This book contains an unusual exploration of ethnobotany, combining linguistics, botany, and anthropological aspects. It gives an in-depth account of the practical life of the Digo in their day-to-day knowledge and conception of the plant world. The Digo were involved in the study as a representative of African ethnic groups. The subject matter is drawn from the general botanical topics, including plant description, naming, identification, and classification. The coverage, however, is incomplete without considering the fields of plant knowledge application such as agriculture and healing. The book provides evidence to recognize that, although unwritten, African traditional plant knowledge is not disorganized, as first impressions might suggest.
