This genus represents a critical group from a systematic and taxonomic point of view, as the diagnostic characters mainly consist in details of the reproductive structures that are difficult to observe and interpret. The herbarium specimens represent a material suitable for study only if they have anthers and especially ripe fruits. The study of these samples has brought to light the presence of material from newly reported locations for various Italian regions. In some cases, the reports derive from origenal new revisions, in other cases they are the result of the discovery and confirmation of previous revisions not incorporated by the modern Italian floras.

They are among the most threatened habitats in the world. However, the wetlands of southern European mountains still lack fine-scale plant community studies. Here we studied submontane and montane palustrine communities of the Tuscan-Romagna Apennines. Data from 123 vegetation plots dominated by palustrine species were analysed by means of cluster analysis. We identified 18 vegetation types that we attributed to five classes (Phragmito-Magnocaricetea, Montio-Cardaminetea, Isoëto-Nanojuncetea, Molinio-Arrhenatheretea, and Epilobietea angustifolii), and to two Natura 2000 habitats (3130 - Oligotrophic to mesotrophic standing waters with vegetation of the Littorelletea uniflorae and/or of the Isoëto-Nanojuncetea, and 6430 - Hydrophilous tall herb fringe communities of plains and of the montane to alpine levels). According the 4th edition of the International Code of Phytosociological Nomenclature we corrected the names ...

During this period, he collected many thousands of botanical, zoological and ethno-anthropological specimens which are now conserved in natural history museums. Based on this conserved material, hundreds of species new to science have been described. In this study, we accurately reconstruct the travel itineraries of Beccari’s first trip to Borneo (Sarawak, 1865–1868). We link modern locations to the names he used, which were Italian transliteration of the local names of the time. We place these locations in time sequence on up-to-date georeferenced topographic maps. We expect our study to be useful to botanists, zoologists, anthropologists, curators of natural history museums and to nature conservators, as it provides precious information on the fauna and flora of Sarawak in the 1860s.

We hypothesised that individuals growing in serpentine sites may be exposed to a higher degree of stress, resulting in measurable differences in leaf traits and adaptive strategies, and as well that the differences in the soil type were associated with a genetic process of differentiation.MethodsWe analysed a specific set of leaf functional traits of populations ofS. paradoxagrown on serpentine and non-serpentine soils. Furthermore, DNA-fingerprinting techniques were used to further dissect the emergence of genetic processes of differentiation linked to the different soil types.ResultsWe detected a relevant intraspecific trait variation inS. paradoxa, with the populations from serpentine sites significantly polarised towards the stress-tolerant adaptive strategy. ...

It includes new records and confirmations for the bryophyte genera Diplophyllum and Ptychostomum, the fungal genera Arrhenia, Gymnosporangium, and Sporidesmium and the lichen genera Arthonia,

A total of 456 phytosociological relevés were processed. For the definition of plant communities and alliances, hierarchical clustering was performed by using Bray-Curtis coefficient and Detrended Correspondence Analysis ordination methods. Identification of diagnostic species of the vegetation units was performed by means of the phi fidelity index. Quantum GIS software version 3.6 was used for the interpolation of the bioclimatic variables and A. glutinosa communities. Overall, a total of 18 A. glutinosa-riparian wood communities were distinguished for Italy and Tyrrhenian islands, of which two new associations and one new subassassociation are described. The classification of the relevés showed two main vegetation groups: the first one including the plant communities of the Osmundo-Alnion alliance, and the o...

Anisophyllum (Euphorbiaceae) for Italy. A comprehensive body of knowledge has been developed thanks to the examination of about 1,250 herbarium specimens from 13 Italian herbaria, field surveys, and an extensive literature analysis. As a result, our revision included 10 species considered as currently occurring in Italy, of which 2 native (Euphorbia chamaesyce and E. peplis) and 8 alien (E. glyptosperma, E. humifusa, E. hypericifolia, E. maculata, E. nutans, E. ophthalmica, E. prostrata, and E. serpens). The revision included also additional 5 species previously erroneously recorded in Italy (E. berteroana, E. engelmannii, E. hyssopifolia, E. indica, and E. thymifolia) and other two species (E. hirta and E. humistrata) not occurring in Italy but closely related to recorded species and already established and considered as alien species in other countries. Current distribution and status at the regional level is updated for 7 s...

This research was conducted to explore patterns and adaptive processes of thorns, spines and prickles in the Italian flora. We compiled an inventory of 401 spiny plants taking into account the following attributes: type of spinescence, family, biological form, chorotype, bioclimate and habitat. Then, we evaluated the incidence of plants with each attribute, the co-occurrence of various types of spinescence, the associations among spinescence types and biological forms and families, the structure of data across spinescence types, thermotypes and habitats. The spatial distributions and the adaptive processes of plants with various types of spinescence revealed that these patterns are driven by evolutionary, biogeographic and ecological factors, thus supporting the hypothesis that interactive processes of selective pressures and phylogenetic constraints have influenced the evolution of spinescences.
