Morphology and nomenclature are essential issues of botany, in which both extant and fossil plant taxa follow the same nomenclature code. Devonian (419.2–358.9 Ma) herbaceous lycopsid Barsassia, one of the earliest coal-forming plants in geological history, possesses a characteristic, easily recognized, step-like stem and has been thought to be an index fossil for dating and correlating the Middle Devonian strata, especially those in the paleoblocks of Siberia, Kazakhstan, Xinjiang, and North China. Here, we systematically study the Devonian lycopsid Barsassia in terms of its morphology and nomenclature, based on the new materials from the Middle Devonian Hujiersite Formation of West Junggar, Xinjiang, China, and the International Code of Nomenclature for algae, fungi, and plants (Shenzhen Code). Barsassia ornata is determined as the type species of the genus, and a neotype is designated for that name. Barsassia ornata consists of fan- or rectangular-shaped leaves with awl-shaped or finger-like distal tips. Its leaves are pseudo-whorls and imbricately arranged on the stem surface forming distinct step-like structure.

The recent proposals to conserve or reject dinoflagellate names are commented. The Nomenclatural Committee for Algae (NCA) recommended to conserve Scrippsiella against Heteraulacus and Goniodoma (proposal #2382). The synonymy of Peridinium acuminatum and Glenodinium trochoideum is highly questionable, and one Steins illustration of Goniodoma acuminatum as type will solve the doubts. An alternative genus and family name for the gonyaulacoid taxa formerly classified in Goniodoma is not provided, and Scrippsiella is a junior synonym of Duboscquodinium. The NCA confirmed Amphidoma acuminata as type species against A. nucula (2577). Stein established Amphidoma nucula as the representative species of the genus, and the poor-defined A. acuminata is associated with higher nomenclatural instability because it is probably a Centrodinium species. The NCA recommended Heterocapsa steinii as type of Heterocapsa (2607). That species name is a junior synonym of Properidinium heterocapsum and Peridinium monas. That taxon and allied species should be placed in Cachonina because Stein proposed Heterocapsa for three species of the Kryptoperidiniaceae. The proposal to conserve Alexandrium against Blepharocysta (2686) is based on that Peridinium splendor-maris is a senior synonym of Alexandrium balechii, currently classified in Gessnerium. Peridinium splendor-maris is a collective name that includes undefined organisms, and no description or illustration corresponded to Alexandrium or Gessnerium. The NCA reported that Alexandrium catenella and A. fundyensis are synonyms, without comments on A. pacificum (2302). The consequence is that one of the five species of that group has not name. Naming taxa should follow the principle of priority and the article 7.3 of the International Code of Nomenclature for algae, fungi, and plants, and rejection or conservation of names should be exceptional. Based on a supposed nomenclatural stability, the NCA is creating arbitrariness and instability in naming dinoflagellate taxa based on questionable taxonomical interpretations.

A recent review of the nomenclatural history of Rhodococcus equi and its heterotypic synonyms reveals a situation in which the strict application of the Rules of the International Code of Nomenclature of Prokaryotes have resulted in the renaming of this known zoonotic pathogen, which may be reasonably viewed as a perilous name. This situation can be remedied only by the Judicial Commission rendering an opinion to conserve the name Rhodococcus equi and to reject its earlier heterotypic synonym, Corynebacterium hoagii .

Abstract Valid publication of new names of fossil plant taxa published since 1 January 1996 requires a diagnosis or description in English, besides other requirements included in the International Code of Nomenclature for algae, fungi, and plants (Melbourne Code) adopted by the Eighteenth International Botanical Congress, Melbourne, Australia, July 2011 (McNeill et al. 2012). In order to validate names published from the late Eocene flora of the Staré Sedlo Formation, North Bohemia, diagnosed only in German (Knobloch et al. 1996), English translations are provided, including references to the type material and further relevant information.

The creation of the International Fossil Plant Names Index (IFPNI, 2014 onwards) with the aim of listing of all fossil plant species reveals a few new cases of homonymy between fossil and extant species. In the present paper there are proposed two new combinations in Hemitrapa Miki (1941: 289) and four replacing names for later homonyms of Trapa Linnaeus (1753: 120) that are illegitimate (Art. 53.1 of the International Code of Nomenclature for Algae, Fungi and Plants—ICN, McNeill et al., 2012).

According to Rule 37a of the International Code of Nomenclature of Prokaryotes, the name of a taxon must be changed if the nomenclatural type of the taxon is excluded. Recently, in a transfer of actinobacterial species, three species – Friedmanniella endophytica Tuo et al. 2016, Lysinimicrobium sediminis Hamada et al. 2017 and Lechevalieria rhizosphaerae Zhao et al. 2017 – were not transferred with their type species. Therefore, to resolve these nomenclatural issues, Microlunatus kandeliicorticis nom. nov., Demequina sediminis comb. nov. and Lentzea rhizosphaerae comb. nov. are proposed, respectively.

The Judicial Commission affirms that, according to the Rules of the International Code of Nomenclature of Bacteria (including changes made to the wording), the combination Agrobacterium radiobacter (Beijerinck and van Delden 1902) Conn 1942 has priority over the combination Agrobacterium tumefaciens (Smith and Townsend 1907) Conn 1942 when the two are treated as members of the same species based on the principle of priority as applied to the corresponding specific epithets. The type species of the genus is Agrobacterium tumefaciens (Smith and Townsend 1907) Conn 1942, even if treated as a later heterotypic synonym of Agrobacterium radiobacter (Beijerinck and van Delden 1902) Conn 1942. Agrobacterium tumefaciens (Smith and Townsend 1907) Conn 1942 is typified by the strain defined on the Approved Lists of Bacterial Names and by strains known to be derived from the nomenclatural type.

ABSTRACT A freshwater dwelling, tapering, heterocytous cyanobacterium (strain V13) was isolated from an oligotrophic pond in the Shrirampur taluka, Ahmednagar district of Maharashtra in India. Initial morphological examination indicated that strain V13 belonged to the genus Calothrix. Subsequent molecular and phylogenetic assessment based on 16S rRNA gene, led us to describe the freshwater/terrestrial clade of Calothrix strains without terminal hairs as a new genus Dulcicalothrix gen. nov., with the type species Dulcicalothrix necridiiformans sp. nov. (Strain V13) on the basis of the necridia forming ability of the strain. Also, the 16S-23S ITS secondary structure analysis clearly differentiated strain V13 from the other members of the clade. Past studies and the current state of knowledge makes it imperative to separate the groups Calothrix (marine/freshwater Calothrix), Macrochaete and Dulcicalothrix (freshwater/terrestrial Calothrix) into separate genera in accordance with the International Code of Nomenclature for Algae, Fungi and Plants. Robust phylogenetic evidence and previous reports strongly support the re-erection of the family Calotrichaceae distinct from the existing family Rivulariaceae.

Based on the high phylogenetic relatedness of Auricoccus indicus Prakash et al. 2017 and Abyssicoccus albus Jiang et al. 2016, it is proposed to unite them with retaining the latter name as having nomenclatural priority. As the result of the species unification, the genus Auricoccus name is proposed to consider as illegitimate in the boundaries determined by Rule 51a of the International Code of Nomenclature of Prokaryotes.
