The inventory of the taxa collected in 2021 during the annual field trip of the Working Group for Floristics, Systematics, and Evolution of the Italian Botanical Society is reported. The field trip was held in the Mount Pennino massif, between Umbria and Marche administrative regions (central Italy). The flora documented for the study area amounts to 413 specific and subspecific taxa (including one hybrid), belonging to 234 genera and 64 families. Thirty-seven taxa are endemic to Italy; 42 are included in the IUCN Red List of the Italian Flora. Only three alien taxa were found. Ten taxa and one hybrid are considered floristic novelties because either new or confirmed for the regional flora of Umbria and/or Marche. Particularly, 6 taxa are new and 4 are confirmed for Umbria; one taxon and one hybrid are new for Marche.

In this paper, the results of the field trip of the Working Group for Floristics, Systematics, and Evolution of the Italian Botanical Society held in 2021 in the Mount Pennino massif (central Apennines), organised by the botanists of the Herbarium Universitatis Camerinensis (School of Biosciences and Veterinary Medicine, University of Camerino, Camerino) are presented. Floristic excursions of this Working Group are traditionally aimed at exploring poorly known areas from the floristic point of view and publishing the related data (e.g.
The incentive for the organization of the field trip has come from the observation of Andrea Batelli (1854–1917), a botanist and professor at the University of Perugia (
Mount Pennino is forgotten; it can be called a second-rate mountain in that area of famous mountains. It is the story of the bad neighbours to which it owes his misfortune. On the one hand, Mount Subasio contrasts with the celebrity of history, on the other, the Sibillini Mountains with that of altitude, the pious legend that proclaims the eternal brotherhood of men with nature, and the woolly edelweiss, a reminder of the Alps, are the enemies of the misty colossus. But mediocrity must still have its historians, even more so when it has many reasons to be rightly celebrated (
Batelli explored Mount Pennino and surrounding areas at the end of the 19th century, reporting 104 taxa (1886, 1887b). We must admit that more than 130 years later, the above considerations are still valid, as the knowledge about the vascular flora of this area has not increased so much. A few reports indeed have been published, most of them being single records of taxa new to the flora of Umbria (
The “Anarchive” database (http://www.anarchive.it/anArchive/index.jsp) hosts 60 specimens’ records, referred to 46 taxa, collected in Mount Pennino massif by F. Pedrotti (CAME) and V. Marchesoni (CAME, FI) in 1962, G. Zodda (AQUI) in 1967, A. Gabellini (SIENA) in 1999, F. Falcinelli (PERU) in 2006, 2011, and 2012, F. Falcinelli and D. Donnini (PERU), S. Ballelli, D. Gigante, and R. Venanzoni (PERU), and S. Ballelli, D. Gigante, L. Gubellini, F. Landucci, F. Maneli, and R. Venanzoni (PERU) in 2009.
Thus, in 2021 we decided to address the yearly floristic investigation in such area, because largely unexplored in the recent decades.
The study area is localized in the Nocera Umbra (Perugia) and Fiuminata (Macerata) municipalities, in the Rivers Topino and Potenza valleys (WGS84: 43.101210°N, 12.888778°E, coordinate system WGS84; Fig.

From the geological viewpoint, the Mount Pennino massif is characterized by limestone bedrock (
Yearly average rainfall ranges between 1,200 and 1,300 mm (data drawn from Bagnara and Annifo meteorological stations,
The forest vegetation is dominated by coppiced Fagus sylvatica subsp. sylvatica woods and, secondly, by Quercus cerris L. and Ostrya carpinifolia Scop. woods. Grasslands are characterized by Bromopsis erecta (Huds.) Fourr., Brachypodium rupestre (Host) Roem. & Schult., Sesleria nitida Ten., and S. juncifolia Suffren.
To maximize vascular flora sampling, the study area (about 700 hectares) was divided into six sectors (Fig.

