The genus Jumellea Schltr. is revised for the Comoros Archipelago (Grande Comore, Anjouan, Mohéli, Mayotte). Six species occur on the islands: Jumellea anjouanensis (Finet) H. Perrier, J. arachnantha (Rchb. f.) Schltr., J. arborescens H. Perrier, J. comorensis (Rchb. f.) Schltr., J. maxillarioides and J. pailleri F.Rakotoar. These species are not the same as Schlechter covered; Jumellea arborescens, J. maxillarioides (Ridl.) Schltr. and J. pailleri were added to the list whereas Jumellea phalaenophora was removed since its presence in Comoros archipelago is doubtful. Jumellea gladiator (Rchb. f.) Schltr. is a synonym of J. arachnantha (Rchb.f.) Schltr. Three species of Jumellea are endemic to the Comoros archipelago whereas the three other are also present in Madagascar.
