The Herbarium at the Royal Botanic Gardens, Kew is one of the largest repositories of preserved plant specimens in the world, and one of the most relevant scientific institutions for African botany. The Buffelskloof Herbarium has enjoyed informal co-operation with Kew for many years but, now a more formal Memorandum of Understanding between our two organisations has been signed, thereby strengthening the flow of scientific information between Buffelskloof and the Royal Botanic Gardens.
