This species occurs in all the northern administrative regions, in Calabria, Basilicata, Sardegna, and Sicilia; in central Italy, it has been recorded only in Toscana (Conti et al. 2005). The population consists of a few dozens of tufts, growing in soil pockets inside the crevices; overall, it covers about 200 m². The site is included in the Natural Regional Reserve “Selva del Lamone” and in the Special Area of Conservation IT6010013 under EU Directive 92/43/CEE.

It is a species with a broad ecological amplitude, growing on several habitat types, such as riverbanks, streams, channels or littoral areas of water reservoirs (Hroudová et al., 2007). In the study area, Bolboschoenus laticarpus forms wide stands in temporarily flooded areas, in contact with a Phragmites australis community.

Botrychium simplex was previously reported in Italy only for Trentino-Alto Adige (Conti et al. 2005), namely for the province of Trento (Marchetti 2004). An account of ancient and recent records from this province was given by Prosser (2000) and by Bertolli and Prosser (2014). Currently, only two growing areas are known in this province. This species is listed in Annex II of the Directive 92/43/EEC. Both populations known in Trentino-Alto Adige are located outside Natura 2000 areas. On the contrary, the population on Mt. Lessini is located inside the Natura 2000 area of “Monti Lessini - Pasubio - Piccole Dolomiti Vicentine (IT3210040)” and, therefore, represents the only confirmed occurrence of the species within the Italian Natura 2000 network. The population found near Podesteria consists of about 10 individuals, growing together with B. lunaria (L.) Sw. (no intermediates were observed). We looked for further populations of B. simplex in the surroundings, but detected only many individuals of B. lunaria. Dibona (2012) reported B. simplex for the Sella Pass, on the side of Val Gardena (Bolzano), but the photograph represents B. lunaria.

Several individuals of different ages occur in a peripheral area of the City Park of Termoli, which occupies the final portion of the Valley of Riovivo. Individuals, mostly young, have settled on the southern slope of the valley, in the northwest exposed area, next to the Adriatic Sea and characterized by dry sandstone substrate. The plants have developed in a clearing of an artificial pine forest of Pinus halepensis Mill. and P. pinaster Aiton, covering the side of the valley., Owing to its adaptability to the Mediterranean phytoclimate, in Italy the species is widely used as an ornamental; in several cases, this has led to its spreading locally as an adventitious plant, e.g., in Friuli Venezia Giulia (Conti et al. 2005), Umbria (Ardenghi and Mossini 2013), Puglia (Buono and Manni 2013), Marche (Olivieri 2015a), and Abruzzo (Olivieri 2015b).

0 EMR. nei monti di Parma, Jan 1842, Barbieri (FI! under the name C. reticulatus). – Species not recently confirmed for the flora of Emilia-Romagna.

Despite the very recent confirmation of the occurrence of C. variegatus in Emilia-Romagna by Bartolucci et al. (2016b), a closer re-examination of the specimen in FI led to its identification as C. etruscus Parl. (see below). The misidentification was due to the poor conservation status of the studied material in PI, which did not allow to confirm the presence of a prophyll (distinctive of C. etruscus and of the whole C. sect. Crocus). However, DNA analysis of the ITS region, carried out on leaf samples from the specimen in PI, definitely confirmed that the population from Boschi di Carrega belongs to C. etruscus. On the other hand, we had the opportunity to examine in FI the specimen on which the historical record of C. variegatus for the region (Parlatore 1858, under the name C. reticulatus) was based, and it clearly refers to this species. Parlatore (1858) also suggested a possible error in the locality reported on the label.

The occurrence of this species in Emilia-Romagna is a matter of debate since a long time. Currently considered as a narrow endemic to Toscana (Carta et al. 2010, Harpke et al. 2015, Peruzzi et al. 2017), it was indeed doubtfully reported for Emilia-Romagna by Mathew (1982: “possibly also near Parma”), recorded by Alessandrini (1983), Alessandrini & Bonafede (1996), Alessandrini & Branchetti (1997), and Mazzoni et al. (2001) for several localities. Later, it was excluded from the regional flora by Carta et al. (2010) based on the confusion, documented in many cases, with the plants currently known as C. neglectus Peruzzi & Carta. However, more in-depth morphological and molecular investigations highlighted that the plants recently recorded as C. variegatus for Emilia-Romagna (Bartolucci et al. 2016b) actually belong to this species. On the contrary, C. etruscus was never recorded before in Umbria. The localities reported here considerably enlarge the range of this species, which is of particular conservational interest: it is protected under the Bern Convention, listed in Annex IVb of Habitat Directive (92/43/CEE), and appears in the IUCN Red List of Threatened species as Near Threatened (Carta & Peruzzi 2011).

