Nomenclatural notes: —When describing C. ituriensis, De Wildeman (1921) cited the specimen J. Bequaert 2153, but did not indicate the herbarium of deposit. By citing the deposit herbarium (BR) Polhill (1964) performs the first lectotypification step. Based on this scenario, we perform a second lectotypification step (ICN Art. 9.17) and designate the specimen at Herb. BR with barcode 0000008968227! as lectotype, because this specimen has more leaves and flowers compared to the other specimens of the BR herbarium.

Taxonomic notes: —Synonym of Trema guineensis (Sattarian et al. 2006) .
