TAXONOMIC, ECOLOGICAL AND CHOROLOGICAL REMARKS ON CLINOPODIUM MINAE (LAMIACEAE), CRITICAL AND RARE PLANT OF THE SICILIAN FLORA
2017
In a previous contribution (1) the finding in the wild of Clinopodium minae (Lojac.) Peruzzi & F.Conti [Bas. Calamintha minae Lojac.], a critical species close to Clinopodium corsicum (Pers.) Govaerts and well distinct from Clinopodium alpinum (L.) Kuntze subsp. nebrodense (A.Kern. & Strobl) Bartolucci & F.Conti was reported. It is a critical taxon, described by Lojacono, author of the most extensive work on the Sicilian flora (2) based on the examination of the collections of the Herbarium of Palermo (PAL!) (3). In the above cited note, the specific characters as well as the taxonomic relationships with other taxa were highlighted. At the same time, the location of a small population of C.…

Araucaria columnaris (Araucariaceae) casual alien in Sicily
2021
The first case of spontaneous regeneration of Araucaria columnaris in Europe is reported. Data are given on the taxon and on the Sicilian site where A. columnaris - native to New Caledonia (Australia) - tends to spread autonomously.
Distribution and ecological role of selected shrubby species in the Mediterranean basin
2019
In many natural and semi-natural habitats trees and shrubs represent two major growth forms (1). In particular shrublands, which can be considered a mixture of several sclerophyllous shrubs and tree species, represent a Mediterranean type of vegetation rarely found in other ecosystems. The distribution of shrubs in an ecosystem is connected to complex ecological processes. Indeed, shrubs provide substrate, food and shelter for organisms, play an important role in the nutrient cycle providing organic matter input to soils and they protect watersheds from erosion. Moreover shrubs are very important for many associated species such as mammals, birds, invertebrates, other plants (that favour th…
Inocybe castaneicolor (Agaricales, Basidiomycota), a new species in section Splendentes
2017
Inocybe castaneicolor sp. nov., collected in Sicily (Italy), is introduced with full description, line drawings, and color pho- tographs. Its novelty is supported by both its morphology and molecular phylogenetic analysis. It is characterized by its castaneous brown pileus with an evident umbo and sloped margin, subfusiform cystidia and smooth subamygdaliformis to subnavicular spores. Comparison of I. castaneicolor with similar species is also provided.

Segnalazione per la flora siciliana di Trifolium ornithopodioides L. (Fabaceae) e revisione della sua area di distribuzione.
2011
Trifolium ornithopodioides (L.) Sm. (Fabaceae) a new record for the Sicilian flora – T. ornithopodioides, a rare element of the Italian flora, is recorded for the first time in the territory of Palermo (Western-Sicily). The population identified, consisting of about one hundred individuals, colonizes a narrow area between the roadside and the edge of the freshwater temporary pond of Rebuttone, on acidic substratum (flysch) at 720 m a.s.l. After the examination of herbarium specimens (RO and FI) and literature, some incongruences have been found on the Italian distribution of this taxon. A distribution map including the new record, new literature data and corrections is presented.
Festuca humifusa (Gramineae), a new species from Sicily.
2001
Festuca humifusa, a new species from Cape Tyndaris (NE-Sicily) is described and illustrated. Its ecology, distribution and relationships with the allied species are discussed.

Checklist of the vascular plants collected during the 12th “Iter Mediterraneum” in Tunisia, 24 March – 4 April 2014
2015
The vascular plants (plus one alga) collected during Iter Mediterraneum XII of OPTIMA in North Tunisia have been studied. In all, 1374 gatherings were made from 43 localities in the “Cap Bon” region, “Dorsale Tunisienne”, “Tunisie du Nord-Est”, “Vallée de la Medjedah”, “Mogods” and “Kroumirie” areas. They belong to 82 families and 539 species or subspecies. Three taxa are new for the flora of Tunisia (Cerastium diffusum subsp. gussonei, Senecio leucanthemifolius subsp. mauritanicus, and Ulmus minor subsp. canescens), 7 represent new records for the “Kroumirie”, 15 for the “Mogods”, 3 for the “Tunisie du Nord-Est”, 2 for the “Dorsale Tunisienne”, and 8 for “Cap Bon”
