Background A major goal of phylogenetic systematics is to understand both the patterns of diversification and the processes by which these patterns are formed. Few studies have focused on the ancient, species-rich Magnoliales clade and its diversification pattern. Within Magnoliales, the pantropically distributed Annonaceae are by far the most genus-rich and species-rich family-level clade, with c. 110 genera and c. 2,400 species. We investigated the diversification patterns across Annonaceae and identified traits that show varied associations with diversification rates using a time-calibrated phylogeny of 835 species (34.6% sampling) and 11,211 aligned bases from eight regions of the plastid genome (rbcL, matK, ndhF, psbA-trnH, trnL-F, atpB-rbcL, trnS-G, and ycf1). Two hypotheses that might explain patterns of diversification—the ‘museum model’ and heterogeneous diversification rates—are also evaluated. Results Twelve rate shifts were identified using BAMM: in Annona, Artabotrys, Asimina, Drepananthus, Duguetia, Goniothalamus, Guatteria, Uvaria, Xylopia, the tribes Miliuseae and Malmeeae, and the Desmos-Dasymaschalon-Friesodielsia-Monanthotaxis clade (which collectively account for over 80% of the total species richness in the family). TurboMEDUSA and method-of-moments estimator analyses showed largely congruent results. A positive relationship between species richness and diversification rate is revealed using PGLS. We further explore the possible role of selected traits (habit, pollinator trapping, floral sex expression, pollen dispersal unit, anther septation, and seed dispersal unit) in shaping diversification patterns, based on inferences of BiSSE, MuSSE, HiSSE, and FiSSE analyses. Our results suggest that the liana habit, the presence of circadian pollinator trapping, androdioecy, and the dispersal of seeds as single-seeded monocarp fragments are closely correlated with higher diversification rates; pollen aggregation and anther septation, in contrast, are associated with lower diversification rates. Conclusion Our results show that the high species richness in Annonaceae is likely the result of recent increased diversification rather than the steady accumulation of species via the ‘museum model’. BAMM, turboMEDUSA, and the method-of-moments estimator all indicate heterogeneity in diversification rates across the phylogeny, with different traits associated with shifts in diversification rates in different Annonaceae clades.

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.

“…Annonaceae, a pantropical family of flowering plants prominent in lowland rainforests, consist of 110 genera (Guo et al 2017;Chaowasku et al 2018a;Xue et al 2018) and approximately 2430 species (Chatrou et al 2018). The family has been classified into four subfamilies, viz., Anaxagoreoideae, Ambavioideae, Annonoideae, and Malmeoideae; the last two subfamilies, which constitute the majority of generic and species diversity in the family, have each been further subdivided into tribes (Chatrou et al 2012).…”

A molecular phylogeny of the subfamily Ambavioideae (Annonaceae) was reconstructed using up to eight plastid DNA regions (matK, ndhF, and rbcL exons; trnL intron; atpB-rbcL, psbA-trnH, trnL-trnF, and trnS-trnG intergenic spacers). The results indicate that the subfamily is not monophyletic, with the monotypic genus Meiocarpidium resolved as the second diverging lineage of Annonaceae after Anaxagorea (the only genus of Anaxagoreoideae) and as the sister group of a large clade consisting of the rest of Annonaceae. Consequently, a new subfamily, Meiocarpidioideae, is established to accommodate the enigmatic African genus Meiocarpidium. In addition, the subfamily Ambavioideae is redefined to contain two major clades formally recognized as two tribes. The tribe Tetramerantheae consisting of only Tetrameranthus is enlarged to include Ambavia, Cleistopholis, and Mezzettia; and Canangeae, a new tribe comprising Cananga, Cyathocalyx, Drepananthus, and Lettowianthus, are erected. The two tribes are principally distinguishable from each other by differences in monoploid chromosome number, branching architecture, and average pollen size (monads). New relationships were retrieved within Tetramerantheae, with Mezzettia as the sister group of a clade containing Ambavia and Cleistopholis.

A linear sequence to facilitate curation of herbarium specimens of Annonaceae

Abstract: Summary. This paper provides a linear sequence of four subfamilies, 15 tribes and 106 genera of the magnoliid family Annonaceae, based on state-of-the-art and stable phylogenetic relationships. The linear sequence facilitates the organisation of Annonaceae herbarium specimens.
