Revisions of Ruizodendron and Pseudephedranthus (Annonaceae) including a new species and an overview of most up-to-date revisions of Neotropical Annonaceae genera.
TLDR
In this paper, the Neotropical genera Ruizodendron and Pseudephedranthus (Annonaceae) have been extended beyond the Upper Rio Negro region of Brazil (Amazonas) and adjacent Venezuela (P. fragrans), to include Guyana, Suriname, and the Brazilian state of Para.Abstract:
We present revisions of the Neotropical genera Ruizodendron and Pseudephedranthus (Annonaceae). Ruizodendron includes a single species R. ovale. Pseudephedranthus now comprises two species, with the description of the new species P. enigmaticus sp. nov. extending the range of the genus beyond the Upper Rio Negro region of Brazil (Amazonas) and adjacent Venezuela (P. fragrans), to include Guyana, Suriname, and the Brazilian state of Para. An overview is provided of current revisions of Neotropical Annonaceae genera that will aid in accessing proper species information for this frequently encountered tropical rain forest family.read more

Accelerated diversification correlated with functional traits shapes extant diversity of the early divergent angiosperm family Annonaceae.

TL;DR: The 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 diverification rates.

Genus Huberantha (Annonaceae) Revisited: Erection of Polyalthiopsis, a New Genus for H. floribunda, with a New Combination H. luensis

TL;DR: The identity of an enigmatic species Huberantha floribunda (Annonaceae) is reassessed using molecular phylogenetic analyses of up to seven combined plastid markers and a new combination for Polyalthiopsis luensis is made based on an integrative approach of morphological examination coupled with molecular phylogenetics inferences.

Morgon,Jackson Roberto Guedes da Silva Almeida,Felipe M. A. da Silva,Emmanoel V. Costa,Hector H. F. Koolen +13 more
TL;DR: Twenty-four known alkaloids were dereplicated from the D. surinamensis alkaloid-rich fraction network and were assigned by manual MS/MS interpretation and their cytotoxic potential was evaluated.

Phylogenomics and evolution of floral traits in the Neotropical tribe Malmeeae (Annonaceae)
Jenifer de Carvalho Lopes,Lars W. Chatrou,Renato de Mello-Silva,Paula J. Rudall,Maria das Graças Sajo +4 more
TL;DR: The morphology of male and bisexual flowers of Pseudoxandra spiritus-sancti is described, and the evolution of androdioecy in Malmeeae is investigated.

TL;DR: 12 new species of Annona, Guatteria, Klarobelia, Tetrameranthus, and Xylopia are described to illustrate the still underestimated diversity of the Neotropical flora, even in well studied plant groups like Annonaceae.

A new subfamilial and tribal classification of the pantropical flowering plant family Annonaceae informed by molecular phylogenetics

TL;DR: A robust family-wide phylogenetic tree and subsequent classification of Annonaceae is presented, for the first time, using a supermatrix of up to eight plastid markers sequenced from 193 ingroup and seven outgroup species.

TL;DR: A checklist of all tree species collected to date in Amazonia is provided, and it is found that a species’ range size is a better predictor of the number of times it has been collected than thespecies’ estimated basin-wide population size.

‘Andean‐centred’ genera in the short‐branch clade of Annonaceae: testing biogeographical hypotheses using phylogeny reconstruction and molecular dating
TL;DR: Whether Andean‐centred plant groups could have originated on the South American continent during the time frame of the Andean orogeny is tested by reconstructing phylogeny in the short‐branch clade (SBC) of Annonaceae, and estimating the timing of diversifications in four apparently Andean-centred genera.
Flowers of annonaceae: Morphology, classification, and evolution
TL;DR: The present paper describes the diversity in floral characters of Annonaceae and their distribution over the family, and discusses their value for classification and generic delimitation, and learns that floral characters different from those in previous classifications should be used if one aims at a better correlation with non-floral features.

A revision of Asimina and Deeringothamnus (Annonaceae).
TL;DR: The Annonaceae, a woody tropical or sub-tropical family of flowering plants, are represented in the United States and Canada by eleven species, one of which is the northernmost-ranging member of a large, principally tropical America~l genus and is itself restricted in theUnited States to southern peninsular Florida and the Florida Keys.
