Although the Botanic Garden of the University of Pavia is the most ancient botanic garden in Lombardia, no research about its curators and gardeners has been carried on so far. After consult- ing miscellaneous literature sources and archive documents, and conducting interviews with the still living witnesses of the recent past, the lists of all the...

Invasive alien species are among the main global drivers of biodiversity loss posing major challenges to nature conservation and to managers of protected areas. The present study applied a methodological framework that combined invasive Species Distribution Models, based on propagule pressure, abiotic and biotic factors for 14 invasive alien plant...

Identifying areas susceptible to invasion by an alien species is a strategy of prevention. We used national herbaria and global databases to assess the invasion trends of the two aquatic invasive species Ludwigia hexapetala and Ludwigia peploides subsp. montevidensis in Italy. We defined the invasion status with invasions curves and predicted poten...

Ancient cultivars of apple (Malus domestica) and pear (Pyrus communis subsp. communis) at the Botanical Garden of Pavia, with notes on identification, history and phytopathology.

We analysed the invasion history of two North American macrophytes (Elodea canadensis and E. nuttallii) in Italy, through an accurate census of all available herbarium and field records, dating between 1850 and 2019, and a rich literature collection describing the initial introduction and naturalisation phase that supports the results obtained by t...

Popillia japonica at the Botanical Garden of the University of Pavia in 2021 and 2022.

Northern Italy is an area particularly suitable for the cultivation of different crops. It used to be characterized by a high agrobiodiversity. However, it is estimated that over the last decades, this area experienced a genetic erosion of more than 90%, resulting in the loss of many traditional plant genetic resources (PGR). Nevertheless, recent s...

A new locality of Sternbergia colchiciflora from Latium (Capranica Prenestina, Monte Cerella) is reported.

History and identification of the grapevine cultivars (Vitis) cultivated in Oltrepò Pavese (northern Italy).

As part of the Central European Floristic Cartography (CFCE) project, northern Italy historically appears as one of the most backward areas. This work presents the summary data of the projects that arose spontaneously and operate directly according to CFCE standards or attributable to them. In total, over 6.000.000 data are stored. The situation ha...

"The Forbidden Vineyard", a new collection of American and hybridogen grapes (Vitis) of American parentage, ate the Botanic Garden of the University of Pavia.

Lycopus is a widespread herbaceous plant, currently part of European flora. Fossil remains of fruits (nutlets or mericarps) attributed to this genus are frequently found in European archaeological and palaeontological sites, being easily preserved in sedimentary deposits. In a worldwide context, the oldest fossils are from the early Oligocene (ca....

Northern Italy is an area particularly suitable for the cultivation of different crops. It used to be characterized by a high agrobiodiversity. However, it is estimated that over the last decades, this area experienced a genetic erosion of more than 95%, resulting in the loss of many traditional plant genetic resources (PGR). Nevertheless, recent s...

Some taxonomically critical and poorly known taxa from the order Caryophyllales are discussed. Both molecular and morphological data suggest that the chorologically distant populations of Tribulocarpus dimorphanthus in Namibia and East Africa are not uniform. Consequently, a new combination for Tetragonia somalensis, previously described from East...

Ethnobotanical surveys across Italy, aiming to compile an inventory of the Italian traditional popcorns, their uses and their history, led to acquire, between 2017 and 2019, 15 seed collections from six different Italian regions, besides 26 oral testimonies from nine regions. These data evidence the relict status of popcorns in Italy, formerly more...

Identifying crop genetic resources represent an important aspect of agricultural biodiversity conservation. However, conservation of landraces is challenging because they often cannot be properly identified, or have already suffered from genetic erosion, or have disappeared. Identification of landraces can be obtained using molecular markers or dis...

Crop landraces are fundamental resources to increase the eroded genepool of modern crops in order to adapt agriculture to future challenges; plus, they are of immeasurable heritage and cultural value. Between the 1940s and the 1960s open-pollinated varieties (OPVs) of flint and semi-flint maize in Europe were almost completely replaced by high-yiel...

Ex situ conservation of plant germplasm, especially seed banking, is a favourable and widely used method for the conservation of plant genetic resources (PGR). The long-term conservation of these resources is fundamental for food security and plant breeding in order to stem the losses in agrobiodiversity and to meet the global challenges that agric...

In the original publication of this article, some letters within the caption of Fig. 1 were misplaced. The three illustrated accessions are represented in the composite figure by two images (fruits and foliage), each one identified by means of letters. In the original caption, only one letter, instead of two, is indicated for each accession. The co...

Alien grape (Vitis, Vitaceae) species and recently described hybrids are recognised as major environmental weeds in southern Europe, based on their tendency to spread into natural and semi-natural habitats, often behaving as invasive species. Despite a high number of agronomic, genetic and phytopathological studies on Vitis cultivars, regeneration...

Among these plants, 6 are invasive, 49 are naturalized and 28 are casual. With respect to previous available data, our field investigations resulted in the addi...

In the course of the systematic revision of the aggregate of Festuca circummediterranea Patzke in Gutermann et al. (1974: 261), in progress by the authors, a nomenclature issue concerning the validity of the combination “Festuca marginata subsp. gallica” proposed by Breistroffer (1966: 79) and its type emerged, which we aimed to resolve in the pres...
