“ As the present work is intended for the use not only of botanists, but also of colonists and travellers in Africa, who take an interest in botany, I have used, wherever it was possible, as distinctive characters, those which are visible to the naked eye in a plant in flower, being careful, however, not to deviate too much from the natural system. ”

Perianth in the male flowers of 3-6 segments, in the female 3-lobed or wanting. Stamens as many as and opposite the perianth-segments, sometimes one of them abortive. Ovary inferior or naked, 1-celled. Ovules 1-3, pendulous from a central placenta or from the apex of the cell or adnate to the wall of the ovary, without coats.