Recent molecular studies (Li et al. 2012, Jafari et al. 2015) suggest the merging of the genus Tripolium Nees with Galatella Cass., although this result is not supported by anatomical and micro-morphological evidences (Karanović et al. 2015). Two members of Tripolium occur in Italy [Tripolium pannonicum (Jacq.) Dobrocz. subsp. pannonicum and T. sorrentinoi (Tod.) Raimondo & Greuter], whereas a third [T. pannonicum subsp. tripolium (L.) Greuter] has been erroneously recorded in the past (Conti et al. 2007). Unlike T. sorrentinoi (≡ Galatella sorrentinoi Tod.), T. pannonicum subsp. pannonicum and subsp. tripolium are not provided with combinations in Galatella, which are here proposed.

≡ Lactuca serriola L., Cent. Pl. II.: 29. 1756 [2.VI.1756]

Molecular analyses conducted by Koopman et al. (2001) evidenced that no differences occur between L. serriola L., L. sativa L., L. dregeana DC. and L. altaica Fisch. & C.A.Mey., which are probably conspecific. In particular, L. sativa is a culton (sensuHetterscheid and Brandenburg 1995) of L. serriola domesticated in Egypt (Vries 1997). Thus, according to the approach adopted within the new checklist of the Italian vascular flora (Bartolucci et al. 2016c, Galasso et al. 2016) with respect to wild taxa belonging to the same species of the domesticated ones [see e.g. Beta vulgaris L. subsp. maritima (L.) Arcang., Pyrus communis L. subsp. pyraster (L.) Ehrh.], we here propose a new nomenclatural combination for relocating L. serriola as a subspecies of L. sativa. A former combination at the same rank appeared within a doctoral thesis (Frietema de Vries 1996), but was not published in accordance with Art. 30.8 of the ICN (McNeill et al. 2012).

In Puglia, Lolium pratense s.l. [incl. L. apennninum (De Not.) Ardenghi & Foggi] was recorded for Gargano [Biscotti 2002 sub Festuca pratensis Huds., Licht 2008 sub Schedonorus pratensis (Huds.) P.Beauv.] and Salento (Mele et al. 2006 sub Festuca pratensis Huds.). Biscotti (2002) and Licht (2008) referred to a single collection from 1952 by A. Messeri [Fenaroli 1974 sub “Festuca elatior L. = F. elatior L. pratensis (Huds.) Fiori”]. We traced Messeri’s collection in BI (Gargano, S. Giov. Rotondo, Contrada Campolato, Masseria Corvara, 5 June 1952, leg. Messeri). The plants on the sheet are actually Lolium arundinaceum (Schreb.) Darbysh. In BI, we traced another collection sub “Festuca pratensis Hudson” (Campus Universitario di Bari, 11 January 1991, leg. M. Fontanella), also referable to L. arundinaceum. In Salento, L. pratense was recorded by Mele et al. (2006) in the city of Lecce, but confused it with L. arundinaceum (specimen in LEC!). Lastly, a report under Festuca elatior L. from the Daunian subapennine (Trotter and Romano 1914), that we could not verify, is probably to be referred to L. arundinaceum, too.

The distribution area of Piptatherum holciforme includes the E-Mediterranean Basin, SE Europe, C-Asia, up to the Arabian Peninsula, Ethiopia and Eritrea in Africa (Clayton et al. 2017). According to Clayton et al. (2017), the species includes three subspecies: P. holciforme subsp. abyssinicum Freitag, restricted to Ethiopia, Eritrea and Arabian Peninsula, P. holciforme subsp. longiglume (Hausskn.) Freitag and P. holciforme subsp. holciforme. The last two subspecies occur in Europe (Valdés et al. 2009). In Italy, P. holciforme was recorded for Puglia and Basilicata where it was found in karstic canyons near Laterza (Taranto) and Matera (D’Amico and Terzi 2007, Terzi and D’Amico 2009). Based on the taxonomic revisions by Freitag (1975), the main differences between P. holciforme subsp. holciforme and P. holciforme subsp. longiglume are represented by the length of the spikelet (7-10 mm vs. 9-14 mm), lemma (5-6 mm vs. 7-8 mm), and awn (5-8 mm vs. 11-14 mm). Similar differences between the two subspecies were recorded in Iran where both subspecies occur (Hamzeh'ee and Assadi 2015). The specimens collected in Puglia and Basilicata have a spikelet of 10-11 mm, a lemma of 5-6 mm, and an awn of nearly 10 mm. According to Freitag (1975), lemma size is the most reliable character to differentiate the two subspecies. Therefore, the Italian populations are here assigned to the nominal subspecies.

The Italian distribution of this species was described recently by Lastrucci et al. (2010) and subsequently some updates for Marche came from Gubellini et al. (2014).

= Rhaponticoides calabrica Puntillo & Peruzzi, Folia Geobot. 44(2): 192 (2009) syn. nov.

