[1] In 1842, the Contessa Fiorini-Mazzanti, as she was then known, lost her husband, father and only daughter within a year and became the sole heir to the large family estates.
Her last work, the Florula del Colosseo was published shortly before her death and described the flora around the Roman Colosseum.
At the age of 74, Fiorini Mazzanti participated in the botanical congress of 1874 in Florence, where, although fatigued by the journey, she enjoyed the personal acquaintances of foreign botanists, particularly those from Germany.
Fiorini Mazzanti usually lived quietly in Rome but often left during the summer months to reside in her hometown, the ancient coastal city of Terracina, Italy.
[2] She died in Rome 23 April 1879[2] and news of her passing spread via the most important European botanical magazines and many dedications followed.
