A revision of the 45 species of the pantropical genus Xylopia in Tropical Africa includes descriptions of six new species and a new section of the genus. The fruits and seeds of Xylopia show specializations that promote vertebrate dispersal, primarily by hornbills and monkeys. Over half of the African species have an Area of Occupancy (AOO) less than 80 km2, suggesting that they are in need of protection. African species are classified into five sections. Section Neoxylopia, with four species… 

A revision of Xylopia L. (Annonaceae): the species of Madagascar and the Mascarene islands

TLDR
Taxonomic review supports the hypothesis that the genus dispersed to Madagascar from continental Africa five times, and ten new species are described: Xylopia anomala D.M.Johnson & N.A.Murray, sp.

Flora of Cameroon – Annonaceae Vol 45

TLDR
This volume of the Flora of Cameroon describes 166 native taxa representing 163 species in 28 native genera within the family Annonaceae, a major pantropical family with 113 genera and about 2550 species.

Monanthotaxis bali (Annonaceae) a new Critically Endangered (possibly extinct) montane forest treelet from Bali Ngemba, Cameroon

TLDR
The new Monanthotaxis bali is unusual in being a treelet in a predominantly lianescent genus, and in lacking the glaucous underside of the leaf-blades that usually characterises the genus.

A taxonomic revision of the Neotropical genus Cremastosperma (Annonaceae), including five new species

TLDR
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, identifies 34 species and designate IUCN threat categries for all species.

Lukea gen. nov. (Monodoreae-Annonaceae) with two new threatened species of shrub from the forests of the Udzungwas, Tanzania and Kaya Ribe, Kenya

TLDR
The genus Lukea is erected for two new species to science, Lukea quentinii Cheek & Gosline from Kaya Ribe, SE Kenya, and Lukea triciae from the Udzungwa Mts, Tanzania, and the placement of Lukea within the Uvariopsis clade is discussed.

Biogeography and ecology in a pantropical family, the Meliaceae

  • M. Heads
  • Environmental Science
    Gardens' Bulletin Singapore
  • 2019
TLDR
Whether the evolution of Meliaceae can be attributed to ‘radiations’ from restricted centres of origin into new morphological, geographical and ecological space, or whether it is better explained by phases of vicariance in widespread ancestors, alternating with phases of range expansion is discussed.

Twelve new and exciting Annonaceae from the Neotropics

TLDR
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.

Acta Botanica Brasilica

TLDR
A molecular phylogeny of the subfamily Ambavioideae (Annonaceae) was reconstructed, indicating that the sub family is not monophyletic, with the monotypic genus Meiocarpidium resolved as the second diverging lineage of Annonaceae.

Molecular phylogeny of Annonaceae species from Binh Chau-Phuoc Buu Nature Reserve based on two chloroplast gene regions

TLDR
The matK and trnL-F regions of ten Annonaceae species grown in Binh Chau-Phuoc Buu Nature Reserve, Vietnam were successfully amplified and sequenced for the first time and the molecular phylogeny of ten studied species was established.

TLDR
The genus Hexalobus consists of five species characterized by six basally fused petal lobes that are transversally folded in bud, which is unique within Annonaceae, and is restricted to continental Africa.

The evolution of African plant diversity

  • H. Linder
  • Environmental Science

TLDR
It is argued that six floras, with distinct geographical centres, different extra-African affinities, ages of radiation and radiation rates, can be delimited: the Austro-temperate, Tropic-alpine, Lowland forest,tropic-montane, Savanna and Arid Floras.

Plastid and Seed Morphology Data Support a Revised Infrageneric Classification and an African Origin of the Pantropical Genus Xylopia (Annonaceae)

TLDR
The phylogenetic results suggest an African origin for the genus Xylopia and reveal complex biogeographic patterns, likely facilitated by long-distance dispersal.
