Notulae to the Italian native vascular flora: 9

In this contribution, new data concerning the distribution of native vascular flora in Italy are presented. It includes new records, confirmations, exclusions, and status changes to the Italian administrative regions. Two new combinations are proposed. Nomenclatural and distribution updates, published elsewhere, and corrigenda are provided as Suppl. material 1.


Alchemilla filicaulis
This Mediterranean species occurs all across the Italian peninsula, from the northwest to the south-east, but its range was, until now, known to end in Basilicata ( Bartolucci et al. 2018), on the northern slopes of the Pollino Massif. The population of Vallone del Rago, consisting of hundreds of individuals scattered over an area of about 1 km, is found, on the contrary, on Pollino's southern slopes.
L. Peruzzi  Baum (1977; see also Licht 2018), but reported as doubtfully occurring by Bartolucci et al. (2018). We confirm the presence of this species in a different locality within the province of Bari.
G Bromopsis stenophylla was found in shrubby-herbaceous xerophytic and thermophilous plant communities, under sub-Mediterranean and sub-continental climates. This species occurs in two Special Areas of Conservation: "IT1343415 Guaitarola" (GE 646) and "IT1330213 Conglomerato di Vobbia". The fragmented distribution in Italy and the recent findings (Lazzeri 2014) suggest that the distribution of this taxon is incompletely known, mainly because of confusions with closely related taxa.
D  (1897) and Gismondi (1949). However, in the past, Liguria included also the Nice area (now Provence, France), from which all the previous reports originated (Bertoloni 1833). Consequently, Bartolucci et al. (2018) believed that the indication for the current Liguria administrative region was a mistake. Instead, the species certainly occurs in this region, on clayey soils along the sloping coastal strip of the western part (e.g., Borghetto Santo Spirito, Pietra Ligure, Finale Ligure).
G. Galasso, E. Banfi Hypericum hirsutum was reported in Calabria as doubtfully occurring (Bartolucci et al. 2018) based on several records in the so-called area of Alto Ionio Cosentino, published by Vita and D'Errico (1981) and Vita (1989). We confirm the presence of this species in one of these localities. We confirm the presence of this taxon in the Alpi Apuane, where it was recorded in the past by Fiori (1927). We also observed it in other localities, such as Foce di Pianza, above Carrara (Massa-Carrara); summit ridge of Mt. Pelato, in the group of Mt. Altissimo (Massa-Carrara, Lucca); close to le Gobbie, up to the Passo del Vestito, in the group of Mt. Altissimo (Lucca). As stated by Zidorn (2012) Osyris alba is an euri-mediterranean species, previously known in NW Italy only for Liguria (Bartolucci et al. 2018 (Arrigoni 1967). Later, Moris (1827) reported the presence of this species, followed by Angius (1851). More recently, Arrigoni (1967) reviewed several historical records supporting the hypothesis of a natural presence of this species in Sardegna. Many other authors considered this taxon native to Sardegna (Arrigoni 2006;Bacchetta 2006;Camarda and Valsecchi 2008), also supported by Pleistocenic fossil pine pollen records (Del Rio and Pittau 1974;Buosi et al. 2016), and by archaeobotanical studies on several Neolithic to Bronze Age (6000-1200 BCE) settlements (Pittau et al. 2012;De Rita and Melis 2013;Buosi et al. 2015;Melis et al. 2017;Pittau et al. 2018). Given this evidence, we support the status change from introduced to native species in Sardegna.
G. Calvia, G. Bacchetta, G. Bonari This taxon was recorded for "Bosco Isola" (Lesina, Foggia) by Forte et al. (2002), but then as doubtfully occurring by Bartolucci et al. (2018). The presence of a specimen in the BI Herbarium [Lesina (Foggia), 5 May 1999, leg. F. Pantaleo, det. F. Pantaleo, L. Forte (BI No. 31492 Rosa nititula belongs to the R. canina L. group (Klastersky 1968). In the past, several authors considered this rose as a variety of R. canina and in the recent checklist of the vascular flora native to Italy it is considered as a taxonomically doubtful taxon (Bartolucci et al. 2008).
F. Roma-Marzio, P. Liguori, E. Lattanzi  Staphylea pinnata is reported as "doubtfully occurring" in Umbria (Bartolucci et al. 2018). This species was found on the western slope of the Apennines dividing Umbria and Marche on ravines at 600 m a.s.l. near Sigillo within the province of Perugia (Biondi et al. 2002).
