The tree species Gilbertiodendron newberyi Burgt (Leguminosae: Caesalpinioideae) is described and illustrated. The new species is related to G. ogoouense (Pellegr.) J. Léonard s.s. Trees of G. newberyi can grow to 51 m high and 197 cm trunk diam. The new species is ectomycorrhizal, grows gregariously, and presents ballistic seed dispersal. G. newberyi is endemic to Korup National Park in Cameroon, and is assessed as Endangered D under the criteria of IUCN.

The authors would like to thank Professor David M. Newbery of the Institute of Plant Sciences, University of Bern, who designed and supervised the ecological research that resulted in the discovery of the new species. The field research for the present study was mainly funded by the Swiss National Science Foundation. The Bentham-Moxon Trust of the Royal Botanic Gardens, Kew also funded a field trip. Dr George Chuyong (University of Buea) coordinated the field research. The Cameroon government is thanked for permission to carry out research in Cameroon. The conservator of Korup National Park, A. Kembou, permitted access to the site. J.-M. Onana, head of the National Herbarium of Cameroon, is thanked for cooperation. Moses Elangwe climbed the tree from which the type was collected. Jackson Motoh, a young and promising field botanist who helped with much of the field research for this study, sadly passed away on 30 May 2009. Sylvanos Njibili and Charles Okha provided field assistance. Melanie Thomas translated the diagnosis into Latin.
