A new Angolan species from the Triaspis hypericoides complex (Malpighiaceae) based on macromorphology and palynology.
currently comprises three accepted subspecies endemic to woodland savannas of southern continental Africa. After an unusual population belonging to this complex was collected in southwestern Angola, we re‐evaluated the classification of this group. This study was based on the analysis of type specimens, protologues, field photographs and herbarium sheets of... -

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.

Annea gen. nov. (Detarieae, Caesalpinioideae, Leguminosae): a home for two species long misplaced in Hymenostegia sensu lato.
A new genus Annea is described to accommodate two tropical African legume species previously misplaced in Hymenostegia (Leguminosae, Caesalpinioideae, Detarieae). Annea gen. nov. is widespread in tropical Africa but has an unusual disjunct generic distribution, occurring in both upper and lower Guinea but absent from Gabon. Annea afzelii accounts for...Mackinder, Barbara A. ; Wieringa, Jan J.

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... -

Sixty-seven species newly recorded for the flora of Angola: recent findings from vegetation surveys and herbarium collections.
Angola is a tropical country with many biogeographical units and, therefore, has a high floristic diversity. Although an increasing number of floristic studies has been carried out in Angola in recent years, the country is still considered to be underinvestigated as many species being collected were previously unknown there. Several... -
