1, 10, 100, how many floristic databases are there in Italy?

The Group for Floristics of the Italian Botanical Society (SBI) prepared a questionnaire to be distributed among all those concerned. On the whole about three dozens feedbacks were collected and analysed.

Osservazioni sulle strategie riproduttive dei taxa appartenenti al gruppo di Limonium articulatum (Plumbaginaceae)

Limonium articulatum (Plumbaginaceae) e le specie affini costituiscono un gruppo tassonomico riconosciuto da diversi autori che si rinviene lungo le coste della Corsica, Sardegna e dell’Arcipelago Toscano. In concomitanza con indagini morfometriche, sono state condotte osservazioni sulla biologia riproduttiva di queste specie su materiale d’erbario. Nelle specie a più ampia distribuzione, L. articulatum e L. contortirameum, si sono osservate solo combinazioni autoincompatibili. Lo stesso in L. caprarie, L. corsicum, L. strictissimum e L. tarcoense. In L. coralliforme, L. dolcheri, L. florentinum, L. tibulatium e L. ursanum sono state osservate combinazioni autofertili. Non si sono verificat…

An updated checklist of the vascular flora alien to Italy

An 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 Italy. …

The species-specific monitoring protocols for plant species of Community interest in Italy

The results of a project for the identification of species-specific monitoring protocols for the Italian plant species protected under the Habitats Directive (Annexes II/IV/V) are presented. The project led to the development of 118 monitoring factsheets, providing an operational guidance for 107 vascular taxa, 10 bryophytes and 1 lichen taxon. Each factsheet includes information on the species (distribution, biology, ecology, conservation status, threats, etc.) and the description of field methodologies for the detection of the two main reporting parameters, i.e. population size and habitat quality. Practical information to plan field activities are also given. Protocols were designed to a…

Ellenberg Indicator Values for the vascular flora alien to Italy

Studies to date about plants alien to Italy have had limited focus on the ecology of this component of the flora. Ellenberg's indicator values are a useful tool to delineate the relationship between plants and environment, recognizing for each species a functional role as biological indicator; these values have been proposed for estimating the influence of the main environmental factors in determining flora and vegetation changes on a specific surface area. This contribution includes a list of 1206 taxa of plants naturalized in at least one administrative region or casual in at least three regions of Italy. In addition, some methodological considerations on the attribution and use of Ellenb…

An updated checklist of the vascular flora native to Italy
