摘要：
A synopsis of the exindusiate species of Dryopteris occurring in the area of the Flore d'Afrique Centrale (D.R.Congo, Rwanda, Burundi) is provided. Three species occur in the area. Dryopteris schizopaleata sp. nov., a new species from Rwanda, is described here. It differs from all other Dryopteris species occurring in the area in the stipe scales that are broadly ovate, with a fimbriate apex, divided into long uniseriate, irregular fissures and without glands. D. manniana is recorded for D.R.Congo, Rwanda and Burundi. D. ruwenzoriensis occurs in the Ruwenzori mountains in Eastern D.R.Congo and Western Uganda, and the Virunga Volcanoes in Eastern D.R.Congo and Rwanda. A key to the three species is provided.
