Although Polyalthia has recently been reduced in taxonomic scope, the remaining species in the genus still form a phylogenetically disparate and morphologically heterogeneous assemblage. We use maximum parsimony, maximum likelihood and Bayesian phylogenetic reconstructions based on chloroplast DNA sequence data (matK, rbcL, trnL-F) to show that the remaining Polyalthia species segregate into three clades: a clade sister to Miliusa; a clade that also includes all Enicosanthum and Woodiellantha species sampled, sister to Neo-uvaria; and a clade that also includes all Haplostichanthus species sampled, inferred (based on previous research) to be sister to Popowia. Diagnostic morphological and anatomical characters are evaluated for the latter two clades, and diagnostic leaf and seed characters identified. Based on these results, the generic name Monoon is resurrected for the clade that includes Enicosanthum and Woodiellantha, following the transfer of 37 species from Polyalthia s.l., 18 species from Enicosanthum and the single Woodiellantha species. The generic name Haplostichanthus is furthermore synonymised with Polyalthia s.str., necessitating nine nomenclatural changes, including six new combinations and three replacement names.}, keywords = {Annonaceae, ENICOSANTHUM, HAPLOSTICHANTHUS, MOLECULAR PHYLOGENETICS, MONOON, nomenclature, POLYALTHIA, taxonomy, WOODIELLANTHA}, author = {Xue, Bine and Su, Yvonne C.

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.~{\textcopyright} 2012 The Linnean Society of London, Botanical Journal of the Linnean Society, 2012, 169, 222{\textendash}244.}, keywords = {cantharophily, pollination ecology, reproductive biology}, isbn = {1095-8339}, author = {Saunders, Richard M.

Despite long-standing interest in the systematics of Annonaceae, no authoritative classification has yet been published in the light of recent molecular phylogenetic analyses. Here, using the largest, most representative, molecular dataset compiled on Annonaceae to date, we present, for the first time, a robust family-wide phylogenetic tree and subsequent classification. We used a supermatrix of up to eight plastid markers sequenced from 193 ingroup and seven outgroup species. Some of the relationships at lower taxonomic levels are poorly resolved, but deeper nodes generally receive high support. Annonaceae comprises four major clades, which are here given the taxonomic rank of subfamily. The description of Annonoideae is amended, and three new subfamilies are described: Anaxagoreoideae, Ambavioideae and Malmeoideae. In Annonoideae, seven tribes are recognized, one of which, Duguetieae, is described as new. In Malmeoideae, seven tribes are recognized, six of which are newly described: Dendrokingstonieae, Fenerivieae, Maasieae, Malmeeae, Monocarpieae and Piptostigmateae. This new subfamilial and tribal classification is discussed against the background of previous classifications and characters to recognize subfamilies are reviewed.~{\textcopyright} 2012 The Linnean Society of London, Botanical Journal of the Linnean Society, 2012, 169, 5{\textendash}40.}, keywords = {plastid markers, subfamilies, supermatrix, tribes}, isbn = {1095-8339}, author = {Chatrou, Lars W. and Pirie, Michael D. and Erkens, Roy H.