Rhaponticoides calabrica was described as a new species based on putative differences in chromosome number, capitula floret colour, and width of the scarious margin of the phyllaries as compared with R. centaurium (L.) M.V.Agab. & Greuter (Puntillo & Peruzzi 2009). However, all these differences later turned out to be inconsistent. R. calabrica was reported as having 2n = 30 (Puntillo & Peruzzi 2009), while R. centaurium 2n = 26 (Bianco et al. 1990), until Peruzzi & Perrino (2012) proved this count to be wrong, and to correspond to that of R. calabrica (2n = 30). Florets were described as whitish-rose in R. calabrica (Puntillo & Peruzzi 2009) and purple in R. centaurium (Dostál 1976, Pignatti 1982), but the standard descriptions of the latter species in the floras proved to be wrong, since R. centaurium also has withish-rose florets (Fascetti et al. 2014). Accordingly, the only remaining morphological feature concerns the phyllary scarious margins (putatively wider in R. calabrica). However, according to Fascetti et al. (2014), also this feature is controversial, and seemingly rather homogeneous among all localities from Basilicata (where both species should allopatrically occur, according to Puntillo & Peruzzi 2009). All in all, the treatment of R. calabrica as a heterotypic synonym of R. centaurium better conforms to our current knowledge on the systematics of this biological unit.

This subspecies was reported for the island of Montecristo (Tuscan Archipelago) and Argentario (probably based on some of the above mentioned specimens) by Reales et al. (2004) in their taxonomic study on the genus Salvia sect. Salvia, but not included in the works of Conti et al. (2005, 2007). Formerly it was reported as S. officinalis L. for the Tuscan Archipelago and Argentario by several authors (Caruel 1860–1864, Baroni 1897–1908, Sommier 1900, 1902, 1903, Béguinot 1901, Paoli and Romagnoli 1976, Fossi Innamorati 1989, Baldini 1995, 1998, Bertacchi et al. 2005). Sommier (1902) did not include this species in the Montecristo island flora because he did not consider it as truly native. It is not certain whether this taxon is (or was) native in this area or if it is derived from cultivation, i.e., an alien plant that became subspontaneous-casual in wildlands, at least in Elba and Argentario. It is worth noting that this subspecies is (or was) only present in some islands of the Tuscan Archipelago and in Argentario, now a coastal promontory but once an island of the ancient Tuscan Archipelago. Several exsiccata of Salvia officinalis are conserved at FI and the species was also reported for other Tuscan sites (Caruel 1860–1864, 1870, Del Prete et al. 1991, Camangi and Tomei 2003, Bertacchi et al. 2005, Garbari and Borzatti Von Loewenstern 2006, Pierini et al. 2009), but always considering it as cultivated or derived from cultivation. The only regional site where it seems to be native is Mt. Cetona, in SE Toscana (Bonari 2014).

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

Anzalone et al. (2010) recorded Seseli polyphyllum Ten. for Lazio based on a specimen collected on the Ausoni Mountains (M. Arcano [M. S. Biagio], 5 April 1988, leg. et det. E. Lattanzi, rev. B. Anzalone, Herb. Lattanzi). This exsiccatum was recently revised and identified as Seseli montanum L. subsp. montanum (rev. A. Stinca et M. Ricciardi, 15 February 2014). In Lazio, S. polyphyllum was anciently reported only for the Lepini Mountains at “Vetta della Semprevisa” (Béguinot 1897, under the name S. montanum L. var. polyphyllum Ten.). This record is not attested by any exsiccatum collected by Béguinot. Actually, in GE (S. Peccenini in litt.), GDOR (M. Tavano in litt.) and PAD (R. Marcucci in litt.) there is no Béguinot specimen referring to this taxon. Accordingly, this species occurs only in Campania, where it has been recorded for the Sorrento peninsula (Caputo et al. 1994), island of Capri (Ricciardi 1998) and Partenio mountains (Moraldo and La Valva 1989). Therefore, S. polyphyllum is to be excluded from Lazio.

Spiraea decumbens subsp. tomentosa is an Italian endemic, previously known only in Veneto and Friuli Venezia Giulia (Peruzzi et al. 2014). Its local distribution is reported by Poldini (2002) for Friuli Venezia Giulia and by Argenti and Lasen (2001) for Veneto. The map in Argenti and Lasen (2001) shows occurrences not far from the boundary between Veneto and Trentino. When we visited the Mis Valley in the Veneto Prealps, we were impressed by the rich populations of Spiraea decumbens subsp. tomentosa up to 2-3 km from the boundary of Trentino. For this reason, some days later we looked for this plant on the first cliff belt inside the Trento territory and we found the small population described above. The area was previously well investigated (Festi and Prosser 2000), but targeted research led to this unexpected finding.

Vicia serratifolia certainly occurs in southern Italy, Lazio, Emilia-Romagna, and Lombardia whereas it was historically recorded in Campania and is doubtful in Toscana (Conti et. al 2005, Giardina et. al. 2007, Marzorati et al. 2013, Wagensommer et al. 2014, Ardenghi and Polani 2016, Bartolucci et al. 2016a). Vicia serratifolia is listed in Conti et al. (2005) as V. narbonensis L. subsp. serratifolia (Jacq.) Ces., but it is is clearly distinct from V. narbonensis L. by the number of teeth on leaves, shape of stipules, and number of flowers. Therefore, also according to Schäfer (1973), Bennet and Maxted (1997), and Tison and De Foucault (2014), we prefer to regard it as a distinct species.
