Seed germination reports for coastal sand dune species from Sicily
2019
This study investigated seed germination in nine psammophilous species occurring in Sicilian sand dunes, some of which, such as Muscari gussonei, Launaea resedifolia and Pancratium maritimum, are endemic and/or rare and very scattered in the area. Different germination protocols were tested for one or more populations and the best germination results per species are provided, reporting experimental conditions and specific comments on the germination behaviour.
Le piante allergeniche dei Parchi e Giardini Siciliani
La ricerca effettuata presenta la consistenza della componente vegetale legnosa dei giardini e parchi siciliani implicato nelle pollinosi. Quantitativamente, tale patrimonio non si discosta molto da quello dell’Italia peninsulare. Dal punto di vista qualitativo, invece, presenta significative caratteristiche distintive, costituite principalmente da piante subtropicali, esotiche, assenti o rare nel resto d’Italia, ma più o meno frequenti anche in altre aree del Mediterraneo centrale quali l’intero arcipelago siciliano, include Malta, la costa nordafricana, ecc. In particolare rispetto alla sola frazione legnosa (l'intera flora dei giardini siciliani comprende circa 740 specifici taxa), tale …

CAN HALOPHILA STIPULACEA OUTCOMPETE CYMODOCEA NODOSA? A CASE STUDY OF A MEDITERRANEAN SHALLOW WATER HABITAT
2022
The tropical seagrass Halophila stipulacea (Forsskål) Ascherson entered the Mediterranean Sea through the Suez Canal more than 100 years ago. In the coastal-marine ecosystems the spatial niche of H. stipulacea is often overlapped with that of native Mediterranean Sea seagrasses and therefore it might out-compete them. On the basis of previous observations, we monitored for one year a Southern Mediterranean shallow water habitat (North-Western Sicily Island, Italy, Southern Mediterranean Sea), where H. stipulacea co-occurred with the native seagrass Cymodocea nodosa (Ucria) Ascherson. In this paper we compare sites with (impacted sites) and without H. stipulacea (non-impacted sites) to analy…

Nomenclatural notes on the Polycarpon tetraphyllum aggregate (Caryophyllaceae)
2015
Nomenclatural notes on the aggregate Polycarpon tetraphyllum (Caryophyllaceae) are discussed. The names Hagaea alsinifolia, H. polycarpoides, Poycarpon colomense, P. diphyllum, and P. floribundum are typified, respectively, on an iconography by Boccone (lectotype), and specimens preserved in PAL (neotype), JE (lectotype), MA (Herbarium Cavanilles, lectotype), and COI (Herbarium Willkomm, lectotype). For the nomenclatural purposes, the names P. bivonae (nom. nov. pro P. polycarpoides), P. herniarioides (holotype in K), P. peploides (nom. superfl. et nom. illeg. according to the Arts. 52.1 and 52.2 of the ICN), P. polycarpoides subsp. catalaunicum (holotype in BC), and P. rotundifolium (holot…

2014
Hyacinthoides kroumiriensis El Mokni, Domina, Sebei& El Aouni, a new species in Hyacinthaceae from Kroumiria region, North West of Tunisia, is described and illustrated. Morphological characteristics with illustrations, habitat and description of the new species are provided, in addition to a diagnostic comparison with one phenotypically similar species within the same clade.
Nuovi ospiti di Inonotus tamaricis (Hymenochaetaceae) in Sicilia
2010
L’autore segnala T. arborea var. arborea, T. africana var. fluminensis e T. rosea quali nuovi ospiti di Inonotus tamaricis, agente di carie bianca. Si tratta di tamerici coltivate e spontanee, ampiamente diffuse nel territorio, che vegetano in condizioni precarie e di stress principalmente a causa di interventi di potatura poco razionali e del forte inquinamento.

Indagine biosistematica su Scilla sensu lato in Italia e generi affini
2008
The taxonomic assessment of the genus Scilla s.l. and its related genera growing in Italy is defined based on literature data and our own morphological, karyological and phenological studies. A cladistic analysis is also performed in order to test taxonomic role of the selected diagnostic characters. Results agree with the most recent revisions and give support for the proposed synoptical key.