The taxonomic identification was carried out at first by the single collectors using standard floras (e.g.,
A revision of the critical samples collected during the fieldwork was carried out by the participants on 23–25 February 2022, at the Herbarium Universitatis Camerinensis (School of Biosciences and Veterinary Medicine, University of Camerino, Camerino). This revision was followed by specific studies and comparisons of unidentified taxa. Particularly, some herbarium specimens belonging to critical genera were sent to experts for determination: Anthoxanthum L., Brachypodium P.Beauv., and Koeleria Pers. (E. Banfi, Milano); Anthyllis L. (F. Conti, Barisciano); Armeria Willd. (M. Tiburtini, Pisa); Hieracium L. (G. Gottschlich, Tübingen); Juniperus L. (F. Roma-Marzio, Pisa); Orobanche L. (G. Domina, Palermo); Thymus L. (F. Bartolucci, Barisciano).
The nomenclature used to draw up the floristic list (see Suppl. material
Abbreviations or symbols used in the floristic list are:
E Italian endemic (
A alien taxon [CAS (Casual), NAT (Naturalized)] (
* taxon confirmed for the regional flora;
** new record for the regional flora.
During the field investigations, 1,461 samples of vascular plants were collected, belonging to 413 species and subspecies, 234 genera, and 64 families (Suppl. material
Anthoxanthum ovatum Lag. and the hybrid Brachypodium retusum × B. rupestre are new to the flora of Marche.
Six taxa are new to the flora of Umbria: Anthoxanthum ovatum, Dianthus carthusianorum subsp. carthusianorum, Erysimum apenninum Peccenini & Polatschek, Hieracium pseudogrovesianum Gottschl., Koeleria lucana Brullo, Giusso & Miniss., Koeleria pyramidata (Lam.) P.Beauv.
Four taxa are confirmed for the flora of Umbria: Cynanchica pyrenaica subsp. neglecta (Guss.) P.Caputo & Del Guacchio, Polygala nicaeensis subsp. italiana (Chodat) Arrigoni, Stachys germanica subsp. germanica, Trigonella elegans (Salzm. ex Ser.) Coulot & Rabaute.
In the Mount Pennino massif, 413 taxa (species and subspecies) were found. Forty–two of them (10.2% of the total floristic list) are currently included in the IUCN Red List of the Italian Flora (
Eleven floristic novelties were reported for the floras of Marche and/or Umbria.
Our records from Umbria and Marche extend the findings of Anthoxanthum ovatum in central Italy. Before this study, its Italian distribution was indeed restricted to Toscana, Campania (historical record), Calabria, Sicilia, and Sardegna (
The records of Dianthus carthusianorum subsp. carthusianorum, Erysimum apenninum, and Hieracium pseudogrovesianum in Umbria, as well as the confirmation of Cynanchica pyrenaica subsp. neglecta, Stachys germanica subsp. germanica, and Trigonella elegans fill a gap in the regional distribution of these taxa in central Italy.
Polygala nicaeensis subsp. italiana was reported only for Emilia–Romagna and Toscana, while it is considered doubtful in Piemonte, not confirmed in San Marino (
Our findings of the endemic Koeleria lucana in Umbria are noteworthy because they are currently the northernmost records of its distribution range (
The natural hybrid between Brachypodium retusum and B. rupestre known also in Toscana (
Some of the specimens collected in the study area, preliminarily attributed to Centaurea arrigonii Greuter, require additional investigations aimed at clarifying their taxonomic identity.
In conclusion, the finding of eleven floristic novelties, the percentage of Italian endemic and Red List taxa in the study area, slightly higher than that of other similar mountain territories in the central Apennines (
We are grateful to E. Banfi (Milano), F. Conti and F. Bartolucci (Barisciano), G. Domina (Palermo), G. Gottschlich (Tübingen), M. Tiburtini and F. Roma-Marzio (Pisa) for the identification of some critical samples.
