Knowltonia capensis (Brandblare) is an attractive, shade-loving plant of the family Ranunculaceae, that is indigenous to the Cape and Kwazulu-Natal regions of South Africa. The centre of this plant's natural distribution is the Eastern Cape, where it is also most common. However, it can be found to the east in Natal, and as far west as Cape Town, where the plant's western relative Knowltonia vesicatoria is more common. Throughout this area, it grows under trees and in other shady spots, especially in dense afro-montane forest.
