Taxonomy, karyology, chorology and ecology of A. pallens L., a circummediterranean species occurring in synanthropic habitats, are examined. It is closely related to A. convallarioides Grossh., a diploid species linked to natural habitats, which can be considered its probable ancestor.

Sicily, in particular, can be defined as the "core essence" of this landscape, because its strategic central position in the Mediterranean made it a crossroads of people and historical events. Results from such connection are clearly readable both in urban and rural settings, where the time sequence of human activities produced a great diversity of features and land assets. Gardens as planned places including both natural and man-made materials are good indicators of the man/land relations. As a matter of fact, gardens have the capability to give physical form to human experiences, memories, and ideas which reflect the awareness of current and past life, as well as the perception of surrounding environment and landscape. Mediterranean gardens in Sicily effectively reproduce the singular mixture of historical, social and cultural processes occurred over the time and clearly show layered signs of changing lifestyles and environmental contexts. In this respect, eastern Sicily offers an interesting case study since very different geographic layouts, bioclimatic conditions, socioeconomic and cultural background discriminate these territories from the western part of the island. Particularly, the prevailing lack of large rural estates (latifondi) and the early partitioning of lands to smallholders, as well as the emergence and spread of a rural high bourgeoisie gave rise to a significant representation of garden models, often small sized, with original design, materials, and plant collections (1). Far from providing a full check of the existing garden diversity, a representative frame can be summarized by the following types. ─ Monastic gardens, with a cloister inside and a fruit/vegetable garden outside the walls; an adjoining natural park, called silva, was often integrated part of church lands. Many of them have become public gardens after the ecclesiastical confiscations in 1866. Examples still occur in Piazza Armerina (now Giardino Garibaldi), in Catania (San Nicolò La Rena), Siracusa (Latomia of Capuchins) and Taormina (San Domenico), although deeply altered and rearranged in their plant scheme and composition (2, 3). ─ Country houses of different relevance and size, typical of the rural Mediterranean landscape; firmly rooted in the agriculture productivity, they were farm estates mostly devoted to crop production and/or livestock breeding, while the ornamental garden, next to the main dwelling, was reserved to the private recreational use of the owner's family. Examples varied from big productive complexes, old centres of rural communities, like Villa Fegotto (Chiaramonte Gulfi, RG), Nelson's Duchy (Bronte, CT), Villa Zirilli (Milazzo, ME), to minor mansions with smaller plots of land and farming incomes, well represented both in the hyblaean and etnean countryside, e.g. Villa Gisana (Modica, RG), Villa Casalotto and Villa Previtera (CT). ─ Holiday and residential villas in the suburban or rurban areas, common expression of a comfortable and wealthy lifestyle related to aristocracy and then to high middle class; gardens represented beautiful escape from the summer heat, but mainly they incorporated combinations of good social standing, reputation, influence, and honour of their owners. These are the most preserved and representative historic gardens, such as Villa Elvira del Principe Bonaccorsi (Milazzo, ME), Villa Falconara and Casa Cuseni (Taormina, ME), Villa Bellini and Villa Consoli Marano (CT), Villa Patti (Caltagirone, CT), Villa Reimann (SR), Donnafugata Castle and Villa Palmeri di Villalba (RG) (4). ─ Green promenades and tree pathwalks, born as first types of public green spaces; they were designed to provide recreational opportunities for leisure, walking and gathering of citizens, both in main and small cities, and in time were enlarged to become typical public gardens, e.g. Villa Pacini (CT), Villa Belvedere (Acireale, CT), Giardino Ibleo (RG), Villa of Palazzolo Acreide (SR). As usual, these main garden types can be further characterized following a temporal range from the 18 th to the 20 th century, and a spatial extent North-South of eastern Sicily (Valdemone and Val di Noto). Regarding the time scale, gardens in E Sicily show style changes varying from the typical Italian design, to the romantic and eclectic forms, all sharing the common Mediterranean use of fruit trees, aromatic plants and palms as main botanical collections (5). Geographic gradient, instead, results in the use of different materials (stone, clayey, terracottas, wood), decorations and handcrafts, strictly related to the landscape and local customs, as well as in the plant composition depending on specific microclimate contexts, cultural trends and exchanges of garden owners or gardeners with botanical gardens, science community and plant collectors.

