“…These estimates are in the upper range of those inferred from microsatellites (Piñeiro et al., ) but should be more reliable because they essentially depend on a molecular clock calibrated by fossil evidence and do not require a priori assumptions regarding effective population sizes or generation time. However, as our calibration nodes pre‐date the divergence between the subfamilies Annonoideae and Malmeoideae (to which Greenwayodendron belongs) with a substitution rate higher in the Annonoideae (Hoekstra et al., ), the beast analyses may have converged on a posterior distribution of substitution rates that matches that of the Annonoideae, thus resulting in an underestimate of the ages presented here.…”

Aim Palaeoecological records indicate that Pleistocene glaciations affected the African rain forest, probably causing its fragmentation, which could explain phylogeographical breaks documented in many tree species. This refuge hypothesis was further tested through species distribution models, hindcasting persistence during the Last Glacial Maximum. However, previous studies failed to estimate with sufficient precision the divergence time between phylogeographical entities to confirm their Pleistocene origin. Developing genomic tools on a representative tree of mature rain forests, we test if parapatric genetic clusters documented in widespread tree species can be interpreted as the legacy of past population fragmentation during the last glacial period(s). Location Tropical Africa, Guineo‐Congolian forests. Taxon Greenwayodendron (Annonaceae). Methods To further test the Pleistocene refuge hypothesis by molecular dating, we sequenced the plastome of 145 individuals of the shade‐tolerant rain forest tree Greenwayodendron suaveolens and congeneric species, and genotyped the same samples using nuclear microsatellites to identify genetic clusters. Results Five plastid phylogroups of G. suaveolens occur in parapatry throughout Central Africa, following a spatial pattern generally congruent with genetic clusters. Four of them diverged 3.5–4.5 Ma, whereas the fifth one, located in the Cameroon volcanic line (CVL), diverged 8.3 Ma, in the range of divergence times between Greenwayodendron species, highlighting the key role of the CVL in hosting ancient lineages. Within phylogroups, most nodes were dated from 0.9 to 3.2 Myr and a correlation between haplotype divergence and spatial distance was still perceptible, indicating a slow population dynamic. Main conclusions The phylogeographical structures of Central African trees probably established during the Pliocene or early Pleistocene, and while they might have been reinforced during subsequent glacial–interglacial cycles, interglacial phases did not lead to genetic homogenization. Therefore, interpreting phylogeographical patterns of African trees must account for a much deeper past than previously assumed, and cannot be limited to the last glacial period.

“…This also applies to larger genera in the faster evolving Annonoideae, the challenge of Guatteria (Erkens et al 2007) being a case in point. One alternative currently being explored is to expand plastid datasets using high throughput sequencing (Hoekstra et al 2017; Lopes et al 2018). Whole plastid sequences might be expected to deliver a well-resolved plastid gene tree, but particularly at low taxonomic levels, this might differ markedly from the underlying species tree (Doyle 1992; Maddison 1997).…”

We present a taxonomic revision of Cremastosperma, a genus of Neotropical Annonaceae occurring in lowland to premontane wet forest, mostly in areas surrounding the Andean mountain chain. We recognise 34 species, describing five as new here: from east of the Andes, C.brachypodum Pirie & Chatrou, sp. nov. and C.dolichopodum Pirie & Maas, sp. nov., endemic to Peru; C.confusum Pirie, sp. nov., from southern Peru and adjacent Bolivia and Brazil; and C.alticola Pirie & Chatrou, sp. nov., at higher elevations in northern Peru and Ecuador; and from west of the Andes, C.osicola Pirie & Chatrou, sp. nov. endemic to Costa Rica, the most northerly distributed species of the genus. We provide an identification key, document diagnostic characters and distributions and provide illustrations and extensive lists of specimens, also presenting the latter in the form of mapping data with embedded links to images available online. Of the 34 species, 22 are regional endemics. On the basis of the extent of occurrence and area of occupancy of species estimated from the distribution data, we designate IUCN threat categries for all species. Fourteen species proved to be endangered (EN) and a further one critically endangered (CR), reflecting their rarity and narrow known distributions.

“…Different palynological and morphological studies have been conducted in the Annonaceae (Doyle & Le Thomas, , ) which have been highly informative for classifying the different groups in this family (Doyle & Le Thomas, ). More recently, molecular phylogenetic studies mainly using plastid regions ( rbcL, matK, ndhF, trnL, trnT‐L, trnL‐F, trnS‐G, atpB‐rbcL, trnH‐psbA, ycf1, rpl32‐trnL, or ndhF‐rpl32 ) have provided valuable information on specific and general aspects of the Annonaceae (Mols et al, ; Richardson et al, ; Pirie et al, ; Chatrou et al, ; Erkens et al, ; Thomas et al, ; Chaowasku et al, ; Larranaga & Hormaza, ; Tang et al, ; Guo et al, ; Hoekstra et al, ). Annona , described by Linnaeus () and further clarified by Safford (), includes approximately 162 species (Chatrou et al, ), distributed mainly in the Neotropics, with a few species native to Africa.…”

Annona cherimola is a woody perennial species in the Annonaceae family that produces edible fruits and has economic importance in several regions of the world with subtropical climates. Together with other 10‐12 species, A. cherimola belongs to the section Atta of the Annona genus with a center of origin in Central America and the Caribbean. Species of the section Atta produce soft skin ripe fruits with raised areoles bounded by recessed furrows. Annona cherimola is the only species of the section naturally found in the Andean region of South America. Currently, no information is available at the molecular level on the phylogenetic relationships of most of the species of Atta and closely related sections in Annona. In order to fill this gap, in this work a phylogenetic approach was performed using five coding and non‐coding plastid DNA regions, to determine the phylogenetic relationships between A. cherimola and other related species included in Atta and other sections of the genus. The results obtained support recent studies that demonstrated the likely Mesoamerican origin of A. cherimola based on biogeographical analysis with SSR markers, rather than the previously considered South American origin hypothesis. In addition, the species belonging to the Atta section did not show monophyly. Finally, A. cherimola and A. pruinosa seem to be phylogenetically close species and additional studies are needed to discern the relations between them.
