Typification of seven names in the genus Antirrhinum (tribe Antirrhineae, Plantaginaceae)

The typification of seven names in the genus Antirrhinum (tribe Antirrhineae, Plantaginaceae): A. charidemi, A. latifolium, A. molle var. mollissimum, A. molle var. marianum, A. sempervirens, A. siculum, and A. valentinum is discussed. The designation of the nomenclatural types is based on the consultation of original material and the literature cited in the respective protologues. The names are lectotypified using specimens from BC, C, MA, and an illustration of Boccone published in 1697. An epitype is also designated for A. latifolium due to ambiguity in the interpretation of the lectotype. The name A. siculum is neotypified from a specimen preserved at VAL, and a second-step lectotypification is applied for the names A. sempervirens and A. valentinum. Finally, a comment on the nomenclatural type of A. cirrhigerum is reported.

On the nomenclatural type of Sohmaea barbaticaulis (Fabaceae)

The genus Sohmaea H.Ohashi & K.Ohashi (2018: 159) is characterized by predominantly linear loments with narrowly oblong-elliptic articles and comprises eight species, distributed in India through SE Asia to China and Taiwan (Ohashi & Ohashi 2018, Ohashi et al. 2018). The name Uraria barbata Lace (1915: 397) was described based on several gatherings from Myanmar. The proposed name U. barbata Lace was preoccupied for U. barbata (Linnaeus 1759: 1170) Desvaux (1826: 309) and thus, U. barbata Lace is a later homonym of the U. barbata (Linnaeus) Desvaux. Therefore, Iokawa et al. (2004: 226) proposed a replacement name U. barbaticaulis for U. barbata Lace. Later, Ohashi et al. (2018: 305) transferred the name U. barbaticaulis to Sohmaea barbaticaulis (Iokawa, T.Nemoto, J.Murata & H.Ohashi) H.Ohashi & K.Ohashi based on the phylogenetic study. The species is characterized by stems barbate, leaves dimorphic with 1-foliolate leaves in the upper portion and pinnately 3-foliolate leaves in the lower portion or 1-foliolate leaves throughout, leaflets large ovate, inflorescences axillary or terminal, pseudoracemes, fasciculate, (1 or) 2–4 per axil, flowers in clusters of 3–12 per node, loments plicate, hooked hairy (Iokawa et al. 2004, Ohashi et al. 2018, Tokaew et al. 2020). The species was earlier thought to be endemic to Myanmar until its new record from Thailand in 2020 (Lace 1915, De Haas et al. 1980, Kumar & Sane 2003, Iokawa et al. 2004, Tokaew et al. 2020), but being a rare species it is worthy of in situ monitoring for its conservation (Maxted et al. 2001, Marod & Kutintara 2012, Kawada et al. 2020, Murray et al. 2020, Perrino & Perrino 2020).

Opinions 100, 101 and 102

The International Committee on Systematics of Prokaryotes has formally made final decisions, taking into account the conclusions of the Judicial Commission, on three pending Requests for an Opinion, thereby allowing the corresponding Opinions to be issued. According to Opinion 100, the request for the recognition of strain A1-86 (=DSM 17629=NCIMB 14373) as the neotype strain of Eubacterium rectale (Hauduroy et al. 1937) Prévot 1938 (Approved Lists 1980) is denied, ruling that a neotype does not need to be designated for E. rectale because strain VPI 0990 (=ATCC 33656=CIP 105953) is considered to be a duplicate isolate of the same strain as VPI 0989 (=ATCC 25578) and may serve as its nomenclatural type. Opinion 101 approves the request that strain ATCC 25946 (=DSM 14877) serves as the type strain of Melittangium lichenicola instead of strain ATCC 25944, formally correcting the Approved Lists of Bacterial Names. Opinion 102 concludes that strain Cc m8 (=DSM 14697=CIP 109128=JCM 12621) is an established neotype strain for the species Myxococcus macrosporus , replacing the designated type strain Windsor M271, and that strain Mx s8 (=DSM 14675=JCM 12634) is an established neotype strain for the species Myxococcus stipitatus , replacing the designated type strain Windsor M78, with some additional considerations about the nature of the type material replaced and about the name Corallococcus ( Myxococcus ) macrosporus.

Reclassification of Friedmanniella endophytica, Lysinimicrobium sediminis and Lechevalieria rhizosphaerae as Microlunatus kandeliicorticis nom. nov., Demequina sediminis comb. nov. and Lentzea rhizosphaerae comb. nov., respectively

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 Nomenclatural Type of the Critically Endangered Species Chassalia boryana (Rubiaceae, Palicoureeae) Endemic to the Island of Mauritius

The lectotype of the Mascarene endemic Chassalia boryana DC. (Rubiaceae) is designated in this paper from among the most suitable original material.

Validation of the name Festuca ×polovina (Poaceae)

A natural hybridization in grasses (Poaceae) frequently occurs in the area where the distribution ranges of parental species overlap (e.g. Smith 1942, Tzvelev 1976, Soltis & Soltis 2009, Nobis 2013, Nobis et al. 2017, Wölk & Röser 2017). Such phenomenon can be observed also in the genus Festuca Linnaeus (1753: 73) between Festuca ovina Linnaeus (1753: 73) and Festuca polesica Zapałowicz (1904: 303) that distribution ranges overlap. The hybrid individuals are morphologically intermediate between those of the parental species and can be easily distinguished by leaf anatomy (Bednarska 2009). In 2009, the first author of the present paper described this hybrid as a nothospecies Festuca ×polovina Bednarska (2009: 32), providing a protologue in Latin with a detailed description of the taxon, indication of diagnostic characters, and a list of herbaria where the holotype and isotypes are stored. However, no direct citation of a particular herbarium specimen was provided for the nomenclatural type as required by Art. 40 of the ICN (McNeill et al. 2012), and hence the name F. ×polovina was not validly published.

Reinterpretation of the nomenclatural type of Archimedea pyramidalis (Balanophoraceae) with new combination to Lophophytum

We present the reinterpretation of the nomenclatural type of Archimedea pyramidalis (Balanophoraceae), resulting in the synonymization of Lophophytum leandrii. It is also designated a lectotype and an epitype. Additionally, the new combination Lophophytum pyramidale is proposed.

Nomenclatural remarks to the classification of plant communities along post-fire succession

This paper contains the original diagnoses of new syntaxa and typifications of existing names of syntaxa from paper “Classification of plant communities along post-fire succession in Pinus brutia stands in southern Antalya (Turkey)” that was published in Turkish Journal of Botany. As journal has only on-line version according to ICPN descriptions are not valid. We described syntaxa: Eryngio falcati-Securigerion securidacae all. nova, Ajugo chiae-Lactucetum serriolae ass. nova, Phlomido grandiflorae-Cistetum salvifolii ass. nova, and Arbuto andrachnes- Quercetum cocciferae ass. nova and selected nomenclatural type for Querco- Phillyreetum mediae Barbero & Quézel 1976.
