Taxonomic and Phylogenetic Investigations on Psoralea Acaulis (Psoraleeae: Fabaceae) With the Description of A New Genus Kartalinia
2018
Salmeri, Cristina/0000-0002-5261-590X WOS: 000454161300003 Psoralea acaulis Hoffm. is a very peculiar and taxonomically isolated species of the tribe Psoraleeae, occurring in the Caucasian territories. Currently, this tribe contains 10 distinct genera, well differentiated morphologically. Due to some morphological similarities, P. acaulis was attributed to Bituminaria Heist ex Fabr., a genus with a Mediterranean-Macaronesian distribution. However, as it has many characters, some of which are autapomorphic, it was assigned its own subgenus: Christevenia Barneby ex C. H. Stirt. In light of detailed cladistic and phylogenetic analyses, this arrangement is taxonomically questionable and rather …
Taxonomic investigations on Psoralea palaestina (Fabaceae), a critical species of Mediterranean flora
2016
Psoralea palaestina is a critical and unappreciated species described from Palestinian territories, and currently treated as synonym of P. bituminosa, nowadays known as Bituminaria bituminosa. Nomenclatural investigations allowed to ascertain that it was validly described for the first time by Bassi (1768) and not by Gouan (1773), as previously thought. Extensive taxonomic investigations revealed that this very peculiar legume is morphologically well differentiated from the other allied known species. Therefore, it has to be properly treated at specific level and transferred to the genus Bituminaria, thus proposing a new combination: Bituminaria palaestina. Based on literature, herbarium an…
Naturalistic hotspots along the Itinerarium Rosaliae (CW Sicily, Italy)
2018
The conservation, fruition and management of landscape and natural resources is one of the most important topic of the moment. Here we presented a study on naturalistic hotspots that can be found along the Itinerarium Rosaliae, a naturalistic and religious route in Sicily that crosses three natural reserves and one natural regional park connecting Mount Pellegrino with the Hermitage of Santo Stefano di Quisquina. On the whole 7 semi-natural woods, 13 monumental trees, 8 geosites, and 4 areas of high naturalistic interest were identified. This initiative can be of example for other territories where human and natural heritage can be connected for an organic network of fruition.
Charybdis glaucophylla (Asparagaceae), a new species from Sardinia
2012
Charybdis glaucophylla (Asparagaceae), a new species from Sardinia, is described and illustrated. It is a diploid species with 2n = 20 chromosomes growing along the rocky coast, sandy dunes and mountain top in the south-western part of the island. Within the genus, this species results taxonomically well isolated and differentiated due to relevant morphological and phenological features, such as the leaves wide and short, very rigid and glaucous-pruinose, as well as the very late foliation (winter). It shows only some relationships with C. pancration for the whitish bulb tunics and the diploid chromosome complement, and with C. maura and C. aphylla due to the glaucous leaves.

Environmental quality assessment of the Sicilian coast using a multi-disciplinary approach
2018
A multidisciplinary approach for the assessment of the environmental quality of the Sicilian coast is presented. This approach can be adopted for any Mediterranean coastline. The territory was divided into elementary areas and for each of them we reported the most important taxa, belonging to fauna and vascular, bryophytic and algal flora, from a biogeographic point of view in order to evaluate punctual and general levels of biodiversity conservation. The comparative analysis showed that the main circumsicilian islands and the carbonate promontories of the Tyrrhenian coast present the highest degree of biodiversity. The coastal lagoons located in the south-eastern Sicily, even though charac…
Hypericum scruglii sp. nov. (Guttiferae) from Sardinia
2010
A new species of Hypericum (Guttiferae) from Sardinia, H. scruglii, is described and illustrated. It occurs on damp soil, near springs or streams with freshwater, where it grows with numerous hygrophytes. This diploid species (2n � 16) belongs to the sect. Adenosepalum and is closely related to H. tomentosum, a species widespread in the west Mediterranean region. During field investigations in Sardinia, very peculiar populations of Hypericum L. were found occuring on damp soils and limited to calcareous substrates. These plants showed a close morphological and ecological relationship with H. tomentosum L., a species belonging to sect. Adenosepalum Spach. As emphasized by Robson (1996), the …
The endemic vascular flora of Peloritani Mountains (NE Sicily): Plant functional traits and phytogeographical relationships in the most isolated and …
2014
This study is aimed at (1) producing a complete and updated inventory of the endemic vascular flora of Peloritani Mountains, (2) defining the geographical limits of Peloritani, regarded here as a biogeographical district and (3) highlighting possible paleogeographic connections with other Mediterranean lands. The heterogeneity analysis of the endemic flora was performed by means of contingency tables, through the x 2 test. The endemic flora of this area consists of 129 specific and infraspecific taxa, of which 15 are restricted to the Peloritani Mountains. The analysis of habitats revealed that endemic taxa are most abundant on cliffs, rangelands, woods and garrigues. A large number of surv…
A new species of Anthemis sect. Hiorthia (Asteraceae) from SE Sicily
2013
A new species of Anthemis sect. Hiorthia (Asteraceae) is described from Sicily. This taxon, named A. piagnattiorum, is confined to a restricted area of the Hyblaean territory (SE Sicily), in the Natural Reserve of Cava Grande (Cassibile, Siracuse), where it takes shelter on carbonate rocky habitat and participates, with other Sicilian endemic taxa, to the composition of a termophilous chasmophytic community (Putorio calabricae–Micromerietum microphyllae).
