Contribution to the floristic knowledge of Sillaro, Santerno, and Senio high valleys (Toscana, Italy)

Abstract

The inventory of the taxa collected 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 2019 along the Sillaro, Santerno, and Senio high valleys located in Toscana (central Italy). The flora documented for the studied area amounts to 492 specific and subspecific taxa (including five hybrids), belonging to 254 genera and 77 families. Bromopsis caprina, Ophrys appennina, O. classica, Polygala flavescens subsp. flavescens, and Pulmonaria vallarsae subsp. apennina were the only five Italian endemics found in the study area, whereas 28 alien taxa were detected. Finally, nine taxa (seven native and two alien) have to be considered as new records for the regional flora of Toscana.

Italian Vascular Flora: New Findings, Updates and Exploration of Floristic Similarities between Regions

“…The species is sometimes cultivated as an ornamental plant in Italy. It was reported as a casual alien for Lombardia, Trentino-Alto Adige, Friuli-Venezia Giulia, Veneto, Liguria, Emilia-Romagna, Toscana, Umbria and Abruzzo [34,72,73,103]. In Cagli (Marche; Figure 2C), a small population was discovered consisting of a few individuals, probably spread by the seeds of nearby cultivated plants, which grow in the fractures of the floor and an external staircase of a disused building on the outskirts of the town.…”

The vascular flora of Empoli (Tuscany, central Italy)

“…The aim of this study is to present a complete and updated floristic inventory of the vascular flora of Empoli, in the framework of a series of contributions whose goal is to improve the floristic knowledge of Tuscany (Pierini et al 2008;Peruzzi et al 2011;Gestri and Peruzzi 2012, 2013Ciccarelli et al 2015;Gei et al 2016;Pierini and Peruzzi 2014;Roma-Marzio et al 2016;Carta et al 2018;Roma-Marzio et al 2020).…”
