Despite the extensive bio-scientific literature concerning the Mediterranean diet, which emerged in the last three decades, systematic ethnography-centered investigations on a crucial portion of this food system, linked to the traditional consumption of non-cultivated vegetables, are still largely lacking in many areas of the Mediterranean Basin.In this research, an ethnobotanical field study focusing on wild vegetables traditionally gathered and consumed locally, was conducted in a few centers and villages located in the Gargano area, northern Apulia, SE Italy, by interviewing twentyfive elderly informants. The folk culinary uses of seventy-nine botanical taxa of wild vascular plants, belonging to nineteen families, were recorded, thus showing a remarkable resilience of traditional environmental knowledge (TEK) related to wild food plants. In particular, approximately one-fourth of the recorded wild vegetables are still very commonly gathered and consumed nowadays, while ten taxa have never been reported in previous ethnobotanical studies conducted in Southern Italy. These findings demonstrate the crucial cultural role played by folk cuisines in preserving TEK, despite significant socio-economic changes that have affected the study area during the past four decades.

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

In this work, we present a summary of an ethnobotanical research carried out in the whole Administrative Region of Apulia (southern Italy). The main topic of the investigation is the traditional knowledge about wild plants, focusing on their common names, on which parts were used in cooking and how they were used. The main aim was to establish a botanical knowledge about these culinary uses through a systematic identification of the species involved, directly in the field. In addition to this, we focused on the ecological aspects of these species and on their biological and chorological forms. Results suggest the existence of very strong ties between the local communities and this particular flora, without substantial differences between rural and urban areas or among different zones of the Apulia Region. On the other hand, in each area we found peculiar food uses, species, parts used, and recipes. The analysed wild plants still have a fundamental role in the local diet, which can predominantly be ascribed to the Mediterranean model. Moreover, we documented an increasing interest in the culinary uses of these species: in the Gargano area, for instance, more and more cultivations of SalicorniaperennansWilld.subsp.perennans are underway thanks to the demand coming from restaurants. In total, we documented 214 taxa (58 families) and at least 19 of them are enduring components of the local diet. Nineteen species represent a high number, considering that the tertiary sector is nowadays predominant in Apulia (73.5 % of the local GDP, compared to 73.2 % in Italy as a whole). Furthermore, the total amount of wild species used as food is the highest in Italy, according to the Italian ethnobotanical literature. On the same basis, we were able to draft a national checklist of 539 taxa documenting the taxonomy of the wild plants involved in traditional food use in Italy, categorized by regions. In conclusion, this work shows that the available literature regarding the Italian territory provides only a partial representation of traditional food uses, even though they are widespread throughout the country. Consequently, this tradition remains to be thoroughly investigated.

The revision of the Paliurus spina-christi dominated vegetation of Europe is presented here. The study area includes the north-eastern part of Iberian Peninsula and Provence to the west, and spreads through the Apennine Peninsula to the Balkan Peninsula and up to Eastern Mediterranean areas. The phytosociological releves of Paliurus spina-christi dominated vegetation found in the literature for these European territories were gathered together in a phytosociological table. Floristic analysis, cluster analysis, and indirect gradient analysis were performed to determine the similarities and differences between the different Paliurus spina-christi dominated communities and their correlations with the main bioclimatic indices described in the literature. The various analyses highlight the existence of nine different associations (one of which is described here for the first time) that are attributed to different syntaxonomic levels.In the conclusion, a syntaxonomical scheme is proposed that classifies the European vegetation of shrublands in the class Rhamno-Prunetea which includes the class Paliuretea. Currently, we recognized three orders within this class: Prunetalia spinosae for central and south-central Europe; Pyro spinosae-Rubetalia ulmifolii within the Temperate oceanic bioclimate of the sub-Mediterranean variant; Paliuretalia spinae-christi with a central Mediterranean and sub-Mediterranean distribution, that mainly occurs in the central-eastern Mediterranean (Southern Apennine Peninsula) and the Balkans.Finally, a part of the shrub vegetation dominated by Paliurus spina-christi is referred to the class Quercetea ilicis, the order Pistacio lentisci-Rhamnetalia alaterni, the alliance Oleo sylvestris-Ceratonion siliquae and the suballiance Oleo sylvestris- Paliurenion spinae-christi that refers to thermophilous shrub communities that require high edaphic humidity.
