Note: This endemic taxon was until now recorded only for Puglia region [
56]. It is noteworthy to underline the presence in Basilicata of two infraspecific taxa of
Alyssum diffusum: the subspecies
calabricum Španiel, Marhold, N. G. Passal. and Lihová in the Campano-Lucano Apennine, along the border with Campania and Calabria regions [
16] and the subsp.
garganicum in the easter part, along the border in Puglia region.
Anredera cordifolia (Ten.) Steenis [≡ Boussingaultia cordifolia Ten.]
Basellaceae Phanerophyte climbing Neophyte, S-America
First record for Basilicata (casual)
Specimen: 15-6-2014, Lido di Policoro (Policoro, Matera province), roadside, 40.17361° N-16.70099° E, 3 m a.s.l., leg. G. Salerno et M.R. Lapenna, det. G. Salerno (Herb. Salerno).
Note: Casual or naturalized alien species in most of the peninsular and insular regions except for Umbria [
17]. It is considered an invasive taxon in Toscana [
17].
Asclepias physocarpa (E. Mey.) Schltr. [≡ Gomphocarpus physocarpus E. Mey.]
Apocynaceae Phanerophyte caespitose Neophyte, S-Africa
First record for Calabria (casual)
Specimen: 1-7-2019, Campo Calabro (Reggio Calabria province), roadside, 38.20633° N-15.64897° E, leg. V.L.A. Laface, det. V.L.A. Laface et G. Spampinato (REGGIO).
Note: Five plants were recorded along the road, mixed with
Hyparrhenia hirta (L.) Stapf. subsp.
hirta and
Rubus ulmifolius Schott. It was previously recorded as casual or naturalized alien species only in Toscana, Campania, and Sicilia regions [
17].
Asplenium viride Huds.
Aspleniaceae Hemicryptophyte rosulate Circumboreal
First record for Sardegna
Specimen: 14-5-2013, Monte Albo (Siniscola, Nuoro province), 40.54141° N-9.62394° E, sinkhole shaft in montane karstfield, 880 m a.s.l., leg. et det. P.J. de Lange (AK, SS).
Note. Recorded from all regions of Italy except for Puglia and doubtfully for Basilicata, but until now absent in the insular regions (Sardegna and Sicilia) [
16]. However,
Asplenium viride had been reported from Sardegna from a locality close to Fluminimaggiore (Iglesiente, South-western Sardegna) from where it has not since been seen [
57]. Recently Ballero et al. [
57] suggested its exclusion from the flora of Sardegna.
Aubrieta columnae Guss. subsp. italica (Boiss.) Mattf. [≡ A. italica Boiss.]
Brassicaceae Chamaephyte subshrubs Italian endemic
First record for Lazio (naturalized)
Specimen: 5-8-2019, Old town (Anticoli Corrado, Roma province), old walls, 500 m a.s.l., 42.00991° N-12.99103° E, leg. et det. L. Rosati (HLUC).
Note: A small population of this Italian endemic taxon, which grows in nature only in Puglia (Gargano peninsula) and doubtfully in Basilicata, was observed for over 10 years in anthropogenic habitat at Anticoli Corrado (Rosati, pers. observ.). These individuals have spread by seeds from a nearby cultivated plant in pots and urban gardens. Our specimens were identified using the key by [
58].
Bellevalia boissieri Freyn [≡ Bellevalia dubia (Guss.) Kunth subsp. boissieri (Freyn) Feinbrun]
Asparagaceae Geophyte bulbouse E-Mediterranean
First record for Basilicata
Specimen: 28-3-2018, Iazzo di Tucci (Rotondella, Matera province), olive groves, 40.17157° N-16.53832° E, 298 m a.s.l., leg. G. Salerno et G. Misano, det. G. Salerno (Herb. Salerno).
Note: Until these discoveries this species was known from Italy only from the Calabria region [
16].
Bupleurum rollii (Montel.) Moraldo [≡ B. gracile d’Urv. var. rollii Montel.]
Apiaceae Therophyte scapose Italian endemic
First record for Campania
Specimen: 8-9-2013, Monte Vesole (Roccadaspide, Salerno province), chestnuts, 580 m a.s.l., 40.41156° N-15.16761° E, leg. et det. G. Salerno (Herb. Salerno).
Note. This Italian endemic had previously been recorded from Lazio to Sicilia, but not from Campania [
16].
Campanula poscharskyana Degen
Campanulaceae Hemicryptophyte scap Neophyte, SE-European (Dinarides)
First record for Lazio (casual)
Specimen: 5-8-2019, Old town (Roviano, Roma province), calcareous rock crevices, 495 m a.s.l., 42.02565° N-12.99403° E, leg. et det. L. Rosati (HLUC).
Note: This alien species was reported as casual or naturalized only in Lombardia, Veneto, and Toscana [
17].
Cenchrus longisetus M. C. Johnst. [= Pennisetum villosum R. Br. ex Fresen.]
Poaceae Hemicryptophyte caespitose Neophyte, Paleotropical
First record for Calabria (casual)
Specimen: 16-6-2019, San Roberto (Reggio Calabria province), sidewalks, 280 m a.s.l., 38.21074° N-15.736° E, leg. V.L.A. Laface, det. V.L.A. Laface, C.M. Musarella et G. Spampinato (REGGIO).
Note: Collected from the margins of sidewalks where it was probably derived from a nearby flowerbed. This species has been recorded from Italian regions as casual or naturalized [
17]; only in Sardegna is it considered invasive [
17].
Chamaerops humilis L.
Arecaceae Nano-phanerophyte Neophyte, W-Mediterranean
First record for Basilicata (casual)
Specimen: 14-12-2017, S. Basilio, Marina di Pisticci (Pisticci, Matera province), clearings in mediterranean maquis, 3 m a.s.l., 40.2998° N-16.78265° E, leg. et det. S. Fascetti (HLUC).
