The status of Rivea bernoulliana (Convolvulaceae) is resolved.

From 2016 to 2018 a comprehensive mapping of hawkweeds (Hieracium s. str., Pilosella and Chlorocrepis) accompanied by intensive activities in collecting of herbarium specimens was carried out in the Burgenland (Austria). Additionally, records cited in literature and obtained by revision work in several European herbaria were added to our database. As a result, an annnotated list of hawkweeds species in Burgenland country is presented. It is based on almost 2900 datasets, of which nearly 2700 are documented by herbarium specimens. In additition to Chlorocrepis staticifolia the list includes 22 species of the genus Hieracium with 64 subspecies and 32 species of the genus Pilosella with five subspecies. All of them are documented by herbarium specimens. In addition, 31 subspecies from literature are cited in the text. Eight species of the genus Hieracium (H. diaphanoides, H. glaucinum, H. neostenophyllum, H. pillii, H. pseudobifidum, H. rotundatum, H. sibaricum, H. transylvanicum) and eight species of the genus Pilosella (P. acrothyrsa, P. calodon, P. erythrochrista,P. flagellaris, P. heterodoxa, P. koernickeana, P. tubulata and P. ziziana) were detected for the first time in Burgenland. Seven species, mentioned in the botanical literature (H. clusii, H. saxatile, H. schmidtii, H. subramosum, P. dubia, P. onegensis, Schlagintweitia intybacea) are classified as wrong or dubious information. The name of H. brevifolium subsp. brachysteleon is validated, the name of H. pilosellinum subsp. purbachense is lectotypified. Six new combinations are made: H. rotundatum subsp. lancifolium, H. rotundatum subsp. leptocephaloides, H. rotundatum subsp. platyrhombum, H. rotundatum subsp. pleiophyllopsis, H. rotundatum subsp. praecurrens, H. rotundatum subsp. subserratifolium.

Lectotypifications of Photinia beckii, Ph. chingiana, Ph. crassifolia, Ph. crassifolia var. denticulata (synonym of Ph. crassifolia), Ph. glomerata, Ph. serrulata var. congestiflora (synonym of Ph. glomerata), Ph. lindleyana var. yunnanensis (synonym of Ph. glomerata), Ph. mairei, Ph. serrulata var. prunifolia (synonym of Ph. prunifolia), Ph. serrulata var. obovata, Ph. stenophylla, Ph. undulata var. formosana (synonym of Ph. davidiana var. formosana), and Pyrus cavaleriei (synonym of Ph. davidiana) are designated here. The protologues of these names and the original materials are evaluated. Taxonomic notes discussing the selection or correction of type specimens are given for each name, and, when possible, known isolectotypes are also cited.

A lectotype for Carex aestivalis (Cyperaceae; sect. Hymenochlaenae), a sedge from the Appalachian Mountains, U.S.A., is designated. The authorship of the name, hitherto cited as M.A. Curtis ex A. Gray, is revised to show that M.A. Curtis, alone, is the author of the species name and the original description.

This study presents an evaluation of the currently accepted sectional classification of the genus Anthurium Schott (Araceae) in light of a recently published molecular phylogeny for the group. In general, disagreements between these two occur because many diagnostic morphological characters used in the sectional classification turned out to be highly homoplasious within Anthurium, with multiple independent gains or losses of seemingly similar morphologies in distantly related clades. A new sectional classification of Anthurium that more accurately represents species relationships and the evolutionary history of the genus is much needed, and here we propose the first steps toward it. Results from this study suggest that out of the 18 sections and two series recognized in Anthurium, only seven of these groups are monophyletic (i.e., sections Andiphilum (Schott) Croat, Calomystrium (Schott) Engl., Dactylophyllium (Schott) Engl., Leptanthurium (Schott) Engl., Polyphyllium Engl., Tetraspermium (Schott) Engl., and the newly recognized section Multinervia (Croat) Carlsen & Croat, previously a series within section Pachyneurium (Schott) Engl.). All other sections are either not monophyletic or their monophyly could not be accurately tested. A complete revision of the sectional classification of Anthurium will require a more comprehensive taxon sampling and a better supported molecular phylogeny.

Three names in the genus Periploca L. are discussed and typified. A specimen preserved at BM and collected by Francis Masson in Tenerife (Canary Islands, Spain) is designated as the neotype of the name P. laevigata Aiton. A Cavanilles illustration is designated as the lectotype of P. punicifolia Cav., a synonym of P. laevigata. Furthermore, a “second-step” lectotypification is published for the name P. angustifolia Labill.

Physalis is an economically important and morphologically diverse genus of plants with solitary flowers and fruits that are enveloped by an inflated fruiting calyx. Although work to resolve phylogenetic relationships in this clade is ongoing, Physalis remains a taxonomically complex genus with multiple nomenclatural problems. Here, we review 28 species from the United States and their synonyms as well as clarification on the status of their types. We propose 53 typifications. We select a lectotype for 49 names and a neotype for three names (P. ixocarpa, P. linkiana, P. ramosissima). We additionally designate an epitype for P. longifolia.

While working on the taxonomic treatment of the family Gunneraceae for the Flora of Argentina, provisional typification for the minute herbaceous species Gunnera lobata and G. magellanica, and the giant herb G. tinctoria, as well as for some of their synonyms, was detected. Here, we designate lectotypes for G. lobata, G. magellanica, G. falklandica (= G. magellanica), and Panke tinctoria (= G. tinctoria), a neotype for G. reichei (= G. magellanica), and an epitype for G. tinctoria. Durante la preparación del tratamiento taxonómico de la familia Gunneraceae para la Flora Argentina, se detectaron designaciones de tipificación preliminares para las especies herbáceas diminutas Gunnera lobata y G. magellanica y la hierba gigante G. tinctoria, así como para algunos de sus sinónimos. Aquí designamos los lectotipos de G. lobata, G. magellanica, G. falklandica (= G. magellanica) y Panke tinctoria (= G. tinctoria), el neotipo de G. reichei (= G. magellanica) y el epitipo de G. tinctoria.

The present lectotypification of the Caucasian endemic Allium saxatile M.Bieb. is found ineffective and falling outside the current concept of the species. The original collections of A. saxatile were destroyed during the Russian Civil War, and conservation of this name is suggested to avoid its lectotypification from remaining illustrations which belong to the Siberian species A. stellerianum and A. rubens. This conservation would also remove the illegitimacy of A. saxatile M.Bieb. caused by homonymy with the overlooked earlier name A. saxatile Pall. The original material of A. caucasicum is identified and discussed, and the name is typified with an illustration referable to A. globosum. Two near-homonyms of A. caucasicum, the originally heterotypic A. caucaseum and A. caucasium are uncovered, and their identity with A. globosum is ascertained.
