Based on recent molecular work by Paudyal & al., the generic limits of the Neotropical woody genus Exostema are reassessed with a view of making them more compatible with traditional, morphology‐based generic concepts. A wide circumscription is favoured, congruent with Paudyal & al.'s “clade B” (the Exostema‐Solenandra‐Coutarea‐Hintonia group). Thu...

A peculiar habitat type found in the savannahs of Central Cuba, Villa Clara Province and characterised by the presence of a surface gravel layer of “perdigones”, an assemblage of small ferralitic concretions, upon the “mocarrero” soil prevailing in the area, is described. On sterile gravel patches, only one species grows: Elytraria serpens, a ne...

This is the thirteenth of a series of miscellaneous contributions, by various authors, where hitherto unpublished data relevant to both the Med-Checklist and the Euro+Med (or Sisyphus) projects are presented. This instalment deals with the families Amaryllidaceae (incl. Alliaceae), Apocynaceae, Caryophyllaceae, Chenopodiaceae, Compositae, Crassulac...

A new subspecies of Hypericum perfoliatum is described and named. It is endemic to some Cycladean islands (Paros, Seriphos, and Naxos). On Andros and Naxos, it forms obviously hybridogenous populations with H. perfoliatum subsp. perfoliatum, the nominal taxon that is widespread on mainland Greece. The genesis of this distributional pattern is discu...

It was our plan to present the distribution in Cuba for each taxon province by province, but so far this could be implemented only for some of the taxa: those of the families (or subfamilies) for which treatments have already been published in the Flora de la República de Cuba, plus a few for which we found specialists willing to provide the partly...

The results of a statistical biometric study of the Centaurea busambarensis complex, which represents the C. cineraria aggregate in Sicily and its offshore islets, are presented. Seventeen populations, representing all seven previously recognized taxa (four species and three additional subspecies) plus a presumed undescribed one were studied. The s...

The Melbourne Congress of 2011 authorized a Special Committeeon Registration of Algal and Plant Names (including fossils), whichwas established the following year (Wilson in Taxon 61: 878–879.2012). Its explicit mandate was “to consider what would be involved inregistering algal and plant names (including fossils), using a procedureanalogous to tha...

The Special Committee on By-laws for the Nomenclature Section was established at the XVIII International Botanical Congress (IBC) in Melbourne in 2011, with the mandate to formalize the procedures by which changes to the Code are considered and voted upon by the Nomenclature Section, and to report to the XIX IBC in Shenzhen in 2017. With the wider...

More than 15 years after the start, the Euro+Med PlantBase project (E+M), which aimed at providing a comprehensive, dynamic and permanently updated online checklist of all vascular plants for Europe and the Mediterranean countries, is now very close to full coverage. E+M is the most detailed resource on plant biodiversity in the Euro-Mediterranean...

Biographical data are presented on Friedrich Jakob Dochnahl (1820–1904), a once prominent but long forgotten German pomologist. Two among his scientific works, the “New pomological system” of 1847 and the four-volume “Secure guide in pomology” (1855–1860), being of interest for nomenclatural purposes, are presented and discussed in detail. The form...

The group of Centaurea (sect. Acrolophus) cineraria (Compositae) in Sicily includes four currently accepted species plus four taxa that have been considered, with some doubt, as subspecies of one of them (C. panormitana). In total, discounting recombinations and replacement names, 11 names (seven specific, three varietal, one of a forma), all based...

The seven species currently placed in the genus Nashia are revised, based on the near totality of the (scant) material found in the world's herbaria. A morphological analysis of, in particular, the calyx and fruit reveals the heterogeneity of that genus. As a result, Nashia is reduced to its single original species, N. inaguensis, described from Gr...

The realization that a unified Code of nomenclature applicable to all organisms was ideal emerged during a meeting of the IUBS/IUMS International Committee on Bionomenclature (ICB) held in Egham (UK) in March 1994. Later that year, the IUBS General Assembly in Paris passed a resolution urging the ICB to "expedite work towards a unified system of bi...

Cynoglossum marifolium was described and validly named in 1824, in a posthumous publication of Roxburgh. Clarke in 1885 unaccountably relegated it to the synonymy of Heliotropium marifolium Retz., where it has since remained, even though the original description forbids such placement. No original specimen is known to exist, but an original waterco...

RESUMEN Se revisan los datos de la literatura sobre la distribución de Enicostema verticillatum, el único representante del género en el Nuevo Mundo.

The typification of the Linnaean name Hieracium cerinthoides (Compositae) is discussed. Original material conserved in LINN is designated as the lectotype. An epitype is also designated here in order to avoid any ambiguity in the interpretation of the type specimen.

The name Isoetes setacea Lam. has been applied to two different species, causing nomenclatural and taxonomic confusion. Some authors have rejected it on that account, yet it is currently used in a sense that is incompatible with its type. That type represents one of two similar species, I. echinospora and I. lacustris, which still today grow togeth...

Are the rules of nomenclature really that confusing and vague? Thoughts on the Ophrys subfusca controversy. The name Ophrys subfusca, based on Ophrys lutea var. subfusca Rchb. f., was validly published in 1899 by HAUSSKNECHT, then correctly typified in 2011 by LOWE and provided by him with an epitype. By consequence it belongs (either as accepted n...

As a result of our work on the Lycopodiaceae account for the Critical Flora of Italy, a new, synonymic inventory of Italian taxa is presented, based on herbarium studies and critical re-examination of extant literature. Three genera with 8 species are accepted: Huperzia (1 species), Lycopodiella (1), and Lycopodium (6). An additional, ninth species...

An annotated synonymic inventory of Italian Selaginella taxa, a practical key for their identification and their dot distribution maps are presented, as a result of our work on the Selaginellaceae account for the Flora Critica d’Italia. The names Lycopodium helveticum L. and Selaginella denticulata var. platystachya Hieron. are typified.

A new species from Montevergine in Campania, Hieracium barrelieri, is described in detail. It is closest to H. acanthodontoides of. H. murorum var. barrelieri, an obsolete taxon described by Tenore, is also discussed, as it was partly based on the same population.

Background: An inventory is presented of all names so far validly published in Cynoglossum sensu lato and its segregate genera: Adelocaryum, Afrotysonia, Kuschakewiczia, Lindelofia, Mattiastrum, Paracaryum, Rindera, Solenanthus, Trachelanthus, and their synonyms. Names and designations that were not validly published in the cited place, and later...

Procedures are presented that were followed during the preparation of the first pteridophyte family treatments for the “Flora Critica d’Italia”: Lycopodiaceae, Isoetaceae, Selaginellaceae. The work was mainly based on the study of literature and herbarium specimens. In some cases SEM observation of spores has proved useful. Data collected from herb...

The Mediterranean Region is among the areas of the world richest in wild and cultivated taxa. Extinctions in the Mediterranean area are bound to have occurred in historical times but they are not documented. The probable and documented cases of plant extinction in specific areas within the Mediterranean are equivalent to 0.25% of total species-by-a...

Michele Lojacono Pojero (1853-1919) is among the most prolific Italian authors of plant names of his era. A list is presented of the names of 581 new Italian (almost invariably Sicilian) vas-cular plant taxa he published (303 species, 272 varieties, 6 formae), with reference to existing lectotype designations.

Two previous attempts to designate a type for Gomphia Schreb. 1789 failed. The type here designated is Ochna nitida Sw. This confirms the status of Gomphia as a taxonomic synonym of Ouratea Aubl. 1775. Ochna squarrosa L. 1762 is a legitimate name, it is lectotypified here so as to make it a nomenclatural synonym of Ochna jabotapita L. 1753, confirm...