Note: Although this palm is indigenous to the neighboring regions of Campania and Calabria [
16], it has not been recorded in the previous flora of Basilicata [
51]. Therefore, as for the neighboring Puglia region [
16], we consider it as introduced to this region. Plants probably spread from cultivation as the species was present in the nearby gardens, and only juvenile plants and seedlings were observed.
Commelina erecta L.
Commelinaceae Terophyte crawling Archeophyte, C-America
First records for Calabria and peninsular Italy (casual)
Specimens: 23-6-2019, Lazzaro (Motta San Giovanni, Reggio Calabria province), crevices between road and sidewalks, 16 m a.s.l., 37.97394° N-15.66507° E, leg. et det. C. M. Musarella (REGGIO); 25-6-2019, Catona (Reggio Calabria, Reggio Calabria province), sidewalks, 22 m a.s.l., 38.17987° N-15.64811° E, leg. V.L.A. Laface, det. V.L.A. Laface, C.M. Musarella et G. Spampinato (REGGIO).
Note: Observed growing in crevices and on the edge of the roadside. Probably escaped from plants cultivated in pots placed on sidewalks. It was recently reported for the first time in Italy in Sicilia by [
38].
Conringia orientalis (L.) Andrz. ex DC. [≡ Brassica orientalis L.; ≡ Gorinkia orientalis (L.) J. Presl and C. Presl]
Brassicaceae Therophyte scapose Neophyte, W-Asia
First record for Campania (casual)
Specimen: 15-5-2018, Campitello, Monti della Maddalena (Padula, Salerno province), forest edges, along a track, 1270 m a.s.l., 40.3452° N-15.68886° E, leg. S. Fascetti, det S. Fascetti et L. Rosati (HLUC).
Note: It is considered an archaeophyte associated with cereal crops, as stated for example in a previous record for Basilicata [
59]. However, our finding of
C. orientalis was in a silvo-pastoral habitat, quite far from cultivated areas.
Convolvulus siculus L. subsp. siculus
Convolvulaceae Therophyte scapose S-Mediterranean
First record for Basilicata
Specimen: 12-3-2012, Torre Caina (Maratea, Potenza province), clearings in mediterranean maquis, 39.94319° N-15.73534° E, 880 m a.s.l., leg. et det. G. Salerno (Herb. Salerno).
Note: It was previously recorded in Liguria, Toscana, Lazio, Campania, Puglia, Sicilia, and Sardegna regions [
16].
Coprosma repens A. Rich.
Rubiaceae Nano-phanerophyte Neophyte, New Zealand
First record in Italy (casual)
Specimen: 10-03-2013, Torre Nuova, Porto Conte (Alghero, Sassari Province), occasional shrubs growing by old Spanish tower near beach, 2 m a.s.l., 40.593647° N-8.20430° E, leg. et det. P.J. de Lange (AK).
Note: Growing among
Myoporum laetum G. Forst.,
M. aff. insulare R. Br.,
M. laetum ×
M. aff. insulare. Plants with flower buds, seedlings present. In Europe, although it has been recorded only from Great Britain [
60], this species was commonly seen by PdL along the coastline of southern France (1999, 2013), and northern Spain (Catalonia) (2013). It seems surprising it has not naturalized further as under the vernacular “mirror bush” it is recorded as an aggressive invasive species throughout much of the world [
61].
Cordyline australis (G. Forst.) Endl. [≡ Dracaena australis G. Forst.]
Asparagaceae Phanerophyte scapose Neophyte, New Zealand
First record for Sardegna (casual)
Specimen: 12-3-2012, Via Tarragona (Alghero, Sassari province), courtyard garden 30 m a.s.l., 40.55422° N-8.32475° E, leg. et det. P.J. de Lange (AK, SS).
Note: Seedling collected from rank grassland within inner courtyard garden. Growing close to planted adult fruiting trees. Although this species is a very commonly cultivated tree in Sardegna, so far, only sparingly naturalizing. This may be because mostly only one clone is grown, and the species is self-incompatible [
62]. Outside Sardegna this species has been reported as a casual alien only in Marche, Abruzzo, and Campania [
17].
Cyclamen balearicum Willk. [≡ C. repandum Sm. subsp. balearicum (Willk.) O. Schwarz]
Primulaceae Geophyte bulbouse NW-Mediterranean
First record for Italy (Sardegna)
Specimen: 20-4-2008, Monte Doglia (Alghero, Sassari province), evergreen woodlands of Prasio majoris-Quercetum ilicis chamaeropetosum humilis, 40.60742° N-8.24683° E, 190 m a.s.l., leg. et det. E. Farris (SS).
Note: Cyclamen balearicum differs from
C. repandum in having leaves usually adaxially speckled with white and flowers that are either fully white or with a white-veined pale pink corolla [
42]. Recent research [
63,
64] highlighted the presence of a hybrid zone between
Cyclamen repandum and
C. balearicum in NW Sardegna, where hybrid plants displaying bi-colored flowers prevail, and pure
C. balearicum plants were scarce. However, based on the original observations, at Mt. Doglia plants with small white flowers and non-exerted stigma are dominant, though only occasional individuals have the diagnostic leaf ornamentation of
C. balearicum s.s. The nearest known localities of this species according to Flora Gallica and Flora Iberica are in Corsica (France), Provence (S-France), and Balearic Islands (Spain).
Daucus aureus Desf.
Apiaceae Therophyte scapose S-Mediterranean
First record for Basilicata
Specimen: 1-5-2019, Serra delle Grotte (Rotondella, Matera province), fallows on clay soils, 120 m a.s.l., 40.19691° N-16.49405° E, leg. G. Salerno et G. Misano, det. G. Salerno (Herb. Salerno).
Note: At present known only from Calabria and Sicilia [
16]. There are historical doubtful records of this species from Liguria and Campania, respectively [
16].
