Abstract
The pollination syndromes of Leonotis (PERS.) R. BR. are discussed. Or nithophily accounts for most of the nutlets set in perennial Leonotis species but in the annual species [L. nepetifolia (L.) R. BR.] autogam y prevails. Leonotis species are predominantly pollinated by a variety of sunbirds, although bees are also involved. Nectar is sucrose-domin ant in perennial species but hexose-dominant in the annual.
