A Congo Basin riverine coffee that tolerates waterlogging and readily hybridizes with robusta, giving hybrids such as Congusta.
*Coffea congensis* was described by A. Froehner in 1897. It is an evergreen shrub reaching about 7 m, native to primary and riverine forest along the Congo, Oubangui and Sangha rivers. Checklists list the Democratic Republic of the Congo, Central African Republic, Congo, Cameroon and Gabon. It has a strong tolerance to waterlogging, which is rare among coffee species. Its fruit are about 9 to 17 mm long and turn red when mature, with seeds about 12 mm long.
It readily hybridizes with *Coffea canephora*, and the hybrids include Congusta from Java and the CxR cultivar from India. PROSEA notes its value in interspecific breeding, especially to bring improved quality into canephora.
History