Dichoropetalum carvifolium-chabraei (Crantz) Soldano, Galasso and Banfi [≡ Selinum carvifolium-chabraei Crantz; – Holandrea carvifolia Reduron, Charpin and Pimenov; = Peucedanum carvifolium-chabraei (Crantz) Soldano]
Apiaceae Hemicryptophyte scapose European-Caucasian
First record for Lazio
Specimen: 16-7-2015, Monte Tilia, Fondo del Laghetto (Leonessa, Rieti province), secondary grassland with Brachypodium genuense, marly-calcareous slopes, 1400 m a.s.l., 42.55842° N-12.95441° E, leg. et det. E. Del Vico (Herb. Del Vico).
Note: In Italy it is reported in many northern and central regions and in Sicilia [
16].
Epilobium nummularifolium R. Cunn. ex A. Cunn.
Onagraceae Hemicryptophyte crawling Neophyte, New Zealand
First record for Italy (casual)
Specimen: 24-04 2013, via Castelsardo (Alghero, Sassari province), damp ground on side of road adjacent pasture used for hay making, 6 m a.s.l., 40.57221° N-8.32010° E, leg. et det. P.J. de Lange (AK, SS).
Epilobium nummularifolium is apparently not known wild elsewhere in greater Europe [
65]. However, this species has a superficial similarity to
E. brunnescens (Cockayne) Raven et Engelhorn subsp.
brunnescens, which is abundantly naturalized in the British Isles, and reported from the Guernesy Islands, so it is possible that it has been confused with that species, and so overlooked [
65].
E. nummularifolium, a New Zealand endemic, is well-known for its aggressive, weedy nature. Raven and Raven [
65] argue that this species was once a narrow range endemic of northern New Zealand, which has spread throughout that archipelago as a garden plant pot contaminant. We suspect that this is how it has reached Sardegna, i.e., as a possible soil/garden plant contaminant, introduced alongside anyone of the many New Zealand indigenous/endemic plants seen there in cultivation. This species should be looked for elsewhere in Europe.
Epilobium nummularifolium is distinguished from both
E. brunnescens and
E. komarovianum H. Lev, which is also naturalized in Europe [
65] by the yellow-green, serrulate leaves, purple-blue stems, and grey-strigulose capsules [
65,
66,
67,
68] (
Table A1,
Figure A1). These species are keyed out as follows:
- 1.
Adaxial leaf surface deeply rugose-impressed E. komarovianum
- 1.
Adaxial leaf surface smooth, not rugose-impressed 2
- 2.
Leaves yellow-green, with red margins, serrulate bearing 2-11 pairs of teeth either side of midrib; stems purple-blue, capsules grey-strigulose E. nummularifolium
- 2.
Leaves dark green, tinged red or brown, entire or with 1-4 pairs of indistinct teeth either side of midrib, capsules glabrate, rarely very sparsely hairy E. brunnescens

Note: Euphorbia nutans was recorded as casual or naturalized alien in most of the Italian regions [
17]. It is considered invasive in Lombardia and Veneto [
17].
Euphorbia stricta L. [= Euphorbia serrulata Thuill.]
Euphorbiaceae Therophyte scapose European-Caucasian
First record for Basilicata and confirmation for peninsular Italy
Specimen: 12-6-2018, Vascarano, Pergola (Marsico Nuovo, Potenza province), traditional arable land, 915 m a.s.l., 40.42385° N-15.68713° E, leg. et det. L. Rosati (HLUC).
Note: Previously, and reliably reported only from the northern Italian regions [
16]; this record provides the first verified evidence of its presence in peninsular Italy. Previously it was considered as doubtfully present in Lazio [
16], while it has not been recently recorded from Abruzzo and Calabria [
16], and was apparently recorded by mistake from Sicilia [
16].
Fagopyrum esculentum Moench
Polygonaceae Therophyte scapose Neophyte, Asia
First record for Basilicata (casual) and confirmation for Calabria (casual)
Specimens: 7-9-2011, Diga Masseria Nicodemo, Lago di Cogliandrino (Lauria, Potenza province), fallows, mesic grasslands, 670 m a.s.l., 40.08151° N-15.93680° E, leg. et det. S.

Hieracium pallescens Waldst. and Kit. s.l.
Asteraceae Hemicryptophyte scapose SE-European
First record for Lazio
Specimen: 29-7-2015, Rifugio Sebastiani, Monte Terminillo (Rieti province), pastured grassland dominated by Bromopsis erecta with Helictochloa praetutiana, Brachypodium genuense, Carex kitaibeliana, and Festuca violacea subsp. italica, limestone, 1870 m a.s.l., 13.01343° N-42.46902° E, leg. E. Del Vico et L. Facioni, det. G. Gottsclich (Herb. Del Vico).
Note: This species is present in all the northern regions of Italy except for Liguria [
16]. In peninsular Italy it was recorded only from Abruzzo, Campania, Basilicata, and Calabria [
16]. About twenty subspecies of
H. pallescens are present in Italy; however, our specimen does not allow to ascertained the subspecific level. Further on filed investigations should be performed to fix this gap.
Himantoglossum hircinum (L.) Spreng. [≡ Satyrium hircinum L.]
Orchidaceae Geophyte bulbouse Mediterranean-Atlantic
First record for Sardegna
Specimen: 22-5-2013, Illorai forest (Illorai, Sassari province), within a small clearing in otherwise dense Quercus ilex and Q. pubescens forest, 40.40494° N-8.92588° E, photo et det. P. J. de Lange.
Note: This species is present in Italy in the north-western (Piemonte, Liguria, Toscana and Emilia-Romagna) and in the southern regions with a clear gap in central Italy [
16]. Although it is a very showy orchid it was never seen before in Sardegna, probably because of its rarity.

Specimen: 31-7-2015, Fossa Cupa (Sasso di Castalda, Potenza province), Fagus sylvatica forest, 40.50972° N-15.73002° E, leg. V.A. Romano, det. L. Rosati (HLUC).
Note: This species was reported first from Basilicata by Bartolucci et al. [
16] based on our unpublished record above. Here we provide full details of the discovery.
Isoëtes durieui Bory
Isoëtaceae Geophyte bulbouse W-Steno-Mediterranean
First record for Basilicata
Specimen: 2-5-2019, Bosco Finocchio (Rotondella, Matera province), ponds within Quercus cerris forest, 600 m a.s.l., 40.15282° N-16.47588° E, leg. G. Salerno et G. Misano, det. G. Salerno (Herb. Salerno).
