Molecular phylogenetics of Distephanus supports the recognition of a new tribe, Distephaneae (Asteraceae).
Distephanus Cass. comprises 43 distinctive species of shrubs and small trees that have been placed historically within the ironweed tribe, Vernonieae (Asteraceae). Using the most expansive sampling of Distephanus to date, this study aims to test the monophyly of this genus and facilitate its classification. Molecular phylogenetic analyses were conducted...Gostel, M. R. ; Loeuille, Benoit ; Santana, Mariana Henriques ; Kelloff, Carol L ; Chan, Raymund …

Gabonius gen. nov. (Leguminosae, Caesalpinioideae, Detarieae), a distant cousin of Hymenostegia endemic to Gabon.
A new genus, Gabonius is described to accommodate a single species, Gabonius ngouniensis which was previously misplaced in Hymenostegia sensu lato. Gabonius ngouniensis is a widespread Gabonese endemic of evergreen forest. We assess G. ngouniensis as Least Concern (LC) according to IUCN criteria. A distribution map of Gabonius is presented,...Wieringa, Jan J. ; Mackinder, Barbara A. ; Van Proosdij, André S. J.

The bii4africa dataset of faunal and floral population intactness estimates across Africa’s major land uses.
Sub-Saharan Africa is under-represented in global biodiversity datasets, particularly regarding the impact of land use on species’ population abundances. Drawing on recent advances in expert elicitation to ensure data consistency, 200 experts were convened using a modified-Delphi process to estimate ‘intactness scores’: the remaining proportion of an ‘intact’ reference population... -

A new Ypsilopus (Orchidaceae, Angraecinae) from Zimbabwe and notes on the parallel evolution of extreme column exsertion in African angraecoids.
– A preliminary review of hawkmoth-pollinated angraecoids from Africa unveiled a remarkable case of parallel evolution of extreme column exsertion between the two species formerly classified in in the defunct genus . These belong to one clade of , including and , and Ypsilopus sect. Barombiella, including and . The... -

Phylogenomic inference of the African tribe Monodoreae (Annonaceae) and taxonomic revision of Dennettia, Uvariodendron and Uvariopsis.
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 and which lack a recent taxonomic revision. Here, we used a robust phylogenomic approach, including all the 90 currently... -

Evolutionary relationships, biogeography and morphological characters of Glinus (Molluginaceae), with special emphasis on the genus composition in Sub-Saharan Africa.
is a small genus of Molluginaceae with 8–10 species mostly distributed in the tropics of the World. Its composition and evolutionary relationships were poorly studied. A new molecular phylogeny constructed here using nuclear (ITS) and chloroplast ( , ) markers confirmed the monophyly of the genus. Based on ITS analysis,... -

Lectotypification of names in Parkia R.Br. (Leguminosae: Caesalpinioideae, mimosoid clade) for Africa and Madagascar.
Ten specific names plus those of three varieties, which refer to the four currently recognised species of in Africa and Madagascar ( A.Chev. (Jacq.) R.Br. ex G.Don Welw. ex Oliv., R.Vig.), are listed. Their types are enumerated with lectotypes indicated where necessary and in a few cases, a second-step lectotypification...Hopkins, Helen C. F.
