Biologists are fascinated by species-rich groups and have attempted to discover the causes for their abundant diversification. Comprehension of the causes and mechanisms underpinning radiations and detection of their frequency will contribute greatly to the understanding of the evolutionary origin of biodiversity and its ecological structure. A dated and well-resolved phylogenetic tree of Annonaceae was used to study diversification patterns in the family in order to identify factors that drive speciation and the evolution of morphological (key) characters. It was found that, except for Goniothalamus, the largest genera in the family are not the result of radiations. Furthermore, the difference in species numbers between subfamilies Annonoideae (former long branch clade) and Malmeoideae (former short branch clade) cannot be attributed to significant differences in the diversification rate. Most of the speciation in Annonaceae is not distinguishable from a random branching process (i.e. chance), and no special explanations are therefore necessary for the distribution of species richness across the major part of the phylogenetic tree for Annonaceae. Only for a small number of clades can key innovations be invoked to explain the elevated rate of diversification. © 2012 The Linnean Society of London, Botanical Journal of the Linnean Society, 2012, 169, 117–134.

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.x00570nas a2200145 4500008004100000020001400041245015900055210006900214300001400283490000700297100002100304700001800325700002600343856005500369 2009 eng d a1365-269900aFrom Africa via Europe to South America: migrational route of a species-rich genus of Neotropical lowland rain forest trees (Guatteria, Annonaceae)0 aFrom Africa via Europe to South America migrational route of a s a2338-23520 v361 aErkens, Roy, H J1 aMaas, Jan., W1 aCouvreur, Thomas, L P uhttp://dx.doi.org/10.1111/j.1365-2699.2009.02162.x02224nas a2200241 4500008004100000245013100041210006900172300001200241490000700253520141300260653001501673653001401688653001401702653001501716653002101731653002601752100002101778700002101799700001701820700002001837700002401857856010101881 2007 eng d00aA rapid diversification of rainforest trees (Guatteria; Annonaceae) following dispersal from Central into South America0 arapid diversification of rainforest trees iGuatteriai Annonaceae a399-4110 v443 a

Several recent studies have suggested that a substantial portion of today's plant diversity in the Neotropics has resulted from the dispersal of taxa into that region rather than vicariance, but more data are needed to substantiate this claim. Guatteria (Annonaceae) is, with 265 species, the third largest genus of Neotropical trees after Inga (Fabaceae) and Ocotea (Lauraceae), and its widespread distribution and frequent occurrence makes the genus an excellent model taxon to study diversification patterns. This study reconstructed the phylogeny of Guatteria and inferred three major biogeographical events in the history of the genus: (1) a trans-oceanic Miocene migration from Central into South America before the closing of the Isthmus of Panama; (2) a major diversification of the lineage within South America; and (3) several migrations of South American lineages back into Central America via the closed Panamanian land bridge. Therefore, Guatteria is not an Amazonian centred-genus sensu Gentry but a major Miocene diversification that followed its dispersal into South America. This study provides further evidence that migration into the Neotropics was an important factor in the historical assembly of its biodiversity. Furthermore, it is shown that phylogenetic patterns are comparable to those found in Ocotea and Inga and that a closer comparison of these genera is desirable.
