Resumo(s)
Angola has a great diversity of species and ecosystems and a high level of endemism.
However, knowledge of the native flora remains very incomplete and outdated.
Leguminosae is the largest family in the country, including many species which are
of local or more regional economic importance. Based on an extensive review of
bibliographic sources, natural history collections, and online databases, the checklist
of Angolan Leguminosae plants was updated, including data on their native distribution,
conservation status, and principal uses. The endemic taxa were the subject of additional
investigation, including the main habitat, the number of collections preserved in herbaria,
and the locality of the first collection. We identified 953 Leguminosae taxa occurring
in Angola, of which 165 are endemic to the country. Among the 180 genera found,
Crotalaria (136) and Indigofera (96) have the highest number of taxa. Almost half of the
studied species have important applications, mainly in traditional medicine (385), forage
(267), timber (188), and food (120). Nevertheless, only 27.7% have been assessed
according to the IUCN Red List and 10 species are classified as threatened. Thirty-three
endemics are known only from the type specimen, revealing the lack of knowledge on
these species and the need for further field research. More than 30 type specimens
were collected in the Serra da Chela, which highlights the importance of this region for
biodiversity conservation