Note: It was previously recorded for all western Italian regions though considered doubtfully in Molise [
16].
Isopyrum thalictroides L.
Ranunculaceae Geophyte rhizomatous Eurasian
First record for Sardegna
Specimen: 15-6-2014, Fontana Is Bidileddos (Desulo, Nuoro province), riparian forest of Glechomo sardoae-Alnetum glutinosae, 1660 m a.s.l., 40.01029° N-9.309394° E, leg. et det. E. Farris (SS).
Note: Locally common on the Fonni mountain side, exclusively in
Alnus glutinosa forests above 1500 m a.s.l. (see
https://inaturalist.nz/observations/4112222). This taxon is present throughout Italy, in most of the central-northern regions of Italy and though absent south of Toscana [
16]. Our finding is the first for Mediterranean islands. This is noteworthy as it is believed to be absent from Corsica [
72].
Kalanchoë × houghtonii D. B. Ward [≡ Bryophyllum × houghtonii (D. B. Ward) P. I. Forst.; Kalanchoë daigremontiana Raym. -Hamet and H. Perrier × Kalanchoë delagoensis Eckl. and Zeyh.]
Crassulaceae Ch succulent Neophyte, horticultural origin
First record for Basilicata (naturalized)
Specimen: 3-8-2017, Porto (Maratea, Potenza province), calcareous sea cliffs, 6 m a.s.l., 39.98835° N-15.70995° E, leg. A. Stinca et M. Eviano. det. A. Stinca (PORUN-Herb. Stinca).
Note: At Maratea
Kalanchoë ×
houghtonii seems to form populations capable of self-sustaining reproduction. Indeed, because of the viviparous nature, whereby the leaf lamina produces myriad plantlets this species has the potential to be highly invasive. It is recorded as naturalized from Liguria, Toscana, Lazio, and Calabria; it is present as casual in Campania, Puglia, Sardegna, and Sicilia [
17].
Kickxia spuria (L.) Dumort. subsp. spuria [≡ Antirrhinum spurium L. subsp. spurium]
Plantaginaceae Therophyte scapose Eurasian
First record for Campania
Specimen: 29-7-2014, near Vallone Serra Melito (Capaccio Paestum, Salerno province), arable land, 40.41596° N-15.08801° E, leg. et det. A. Stinca (PORUN-Herb. Stinca).
Note: This is the first record for the Southern Italian peninsula [
16].
Lantana montevidensis (Spreng.) Briq. [≡ Lippia montevidensis Spreng.]
Verbenaceae Nano-phanerophyte Neophyte, S-America
First record for Sardegna (casual)
Specimen: 30-8-2018, Su Giudeu (Domus de Maria, Cagliari province), crevices in the walls, 5 m a.s.l., 38.88749° N-8.85886° E, leg. et det. L. Rosati et M. Marignani (HLUC).
Note: Previously reported as a casual alien only from Liguria and Calabria regions [
17]. In Sardegna this species is widely grown in urban green areas, pots, and Mediterranean gardens (pers. observ.) so further naturalizations are likely.
Lathyrus cirrhosus Ser.
Fabaceae Hemicryptophyte NW-Steno-Mediterranean
Exclusion for Italy (Sardegna)
Note: This taxon was reported only once at Monte Arviganu and Monte S. Giuliano, near Alghero, Sardegna by Schmid [
49]. Pignatti [
19,
47] and Arrigoni [
73] stated that the presence of
L. cirrhosus in Sardegna is doubtful because of the probable confusion with
L. heterophyllus L. Nevertheless, it was considered present in Sardegna in the Italian Flora checklists of vascular plants [
16,
74]. We have unsuccessfully searched for this species in the two sites during the last decade, and in the absence of verified herbarium evidence of its historic presence we recommend that
L. cirrhosus be excluded from the flora of Sardegna and Italy.
Lathyrus inconspicuus L.
Fabaceae Therophyte scapose Euri-Mediterranean
First records for Lazio
Specimens: 11-6-2015, Monte Porillo (Micigliano, Rieti province), secondary grassland with Bromopsis erecta and Brachypodium rupestre, gently marly slopes, 1000 m a.s.l., 42.45552° N-13.06439° E, leg.

Del Vico).
Note: In peninsular Italy
L. incospicuus was previously recorded from Toscana, Marche, Abruzzo, and Puglia; indeed, in Umbria and Campania its presence is doubtful [
16]. It is absent in the southern and insular regions [
16].
Linum tenuifolium L.
Linaceae Chamaephyte subshrubs Steno-Mediterranean-Euxinian
Exclusion for Sardegna
Note: The presence of this taxon in Sardegna was reported by Mossa et al. [
50] and so accepted in the Italian checklist of vascular flora [
16,
74]. Nevertheless, the species is excluded by [
75] who considers its presence a mistake, because of the confusion with
L. bienne. Our surveys in the site from where
Linum tenuifolium was reported by Mossa et al. [
50] found only
L. bienne. Therefore,
L. tenuifolium has to be excluded from Sardegna. It was also reported by mistake in Sicilia region [
16].
Lonicera japonica Thunb.
Caprifoliaceae Phanerophyte climbing Neophyte, E-Asia
First record for Basilicata (casual)
Specimen: 14-6-2019, Macchia Romana, Campus of University of Basilicata (Potenza), crevices in road pavements close to the walls, 40.68829° N-15.80848° E, 735 m a.s.l, leg. et det. L. Rosati (HLUC).
Note:Lonicera japonica has been recorded from all Italian regions except for Molise and Basilicata [
17]. It is considered invasive in several regions of Northern Italy [
17].

