Ethnobotanical uses of wild taxa as galactagogues in Sicily (Italy)
2018
<p>Breastfeeding furnishes optimal nutrition, immune support, and a multitude of health benefits to mothers and newborns. Since ancient times plants have been employed as galactagogues in the folk medicine of many human cultures. In Sicily, a region with great floristic diversity in the Mediterranean area, where a conspicuous pool of species is traditionally used for food and aromatic, cosmetic, handicraft, agricultural, forestry, and medicinal purposes, some people recognize the galactagogue properties of some spontaneous plants.</p><p>The goal of this study was to identify wild plants with galactagogue properties and vegetable-food remedies traditionally used by women du…
A contribution to the knowledge of myxomycetes diversity in volcanic islands
2015
A list of myxomycetes collected in Pantelleria, a volcanic island located 110 km southwest of the island of Sicily ( Italy), is presented with data on distribution. Forty-nine taxa were identified, 38 of which are new for Sicily. The myxomycete diversity of Pantelleria was also compared with that of other volcanic islands located in the Atlantic and Pacific oceans.

Plant adaptation to drought: evidence and morpho-anatomical diversity in Kali species (Amaranthaceae) from inland and coastal sites.
2017
This study was performed on 6 species of Kali from different habitats and bioclimatic conditions in order to determine the structural differences and variability rate between plant populations from maritime and inland areas, particularly morpho-anatomic functional traits of stem and leaf which allow them to survive under specific environmental conditions.
The Libyan Collections in FI (Herbarium Centrale Italicum and Webb Herbarium) and Studies on the Libyan Flora by R. Pampanini – Part 2
2016
This work is the continuation of Part 1, published in 2015, and comprises the reconstruction of the original collections of new taxa described by R. Pampanini and other botanists and, where possible, typification of the new names and taxonomical updating. The material studied for the most part concerns Libyan specimens held in the FI and FI-W herbaria but in some case also K, LD, MPU, P, PAD, PAL, ULT. Other material, which Pampanini studied in Florence was subsequently conserved in other herbaria. Specimens belonging to 21 families have been examined, from the Najadaceae to Zygophyllaceae. As well as typification, bibliographical data have been provided for those already typified. In this …

Preliminary data on the occurrence of alien macroalgae in the vermetid reef along the coasts of Favignana Island (Southern Tyrrhenian Sea)
2017
Intertidal vermetid reefs are highly diverse systems that provide numerous habitats for animal and vegetal species, leading to an increase of intertidal biodiversity. These habitats, particularly vulnerable to environmental changes and human activities, are now experiencing high mortality in several areas of the Mediterranean Sea. Since alien macroalgae are nowadays considered one of the most serious threats to biodiversity and natural ecosystem functioning, we provide a first baseline assessment of the occurrence of alien species in the vermetid reef along the coasts of the Island of Favignana (Egadi Islands Marine Protected Area). Surveyes carried out in 2015 revealed the only presence of…
Allium achaium Boiss. & Orph. ex Boiss. (Alliaceae), a critical species of Greek flora
2011
Allium achaium Boiss. & Orph. ex Boiss. (Alliaceae), a critical and misappreciated species of Greek flora is investigated from taxonomic point of view and illustrated. It belongs to A. sect. Codonoprasum and shows close relationships with the taxa of the A. stamineum Boiss group. Besides, its karyology, ecology and distribution are examined.
Allium makrianum (Alliaceae), a new autumnal species from Greece
2010
Allium makrianum is described as a new species growing on the limestone of the Chios, north-eastern Aegean island (Greece). It is a very rare autumnal geophyte, showing some relationship with A. archeotrichon from Rhodos. Its iconography, morphology, chromosome number (2n=16), leaf anatomy, ecology and taxonomy are examined.
