This provides a basis for understanding evolutionary shifts in the pollination system within the family. The present study focuses on subfamilies Anaxagoreoideae, Ambavioideae and Annonoideae, for which robust, well-resolved phylogenetic trees are available. Information is summarized on the pollination biology of individual clades and the evolutionary adaptations favouring different pollinator guilds evaluated. Although the majority of species of Annonaceae are pollinated by small beetles, five other pollinator groups are known: large beetles, thrips, flies, bees and cockroaches. Small-beetle pollination is inferred as the ancestral pollination system, with all other systems being derived. Evolutionary shifts to pollination by large beetles, thrips and flies are unlikely to have been significantly constrained by previous adaptations favouring pollination by small beetles, as many of the adaptations to these different pollinator guilds are similar (including protogyny, partially enclosed floral chambers and olfactory cues). In contrast, however, the evolutionary shift to bee pollination has presumably been constrained by both protogyny (as pollen-collecting bees are unlikely to visit pistillate-phase flowers) and the presence of floral chambers. © 2012 The Linnean Society of London, Botanical Journal of the Linnean Society, 2012, 169, 222–244.10acantharophily10apollination ecology10areproductive biology1 aSaunders, Richard, M K uhttp://dx.doi.org/10.1111/j.1095-8339.2011.01208.x01822nas a2200241 4500008004100000020001400041245015400055210006900209260002900278300001000307490000800317520102200325653001901347653002401366653001701390653001601407653001601423100001701439700002001456700002201476700002701498856005501525 2010 eng d a1095-833900aMolecular phylogenetics of Uvaria (Annonaceae): relationships with Balonga, Dasoclema and Australian species of Melodorum0 aMolecular phylogenetics of iUvaria iAnnonaceae relationships wit bBlackwell Publishing Ltd a33-430 v1633 aAn extended molecular phylogenetic analysis of Uvaria (Annonaceae) is presented, using maximum parsimony, maximum likelihood and Bayesian methods, based on sequences of four plastid DNA regions (matK, psbA-trnH spacer, rbcL and trnL-F). The additional taxa include the monotypic West African genus Balonga, the monotypic South-East Asian genus Dasoclema and seven Australian representatives of the genus Melodorum. The results indicate that all of these taxa are nested within a well-supported clade otherwise consisting of Uvaria species, indicating that their taxonomic treatment needs to be reassessed. The distinguishing morphological characteristics of the taxa are re-evaluated and interpreted as specialized adaptations of the basic Uvaria structure. The genus Uvaria is accordingly extended following the transfer of these species, necessitating six new nomenclatural combinations and two replacement names. © 2010 The Linnean Society of London, Botanical Journal of the Linnean Society, 2010, 163, 33–43.10aclassification10amolecular phylogeny10anomenclature10aplastid DNA10aSYSTEMATICS1 aZhou, Linlin1 aSu, Yvonne, C F1 aChalermglin, Piya1 aSaunders, Richard, M K uhttp://dx.doi.org/10.1111/j.1095-8339.2010.01045.x
