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.
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.
Re-evaluation and typification of Foeniculum piperitum (Apiaceae), an underknown medicinal plant and crop wild relative
2021
Foeniculum piperitum was described as Anethum piperitum based on plants collected in Sicily, Italy. Currently it is treated either as a synonym of Foeniculum vulgare, or as one of two subspecies within that taxon. Here we show that F. vulgare and F. piperitum are two different, sometimes co-occurring, taxa and that given clear morphological and ecological separation, they should be treated as distinct species. Anethum piperitum is typified. Owing to misapplication of names and wrong synonymizations, the ecology and chorology of F. vulgare and F. piperitum have to be better defined.

Clinopodium raimondoi (Lamiaceae), a new species from Sicily
2015
On the basis of the taxonomic study of the collections made by F. M. Raimondo, kept in PAL, a new species of Clinopodium is described. The new taxon, named Clinopodium raimondoi, occurs in N-W coast of Sicily on limestone substrata, in steppe communities dominated by Hyparrhenia hirta. The main distinctive characteristics of C. raimondoi, with respect to other taxa known from Europe and other Mediterranean countries, are the large size, the opposite and decussate branches, and the clearly woody at base stems of mature plants as well. Relationships of the new taxon with the Mediterranean ones in the C. nepeta group are also discussed.
Diversity in the population of Brassica incana Ten. (Cruciferae) in Sicily
2014
henotipic diversity in Sicilian populations of Brassica incana Ten. (Cruciferae) is here ana- lyzed in comparison with the only one known population of B. raimondoi Sciandrello et al., taxonomic close species recently described from the coastal relief of eastern Sicily. The analysis of diagnostic characters of these two taxa does not reveal significant differences that justify a treatment at species level of the population of B. raimondoi. On this base, the authors deemed to include this taxon in the infraspecific variability of B. incana and consider most appropriate the rank of subspecies. Therefore is here proposed the establishment of the trinomial com- bination B. incana subsp. raimond…
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.
Nomenclatural remarks on Carex sect. Sylvaticae (Cyperaceae): C. laxula and related names
2018
Our taxonomic and nomenclatural research reveals that the name ‘Carex laxula Tineo ex Boott’ (section Sylvaticae) has not been validly published. Consequently, the oldest available name for the species is Carex paui Sennen. A lectotype for the valid name Carex sylvatica var. laxula Tineo ex Guss. is here designated.
Centaurea heywoodiana (Asteraceae), a new species from the Nebrodi Mountains (NE-Sicily)
2020
A new endemic species of Centaurea is here described from the Nebrodi Mountains, in Sicily, and named Centaurea heywoodiana. Information on its morphology, distribution, ecology and taxonomic relationship is also provided.
Orobanche apuana (Orobanchaceae) a new species endemic to Italy
2015
Orobanche apuana , a new species belonging to Orobanche sect. Orobanche , is described and illustrated from the Apuan Alps, Central Italy. Its relationships with the other species of the group of O. caryophyllacea ( O . grex Galeatae ) and with other Orobanche that parasitize Santolina species are examined. The names Boulardia latisquama , Orobanche lutea and O. teucrii are here lectotypified.
