Plants and their ways in South Africa . eased. point is struck by birds, back fly the petals, and the pollen isthrown some distance as the stamens are freed from confine-ment.

Down by the four-parted ovary there is a littleyellow gland where honey is made. At the entrance of theflower a rocking chair is invitingly placed, made of the twoswinging stamens.
