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... -

New species of Asclepias (Apocynaceae), Baphia (Leguminosae), Cochlospermum (Bixaceae) and Endostemon (Lamiaceae) from the Kalahari sands of Angola and NW Zambia, with one new combination in Vangueria (Rubiaceae).
Four new species are described from central and eastern Angola and adjacent NW Zambia. All occur in Kalahari sand savannas rich in endemic and more widely distributed geoxylic suffrutices. Despite being known from very few collections, the conservation status of one of these new species is assessed as Least Concern,... -

Genomic insights into rapid speciation within the world’s largest tree genus Syzygium.
Species radiations, despite immense phenotypic variation, can be difficult to resolve phylogenetically when genetic change poorly matches the rapidity of diversification. Genomic potential furnished by palaeopolyploidy, and relative roles for adaptation, random drift and hybridisation in the apportionment of genetic variation, remain poorly understood factors. Here, we study these aspects...Low, Yee Wen ; Rajaraman, Sitaram ; Tomlin, Crystal M. ; Ahmad, Joffre Ali ; Ardi, Wisnu H. …

The Cuito catchment of the Okavango system: a vascular plant checklist for the Angolan headwaters.
This paper aims to provide a baseline for conservation planning by documenting patterns of plant diversity and vegetation in the upper catchment of the Cuito River. 417 species are recorded from this region. Nine of these are species potentially new to science. Ten species are newly recorded from Angola, with...Goyder, David J. ; Barker, Nigel ; Bester, Stoffel P. ; Frisby, Arnold ; Janks, Matt …

Further new species and records from the coastal dry forests and woodlands of the Rovuma Centre of Endemism
Background and aims – The coastal dry forests and woodlands of Cabo Delgado Province (Mozambique), part of the proposed Rovuma Centre of Endemism that is shared with coastal southern Tanzania, are known to support high numbers of endemic and highly range-restricted species. Here we investigate the taxonomic status of three...Darbyshire, Iain ; Goyder, David J. ; Wood, John R.I. ; Banze, Aurélio ; Burrows, John E.
