Species of the Corchorus genus: Identification, nomenclature and socio-economic role in Burkina Faso

---

Résumé

Indigenous leafy vegetables play a significant socio-economic role for the local population. However,
most of them used at the local level have not been studied a lot and their nutritional values are less
implemented. This study focuses on the local nomenclature and the socio-cultural services of the
species of Corchorus genus. Therefore, a collection followed by an ethnobotanical survey was carried
out in 22 provinces of Burkina Faso during which a total of 450 people were surveyed. Four species of
Corchorus genus, namely Corchorus olitorius, Corchorus tridens, Corchorus aestuans and Corchorus
fascicularis were identified. The local names of these species vary from 1 to 4 names depending on
ethnical groups. However, differentiation criteria related to status, productivity and/or preference of
populations, pubescence and colour of plant are generally used to differentiate the species. All
identified species are used as leafy vegetables and for the preparation of very tasty drinking (Dolo),
because of their mucilage. As for medicine, 25.33% of the people surveyed gave information on
illnesses such as anemia, stomach aches, and malaria treated with Corchorus genus species.
Considering the socio-economic value of these species for the local population, research programs on
its valorization through varietal improvement must be initiated.