Metrosideros excelsa Sol. ex Gaertn. [= M. tomentosa A. Rich.; = Nania tomentosa (A. Rich.) Kuntze]
Myrtaceae Phanerophyte caespitose Neophyte, New Zealand
First record for Europe (Azores and Madeira excluded) (casual)
Specimen: 31-5-2013, Costa Rei, Monte Nai (Muravera, Cagliari province), urban areas, 20 m a.s.l., 39.2565° N-9.575611° E, leg. et det. P.J. de Lange (AK, SS).
Note: A few seedlings, and saplings growing in the vicinity of the planted adult trees; this species is common in many coastal towns and resorts around Sardegna (see for example
https://inaturalist.nz/observations/1715168).
Metrosideros excelsa, commonly known as “New Zealand Christmas tree,” is a coastal evergreen tree that produces a brilliant display of red flowers. It has been recently added to the list of host plants referred to in Article 1(b) of Commission Implementing Decision (EU) 2015 2417 of 17 December 2015, which have been found to be susceptible to
Xylella fastidiosa in the European Union territory.
Until this record
Metrosideros excelsa had been recorded in Europe as a naturalized plant only from the Azores and Madeira (Portugal) by [
76]. Thus, our finding represents the first record for Europe (Azores and Madeira excluded).

Solanaceae Therophyte scapose Neophyte, S-American
First record for Calabria (casual)
Specimen: 3-6-2019, S. Litterata (Belvedere Marittimo, Cosenza province), fallows, 35 m a.s.l., 39.65594° N-15.83856° E, leg. et det. A. Capano (HLUC).
Note: This species was recorded in Italy from several regions; it is present in almost all of the central and northern regions as a casual alien; in Piemonte, Trentino-Alto Adige, and Friuli-Venezia Giulia it is considered naturalized [
17]. It is absent in most of the southern regions, except for Sicilia [
17].

Note: Previously it was only recorded from Calabria, Sicilia, and Sardegna; no recent records are found from Puglia [
16]. The presence of this taxon in Basilicata (Matera and Potenza Province) was also reported in the Forum Acta Plantarum (“
Nigella arvensis subsp.
glaucescens (Guss.) Greuter and Burdet—Scheda IPFI, Acta Plantarum.” Available on line (access date: 02-10-2019):
http:\\www.actaplantarum.org\flora\flora_info.php?id=5297).

Note: Probably escaped from cultivated plants growing in pots placed on the sidewalks from where it had spread into crevices and the edge of the roadside. It was recorded as naturalized in Toscana, Campania, and Puglia [
17] and as casual alien in Piemonte, Liguria, and Sardegna [
17].
Oeosporangium tinaei (Tod.) Fraser-Jenk. [≡ Cheilanthes tinaei Tod.; = C. corsica Reichst. and Vida]
Pteridaceae Hemicryptophyte rosulate Steno-Mediterranean-Macaronesian
First record for Lazio

16].
Oloptum miliaceum (L.) Röser and H. R. Hamasha [≡ Agrostis miliaceum L.; ≡ Oryzopsis miliacea (L.) Asch. and Schweinf.; ≡ Piptatherum miliaceum (L.) Coss.]
Poaceae Hemicryptophyte caespitose Mediterranean-Turanian
First records for Sardegna
Specimens: 2-6-2018, Sirigragiu, Corongiu (Maracalagonis, Cagliari province), reforestation with Eucaliptus, 84 m a.s.l., 9.2791° E-39.28434° N, leg. et det. E. Lallai (Herb. E. Lallai); 7-6-2018, C.

Note: In the recent checklist of Italian vascular flora only
O. thomasii and not
O. miliaceum has been reported from Sardegna [
16]. However,
O. miliaceum is the only species that has ever been considered present in the flora treatments of Sardegna e.g., [
47,
74,
75]. In addition, several authors consider questionable the distinction between these two taxa and include
O. thomasii in
O. milaceum. Our observations confirm the presence of
O. miliaceum, accordingly this name has to be re-added to the checklist of vascular flora of Sardegna.
O. miliaceum is present in almost all Italian regions except Valle d’Aosta, Piemonte e Molise [
16].
Ophrys crabronifera Mauri [≡ O. argolica H. Fleischm. ex Vierh. subsp. crabronifera (Mauri) Faurh.; = O. exaltata Ten. subsp. sundermannii Soó; = O. fuciflora (F. W. Schmidt) Moench subsp. sundermannii Soó]

Note: Abundantly naturalized. In some stations of Calabria, it probably escaped from plants grown in pots cultivated on the sidewalks as plants were seen in nearby crevices and on the nearby roadside. It was previously reported for almost all the Italian regions except for Molise, Basilicata, and Calabria in southern Italy [
17]. In Basilicata region it is reported in the forum Acta Plantarum (2007 on—"

Musarella (REGGIO); 9-8-2019, C. da Sant’Angelo (Melia di San Roberto, Reggio Calabria province), road escarpment, 749 m a.s.l., 38.22281° N-15.77548° E, leg. V.L.A. Laface, det. V.L.A. Laface et G. Spampinato (REGGIO); 19.10.2019, Fiumara di S. Lorenzo (S. Lorenzo, Reggio Calabria province), bedriver, 6 m a.s.l., 37.920494° N-15.839534° E, leg. et det. V.L.A. Laface (REGGIO).
Note: In southern Italy it was previously recorded only for Campania (naturalized) and Sicilia (casual) [
17].
Physalis peruviana L.
Solanaceae Hemicryptophyte scapose Neophyte, S-America
First record for Calabria (casual)
Specimen: 23-8-2019, Thurio (Corigliano Calabro, Cosenza province), fallows, 8 m a.s.l., 39.69515° N-16.46777, leg. P. Nicoletti, det. L. Rosati (HLUC).
Note: In southern Italy recorded previously only from Puglia and Sicilia regions [
17].
