The species of the Bomarea setacea complex (subgenus Bomarea, Multiflorae group) are examined. Their morphology, leaf anatomy and epicuticular wax is studied. The variability of the population, their ecology and habitat preference is examined in the field. 5 species are recognised: B. crassifolia, B. crocea, B. endotrachys, B. purpurea and B. setacea. The species are distributed from Colombia to southern Peru. They are all very similar to each other, but in several regions two species occur sympatrically.
