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.
Taxonomy and evolution of the Convolvulus sabatius complex (Convolvulaceae)
2010
A revision of the Convolvulus sabatius complex is presented and five taxa are now recognised. Convolvulus valentinus is re-circumscribed to comprise only blue-flowered individuals. Yellow-flowered plants previously referred to this species are transferred to C. supinus where they are recognised as a distinct variety: C. supinus var. melliflorus, comb nov. Variation in intensity of flower colour, pubescence and leaf shape among blue-flowered C. valentinus is highly variable within populations and in contrast to earlier treatments, no infraspecific taxa based on these traits are recognised. Despite suggestions to the contrary, the delimitation of the cultivated ornamental C. sabatius and its …
A Nomenclatural and Taxonomic Revision of the Senecio squalidus Group (Asteraceae)
2022
Senecio squalidus (Asteraceae) currently includes nine subspecies distributed in North and Central Europe and in the Mediterranean basin. Within this taxonomic aggregate, many species have been described, but research on their nomenclatural types is incomplete. A complete nomenclatural survey of 19 names belonging to this taxonomically critical group was carried out. Fourteen lectotypes are here designated. The nomenclatural analysis, complemented by field investigations in the type localities of the taxa described in the Central Mediterranean, allowed us to accept 10 species. Accordingly, we proposed here a new name and a new missing combination at a specific level: S. aknoulensis and S. c…
Integrative Taxonomy of Armeria arenaria (Plumbaginaceae), with a Special Focus on the Putative Subspecies Endemic to the Apennines
2022
Three subspecies of Armeria arenaria are reported from Italy, two of which are considered endemic to the Apennines. The taxonomic value of these two taxa (A. arenaria subsp. marginata and A. arenaria subsp. apennina) is unclear. Moreover, the relationships between A. arenaria subsp. praecox and Northern Italian populations—currently ascribed to A. arenaria subsp. arenaria—have never been addressed. Accordingly, we used an integrated taxonomic approach, including morphometry, seed morpho–colorimetry, karyology, molecular systematics (psbA–trnH, trnQ–rps16, trnF–trnL, trnL–rpl32, and ITS region), and comparative niche analysis. According to our result…

Onomastyka literacka a onomastyka stylistyczna
2016
The paper deals with the state of research on literary/stylistic onomastics as an auxiliary science of stylistics. The typology of styles allows the inclusion of research on stylistic nomenclature within the research on text style, an author’s individual style, as well as type styles. Post-modem changes in the understanding of literariness, the interest of literary onomastics in para-literary genres, and the functioning of names in the modem media, religious and political discourse make it necessary to think about the appropriateness of further use of the term literary onomastics. The use of the original name of the field of research on names in texts would be more precise: the term stylist…
Validation of chasmophytic syntaxa of colline and montane zones in Tajikistan (Middle Asia)
2016
AbstractEight syntaxa are validated with the previous names regarded as invalidly published according to the International Code of Phytosociological Nomenclature. The validation concerns syntaxa of rock plant communities of the Campanuletalia incanescentis order reported from the Pamir Alai mountains in Tajikistan. The majority of validated syntaxa represents association level, one is an alliance. All validations are conducted due to the invalidity of tables with typus releves according to art. 1 of the Code: they were not distributed as printed matter. The validated syntaxa are as follows: Caricion koshewnikowii, Scutellarietum hissaricae, Scutellarietum schugnanicae, Scutellarietum zaprja…
