While some African Floras were continuously revised and several are now almost completed, the Flora of Angola’s ‘Conspectus Florae Angolensis’ still remains incomplete. This applies also for Droseraceae and the genus Drosera . Our study aims to provide an identification key for Drosera of Angola and the Democratic Republic of the Congo, including all morphological characters of the different Angolan and Congolese taxa. Loans from different herbaria were studied. A list of important morphological characters was combined with data obtained by observations and measurements. Beside the identification key, nine species descriptions with drawings of the main characteristics, distribution maps and SEM-pictures of pollen and seed morphology are provided. The possibility of hybridisation is discussed. Despite difficulties such as varying morphology or hybridisation in some species, the identification key enables researchers to identify specimens by morphological characters.
