Floristic survey of the former royal hunting reserve of Renda, near Palermo (Sicily, Italy)
2021
A mountainous area in western Sicily, where relic wood vegetation is still preserved notwithstanding past and present human pressure, is here analysed in order to prepare a checklist of its vascular flora. Field investigations allowed to compile a floristic inventory including 601 infrageneric taxa belonging to 304 genera and 80 families. Some remarks on the biological and chorological spectra are presented, and some measures to protect flora and vegetation are suggested, too.
ANREDERA CORDIFOLIA (TEN.) STEENIS (Basellaceae): STATUS IN ITALIA E SUA ESPANSIONE IN SICILIA OCCIDENTALE
2016
In questa nota si fornisce un quadro aggiornato sui casi di naturalizzazione di Anredera cordifolia in Sicilia e sul suo status invasivo a livello nazionale. Questa xenofita viene inoltre segnalata per la prima volta per le province di Agrigento, Palermo e Trapani.
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.
Taxonomic study on Allium dentiferum Webb & Berth. (Alliaceae) and its relations with allied species from the Mediterranean.
2008
Taxonomy and relationships of Allium dentiferum, a polyploid synanthropic Mediterranean species, are assessed based on morphological, karyological and cladistic analysis. A new species, Allium galileum, closely related to A. dentiferum, is described and illustrated. Both species are large and share very long spathe valves, yellow-greenish tepals and interstaminal teeth. The new species, however, is diploid and linked to natural habitats, and is characterized by the lax and spread inflorescence, purple stamen filaments and the smaller perigon, anthers, ovary and capsule. Relationships among these two species and allied taxa of Allium sect. Codonoprasum, such as A. fuscum, A. pallens, A. pani…
The unnoticed northward expansion of Najas marina subsp. armata (Hydrocharitaceae) in the Mediterranean area: an effect of climate change?
2022
Recent reports of Najas marina L. (Hydrocharitaceae) from Sicily have been interpreted as a confirmation of its presence on the island, where it was earlier mentioned in the 1800s. However the recent finds do not represent “N. marina” (currently N. major All.) but N. marina subsp. armata Horn (= N. delilei Rouy), a different taxon, previously not recorded from Sicily. According to those reports and several new finds presented here, it appears to be invading reservoirs and lakes in southern Sicily and seems to be naturally expanding its range. Climate change is suggested as possible cause of this shift. The same trend appears to be taking place across the whole N Mediterranean area, from Por…
Drafting a prioritized checklist of Crop Wild Relatives and Wild Harvested Plants of Italy: problems and solutions
2022
The National checklists of Crop Wild Relatives (CWR) and Wild Harvested Plants (WHP) are the basic tools for the development of in situ and ex situ conservation strategies of plant genetic resources. Here we discuss the methodologies and the prioritization process we previously used in the preparation of the prioritized checklist of CWR and WHP for Italy. The starting point were the most up-to-date Italian checklists of native and alien flora with their updates used as a nomenclatural and distributive source of data. Sardinia and Sicily were kept separate from peninsular Italy to perform detailed analyses focused on the taxa of the two major islands. The origin, the endemic status, cultivat…
Orobanche australis Moris ex Bertol. the correct name for O. thapsoides Lojac. (Orobanchaceae)
2022
The taxonomic relationships between Orobanche australis and O. thapsoides are analyzed through the study of the original material. These species are also compared with other morphologically similar ones occurring in the Mediterranean (O. canescens, O. pubescens, O. palaestina, O. amethystea). The lectotype of O. palaestina is designated. From the comparison of these taxa it is evident that O. australis and O. thapsoides refer to the same taxon, to which the name O. australis must be given by priority. The distribution of this species includes Sardinia, Sicily, Peninsular Italy and Southern France. It grows on pastures from the sea level to about 1000 m of altitude, host of Asteraceae. An id…
