Riassunto

Sono state effettuate, durante gli anni 1988–1991, ricerche floristiche nella valle del torrente Farma situata nel comprensorio delle Colline Metallifere (Italia centrale). Questa valle si estende per circa 120 Kmq. ed è caratterizzata dall'elevata percentuale di superficie boscata. Lo studio, svolto nell'ambito di una serie di ricerche geobotaniche sull'intero bacino del fiume Merse, ha permesso di portare la flora vascolare conosciuta per la Val di Farma a 708 entità, tra le quali specie rare o con diffusione frammentaria. Una di queste, Lupinus graecus Boiss. et Spruner, è stata solo recentemente inclusa nella flora italiana e la stazione della Val di Farma risulta attualmente la segnalazione più settentrionale del suo areale.

During the years 1988–1991 floristic research has been carried out in the valley of the Farma river, located in the Colline Metallifere area (central Italy). This valley covers about 120 Km2 and is characterized by a high percentage of woody areas. From our study, developed within a project of geobotanical research on the whole basin of the Merse river, the known vascular flora for the Farma valley amounts to 708 entities. Some of the species found are rare in central Italy or of scattered distribution. One of these, Lupinus graecus Boiss. et Spruner, has been only recently recorded in Italy, and its presence in the Farma valley is the most northerly of its range.
