The book is an unusually exploration of the ethnobotanical study, through interdisciplinary approach, that combines 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 the African ethnic groups, which provides for a scholastic challenge to prove other wise.
The subject matter is drawn from the general botanical topics, viz 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 for evidence to recognise that, although unwritten, the African Traditional Plant knowledge is not muddled, as first impressions might suggest.
