Contribution to the taxonomy of Garcinia (Clusiaceae) in Africa, including two new species from Gabon and a key to the Lower Guinean species

Garcinia has some 260 species and is often regarded as a genus with a difficult taxonomy. No recent treatment is available for the botanically rich Lower Guinea phytogeographical region. This study aims at partly filling this gap. First, several taxonomic problems are solved. G. chromocarpa is reduc...

G. chromocarpa is reduced to a variety of G. quadrifaria. G. gnetoides and G. granulata are both synonyms of G. quadrifaria.
