An updated checklist of the vascular flora native to Italy
2018
AbstractAn updated inventory of the vascular flora alien to Italy, providing details on the occurrence at regional level, is presented. The checklist includes 1597 species, subspecies, and hybrids, distributed in 725 genera and 152 families; 2 taxa are lycophytes, 11 ferns and fern allies, 33 gymnosperms, and 1551 angiosperms. 157 taxa are archaeophytes and 1440 neophytes. The alien taxa currently established in Italy are 791 (570 naturalized and 221 invasive), while 705 taxa are casual aliens, 4 are not assessed, 7 are of unknown regional distribution, 47 have not been confirmed in recent times, 3 are considered extinct or possibly extinct in the country, and 40 are doubtfully occurring in…
Effect of Bacterial Inoculum and Fertigation Management on Nursery and Field Production of Lettuce Plants
2020
Plant growth-promoting rhizobacteria have been applied to different vegetable crops but there is still no information on the effect of bacterial biostimulant application under variable nutritional level on lettuce seedlings and their performance after transplanting in the field. This study aimed to evaluate the efficacy of a bacterial biostimulant to enhance growth and quality of lettuce seedlings fertigated with increasing nutrient rates and to assess the efficacy of these treatments on lettuce head production. Lettuce seedlings were inoculated with 1.5 g L&minus

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. Furthermore, three new combinations are proposed. Nomenclatural and distribution updates published elsewhere are provided as Suppl. material 1.
Checklist of gypsophilous vascular flora in Italy
2018
Our understanding of the richness and uniqueness of the flora growing on gypsum substrates in Italy has grown significantly since the 19th century and, even today, new plant species are still being discovered. However, the plants and plant communities, growing on gypsum substrates in Italy, are still a relatively unknown subject. The main aim of this paper was to elaborate a checklist of the Italian gypsophilous flora, to increase knowledge about this peculiar flora and for which conservation efforts need to be addressed. Through a structured group communication process of experts (application of the Delphi technique), a remarkable number of experienced Italian botanists have joined togethe…

The urban vascular flora of Palermo (Sicily, Italy)
2019
This article presents a comprehensive inventory of the urban vascular flora of the town of Palermo. The data were gathered from extensive field collections, from specimens kept in different herbaria, and publications of the last 30 years. The floristic catalogue includes all the vascular plants that occur spontaneously within the urban area. Thirteen taxa are endemic to Sicily and one of these, Clinopodium raimondoi, is exclusive to Palermo’s area. The inventory comprises 1052 taxa belonging to 119 families and 225 genera, and contains 170 taxa non-native to the Italian flora.

Lectotypification of the name Scrophularia tenuipes Coss. (Scrophulariaceae)
2019
The present contribution is part of an ongoing project for the investigation of the Algerian-Tunisian Flora (see e.g., El Mokni et al. 2014, 2015a, 2015b, 2015c; El Mokni & Iamonico 2018, El Mokni & Domina 2019). Special attention is dedicated to the endemic component of this flora and its type localities (loci classici), that are considered a rich source of biogeographical information (Brundu et al. 2015).
Poa jubata (Poaceae), a rare Balkan species, first record for the Italian flora
2019
Abstract Poa jubata A. Kern., an annual South-eastern European species, is reported for the first time from Italy. It is a therophyte linked to temporary ponds with soils flooded during the winter period. It is a very rare and enigmatic species, currently known only from a few localities of the Balkan Peninsula. Recently, it was surveyed in an Apulian wetland, near Brindisi, where it grows with several other annual hygrophytes. For its taxonomical isolation, it is included in a monospecific section, as P. sect. Jubatae. In addition to a detailed description, the chromo-some complement (2n = 14) of this species is examined for the first time and a new iconography is provided.
