Notulae to the Italian native vascular flora : 5

In this contribution, new data concerning the distribution of native vascular flora in Italy are presented. It includes new records and confirmations to the Italian administrative regions for taxa in the genera Allium, Arabis, Campanula, Centaurea, Chaerophyllum, Crocus, Dactylis, Dianthus, Festuca, Galanthus, Helianthemum, Lysimachia, Milium, Pteris, and Quercus. Nomenclature and distribution updates, published elsewhere, and corrections are provided as supplementary material.

The text for the new records should be submitted electronically to Chiara Nepi (chiara.nepi@unifi.it).The corresponding specimens 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 2,000 characters (spaces included).
This species has a boreal distribution and, in Italy, it is known for all the northern administrative regions, Lazio and Abruzzo, but not yet for Sardegna (Bartolucci et al. 2018).The species is widespread in Corsica, according to Jeanmonod and Gamisans (2013).The Sardinian population reported here was first found in June 2013 (herbarium specimen preserved in Berchidda, Herb.Calvia) and was observed again in 2016, in a small area along a stream in the eastern basal sector of the Gennargentu.
In Italy, the species is recorded only for Liguria and Sardegna, while it is not been recently confirmed for Toscana (Bartolucci et al. 2018 This species is endemic to southern Italy (Peruzzi et al. 2014(Peruzzi et al. , 2015)); it is known for Molise, Campania, Basilicata, and Puglia (Del Guacchio 2010, Bartolucci et al. 2018).To date, the locality reported here represents the southern limit of the species' range.
L.  Pazienza,.-Species confirmed for the flora of Puglia.
Chaerophyllum nodosum is reported as doubtfully present in Puglia (Bartolucci et al. 2018).An ongoing study on the Alfonso Palanza Herbarium preserved in BI allowed to trace two 19 th century specimens collected in Gravina in Puglia (Bari).Another historical collection by U. Martelli from Cagnano Varano (Gargano) can be found in FI (sub Physocaulis nodosus Tausch).Furthermore, this species was indicated for Ginosa in the Arco Jonico (Tenore 1831) and for Monte Sacro, in the Gargano promontory again (Rigo 1877, sub Physocaulus nodosus Tausch).The new records confirm the presence of this species in all the Apulian areas for which the species was recorded in the past.
G. Pazienza, F. Carruggio, V. Cavallaro, F. Mantino, L. This is an Italian endemic subspecies, reported by Bartolucci et al. (2018) for central and southern Italy excluding Puglia and the islands.The population reported here consists of a small number of individuals.This taxon has also been observed in the "Trullo di Sotto" locality (Poggiorsini, Bari), in the calcareous steppe grasslands related to vegetation of trans-Adriatic and north-Adriatic Carso areas (Forte et al. 2005) According to Davis (1999) and Pignatti ( 2017) it is a NE-Steno-Mediterranean taxon occurring in Greece, the northwestern and western Balkan Peninsula, Sicilia, and peninsular Italy.The records from the four administrative regions in mainland Italy are all recent: Toscana (Mazzoni et al. 2009), Calabria (Di Marco et al. 2011), Basilicata (Bernardo and Caldararo 2015), and Campania (Bamonte 2016).In Lazio, it was observed and collected in 2007 in Ponte San Pietro, close to the border with Toscana, where several hundred individuals grew in mixed Turkey and downy oak wood (L.Peruzzi pers.comm.).It was then cultivated for some years at the Pisa Botanical Garden, but the discovery in Lazio was never published.The current finding comes from a locality not far from Ponte San Pietro in the Fiora river valley, where the local environment (woodland) is particularly favorable due to water availability during the growing season.Here, this taxon grows abundantly on deep fertile volcanic soil.It flowers from late November; leaves either about 2-4 cm long or absent at the onset of flowering.
To date, this species was known in Italy for the main islands, the south and the center of the Peninsula northwards to Lazio, Umbria, and Marche (Bartolucci et al. 2018).It includes six different variants accepted at subspecific rank, four of which recorded for the Italian flora (Valdés and Scholz 2009).Among these, M. vernale subsp.intermedium Prob., described from Algeria and putatively reported for Italy but no longer taken into account (Pignatti 2017), remains unresolved.Certainly, systematic and taxonomic boundaries among these taxa are not clear, with the exception of M. vernale subsp.montianum (Parl.)K.Richt., a morphologically, ecologically and chorologically better circumscribed unit.The Tuscan finding can be attributed to the autonymic subspecies by its culms not sheathed up to the panicle, by the uppermost leaf and the panicle open, with branches not, or scarcely, verticillate.
E. Some young individuals of the species have developed near some adult ones introduced for ornamental purposes in some road-flowerbeds located in the southern part of the city of Pescara.Quercus suber is a western Mediterranean species, spread in Italy in Liguria, Toscana, Lazio, Campania, Puglia, Basilicata, Calabria, Sicilia, Sardegna, and alien in Umbria (Bartolucci et al. 2018).In Abruzzo, the species was present, in the past, in the province of Chieti, as evidenced by various findings discovered in a byzantine settlement of the 6 th -7 th century AD at Crecchio (Sciò 1993).There is evidence that the presence of Q. suber in the region lasted until at least 1700 AD in some areas located along the Adriatic coast (Romanelli 1790).In these places, some existing toponyms refer to this plant.
