Phytosociological Nomenclature

The paper describes the study of steppe vegetation in the Samara Region. It contains results of the steppe communities field study conducted in 2014-2015 in the vicinity of Togliatti (Samara Region). Geobotanical relevs were made on standard sites for steppe vegetation. Projective covering of plant species in field conditions was estimated as a percentage and then converted to scores using B.M. Mirkins scale. The relevs are placed in the geobotanical database Vegetation of the Volga and Ural Basins and processed using the computer program JUICE. Bioindication studies were conducted using the IBIS program. As a result of the syntaxonomic analysis carried out using the floral approach to the classification of vegetation by J. Braun-Blanquet, 2 new associations and 6 new subassociations were identified. Their names are given in accordance with the International Code of Phytosociological Nomenclature. Their position in the system of higher syntaxons of Europe is established, nomenclature types, diagnostic types are given, composition and structure, ecology and distribution of communities are characterized as well as the results of processing according to the scales by L.G. Ramensky. The communities of all established syntaxons are recommended for inclusion in the 2nd edition of the Green Book of the Samara Region.

Phytosociological Nomenclature

The article presents the typification and correction of the syntaxa of grass vegetation, established at different times for the Southern Nechernozemye of Russia. 3 associations and 5 subassociations are validated according to the requirements of the International Code of Phytosociological Nomenclature (Theurillat et al., 2021). The description of syntaxa is given according to the plan: name, synonyms, nomenclature type (holotype or lectotype), diagnostic species (their single blocks were used without dividing into characteristic, differential and constant), definition (verbal diagnosis). The belonging of associations and subassociations to the highest classification units is indicated in accordance with the modern hierarchical system of floristic classification of vegetation in Europe (Mucina et al., 2016). All of these units belong to the group of Intrazonal boreo-temperate grasslands and heath.

Phytosociological Nomenclature

Abstract This paper comments on nomenclature of the name Piceion excelsae of Pawłowski et al. (1928), which should be preferably referred using the form “Piceion excelsae Pawłowski ex Pawłowski et al. 1928”. In the author’s opinion, the definition of Recommendation 46D in the current International Code of Phytosociological Nomenclature (author citations with “ex”) needs to be revised to define alternatively the difference in contrast to Recommendation 46C (author citations with “in”): to highlight the difference at the place and time of the valid publication of the name handled. The equally aged name “Fagetalia sylvaticae Pawłowski ex Pawłowski et al. 1928” is invalidly published. The oldest validly published homonym found should be ascribed to Walas (1933).

Steppe Communities

Classification of the petrophytic steppe communities occurring on unique geomorphological formations of the Southern Urals (Bashkortostan Republik) — palaeoreefs (”shikhans“) have been performed. The plant communities were classified and included into two new associations (Minuartiо krascheninnikovii―Festucetum pseudovinae и Trinio muricatae―Centauretum sibiricae). Ecological, geographical, floristic and phytocoenotic characteristics of the syntaxa are discussed.

This paper explains how to apply for conservation or rejection of names of syntaxa according to the International Code of Phytosociological Nomenclature. First, authors have to submit a written proposal with all relevant details to be published in the Section “Phytosociological Nomenclature” of Phytocoenologia after formal editing. Then, from time to time, the Committee for Changes and Conservation of Names (CCCN) of the Working Group for Phytosociological Nomenclature (GPN) will evaluate the published proposals and make recommendations to accept or reject them. Finally, the GPN Assembly will vote on these recommendations and publish the decision.

Phytosociological Nomenclature

We present a detailed nomenclatural analysis of the class names Carpino-Fagetea, Querco-Fagetea, Quercetea robori-sessiliflorae, Quercetea ilicis and Vaccinio-Piceetea. The current literature presents contradictory opinions about the legitimacy and correct author citation of these names, often motivated by deviating interpretations of the International Code of Phytosociological Nomenclature. This primarily concerns the provisions of Articles 2b, 3j, 3m and 35 which can be interpreted in quite different ways, leading to divergent conclusions on the validity and legitimacy of a name. Thus, the problems discussed in this paper are of general relevance for phytosociological nomenclature, highlighting the need for amendments and clarifications to be implemented in the next edition of the Code. Moreover, we suggest establishing a formal procedure to request a binding decision on specific cases to stabilise the interpretation of the Code.

The aim of the work is to revise the prodrome and diagnostic species of the classes of natural dry grassland and phrygana vegetation of the Southern Crimea based on own field studies and modern literature data. Methods. The work is based on the Braun-Blanquet approach to classification of vegetation communities. Higher syntaxonomy units and lists of diagnostic species are given in accordance with “Vegetation of Europe ...” (EuroVegChecklist), nomenclature of syntaxon according to the requirements of the “International Code of Phytosociological Nomenclature”, nomenclature of taxon according to the Catalogue of Life and Euro + Med PlantBase international databases. Results. A preliminary version of the prodrome of natural dry grassland and phrygana vegetation of the Southern Crimea has been compiled. It was established that this vegetation type includes communities of 12 classes: Sedo-Scleranthetea , Trifolio-Geranietea sanguinei , Festuco-Brometea , Festuco-Puccinellietea , Kalidietea foliati , Ononido-Rosmarinetea , Cisto-Lavanduletea stoechadis , Helianthemetea guttati , Stipo-Trachynietea distachyae , Saginetea maritimae , Asplenietea trichomanis , Drypidetea spinosae. There are 14 orders, 14 alliances and 30 associations, three of which need to be validated. The classes of rock and scree vegetation ( Asplenietea trichomanis , Drypidetea spinosae ) are described in most detail. For most classes, a significant part of the classification units has not yet been established. Conclusion. The preliminary prodrome of the natural dry grassland and phrygana vegetation of the Southern Crimea includes 12 classes, 14 orders, 14 alliances and 30 associations. A great part of syntaxa has not yet been established. The composition of the diagnostic species indicates a significant floristic proximity of the classes Sedo-Scleranthetea - Helianthemetea guttati - Stipo-Trachynietea distachyae , Festuco-Puccinellietea - Kalidietea foliati , Ononido-Rosmarinetea - Cisto-Lavanduletea stoechadis .

To comply with the International Code of Phytosociological Nomenclature (ICPN), we validate the names Saturejo spinosae-Scutellarietalia hirtae, Arenarion creticae, Verbascion spinosi and Lomelosio sphacioticae-Centranthetum sieberi. Two divergent interpretations of Article 3i about the point at issue in the validation of the first three names are discussed.

Classification of steppe communities of the Western Altai piedmonts is presented according to the Braun-Blanquet approach. The most part of steppes refer to the order Helictotricho-Stipetalia. New dry steppe ass. Astragalo stenoceratis—Stipetum lessingianae is des­cribed. Zonal true steppes (associations Artemisio austriacae—Stipetum capillatae, Artemisio austriacae—Stipetum zalesskii) and their petrophyte variants (asso­ciations Gypsophilo patrinii—Festucetum valesiacae, Allio rubentis—Caricetum humilis, Eritrichio altaicae—Stipetum korshinskyi) are characterized. Three asso­ciations of meadow steppes (Carici humilis—Stipetum zalesskii, Carici pediformis—Spiraetum trilobatae, Potentillo chrysanthae—Dactylidetum glomeratae) refer to the order Stipetalia sibiricae. Changes in plants communities along the humidity gradient are analysed.