Pinus nigra J. F. Arnold subsp. laricio Palib. ex Maire [= P. laricio Poir. subsp. calabrica (Loud.) Cesca and Peruzzi]
Pinaceae Phanerophyte scapose Italo-Corsican Endemic
First record for Basilicata (casual) and Campania (casual)
Specimens: 15-05-18, Mandrano, Monti della Maddalena (Paterno, Potenza province), pastures and roadsides, 1110 m a.s.l., 40.36917° N-15.71119° E, leg. et det. L. Rosati (HLUC); 15-05-18, Mandrano, Monti della Maddalena (Padula, Salerno), pastures and roadsides 1075 m a.s.l., 40.36901° N-15.70758° E, leg. et det. L. Rosati (HLUC).
Note: Several young trees from the nearby reforestation areas where this species had been deliberately planted were observed. It was recorded as alien taxa in others Italian regions (Sardegna, Fruli-Venezia Giulia, Toscana), whereas it is considered native only in Calabria and Sicilia [
16].
Plantago argentea Chaix subsp. argentea
Plantaginaceae Hemicryptophyte rosulate S-European-S-Siberian
First record for Campania
Specimen: 20-7-2014, M. Alburno under M. Panormo (Sicignano degli Alburni, Salerno province), rocky slopes, 1402 m a.s.l., 40.53226° N-15.33386° E, leg. A. Stinca et M. Ravo, det. A. Stinca (PORUN-Heb. Stinca).
Note: Plantago argentea was previously indicated in sensu lato in Campania, thus, here we report the presence of the nominal subspecies [
16].
Plumbago auriculata Lam. [= Plumbago capensis Thunb.]
Plumbaginaceae Nano-phanerophyte Neophyte, S-Africa
First record for Calabria (casual)
Specimen: 02-09-2019, C. da Monacelli (Melicucco, Reggio Calabria), roadside, 117 m a.s.l., 38.445020° N-16.042060° E, leg. et det. C. M. Musarella (REGGIO).
Note. In Calabria, we observed a few individuals growing along the roadside; these had probably escaped from a nearby garden. It is reported as casual alien from almost all the regions of Italian peninsula, except for Umbria, Molise, and Basilicata; in Sardegna it is considered naturalized [
17].
Polygala rupestris Pourr.
Polygalaceae Chamaephyte subshrubs W-Mediterranean
First record for Sardegna and confirmation for Italy
Specimens: 02-11-2005; 14-05-2014; 08-04-2016, Canale Oma Molt (Alghero, Sassari province), garrigues with Rosmarinus officinalis and Viola arborescens, 33 m a.s.l., 40.52452° N-8.33371° E, leg. et det. E. Farris (SS).
Note: In the recent checklist of the Italian vascular flora the presence of this species was considered doubtful in Italy [
16]. We found this species in Sardegna along the coast South of Alghero, where it was usually present, though at low densities in the calcareous coastal garrigues. The nearest known localities of this species, according to Flora Gallica and Flora Iberica are in Provence (S-France) and Balearic Islands (Spain).
Populus ×canescens (Aiton) Sm. [≡ P. alba L. var. canescens Aiton]
Salicaceae Phanerophyte scapose S-European
First record for Sardegna
Specimens: 21-6-2016, Settefratelli, along the road from Codoleddu to the giant’s tombstone (Maracalagonis, Cagliari province), near the creek, 465 m a.s.l., 39.26022° N-9.37907° E, leg. et det. L. Rosati (HLUC); 13-5-1981, Mandas (Mandas, Cagliari province), uscita dal paese verso Sorgono, 30 m a.s.l., 39.65376° N-9.12843° E, leg. et det. I. Camarda (SS); 23-5-1975, Piana di Posada (Nuoro province), 5 m a.s.l., 40.635480° N-9.72371° E, leg. S. Vanelli et B. Corrias (SS); 01-06-2018, Sedda Brandanu, Corongiu (Maracalagonis, Cagliari province), remnants of riparian forest, 140 m a.s.l., 39.29282° N-9.29236° E, leg. et det. E. Lallai (Herb. E. Lallai).
Note: In North Sardegna this species was also reported in a vegetation survey from the Cala Regina (Isola dell’Asinara, Sassari province) by [
78]. In Italy it is widespread and known from all regions except for Liguria. This hybrid was reported for Sardegna by Camarda and Valsecchi [
79] and Arrigoni [
80] but not subsequently considered (by mistake?) in the recent checklist of vascular flora [
74,
16]. In the last checklist of the Italian vascular flora [
16] it is not indicated as a hybrid (i.e.
P. canescens (Aiton) Sm).
Potamogeton pusillus L.
Potamogetonaceae Idrophyte rooted Subcosmopolitan
Confirmation for Campania
Specimen: 16-7-2016, Sele river, Oasi Persano (Serre, Salerno province), lotic freshwaters, 40.60488° N-15.13717° E, leg. et det. L. Rosati et G. Salerno, rev. L. Lastrucci (HLUC).
Note: Outside Campania this species is not known from the southern Italian Peninsula [
16]; it was recently confirmed from Basilicata [
39].
Prangos ferulacea (L.) Lindl. [≡ Laserpitium ferulaceum L.; ≡ Cachrys ferulacea (L.) Calest.]
Apiaceae Hemicryptophyte scapose Mediterranean-Turanian
Confirmation for Lazio
Specimen: 16-7-2015, Monte Tilia, Fondo del Laghetto (Leonessa, Rieti province), secondary grasslands with Brachypodium genuense, marly slopes, 1400 m a.s.l., 42.55842° N-12.95441° E, leg. et det. E. Del Vico (Herb. Del Vico).
Note: Doubtfully reported from Lazio on the basis of a historic record (1914) from Terminillo of Cavara and Grande which had not been confirmed by recent surveys [
81]. On the basis of the record above
Prangos ferulacea is now verified from the Lazio region. This species is, with the exception of Molise, otherwise known from the other regions of the Italian Peninsula [
16].
Puccinellia festuciformis (Host) Parl. subsp. festuciformis [≡ Poa festuciformis Host]
Poaceae Hemicryptophyte caespitose Steno-Mediterranean
Confirmation for Campania
Specimen: 12-6-2014, Patria lake, close to the dewatering pump (Giugliano in Campania, Napoli province), temporary flooded grasslands, 0 m a.s.l. 40.94181° N-14.0235° E, leg. et det. A. Stinca et G. Salerno (PORUN-Herb. Stinca).
