The usual function of floral nectaries in plants is to attract and reward pollinators, while extra-floral (foliar) nectaries function in the defence of the plant, attracting ants and other insects that can act as bodyguards (Beattie 1985). In a few plants these functions have been reversed, with floral nectar used to attract bodyguards (Dominguez et al. 1989) or foliar nectar used to attract pollinators, Poinsettias, L. are a well-known example (Thorp & Sugden 1990).
