Phylogenomic inference of the African Tribe Monodoreae (Annonanceae) and Taxonomic Revision of Dennettia, Uvariodendron and Uvariopsis. 2023. (Phytokeys,233, special issue). 89 figs.(col. photogr., line-drawings and dot maps). 199 p. 4to. Paper bd.

Monodoreae (Annonaceae) is a tribe composed of 11 genera and 90
species restricted to the tropical African rain forests. All the genera
are taxonomically well circumscribed except the species rich genera
Uvariodendron and Uvariopsis which lack a recent taxonomic revision. Here, we infered the phylogenetic tree of the Monodoreae based on a robust phylogenomics approach with more than 300 nuclear genes, and test the limits between the genera and species. We erect a new tribe, Ophrypetaleae, to accommodate the genera Ophrypetalum and Sanrafaelia, as we recover them excluded from the Monodoreae tribe with good support. We reinstate the monotypic genus Dennettia for its single species Dennettia tripetala. Our results support the description of several new species of Uvariodendron and Uvariopsis, as well as new synonymies. Finally, we present a taxonomic revision of the genera Dennettia, Uvariodendron and Uvariopsis, which contain one, 18 and 17 species respectively. We provide a key to the 11 genera of the Monodoraeae and describe four new species to science and provide provisional descriptions of three putatively new species. We also present lectotypifications and nomenclatural changes implying synonymies and new combinations.
