Ruizodendron includes a single species R. ovale. Pseudephedranthus now comprises two species, with the description of the new species P. enigmaticus sp. nov. extending the range of the genus beyond the Upper Rio Negro region of Brazil (Amazonas) and adjacent Venezuela (P. fragrans), to include Guyana, Suriname, and the Brazilian state of Pará. An overview is provided of current revisions of Neotropical Annonaceae genera that will aid in accessing proper species information for this frequently encountered tropical rain forest family.1 aErkens, Roy1 aOosterhof, Jessica1 aWestra, Lubbert Th, Y1 aMaas, Paul, J M  uhttps://phytokeys.pensoft.net/article/13773/01430nas a2200217   4500008004100000022001400041245005900055210005900114260000800173300001200181490000800193520081200201100002001013700002601033700002101059700002101080700001801101700002301119700002101142856004901163       2019                        eng d  a1314-200300aTwelve new and exciting Annonaceae from the Neotropics0 aTwelve new and exciting Annonaceae from the Neotropics  cjul  a25–690 v1263 aAs a result of concerted efforts of the community of Annonaceae taxonomists, increasingly detailed knowledge of the diversity of the Neotropical genera has been documented. With the exception of just two large genera, Annona and Xylopia, all Neotropical Annonaceae have been revised within the last 25 years. Subsequent to these publications, many new specimens have been collected and sent to us in Leiden for identification. These included a number that, despite the advanced state of taxonomic knowledge, proved to represent rarely collected, undescribed species. Here we describe 12 new species of Annona, Guatteria, Klarobelia, Tetrameranthus, and Xylopia. These species serve to illustrate the still underestimated diversity of the Neotropical flora, even in well studied plant groups like Annonaceae.1 aMaas, Paul, J M1 aWestra, Lubbert Th, Y1 aChatrou, Lars, W1 aVerspagen, Nadja1 aRainer, Heimo1 aZamora, Nelson, A.1 aErkens, Roy, H J  uhttps://phytokeys.pensoft.net/article/33913/01914nas a2200217   4500008004100000020001400041245005100055210004900106260002900155300001000184490000800194520129000202653001801492653001301510653002501523653002501548100002101573700002101594700002601615856005501641       2012                        eng d  a1095-833900aA concise bibliographic overview of Annonaceae0 aconcise bibliographic overview of Annonaceae  bBlackwell Publishing Ltd  a41-730 v1693 aIt is important that taxonomic knowledge is disseminated by those who possess it. This can be carried out via online databases, printed publications or training in taxonomic practice. For Annonaceae, the online database AnnonBase includes all published names of Annonaceae at any rank worldwide. Recently, an updated index to genera, species and infraspecific taxa of Neotropical Annonaceae was published in hard copy. This manuscript contains a concise update to the Bibliography of Annonaceae published by the late E. A. Mennega in 1993. Since his publication, much work has been carried out on systematics and evolution of Annonaceae, with the advent of molecular phylogenetics providing an additional stimulus. Here, however, we concentrate only on taxonomic papers focusing specifically on the description and circumscription of taxa (e.g. revisions, monographs, floras, checklists, descriptions of new species or phylogenetic studies that show monophyly/polyphyly/paraphyly of genera). The index should provide an easy entrance into the most important taxonomic literature on Annonaceae from 1900 onwards for the trained and untrained taxonomist with an interest in Annonaceae. © 2012 The Linnean Society of London, Botanical Journal of the Linnean Society, 2012, 169, 41–73.10adissemination10aoutreach10ataxonomic impediment10ataxonomic literature1 aErkens, Roy, H J1 aMennega, Erik, A1 aWestra, Lubbert Th, Y  uhttp://dx.doi.org/10.1111/j.1095-8339.2012.01232.x
