Petagnaea is a monotypic genus restricted to the Nebrodi Mountains in north‐eastern Sicily, represented by P. gussonei . This species is considered a relict palaeoendemic of the Mediterranean Tertiary flora and is classified as Endangered according to the IUCN criteria. Petagnaea gussonei was originally described by Sprengel as Sison gussonei , and...

The Conca d’Oro of Palermo, a plain in NW Sicily of significant historical and agricultural importance, has undergone significant landscape alterations due to agricultural strengthening and urbanization. This paper analyses the evolution of the plant landscape from early human settlements to the present by integrating historical records, cartograph...

Ptilostemon greuteri Raimondo & Domina is a rare Sicilian paleoendemic species. The aim of study was to investigate the micro-morphological features of leaves by light and scanning electron microscopy, to elucidate the phytochemical profile of essential oil (EO), n-hexane (HE) and hydroalcoholic extract (HAE) by gas and liquid chromatographic metho...

Wetlands are among the world’s valuable ecosystems for biodiversity conservation, but they are also among the most threatened habitats, heavily impacted by human pressures and threats. The Mediterranean basin features numerous small lakes, ponds, and pools, whose number and quality are decreasing at an alarming rate, and whose biodiversity is often...

New localities and/or confirmations concerning 104 specific and subspecific plant taxa of Tuscan vascular flora, belonging to 95 genera and 45 families are presented: Baldellia (Alismataceae), Amaranthus (Amaranthaceae), Allium, Ipheion (Amaryllidaceae), Aethusa, Ferula, Magydaris, Trochiscanthes (Apiaceae), Vinca (Apocynaceae), Lemna (Araceae), Ar...

Despite the wide amount of scientific contributions published on alien plant species, their diffusion dynamics, and their interactions with native taxa, it is increasingly difficult to slow down their spreading and their negative impact on habitats. Last recent years, in fact, a sharp rise in the number of new alien plant taxa introduced in Italy a...

A single paragraph of about 200 words maximum. For research articles, abstracts should give a pertinent overview of the work. We strongly encourage authors to use the following style of structured abstracts, but without headings: (1) Background: Place the question addressed in a broad context and highlight the purpose of the study; (2) Methods: bri...

In this contribution, new chromosome data obtained on material collected in Italy are presented. It includes the first count for Dianthus carthusianorum subsp. tenorei, Helosciadium nodiflorum, Hieracium hypochoeroides subsp. cilentanum, H. lesimanum, H. scopolioides, H. terraccianoi. In addition, first Italian counts for Crupina vulgaris, Damasoni...

Chromosome numbers and karyotypes are given for 8 taxa occurring in Greece. Microphotographs and karyotype morphology are provided, and polyploidy in some of them is discussed. Specifically, a polypoid karyotype is recorded in the species Centaurea spruneri s.l. (2n = 10x and 2n = 11x) Muscari spreitzenhoferi (2n = 4x) and Allium neapolitanum (2n =...

The inventory of the taxa collected in 2022 during the annual field trip of the Working Group for Floristics, Systematics and Evolution of the Italian Botanical Society is reported. The field trip was held from 19 th to 22 th April in the islands of Lipari and Panarea (Aeolian Islands, Sicilia). Overall, 1,664 herbarium specimens were deposited in...

The results of the annual excursion of the Working Group for Vegetation Science of the Italian Botanical Society, held in the Egadi Islands, Mount San Giuliano and Mount Cofano (W Sicily) on April 23–27 2022, are presented. This paper includes: (1) general information on the visited sites; (2) geology and geomorphology; (3) climatology and bioclima...

In this contribution, new data concerning the distribution of vascular flora alien to Italy are presented. It includes new records, confirmations, exclusions for Italy or for Italian administrative regions. Nomenclatural and distribution updates, published elsewhere, and corrections are provided as Suppl. material 1.

In this contribution, new data concerning the distribution of native vascular flora in Italy are presented. It includes new records, confirmations, and exclusions to the Italian administrative regions. New combinations in the genera Pilosella and Roemeria are proposed. Furthermore, the name Papaver siculum is lectotypified. Nomenclatural and distri...

The results of a comparative study of the quantitative data of the IUCN risk categories attributed to the endemic taxa of the Sicilian vascular flora are reported. 430 Sicilian strictly endemic taxa has been evaluated by comparing the data of the risk categories attributed by published sources. 400 taxa have received at least one assessment of thei...

Megathyrsus maximus var. maximus is reported for the first time in Italy. This grass native to South-Saharan East Africa, the Arabian Peninsula and Madagascar, now widespread in vast areas including Mauritania, Mali, Egypt, Spain, Middle East, Pakistan, India, Southeast Asia, Indonesia, Australia and the Americas from the southern United States to...

Thanks to the discovery of a new important site in the Trapani Mountains, the distribution of Euphorbia papillaris, a rare plant endemic to N-W Sicily, is revised. On the basis of the unpublished record, one of the two hypotheses on the discovery of the species in Sicily, previously advanced, is here confirmed. Floristic and ecological information...

After a brief review of the recent acquisition in some native genera of family Asteraceae from southern Italy and Sicily, a new endemic species of Anthemis (sect. Hiorthia) is described from Sicily and named Anthemis parlatoreana. The locus classicus of the new taxon, falling in the NW Tyrrhenian coast of the island (Castellammare del Golfo, Trapan...
