A phylogenetic study to investigate the putative monophyly of the tribe and the intergeneric relationships is presented here. Nucleotide sequences of the plastid gene rbcL, trnL intron, and trnL-trnF intergenic spacer were analyzed from 114 Annonaceae taxa, including 24 Miliuseae species and two outgroups using maximum parsimony and Bayesian inference. The two data sets (rbcL and the trnL-trnF regions) were analyzed separately and in combination. Miliuseae were found to be polyphyletic due to the position of Mezzettia and are part of a large, predominantly Asian and Central-American clade (miliusoid clade). Although intergeneric relationships were poorly resolved, all genera, except Polyalthia, were monophyletic, supporting previous generic delimitation based on morphology. A group of three Polyalthia species seems the most likely sister group of Miliusa. Several infrageneric groups of Miliusa, Orophea, and Polyalthia are supported by both molecular and morphological data. No morphological synapomorphies have yet been found for the miliusoid clade. Molecular clades within the miliusoid clade, however, can be characterized by size and the shape of the outer petals, number of ovules per carpel, and the size of the fruits.1 aMols, J.B.1 aCo, D.L.V.1 aGravendeel, B.1 aChatrou, L W1 aPirie, M D1 avan der Ham, R.W.J.M.1 avan Marle, E.J.1 aKessler, P.J.A.1 aMols, J.B.  uhttps://annonaceae.myspecies.info/node/535700437nas a2200133   4500008004100000020001400041245008200055210006900137300001000206490000700216100001700223700001500240856004800255       2005                        eng d  a0006-519600aThree new rarely collected or endangered species of Annonaceae from Venezuela0 aThree new rarely collected or endangered species of Annonaceae f  a33-400 v501 aChatrou, L W1 aPirie, M D  uhttps://annonaceae.myspecies.info/node/495603447nas a2200181   4500008004100000245015600041210006900197260000800266300001000274490000700284520285800291100001503149700001703164700001403181700001803195700001703213856003503230       2006                        eng d00a'Andean-centred' genera in the short-branch clade of Annonaceae: testing biogeographical hypotheses using phylogeny reconstruction and molecular dating0 aAndeancentred genera in the shortbranch clade of Annonaceae test  cJan  a31-460 v333 aAim We test biogeographical hypotheses regarding the origin of Andean-centred plant groups by reconstructing phylogeny in the short-branch clade (SBC) of Annonaceae, and estimating the timing of diversifications in four apparently Andean-centred genera: Cremastosperma R.E.Fr., Klarobelia Chatrou, Malmea R.E.Fr. and Mosannona Chatrou. The SBC includes species distributed in both the Old and New World tropics. A number of the Neotropical genera display 'Andean-centred' distribution patterns, with high species richness on both sides of the Andes mountain range. In particular, we test whether these groups could have originated on the South American continent during the time frame of the Andean orogeny [from c. 23 Ma (Miocene) to the present]. Methods Chloroplast DNA sequences were used to reconstruct phylogeny in related Annonaceae taxa plus outgroups, under maximum parsimony and Bayesian inference. The markers rbcL, trnL-trnF and psbA-trnH were sampled for 96 accessions to test the monophyly of each of the genera, and thus whether they might be para- or polyphyletic with respect to related groups distributed across Amazonia. To determine the sister groups of the four genera, the additional markers matK, ndhF, trnT-trnL, trnS-trnG and atpB-rbcL were sampled for 23 of the 96 accessions. Molecular dating techniques (nonparametric rate-smoothing; penalized likelihood; Bayesian inference) were then applied to estimate the age of the crown group of each genus and the age of their sister groups. Results Monophyly was confirmed in Cremastosperma, Malmea and Mosannona. The monotypic genus Pseudephedranthus Aristeg. was found to be nested within Klarobelia, the species of which otherwise formed a monophyletic group, and a South American-centred (SAC) clade was identified. The SAC clade comprises all the SBC genera distributed in South America and generally to a limited extent into Central America, but not those endemic to Africa, Asia and Central America. Age estimations for clades within the SBC were no older than around 60 Myr; those for the crown groups of Cremastosperma, Klarobelia, Malmea and Mosannona fell largely within the last 10-20 Myr. Main conclusions The distribution patterns of Cremastosperma, Klarobelia, Malmea and Mosannona are not the arbitrary result of the definition of para- or polyphyletic groups. We infer the presence of a common ancestor of the four genera in South America, but not by vicariance of an ancestral population on Gondwana. The age estimations, instead, may suggest that the SAC clade originated in South America by dispersal across the Boreotropics. Although the strength of this test was limited by imprecision in the molecular dating results, the ages of crown groups of the four genera suggest that diversifications occurred within the time frame of the orogeny of the Northern Andes.1 aPirie, M D1 aChatrou, L W1 aMols, J B1 aErkens, R H J1 aOosterhof, J  u<Go to ISI>://000234412800005 00618nas a2200157   4500008004100000245010500041210006900146300001400215490000800229100002000237700001700257700001400274700001800288700001500306856013900321       2004                        eng d00aHistorical biogeography of two cosmopolitan families of flowering plants: Annonaceae and Rhamnaceae.0 aHistorical biogeography of two cosmopolitan families of flowerin  a1495-15080 v3591 aRichardson, J E1 aChatrou, L W1 aMols, J B1 aErkens, R H J1 aPirie, M D  uhttps://annonaceae.myspecies.info/content/historical-biogeography-two-cosmopolitan-families-flowering-plants-annonaceae-and-rhamnaceae
