	abstract = {We present revisions of the Neotropical genera Ruizodendron and Pseudephedranthus (Annonaceae). 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 Par{\'a}. 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.},

	abstract = {As 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.},

	abstract = {It 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.~{\textcopyright} 2012 The Linnean Society of London, Botanical Journal of the Linnean Society, 2012, 169, 41{\textendash}73.},
