Portrait of Franz Thonner Franz Thonner,  The flowering plants of Africa (1915)

“ 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. ”
