Aster ageratoides is a native of eastern Asia, increasingly recorded as an escaped across the European continent, where its cultivation for ornamental purposes has become popular in recent years (Yeo 2000, Chen et al. 2011, Verloove 2014a). There is no general consensus about the taxonomic rank: here, in line with Ito and Soejima (1995), we chose the rank of species. The population in Podenzana is composed of about ten individuals scattered along a road edge; the presence of the plant in the site of collection was confirmed in October 2016 (B. Romiti: www.actaplantarum.orgfloraitaliae/viewtopic.php?f=102&t=91873). The identification of the plant was possible thanks to the online forum Acta Plantarum, where some pictures of this taxon have been uploaded.

A further finding in the province of Lecco encouraged us to re-examine specimens kept in MSNM herbarium under the name C. fortunei. All of them belong to C. harringtonii, except for a doubtfully attributable gathering [Mosso (Biella), Mosso Santa Maria, Parco di Palazzo Sella, August 1956, A. Piazzoli Perroni] (Lang et al. 2013). Both species are E-Asian orophytes (C. harringtonii widely spread from western China to Malaysia; C. fortunei is present in China, Laos and Myanmar). In Italy, they occur in botanical gardens, private and public parks, and commerical nurseries. However, it seems that C. fortunei is overall rarer and easily misidentified.

– CAL. – Alien species to be excluded from the flora of Calabria.

Originally native of East Asia, Cyperus microiria is locally naturalized outside its native range, mostly as a weed of paddy fields, for instance in parts of North America (Tucker et al. 2002). In Europe it is only known as a naturalized weed from Italy. Conti et al. (2005) cited this species from Emilia-Romagna, Friuli Venezia Giulia, Lombardia and Piemonte. Soon afterwards, however, it was excluded from Friuli Venezia Giulia (Conti et al. 2007). In turn, Celesti-Grapow et al. (2009) also reported C. microiria from Calabria and Veneto. During a thorough revision of Cyperus in Europe the presence of C. microiria was confirmed in Emilia-Romagna, Lombardia and Piemonte (Verloove 2014b), subsequently also in Veneto (Pellizzari and Verloove in press). In these northern regions, C. microiria is a common weed of rice fields, exposed river banks and similar temporarily damp habitats. Claims from Calabria, however, were geographically quite disjunct and hence potentially suspect. In Calabria, C. microiria was known solely from the natural reserve “Foce del Fiume Crati” (Maiorca et al. 2005, Maiorca et al. 2007, Gangale and Uzunov 2011). A herbarium specimen was recently revised by one of us (F. Verloove). Although immature, it could be ascribed to the very variable native species C. fuscus L. As a consequence, C. microiria should be removed from the flora of Calabria.

Lastrucci & A. Coppi (FI, BR). – Naturalized alien species new for the flora of Toscana.

Cyperus odoratus is a pantropical species, naturalized in many parts of southern Europe and widely confused with Cyperus strigosus L. (Verloove 2014b). The specimens collected in Larciano show an annual behaviour, a low number of spikelets, and short glumes, leading us to determine them as C. odoratus. In the collection site, the species is widely present along the bottom and banks of a canal, at the edge of a vegetation dominated by Phagmites australis (Cav.) Trin. ex Steud. Several authors reported the presence of C. strigosus in the area of Le Morette and some nearby wetlands (Franzese 2004, Franzese 2006, Lastrucci et al. 2007, La Rosa et al. 2008); nevertheless, the specimen preserved in FI relative to the Notula 1439 (La Rosa et al. 2008) belongs to C. odoratus. It is probable that the other reports of C. strigosus from this locality also have to be referred to C. odoratus. Based on a scan from the private herbarium of J.-M. Tison examined by us, the claim of C. strigosus from Pisa (La Rosa et al. 2008) also belongs to C. odoratus. A further record of C. strigosus comes from the “River Arno, near Nave di Carmignano, Prato” (Gestri and Peruzzi 2013). The analysis of this specimen (PI) allows us to exclude C. strigosus; being immature, we cannot confirm with certainty that the specimen belongs to C. odoratus. As a consequence, there seem to be no confirmed records of C. strigosus from Toscana.

López Tirado, det. J. López Tirado & A. Scoppola (UTV–33965, scan in FI). – Naturalized alien species confirmed for the flora of Lazio.

