Introduction
My research interest lies in taxonomic and systematic studies on vascular plants of the Mediterranean flora, with a special focus on Italian endemics, lilioid bulbous geophytes and carnivorous plants. I am also interested in cytotaxonomy, plant ecology and conservation, and online databasing of karyological and floristic data (Chrobase and Wikiplantbase projects).

Article
Quantitative parameters have been used to characterize chromosome number (CN) variation. This gave us the idea to collect available data in various organisms and compare them, in order to verify if variation patterns differ between animal and plant groups and to quantify these patterns with an Index of CN Heterogeneity (ICNH), useful as a parameter...

Until now, basic karyological parameters were used in different ways by researchers to infer karyological relationships among organisms. In the present study, we propose a standardized approach to this aim, integrating six different, not redundant, parameters in a multivariate PCoA analysis. These parameters are chromosome number, basic chromosome...

The census of the loci classici of 1,400 Italian endemic vascular plants (i.e. not thriving elsewhere with the exception of Corsica and Malta) is here presented and described. The effective place of publication of accepted names, basionyms and homotypic synonyms were identified and critically verified. This often resulted in some change in authorsh...
Article
The software KaryoType, an improved and completely renewed version of the previously existing NucType, was developed for plant chromosomes. The primary function of the software is to allow efficient chromosome measurements and karyotype analysis from microphotographs. Karyotype characterization usually includes chromosome number, size, arm ratio, c...
Article
Chromosome number and genome variation in flowering plants has stimulated a blossoming number of speculations about the ancestral chromosome number of angiosperms, but estimates so far remain equivocal. We used a probabilistic approach to model haploid chromosome number (n) changes along a phylogeny embracing more than 10 thousands taxa, to recons...
Article
An alphabetical list of all the validly published names of the genus Trichospermum, including those first published in Althoffia, Belotia, Bixagrewia, Diclidocarpus, Graeffea, Halconia, and Eroteum, is presented. We provide details of all nomenclatural types, including thirty new typifications (twenty-one lectotypifications, one second-step lectoty...

Three subspecies of Armeria arenaria are reported from Italy, two of which are considered endemic to the Apennines. The taxonomic value of these two taxa (A. arenaria subsp. marginata and A. arenaria subsp. apennina) is unclear. Moreover, the relationships between A. arenaria subsp. praecox and Northern Italian populations—currently ascribed to A....
Article
Floristic inventories are crucial for research in botany, but they are still conducted following a purposive approach. To overcome this limitation and move towards a next generation floristics, we propose a workflow, which integrates novel methods and tools in (a) Species-Area Relationship, (b) floristic cartography, and (c) sampling algorithms.

Silene neglecta has been misunderstood and confused with S. nocturna, although several morphological characters (petal shape, calyx indumentum, hairiness of stamen filaments, seed size, seed-coat surface and shape) allow separation of the species. Moreover, S. mutabilis (which has been considered conspecific with S. neglecta) and S. martinolii (an...
Article
The vast amount of occurrence records currently available offers increasing opportunities for biodiversity data analyses. This amount of data poses new challenges for the reliability and correct interpretation of the results. Indeed, to safely deal with occurrence records, their uncertainty and associated biases should be taken into account. We dev...
Article
Herbaria may represent remarkable sources of viable diaspores for recovering lost genetic variation and extinct plant species, but the application of rewilding extinct species using these collections has not been explored in detail. De-extinction in plants may be achieved by germinating viable diaspores or culturing tissues preserved in herbarium s...

Santolina is a plant genus of dwarf aromatic shrubs that includes about 26 species native to the western Mediterranean Basin. In Corsica and Sardinia, two of the main islands of the Mediterranean, Santolina corsica (tetraploid) and S. insularis (hexaploid) are reported. Along with the cultivated pentaploid S. chamaecyparissus, these species form a...

Data la scarsa variabilità ambientale e l’elevato grado di antropizzazione, il territorio empolese è stato in passato oggetto di scarsa attenzione da parte dei botanici, spesso più attratti da aree di maggiore interesse naturalistico come le montagne o le coste. Da botanico per professione e per passione ho ritenuto quasi un imperativo morale porre...
Preprint
Here, from macrophylogeographic mtDNA empirical data, we proposed a scenario of the evolution and speciation of two important forest trees, European Black Pine and Scotch Pine, and their multiple subspecies and varieties. Molecular clock simulations revealed that INDELs variability in the Pinus mitochondrial genome is relatively old, i.e., from the...
