Regardless of the continent, man has a relationship with plants, but each community ritualizes its relationship with its environment according to various factors. This relationship is often distinct from the practices of other neighboring communities and influenced by the language of communication. This research aims to analyze the relationship between sociolinguistic communities of the Banwa province in the western part of Burkina Faso, and the species Ceiba pentandra (L.) Gaertn. The fieldwork based on an ethnobotanical survey involved 267 people chosen at random and divided into three age groups comprising men and women, most of whom are illiterate. It essentially emerges from the study that the values of the indices of diversity and equitability of knowledge are low according to gender, and according to age. These values indicate an unequal distribution of knowledge of the species between respondents. In addition, the study revealed 6 forms of uses of the products of the species and among the different parts of the species, the leaves are more in demand than the bark and the fruit.