Note: Until this discovery the presence of this grass in Campania had been considered doubtful [
16]. Outside Campania this
Puccinellia had been reported from several regions of the Italian Peninsula and considered as extinct in Abruzzo [
16].
Quercus petraea (Matt.) Liebl. subsp. austrotyrrhenica Brullo, Guarino and Siracusa
Fagaceae Phanerophyte scapose Italian endemic
First record for Basilicata
Specimens: 15-6-2015, M.te Serranetta (Abriola, Potenza province), oak forests, 1300 m a.s.l., 40.56351° N-15.81886° E, leg. et det. S. Fascetti (HLUC); 15-8-2002, Serra di Calvello (Calvello, Potenza province), oak forests, 1300 m a.s.l., 40,45683° N-15,77855° E, leg. et det. M.R. Lapenna (HLUC).
Note: This Italian endemic is uncommon in Basilicata, where it is generally found in mixed forests with
Quercus cerris, in relatively xeric habitats on mountain ridges, exclusively on subacid substrata (e.g. Flysch Galestrino). Previously it was recorded only from Calabria and Sicilia regions [
16].
Rosa × bishopii Wolley-Dod [= Rosa micrantha Borrer ex Sm. × R. agrestis Savi]
Rosaceae Nano-phanerophyte
First record for Basilicata
Specimen: 3-6-2011, Fiumara di Laurenzana (Laurenzana, Potenza province), shurbland in dry riverbed, 577 m s.l.m., 40.49004° N-15.9583° E, leg. et det S. Fascetti, conf. E. Lattanzi (HLUC).
Note: Several hybrids into the wild dog roses group have been reported mainly in north-central Europe [
82]; on the other hand, in southern Europe, knowledge concerning existence and distribution of these hybrids is very scarce. As a consequence, chorology for this taxon is not defined.
Rosa montana Chaix × R. villosa L.
Rosaceae Nano-phanerophyte
First record for Basilicata
Specimen: 25-6-2016, Piano Jannace (San Severino Lucano, Potenza province), pastures, 1679 m a.s.l., 39.93977° N-16.19668° E, leg. et det S. Fascetti, conf. E. Lattanzi (HLUC).
Note: Rosa villosa is one of the species of sect.
Caninae DC. that can easily hybridize with other sympatric dog roses [
83]. According to some authors, it is probably the most common hybridogenic species among the dog roses [
84]. To the best of our knowledge, a binomial name for this hybrid does not exist yet. As a consequence, chorology for this taxon is not defined.
Rosa subcollina (Christ) Vuk. [≡ R. coriifolia Fr. f. subcollina Christ]
Rosaceae Nano-phanerophyte European-W-Asian
First record for Basilicata
Specimen: 16-6-2011, Fossa Cupa (Pignola, Potenza province), shrublands, 1000 m a.s.l., 40.55197° N-15.73003° E, leg. et det. S. Fascetti, rev. E. Lattanzi (HLUC).
Note: It is recorded from most of the Italian Peninsula regions.
Rumex maritimus L.
Polygonaceae Therophyte scapose Eurasian
First records for Campania
Specimens: 23-5-2014, near the harbour (Pozzuoli, Napoli province), sea sands, 0 m a.s.l., 40.82935° N-14.11412° E, leg. et det. A. Stinca (PORUN-Herb. Stinca); 2-6-2014, Ponte del Diavolo on the banks of the Patria lake (Castel Volturno, Napoli province), artificial river bank, 1 m a.s.l., 40.92918° N-14.0287° E, leg. A. Stinca et G. Salerno, det. A. Stinca (PORUN-Herb. Stinca); 3-6-2014, along the Canale Vico Patri close by Masseria De Chiara (Villa Literno, Napoli province), artificial river bank, 3 m a.s.l. 40.95818° N-14.04141° E, leg. A. Stinca et G. Salerno, det. A. Stinca (PORUN-Herb. Stinca).
Note: Previously recorded only from Calabria in southern Italy [
16].
Salvinia minima Baker
Salviniaceae Idrophyte floating Neophyte Central-S-America
First record for Europe (casual)
Specimen: 1-7-2019, Petile di Calanna (Calanna, Reggio Calabria province), impluvium, 38.19045° N-15.73117° E, leg. V.L.A. Laface, det. V.L.A. Laface et C. M. Musarella (REGGIO).
Note: Salvinia minima is a non-rooted aquatic fern native to South and Central America. Madeira et al. [
85] report this species as locally introduced for Spain, citing Lawarlee in Flora Europaea [
42]. However,
S. minima is not considered in Flora Europaea, neither in Flora Iberica [
86]. For this reason, it may be that this record for Calabria is not the first for Italy but also for Europe. In this context, a case of accidentally introduction of
Salvinia minima in Europe has been only documented in the botanical garden greenhouses in Jibou, Romania [
87]. Detailed images of plants collected in Calabria are shown in
Figure A2. The collected plants were identified using [
88,
89,
90,
91]; diacritical characters useful to distinguish
S. minima with respect to the most similar taxa are shown in
Table A2.

Sempervivum tectorum L.
Crassulaceae Chamaephyte S-European
First record for Basilicata
Specimen: 15-6-2019, M. Volturino (Marsico Vetere, Potenza province), siliceous rocks and cliffs, 1500 m a.s.l., 40.4026° N-15.81642° E, leg. L. Rosati et G. Potenza, det. L. Rosati (HLUC).
Note: Present in central and northern regions of Italy but in southern regions, records of it from Puglia, Basilicata, and Calabria have been treated as mistakes [
16]. Therefore, the discovery of Mt. Volturino reported here now confirms its presence in the southern Apennine.
Solandra maxima (Sessé and Moc.) P. S. Green [≡ Datura maxima Sessé and Moc.]
