Typification of the myxomycete taxa described by the Listers and preserved at the Natural History Museum, London (BM)

This paper describes a revision and typification of the slime mould or myxomycete taxa proposed by the Lister family, according to current nomenclatural and taxonomic criteria. It is based on the collections in the BM fungarium housed at the Natural History Museum, London, formerly called the British Museum (Natural History). Arthur Lister, and his daughter Gulielma Lister, conducted intense research between 1887–1945 on the taxonomy and description of new species of myxomycetes. Arthur Lister published one of the first monographs of the myxomycetes in the world “A monograph of the Mycetozoa” in 1894, from collections in BM. His daughter Gulielma Lister edited and revised a second (1911) and third (1925) edition of this keystone publication. The Listers maintained a strong relationship with the Museum, and so the BM holds most of the type specimens of the taxa described by them in the three editions of the monograph, and the huge number of the scientific papers they published on myxomycetes. In almost six decades of work, the Listers described 115 new taxa, and proposed more than 100 new name combinations, but some of them are of doubtful interpretation currently, and a clarification was needed of the nomenclatural position of the described species. A search was made of type material and documents housed in the Natural History Museum such as notebooks, collections of slides or personal annotated copies of the monographs. A large quantity of information was checked with the historically important notes and illustrations of the 50 personal notebooks, and 20 other books detailing collections studied or revised by these authors. Almost all of Lister’s nomenclatural novelties lacked type indication, although in some cases a herbarium identifier was given, often referring to multiple collections, and in other cases several collections were mentioned under the description of the new taxa, so a lectotypification was done. From the 115 new taxa described by the Listers, 2 holotypes have been determined, 2 neotypes and 86 lectotypes have been designated in this publication. In 2 taxa syntypes were found but the material was too poor to lectotypify. Ten taxa remain unresolved when the pertinent material was not located. The rest were illigitimate names or doubtful taxa. All the typification information has been standardized, the geographical information updated, and BM barcodes included to facilitate future work. A brief biography of Arthur and Gulielma Lister, some historical notes, and a revision of the organization and level of conservation of their collection at BM, are included. There are also appendices with doubtful and excluded taxa, all the new combinations proposed by these authors, a list of notebooks and a complete list of publications by the Listers.

Taxonomic novelties in African Dracaena (Dracaenaceae)

In preparing the treatment of Dracaena for Flore du Gabon and Flore d’Afrique centrale, a relatively high number of taxonomic and nomenclatural novelties were discovered; these are presented here. Within Dracaena five species and one forma are described as new, D. bushii, D. haemanthoides, D. marina, D. wakaensis, D. waltersiae and D. laxissima forma aureilicia. Each new species is provided with a full description and taxonomic notes. Apart from that, five species are reinstated, D. braunii, D. nitens, D. perrottetii, D. tholloniana and D. usambarensis. A further 23 names are treated here as a synonym for the first time: D. bequaertii, D. buettneri, D. cuspidibracteata, D. densifolia, D. gabonica, D. gazensis, D. ledermannii, D. letestui, D. litoralis, D. longipetiolata, D. monostachya var. angolensis, D. oddonii, D. perrottetii var. minor, D. poggei, D. pseudoreflexa, D. reflexa var. buchneri, D. rubroaurantiaca, D. soyauxiana, D. talbotii, D. tessmannii, D. usambarensis var. longifolia, D. vanderystii and Pleomele heudelotii, while for four names a neotype and for 14 names a lectotype has been designated. Distribution maps are provided for a total of 23 species. An index of taxon names is included.

Validation of five diatom novelties published in “Freshwater Benthic Diatoms of Central Europe” and taxonomic treatment of the neglected species Tryblionella hantzschiana

In July 2017, Lange-Bertalot et al. (2017) published a revised and translated version of Hofmann et al. (2013)’s book on freshwater benthic diatoms of Central Europe. The revised edition includes a few nomenclatural novelties which neither conform to the Melbourne Code (McNeill et al. 2012) nor to the upcoming Shenzhen Code (see Turland et al. 2017). The treatment of Tryblionella gracilis W.Sm. and T. hantzschiana Grunow shows how nomenclatural and taxonomic data can sometimes be confusing. This paper validates five names invalidly published in Lange-Bertalot et al. (2017) whilst the valid but previously neglected name T. hantzschiana is proposed to replace Tryblionella tryblio Cantonati et Lange-Bert., nom. inval. The registration numbers refer to PhycoBank (Kusber et al. 2017) a registration system on algae (Barkworth et al. 2016) which recently went online.

The fossil Osmundales (Royal Ferns)-a phylogenetic network analysis, revised taxonomy, and evolutionary classification of anatomically preserved trunks and rhizomes.

The Osmundales (Royal Fern order) originated in the late Paleozoic and is the most ancient surviving lineage of leptosporangiate ferns. In contrast to its low diversity today (less than 20 species in six genera), it has the richest fossil record of any extant group of ferns. The structurally preserved trunks and rhizomes alone are referable to more than 100 fossil species that are classified in up to 20 genera, four subfamilies, and two families. This diverse fossil record constitutes an exceptional source of information on the evolutionary history of the group from the Permian to the present. However, inconsistent terminology, varying formats of description, and the general lack of a uniform taxonomic concept renders this wealth of information poorly accessible. To this end, we provide a comprehensive review of the diversity of structural features of osmundalean axes under a standardized, descriptive terminology. A novel morphological character matrix with 45 anatomical characters scored for 15 extant species and for 114 fossil operational units (species or specimens) is analysed using networks in order to establish systematic relationships among fossil and extant Osmundales rooted in axis anatomy. The results lead us to propose an evolutionary classification for fossil Osmundales and a revised, standardized taxonomy for all taxa down to the rank of (sub)genus. We introduce several nomenclatural novelties: (1) a new subfamily Itopsidemoideae (Guaireaceae) is established to contain Itopsidema, Donwelliacaulis, and Tiania; (2) the thamnopteroid genera Zalesskya, Iegosigopteris, and Petcheropteris are all considered synonymous with Thamnopteris; (3) 12 species of Millerocaulis and Ashicaulis are assigned to modern genera (tribe Osmundeae); (4) the hitherto enigmatic Aurealcaulis is identified as an extinct subgenus of Plenasium; and (5) the poorly known Osmundites tuhajkulensis is assigned to Millerocaulis. In addition, we consider Millerocaulis stipabonettiorum a possible member of Palaeosmunda and Millerocaulis estipularis as probably constituting the earliest representative of the (Todea-)Leptopteris lineage (subtribe Todeinae) of modern Osmundoideae.

Abstract Van der Werff, H. (2017). The genera of Lauraceae in Madagascar with nomenclatural novelties in Cryptocarya. Candollea 72 : 323–328. In English, English and French abstracts. Two identification keys to the genera of Lauraceae in Madagascar based on or fruiting specimens are provided. For each genus diagnostic characters, estimates of species numbers, recent literature and additional notes are included. Eight species of Ravensara Sonn. are transferred to Cryptocarya R.

Nomenclatural novelties and notes in Penstemon (Plantaginaceae).

Seven nomenclatural novelties in Penstemon (Plantaginaceae) are proposed for taxa that will be included in the forthcoming treatment of the genus in the Flora of North America North of Mexico series. Three additional novelties are made for Mexican taxa outside the flora area. Penstemon xylus A. Nelson is determined to be the correct name for the species heretofore called P. tusharensis N. Holmgren.
