Abstract

During numerous expeditions to the Western and Eastern Cape Provinces of South Africa, a number of Bulbine species encountered were investigated. After research and consideration of available information and examination of herbarium material in the Bolus and Compton Herbaria, it was decided that four species were as yet unnamed. These new species, Bulbine undulata G. Will., B. rupicola G. Will., B. muscicola G. Will, and B. canaliculata G. Will, are described. Observations on climate, habitat and associated plants are included. The growth habit related to their environmental niches is discussed and where appropriate the new species' closest affinities are commented on. An accurate line drawing has been included for each species showing all-important morphological features coupled with several colour plates. All the new species possess interesting leaves and three occur under extreme climatic conditions in close association with other succulent plants.