Cass. ex Spach is a common Mediterranean weed producing distinctive central and peripheral dormant cypselae with a hard fruit coat, which was previously hypothesized to impose physical dormancy. Analysis of water uptake in cypselae and in naked seeds showed that it preferentially takes place at the basal end of the fruit; however, seeds within an intact pericarp do not fully imbibe when compared with naked seeds. Germination was not significantly different between the two heteromorphs, and afterripening or cold stratification did not increase germination, while warm stratification at 35/20°C, as revealed by logistic regression, resulted in a significant improvement. However, loss of viability was also rapid at these high temperatures. Central and peripheral cypselae generally showed very low germination. In both heteromorphs, faster and higher germination (60–70%) was reached only after extensive scarification of pericarp tissue, and full germination was obs...

Relevant features in its morphology, caryology and leaf anatomy emphasize the marked taxonomic isolation of this taxon and allow it to be treated as a distinct species, proposed as Allium exaltatum. It is an exaploid plant (2n=48), probably arisen out of allopolyploidy and morphologically related only to some Middle East taxa.

An anonymous pre-Linnaean herbarium among the “treasures” of the “Civica and A. Ursino Recupero” joint library of Catania (Italy)

Ursino Recupero” joint library of Catania (Italy) has been carried out. The volume examined consists of 86 unnumbered pages. It is made up of 121 specimens (currently four samples are missing), all belonging to Angiosperms. The samples are not all in good condition; however, it was possible to determine most of them (86%) up to species level. Most of the taxa are made up of alien plants (20.62%) of African and American origin. A series of concordant clues leads us to conjecture that the herbarium was produced by Antonio Bonanno (a pupil of Francesco Cupani) on the orders of the Prince of Cattolica, and/or some of his collaborators (or successors). The report of exchanges of plants with William Sherard, the particular composition of the collection and the documented knowledge of the international literature allow us to place the herbarium in the context of the intense scientific activity that took place in Sicily even after the deaths of Paolo Boccone and Cupani, two important pre-Linnaean Sicilian botanists.

The area covers the central city (Catania) and a number of smaller centers (villages) connected by territorial contiguity of close integration with regard to economic activity, environmental, vital services for social and cultural relations. The component of alien species was compared to that of native ones, considering the historical and spatial aspects, and the role and presence of the non-native plants in natural habitats. Furthermore, three cases of the new recordings of exotic species have been reported.

The study area is extended to 939 km 2 and includes 15 km of coastal habitat. Floristic data were used to analyze environmental changes. The vascular plant flora was investigated through a literature list for periods from 1889 to 1909 and from 1970 to 1990 and through an extensive survey campaign from 2010 to 2017. A total list of 927 species was acquired. Each species was associated with its own ecological and chorological information. Ellenberg's values were used as environmental indicators to assess the relationship between plant species and environmental factors.

Such volcanoes, locally called Salinelle, are phenomena that occur around Mt. Etna (Sicily, Italy) and are interpreted as the surface outflow of a hydrothermal system located below Mt. Etna, releasing sedimentary fluids (hydrocarbons and NaCl brines) along with magmatic gases (mainly CO 2 and He). To date, scarce data are available about the presence of trace elements, and no biomonitoring campaigns are reported about the cumulative effects of such emissions. In this study, concentrations of Al, As, Cd, Cr, Cu, Hg, Mn, Ni, Pb, V, and Zn were detected in the moss Bryum argenteum, in soil and water. Results showed that the trace element contribution of the Salinelle to the general pollution was significant for Al, Mn, Ni, and Zn. The comparison of trace concentrations in mosses from Salinelle and Etna showed that the mud volcanoes release a greater amount of Al and Mn, whereas similar values of Ni were found. Natural emissions of trace elements could be hazardous in human settlements, in particular, the Salinelle seem to play an important role in environmental pollution.
