.893679°E), depositi golenali umidi adiacenti alla sponda sinistra della Dora Riparia, 997 m, 27 September 2021, M. Lonati, D. Barberis, M. Pittarello (FI). – Species confirmed for the flora of Piemonte.

Although Blackstonia acuminata is listed as absent in Piemonte (Bartolucci et al. 2018), this species was historically reported in the early 1900s (as Chlora perfoliata L. var. serotina Koch) in the hills around Turin (Negri 1905). Besides the locality recorded here, this species occurs also in a second close locality, along the right bank of the Dora Riparia. Several individuals grow on humid river sediments, together with Typha minima Funk ex Hoppe and Epipactis palustris (L.) Crantz.

Echinaria capitata was reported by Tenore (1824–1829, 1831), Parlatore (1848), and Pignatti (1982) as generically occurring in Calabria. Besides these reports, only old records for the province of Reggio Calabria are available (Porta 1879; Gentile and Di Benedetto 1962). For these reasosns, it was indicated by Bartolucci et al. (2018) as doubtfully occurring in Calabria.

According to Tenore (1830, 1831, under the name Spiraea filipendula L.), this species occurred in Pollino area, and it was later recorded also by Longo (1905) for Piano Novacco (Saracena). Then, Pignatti (1982) and Pignatti et al. (2017) quoted this species generically for Pollino. More recently, Bartolucci et al. (2018) reported this species as not occurring in the region.

Gladiolus illyricus W.D.J.Koch (Iridaceae)

– TOS. – Species to be excluded from the flora of Toscana.

Gladiolus illyricus was reported as doubtfully occurring in Toscana (Bartolucci et al. 2018), based on the only record published by Di Gaeta and Garbari (2009). However, the specimen linked to this publication and preserved in PI (No. 058973) is actually Gladiolus italicus Mill.

Gratiola officinalis L. (Plantaginaceae)

− CAM. − Species to be excluded from the flora of Campania.

Tenore (1824–1829) reported this species for “Terra di Lavoro”, for two localities actually placed in Lazio: Fondi [province of Latina] and San Germano [= Piedimonte San Germano, province of Frosinone] (NAP-Collection Tenore!). The same localities were listed by Caruel (1884), but later they were altogether reported as “T. di Lavoro” (Fiori and Béguinot 1900–1902), or, even more vaguely, as “Camp.” (Fiori 1926), and “Pal. Pontine, Camp.” (Pignatti 1982). No further specimen or literature data has been traced for Campania.

Littorella uniflora (L.) Asch. (Plantaginaceae)

EX VEN. – Extinct species for the flora of Veneto.

This species once occurred in the wetlands along Lake Garda (Pollini1822–1824; Goiran 1897–1904, as Littorella lacustris L.) as well documented also by several herbarium specimens in VER (AMG423b, AMG423c, AM394, AG2525b, AG2525c, CT327). It was then indicated as doubtfully occurring in the region (Conti et al. 2005; Bartolucci et al. 2018). The confirmation of the abovementioned herbarium specimens, together with the recent floristic researches conducted in the area, suggest that this species should be considered regionally extinct in Veneto (Buffa et al. 2016).

We found an isolated plant in Jelsi (Campobasso), quite distant from the rural construction Masseria della Vedova, and therefore we can exclude that it was cultivated for ornamental purposes. The cultivation of Q. suber in Molise for the production of acorns is also unlikely. The hypothesis that Q. suber is native in Molise is supported by the numerous (unpublished) reports of Q. × crenata Lam. that testify, for this region, a greater demographic incidence of Q. suber in the past.

Ranunculus polyanthemophyllus W.Koch & H.E.Hess (Ranunculaceae)

Rosa gallica L. (Rosaceae)

+ CAL: Oriolo (Cosenza), C.da Careto, bosco con prevalenza di roverella e carpino nero (WGS84: 40.059084°N, 16.406448°E), 685 m, 28 May 2021, F. Roma-Marzio 1415 (PI No. 054234). – Species confirmed for the flora of Calabria.

Rosa gallica was recorded in the past for the Pollino area (Petagna et al. 1827; Tenore 1830) and for Reggio Calabria at Capo Spartivento (Macchiati 1884). Both these localities were also reported by Caruel (1884), while Fiori (1924) indicated this species only for Pollino. More recently, Pignatti (1982) reported it generically for Calabria while Pignatti et al. (2017) state that it is missing in the region. Based on these data, Bartolucci et al. (2018) reported this species as historically occurring in Calabria.

Rosa montana Chaix (Rosaceae)

Rosa montana was reported as occurring in Toscana by Conti et al. (2005). However, Roma-Marzio et al. (2016) did not find bibliographic references or herbarium vouchers referring to this species, which was therefore considered as reported by mistake for the region.

Sambucus racemosa L. (Fabaceae)

– LAZ. – Species to be excluded from the flora of Lazio.

This species was considered as doubtfully occurring in Lazio by Anzalone et al. (2010), who cited Valle di Canneto (Picinisco) as the only location in the region, based on an old record by Tenore (1835: “Sorgente della Melfa”, a site erroneously referred to Abruzzo by Pignatti et al. 2018) and Tenore and Gussone (1842). However, there isn’t any specimen from this area labelled as S. racemosa in either Tenore or Gussone collections in NAP. Moreover, despite our field searches, we never found this species at the site where, instead, S. nigra L. is very common. The latter is not mentioned in the detailed floristic list of Valle di Canneto by Tenore and Gussone (1842): it was probably misnamed as S. racemosa.

Ulex europaeus L. subsp. europaeus (Fabaceae)

0 UMB: Bosco del giardino dei Murelli presso Perugia, 11 May 1906, G. Cicioni (PERU barcode PERU-00721811). – Species not recently confirmed for the flora of Umbria.

Ulex europaeus subsp. europaeus was recorded by Bartolucci et al. (2018) as doubtfully occurring for Umbria, although its presence was already reported for Monte Malbe near Perugia by Batelli (1887) and Barsali (1932) based on samples collected by Giulio Cicioni. The analysis of the herbarium Cicioni in PERU (Mazzerioli et al. 1996) allowed us to trace the aforementioned exsiccatum and to confirm the historical presence of this taxon in Umbria.

Vinca difformis Pourr. subsp. difformis (Apocynaceae)

Roma-Marzio 1797 (PI No. 054084). – Species new for the flora of Calabria.

Vinca difformis subsp. difformis is a west Mediterranean taxon that reach its eastern distribution limit in Italy (Marhold 2011+), where it is reported as rare in several regions from Liguria to Puglia (Bartolucci et al. 2018; Pignatti et al. 2018). Actually, this species was also reported in the past for the southern part of Calabria (Bisogni 1896, under the name Vinca media Hoffmanns. & Link). We found two different localities, distant from each other about 3 km, and about 3 km southeast from Basilicata, from which this species was recently excluded (Bartolucci et al. 2019a).
