Guatteria (Annonaceae) is with ca. 265 species one of the largest genera of Neotropical trees together with Inga and Ocotea. Use of Guatteria in evolutionary studies has been hampered by taxonomic problems caused by lack of morphological variability in the genus. This study focuses on molecular phylogenetic relationships within Guatteria and its satellites Guatteriopsis, Guatteriella and Heteropetalum, and implications of these relationships for classification and character evolution. Results show that Guatteriopsis, Guatteriella and Heteropetalum should be merged with Guatteria. Heteropetalum may be recognized at subgeneric level because of its aberrant morphology and Guatteriopsis and Guatteriella might be given sectional status. Most of the currently recognised sections in Guatteria are probably non-monophyletic. A completely new infrageneric classification of Guatteria would be premature, however, due to the lack of molecular and morphological synapomorphies to define the sections. Synapomorphies defining Guatteria s.str. probably evolved after divergence of several early branching lineages.

“…This analysis narrowed the possible relationships of Rhizophoraceae/Anisophylleaceae to the rosid clades. (2) Accordingly, we next sampled representatives of each family in the rosid clade for which rbcL sequences were available, guided by phylogenetic analyses of groups within this clade (Albert, Williams, and Chase, 1992;Price and Palmer, 1993;Swensen, Mullin, and Chase, 1994;Conti, Litt, and Sytsma, 1996;Swensen, 1996;Fay, Swensen, and Chase, 1997;Savolainen, Spichinger, and Manen, 1997;Alverson et al, 1998;Fay et al, 1998). When sequences for several species of one family were available, we chose one or two representative species.…”

“…Herbarium and silica gel-dried material was ground in a dry state before adding extraction buffer, while the frozen material was ground after adding extraction buffer. DNA amplifications were performed in 50 u,L reactions containing 1.25U Taq polymerase (Promega, Madison, Wisconsin, USA), reaction buffer A supplied by Promega, 1.5 mmol/L MgCl 2 , 25 pmol of each primer and 0.2 mmol/L of each dNTR The flanking primer sequences for rbcL (IF and 1460R) were used as in Fay et al (1998); additional internal primers were designed for maximum fit in the Rhizophoraceae (674F: 5 -TTTATAAAGCACA-GGCGGAA-3'; 795R: 5 -CTGTTAAGTAGTCATGCATT-3'). The trnL-trnF spacer region was amplified using primers E and F from Taberlet et al (1991).…”

A cladistic analysis of sequences from the chloroplast gene rbcL was used to determine the systematic affinities of Rhizophoraceae and Anisophylleaceae. This analysis rejects close relationships of Rhizophoraceae with Celastraceae or Elaeocarpaceae, suggested previously, and identifies Erythroxylaceae as sister group within the Malpighiales, supported by several morphological and anatomical characters. Our molecular results also indicate that Anisophylleaceae are nested within Cucurbitales. Although this placement is novel, this affinity is also well supported by shared morphological characters. Tribal and generic relationships within Rhizophoraceae are evaluated with a combination of six molecular data sets (rbcL, atpB-rbcL intergenic spacer, trnL-trnF intergenic spacer, ITS1, ITS2, and 5.8S) and a morphological data set. These relationships are compared with results from previous morphological cladistic analyses. Against the background of the molecular results, we briefly discuss the evolution of morphological characters traditionally used for tribal subdivision as well as characters presumably significant for adaptation to mangrove habitats, namely, aerial stilt roots and vivipary.

a b s t r a c tWe reconstruct here the spatial and temporal evolution of the Campanula alliance in order to better understand its evolutionary history. To increase phylogenetic resolution among major groups (Wahlenbergieae-Campanuleae), new sequences from the rbcL region were added to the trnL-F dataset obtained in a previous study. These phylogenies were used to infer ancestral areas and divergence times in Campanula and related genera using a Bayesian approach to molecular dating and dispersal-vicariance analyses that takes into account phylogenetic uncertainty. The new phylogenetic analysis confirms Platycodoneae as the sister group of Wahlenbergieae-Campanuleae, the two last ones inter-graded into a well-supported clade. Biogeographic and dating analyses suggest that Western Asia and the Eastern Mediterranean have played a major role as centers of migration and diversification within the Campanula alliance, probably in relation to the intense orogenic activity that took place in this region during the Late Neogene, and that could have promoted isolation and allopatric speciation within lineages. Diversification rates within several Campanula lineages would have increased at the end of the Miocene, coinciding with the Messinian Stage. Strong selective pressures from climate changes and the expansion of mountainous regions during this period are suggested to explain the adaptation to drought, cold or disturbed environments observed in many Campanula species. Several independent long-distance dispersal events to North America are inferred within the Rapunculus clade, which seem to be related to high ploidy levels.