According to Conti et al. (2005) and Celesti-Grapow et al. (2009), the Italian distribution of this species includes gaps and doubtful occurrences. It is a not confirmed alien species in Lazio where its status is controversial. Sanguinetti (1864) reports it from Rome “in incultis et pomariis nonullis. A monte Mario in copia nelle Ville Panfili, Patrizi, etc.”; the author, in fact, collected it in Villa Pamphili (Rome) before 1853 and before 1876 (FI, C. Nepi in verb.). In the surroundings of Viterbo (Monte Palanzana) the species was recorded for the first time by Macchiati (1888). Pignatti (1982) and Conti et al. (2005) report it as escaped from cultivation or as naturalized alien species, whereas Anzalone et al. (2010) consider it a casual species, locally extinct in the wild. The latter authors, however, report a specimen collected in Roma [Bioparco: Villa Borghese, A. Pavesi, 1998 (Herb. A. Pavesi)], referring to an isolated plant that was never recovered (A. Pavesi in verb.). In fact, the species was not confirmed for the Lazio region neither by Pretto et al. (2009), nor by Celesti-Grapow et al. (2013), Nimis et al. (2016) and Iamonico et al. (2012, 2014). Last year, a fruiting specimen was observed under the canopy of Quercus pubescens Willd. subsp. pubescens near the road for Monte Pizzo, not far from Viterbo and very close to the first finding of Macchiati (1888). Some plants have been found recently in the ditch of the same road, spreading as far as several meters from the roadside towards the open oak wood. Thus, we can state that H. nutans is naturalized in the Viterbo surroundings, the only existing settlement of this species nowadays in Lazio.

Young specimens of this species, some more than 2 m tall and with polylobate leaves, grow in the established riparian vegetation along the edges of the Fosso di Tor Carbone, together with patches of Arundo donax L. and scattered trees of Populus nigra L., on alluvial soil consisting of ancient coarse pyroclastic deposits. The plant was tentatively identified as Morus kagayamae Koidz., a Japanese endemic increasingly cultivated as ornamental in Spain (Laguna Lumbreras and Ferrer Gallego 2014), Italy, and France and locally escaped in the latter two countries (Ardenghi and Polani 2016, Tison and de Foucault 2014). However, upon closer examination, it turned out to belong to a very similar species, Morus indica. This taxon is currently referred as Morus australis Poir. (Zou and Gilbert 2003, Iwatsuki et al. 2006), i.e., a posterior synonym (Rao and Jarvis 1986). The main character discriminating the two species consists of minute strigae that are abundant on the adaxial leaf surface giving it a marked roughness; furthermore, the adaxial surface is dull (Iwatsuki at al. 2006). These features are completely lacking in M. kagayamae, the leaves of which are smooth and lustrous, although idioblasts with dot-like tips are present that may cause a very slight roughness (Iwatsuki at al. 2006). The natural range of M. indica comprises Bhutan, China, India, Japan, Korea, Myanmar, Nepal, and Sikkim (Zou and Gilbert 2003); elsewhere the species is cultivated for gardens, parks and road mastings.

Blocking name: Stachys purpurea Poir., Encycl. [J. Lamarck & al.] Suppl. 5. 1: 227. 1817.

In the framework of the new edition of the checklist of the Italian vascular flora (Bartolucci et al. 2016, Galasso et al. 2016), and according to the systematic proposal of Bartolucci et al. (2014), Stachys L. is regarded in its broad sense including also the genus Sideritis L. Sideritis purpurea Fox Talbot ex Benth. is a Balkan endemic (Greuter et al. 1986) described from the Greek islands of Corfu and Zakynthos (Bentham 1835). It is usually regarded as a subspecies of Siderits romana L. (e.g. Heywood 1972, Govaerts 2016), but recognized as independent species in the recent checklist of the Greek vascular flora (Dimopoulos et al. 2013). In agreement with the latter treatment, we propose here a new name for Sideritis purpurea in the genus Stachys. The epithet purpurea is unavailable in Stachys because of Stachys purpurea Poir. (Art. 6.11 of the ICN, McNeill et al. 2012). The new epithet is named after the British scientist William Henry Fox Talbot (11 February 1800 – 17 September 1877). Stachys talbotii was recorded by Murr (1900b) along the railway near the Pergine Valsugana station (Trentino-Alto Adige). At that time, the Valsugana railway had just been built and, along it, extensive greening was carried outusing seeds from Greece. The result was an impressive entrance of Balkan species, several of them new for the flora of Tyrol (Murr 1900a, Murr 1900b, Murr 1901). Stachys talbotii was not recorded in recent times from Italy and should be considered as a casual alien in Trentino-Alto Adige.
