An integrated approach to the study of Hypericum occurring in Sicily
2020
An integrated approach to the study of taxa of the genus Hypericum occurring in Sicily is proposed. The results of morphological, biochemical, and molecular analyses are combined to better assess the relationships between the species investigated and test the suitability of DNA barcoding technique in the discrimination of these taxa. For the name Hypericum aegypticum subsp. webbii (Spach) N. Robson a lectotype is designated. For Hypericum triquetrifolium Turra a lectotype and a supporting epitype are designated. The presence of Hypericum perforatum L. subsp. perforatum is excluded from Sicily and the previous reports have to be referred to H. perforatum subsp. veronense (Schrank) Ces. Hyper…
Epitypification of Hagaea alsinifolia (Polyycarpon tetraphyllum subsp. Alsinifolium, Caryophyllaceae)
2018
As part of the ongoing studies on the genus Polycarpon Linnaeus (1759: 859, 881) (see e.g., Iamonico 2015a, 2015b, 2015c, Iamonico & Domina 2015), and on the Italian loci classici (see e.g., Peruzzi et al. 2015, Brundu et al. 2015, Domina et al. 2016, Di Gristina et al. 2017, Domina et al. 2017, 2018a, 2018b), we present here a note regarding Hagaea alsinifolia Bivona-Bernardi (1815: 7–8) [currently accepted (see Bartolucci et al. 2018) as Polycarpon tetraphyllum Linnaeus (1759: 881) subsp. alsinifolium (Biv.) Ball (1877: 370)].
Lectotypification of the fountain grass Cenchrus setaceus (Poaceae: Paniceae)
2015
The typification of the name Cenchrus setaceus (Forsskål) Morrone (Poaceae) is discussed, and a lectotype is designated. Cenchrus setaceus is native to northeastern Africa, and cultivated as an ornamental plant in some parts of the world. It is an invasive species in a wide range of natural habitats worldwide, competing strongly with the native flora.
Rubus aetnicus Cupani ex Weston and R. canescens DC. (Rosaceae): an analysis
2021
Beek (2016) argued that Rubus aetnicus Cupani ex Weston was the correct name of the taxon that was then called R. canescens DC., and which was previously known as R. tomentosus Borkh. Moreover, R. canescens was stated to be not identical with R. aetnicus, but rather a form of R. × collinus DC. Matzke-Hajek (2016) raised objections to both statements. Therefore, the aim of this study was to thoroughly analyse both names and support this analysis with field work at the type localities and by DNA data. Despite the correspondence at the investigated conservative DNA loci, the investigation showed that the two species are morphologically different and must be conceived as separate taxa. Accordin…
Typification of the name orobanche ebuli huter & rigo (orobanchaceae) and its taxonomic implications
2018
The present contribution is part of the ongoing work aimed at researching and identifying the original material on which the names of Orobanche Linnaeus (1753: 632) described for Europe and the Mediterranean are based (Domina et al. 2005, Domina & Stepanek 2009, Domina et al. 2013, Carlón et al. 2015). It falls within the researches promoted by the Italian Botanical Society aimed at recognizing and typifying all the taxa described from Italy and their loci classici, in order to increase their systematic knowledge and promote further studies (Domina et al. 2012, Peruzzi et al. 2015, Brundu et al. 2017). Orobanche ebuli Huter & Rigo (1907: 354), is an Italian endemic (Peruzzi et al. 2…
Lectotypification of the name Cistus stipulatus, basyonim of Helianthemum stipulatum (Cistaceae)
2015
The typification of the name Cistus stipulatus Forsskål (≡ Helianthemum stipulatum (Forsskål) Christensen) is discussed. The designation of the nomenclatural type is based on an assessment of Forsskål’s original material. The name is lectotypified selecting a specimen from the Herbarium Forsskålii in the National Herbarium Copenhagen at C.

Ergonyms of Educational and Cultural spheres in two of Baltic States cities
2020
Daugavpils (Latvia) and Narva (Estonia) are cities in the Baltic States and signifi cant cultural and economic centres of their respective countries. These cities are characterized by a minority of nationals (19.8% of residents of Daugavpils are Latvian, 4% of residents of Narva are Estonian) and a similar linguistic situation: there is a dominance of Russian in the press, television and radio, but the state language prevails in the urban language signs.The aim of the study is to analyse the linguistic and extralinguistic means used for the creation of ergonyms of educational and cultural spheres. The main criteria for the analysis are: language choice, grammatical structures, sources of pr…
Definition of the chalcogen bond (IUPAC Recommendations 2019)
2019
Abstract This recommendation proposes a definition for the term “chalcogen bond”; it is recommended the term is used to designate the specific subset of inter- and intramolecular interactions formed by chalcogen atoms wherein the Group 16 element is the electrophilic site.
Liberalism, how many divisions?
2022
Liberalism is a very broad political family which, if taken in the broadest sense, brings together authors with diverse positions whose only common point is their attachment to freedom. Therefore, to find one’s way around in this political family, it is essential to establish classification criteria. There are many possibilities: Liberals can be classified by nationality, by period, by preferred field of interest (economic liberalism, political liberalism), etc. This article proposes to classify them following two criteria, the conception of freedom on the one hand, and the utilitarian or jusnaturalist basis of the attachment to freedom on the other. These two criteria generate an operation…