Solanaceae Phanerophyte climbing Neophyte, Central America
First record for Calabria (casual) and Sicilia (casual)
Specimen: 9-8-2019, Ferrito (Villa San Giovanni, Reggio Calabria province), roadside, 34 m a.s.l., 38.23229° N-15.64493° E, leg. V.L.A. Laface, det. V.L.A. Laface, C.M. Musarella et G. Spampinato (REGGIO); 5-7-2019, Canalicchio (Catania), road escarpment, 91 m a.s.l., 37.53119° N-15.09410° E, leg. C.M. Musarella, det. C.M. Musarella et G. Spampinato (REGGIO).
Note: Solandra maxima was recorded for the first time in Europe from the Campania region [
92]. Our two records are therefore the second for the Italian peninsula and the first for Calabria and Sicilia respectively.
Tagetes erecta L. [= T. patula L.]
Asteraceae Therophyte scapose Neophyte, Central American
First record for Basilicata (casual)
Specimen: 3-8-2017, Porto (Maratea, Potenza province), crevices in road pavements, 16 m a.s.l., 39.98889° N-15.70958° E, leg. A. Stinca et M. Eviano. det. A. Stinca (PORUN-Herb. Stinca).
Note: This species has been recorded as casual alien from many Italian regions [
17].
Tetragonia tetragonoides (Pall.) Kuntze [≡ Demidovia tetragonoides Pall.]
Aizoaceae Therophyte scapose Neophyte, Australia and New Zealand
Confirmation for Sardegna (casual)
Specimen: 19-05-2013, Golfo di Orosei, Cala Gonone (Orosei, Nuoro province), cobble beach, 1 m a.s.l., 40.28270° N-9.63620° E, leg. et det. P.J. de Lange (AK).
Note: Flowering and fruiting plants have been observed (see
https://inaturalist.nz/observations/1509928). In Italy it was previously reported in Friuli Venezia Giulia, Trentino-Alto Adige, Lombardia, Toscana, Lazio, Campania, and Sicilia regions [
17]. Prior to this record this species was known from Sardegna on the basis of old reports that required confirmation [
17].
Trifolium spumosum L.
Fabaceae Therophyte scapose E-Steno-Mediterranean
Confirmation for Basilicata
Specimen: 16-6-2014, Anglona Sanctuary (Tursi, Matera province), dry grassland, 262 m a.s.l., 40.2449° N-16.55653° E, leg. G. Salerno et M.R. Lapenna, det. G. Salerno (Herb. Salerno).
Note: The presence of this species in Italy was ascertained only from Sardegna, Sicilia, Calabria, and Lazio [
16]. In recent times this species has not been recorded from most of the Italian peninsular regions [
16]. Our discovery from Basilicata confirms its continued presence from at least part of that region.
Urginea fugax (Moris) Steinh. [≡ Anthericum fugax Moris]
Asparagaceae Geophyte bulbouse W-Mediterranean
Exclusion for continental and peninsular Italy (Basilicata)
Note: In Italy, we can only confirm this species as present in Sardegna [
16], which is consistent with its W-Mediterranean distribution. Accordingly, we regard past records of the species from Basilicata and neighboring regions as erroneous. Although Gavioli [
51] reported the species from Basilicata in 1915 the samples he noted had been lost, so the record cannot be verified. In absence of further specimens of this distinctive plant from the Italian Peninsula we suggest that
U. fugax had probably been reported by mistake, because of the confusion with a similar species (likely small size individuals of
Urginea maritima auct. Fl. Ital.). Therefore, we recommend that this species is excluded from the flora of Basilicata.
Veronica spicata L. subsp. fischeri (Trávn.) Albach [≡ Pseudolysimachion spicatum (L.) Opiz subsp. fischeri Trávn]
Plantaginaceae Hemicryptophyte crawling Eurasian
First records for Lazio
Specimens: 2-7-2015, Monte Rosato (Poggio Bustone, Rieti province), secondary grassland with Bromopsis erecta, Carex humilis and Plantago argentea, calcareous slopes, 1300 m a.s.l., 42.51662° N-12.88791° E, leg. et det. E. Del Vico (Herb. Del Vico); 10-7-2016, Monte Rosato (Poggio Bustone, Rieti province), secondary grassland with Bromopsis erecta, calcareous slopes, 1350 m a.s.l., 42.51387° N-12.88557° E, leg. E. Del Vico et L. Facioni det. E. Del Vico (Herb. Del Vico).
Note: In Italy this taxon has a northern (Lombardia, Trentino-Alto Adige, Veneto) and central (Marche, Umbria, Abruzzo) disjunct distribution [
16]. In Piemonte it is recorded by mistake [
16]. Subspecies identification of our samples was based on the key reported in [
20]; however, in our view the subspecies delimitation of
V. spicata as stated in [
20] is unclear and needs further study.
Viola kitaibeliana Schult.
Violaceae Therophyte scapose European-Caucasian
Confirmation for Campania
Specimen: 1-3-2016, Campitello, M. della Maddalena (Padula, Salerno province), pastures on siliceous schistous substrate, 1300 m a.s.l., 40.34573° N-15.69029° E, leg. et det. L. Rosati (HLUC).
Note: Viola kitaibeliana is recorded from most of the peninsular regions, except for Emilia-Romagna, Molise, and Puglia; it was previously considered as doubtfully present in Campania [
16]. Our discovery now fills this gap along the Apennine chain.
Wisteria sinensis (Sims) Sweet [≡ Glycine sinensis Sims]
Fabaceae Phanerophyte climbing Neophyte, E-Asia
First record for Calabria (casual)
Specimen: 2-9-2019, C. da Monacelli (Melicucco, Reggio Calabria province), roadside, 118 m a.s.l., 38.44528° N-16.04166° E, leg. et det. C.M. Musarella (REGGIO).
Note: A few individuals of
Wisteria sinensis were noted growing together with
Phyllostachys aurea and
Plumbago auriculata along the roadside, probably escaped from a nearby garden. Previously
Wisteria sinensis was recorded as casual alien from almost all of the Italian regions but only from Campania in the southern ones [
17]. In Sardegna it is considered naturalized [
17].
